90000 Tips For Buying Your First Milling Machine 90001 90002 If you’re interested in making things (and since you’re reading this, we’re going to assume you are), you’ve almost certainly felt a desire to make metal parts. 3D printers are great, but have a lot of drawbacks: limited material options, lack of precision, and long printing times. If you want metal parts that adhere to even moderately tight tolerances, a milling machine is your only practical option. There is, after all, a very good reason that they’re essential to manufacturing.90003 90002 However, it can be difficult to know where to start for the hobbyist who does not have machining experience. What kind of milling machine should you get? Should you buy new or used? What the heck is 3-phase power, and can you get it? These questions, among many others, can be positively overwhelming to the uninitiated. Luckily, we – your friends at Hackaday – are here to help give you some direction. So, if you’re ready to learn, then read on! Already an expert? Leave some tips of your own in the comments! 90003 90006 What Kind of Milling Machine Do You Need? 90007 This is a vertical milling machine, with a head that rotates, tilts, and swivels (photo courtesy of Wikipedia) 90002 Before we get into the details of what configuration of milling machine you’ll most likely want to buy, let us first point out that we’re only going to be talking about 90009 manual 90010 milling machines in this guide.CNC mills are a whole other beast, and they’re going to get a guide all to themselves. Manual and CNC mills share a lot in common (CNC mills are often just converted manual mills), but CNC mills have additional requirements that would over-complicate this article. So, we’re just covering manual machines in this post. 90003 90002 Modern milling machines are divided into two basic types: horizontal and vertical. This determines whether the machine’s spindle axis runs up and down, or side to side.Both types of machine will often have heads, columns, and tables that tilt or swivel, which means both kinds can be used for a lot of the same tasks. However, certain jobs will be easier on one machine than the other. 90003 90002 The difference between the machines, in practice, is more pronounced than just which way they’re oriented. A vertical machine will have the table mounted perpendicular to the spindle’s zero-tilt position, while a horizontal machine will have the spindle mounted parallel to the plane of the table.This introduces a fundamental difference in what kinds of jobs are practical on each type of machine. 90003 Notice how the overhead arm of the horizontal milling machine braces the spindle arbor on both sides (photo courtesy of Kent USA) 90002 A horizontal milling machine’s primary strength is the over arm, which constrains the rotating arbor on two sides. This gives it incredible rigidity, and allows the machinist to take very heavy cuts that would introduce more side load then a vertical machine could handle.The strength is so high that it’s entirely possible (and common) to stack multiple cutters on the arbor in order to cut, for example, a flat table with slots all in a single pass. This makes it well suited to surfacing jobs, cutting grooves and slots, and similar tasks where the part is flat in one axis. 90003 90002 The downside, of course, is that it’s much more cumbersome (and sometimes impossible) to make parts that have cuts in all axes. This is where a vertical milling machine excels: in versatility.You’d be hard pressed to find a job that a vertical mill can not do – though it’s sometimes a lot more time-consuming than a horizontal mill, depending on the part geometry. 90003 90002 Now that you know the difference, you probably already know which one you want. But, just in case, we’ll say that you almost certainly want a vertical mill. Horizontal mills are great for a small portion of tasks, but those are also tasks that most hobbyists will not often perform. The versatility of a vertical mill lends itself well to the varied and diverse tasks that hobbyists lean towards, in contrast to the specialty production work horizontal mills are generally used for.90003 90006 Vertical Mill Features That Matter 90007 90002 Hopefully, you’ve decided that a vertical mill is the best choice for you, otherwise this section is not going to be very useful. Assuming you have decided on a vertical mill, you’re probably curious about which features to look for, and are wondering what actually matters. Covering every detail on the subject would take an entire book, but we’re going to go over some of the most important things to consider. 90003 90026 Should you buy brand name? 90027 90002 This is a question that drives a lot of purchasing decisions, and milling machines are no different.So, does it matter? Yes and no. Milling machines have been around for a 90029 long 90030 time, and there really are not any trade secrets when it comes to their construction. It’s well-known what makes a good machine, and what does not. Theoretically then, any manufacturer can follow these design principles and make a high quality machine. 90003 90002 Reality, unfortunately, does not live up to that promise. There are two reasons for this: manufacturing quality and cost. In order to keeps costs down, many manufacturers will cut corners.They might use poor quality materials, under-powered motors, and so on. Even if the manufacturer is not purposefully cutting corners, it’s entirely possible that they might just be incapable of high-quality manufacturing. Poorly made lead screws, imprecise machining, and loose tolerances can all leave you with a mill that is frustrating to use and which can not hold tolerable precision. 90003 90002 Therefore, it’s a good idea to buy a proven machine. Usually, that means going with a respected brand.But, some less expensive brands still produce quality machines (often clones of more expensive models). They may have fewer features, or less robust motors, but could be enough for your needs. Just be sure to read some reviews from people doing real work with them. 90003 90026 Size Matters 90027 90002 Small desktop milling machines can be tempting, but it’s best to avoid them if you’re planning to mill metal. Think about the last time you had to drill a hole in steel, or had to cut off a piece with a hacksaw.It’s difficult work, and takes a lot of force. Your milling machine needs to be able to apply that kind of force without flexing at all – even a little bit of flex with ruin any chances of milling a part with respectable tolerances. 90003 90002 For that reason, the frame of the mill needs to be as heavy and rigid as possible. A small desktop machine will almost certainly be unable to mill anything harder than aluminum, and even then it’ll be imprecise. The wisest choice, if you want even moderate precision, is to buy a mill that’s as large and heavy as you have space for.90003 90026 DRO and Power Feed 90027 90002 A DRO (digital readout) is a module that can be added to each axis of a milling machine. Some machines come with them, others have them available as upgrade packages. Kits are often available to retrofit mills that did not originally have them as an option as well. A DRO gives you a display that tells you how far you’ve moved the table (or quill), which makes pretty much every operation much easier. 90003 A 3-axis DRO display and control panel (photo courtesy of Wikipedia) 90002 Using a DRO is not strictly necessary, as all mills have dials for measuring movement.However, reading them can be cumbersome and time-consuming. This is especially true when you consider backlash (slop in the screws), which is easy to compensate for when you have a DRO, since it only tells you how much the table has actually moved, as opposed to how much the handle has moved. 90003 90002 Like a DRO, power feed is something that can be added to each axis, and which many mills come with from the factory. It allows you to toggle a small motor which moves the table for you, so that you do not have to crank the handle yourself.This can dramatically lower fatigue, but can also give you a better surface finish on your cut as the speed stays consistent throughout the cut. 90003 90026 Spindle Motor Horsepower 90027 90002 Like car enthusiasts, machinists make a big deal about horsepower. And, this is not completely unwarranted – the last thing you want is the motor stalling in the middle of a cut. That said, virtually all mills will have some way to gear down the motor to gain torque at the cost of speed. Milling steel requires high torque and low-speed, while aluminum needs the opposite.90003 90002 So, you can certainly compensate for a motor without a ton of power. That may be a good idea, as motor horsepower makes a huge difference when it comes to cost. That said, you should probably avoid a mill that has any less than 1HP. It’s also difficult to find high horsepower electric motors that are not 3-phase. 90003 90026 3-Phase? Huh? 90027 90002 We do not have the room to get into how multi-phase power works, and what it’s advantages and disadvantages are. But, suffice it to say that you almost certainly do not have 3-phase power at home.If you’ve got an industrial space, you may have 3-phase power available, but even then you may not. The point is, many industrial-grade tools have 3-phase motors, which can not be run on standard household single-phase power on their own. 90003 90002 That means that most of you will be limited to mills with single-phase motors. However, that often makes it possible to find 3-phase machinery for significantly cheaper than single-phase machinery. If you find such a machine that strikes your fancy, it is possible to replace the spindle motor with a single-phase unit, or to buy or build a phase converter.90003 90026 What about a mill / drill machine? 90027 90002 A mill / drill machine is basically a drill press that has had a 2-axis table strapped onto it. They’re significantly cheaper than true milling machines, but that’s for a reason. They really do not have the rigidity necessary for real milling, and are really only good for precise hole drilling and very light milling. Other than saving a little cash, there is no reason to buy one, as an actual milling machine can certainly drill too. 90003 90006 Buying Your Mill 90007 90002 By this point, you should have a pretty good understanding of what matters in a milling machine.Now it’s time to dive into how you should go about buying one. 90003 90026 New or Used? 90027 90002 You should seriously consider buying used. Quality mills are machines that are designed to stand up to serious abuse for decades, and you can save a lot by buying used. Local industrial auctions and Craigslist are good places to look. Inspecting used machinery is kind of like inspecting a used car: make sure everything is working, that there is not excessive wear, and that you can see it’s been taken care of.90003 90002 Dirt and grime are okay, that can be cleaned, as long as the important bits are clean, lubricated, and not too worn. Make sure the spindle spins smoothly, has no play (measure run out if possible), and sounds good. Grab the table and jiggle it as hard as you can, and make sure you can not feel any play. Take a look at the screws to see if they’re clean and unmarred. Make sure the ways (the smooth metal that the table slides on) are clean, lubricated, and do not have gouges. If all of those things are good, and you do not notice any other red flags like cracked castings, the machine is probably solid and entirely usable.Age is not generally considered a problem as long as it’s been maintained and serviced. 90003 90026 Getting it Home 90027 90002 Milling machines are heavy; they can be anywhere from several hundred pounds on the light side, to several thousand pounds on the hefty side. Getting one back to your home or shop is not a trivial task. If you’re transporting it yourself, make sure your truck or trailer can handle the load, and that it’s securely strapped down. You’ll also need a forklift of some kind of both sides of the delivery (to load and unload the machine).90003 90002 If, like most hobbyists, you do not have a heavy flatbed truck and your own forklift, you can hire riggers to move the machine for you. Expect to pay at least a few hundred dollars (and sometimes a lot more) to have it moved, even over a short distance. If you know anyone who has this kind of equipment, it’s definitely worth calling in some favors – you’ll need that money for tooling. 90003 90026 Accessories and Tooling to Purchase 90027 90002 Once you’ve got your milling machine home, there are a number of purchases still to make.First and foremost, you’re going to need a decent machinist’s vise. You do not necessarily need to spend hundreds of dollars on a Kurt vise, but you’ll want something that is well machined and which is not going to loosen. A swivel mount is nice to have, but is not a necessity. 90003 90002 Next, you’ll need a way to hold your end mills. For this, you’ll need collets or end mill holders that match the arbor on your mill (this information should be readily available in the specs). You’ll probably want to start with two or three of them in various sizes, so that you can use end mills with different shank sizes.90003 A set of R8 collets for a variety of shank diameters (photo courtesy of Enco) 90002 Speaking of end mills, you’ll want to order a bunch. You can buy them in bulk cheaply via eBay, which is a good idea when you first get started. Buy carbide, and a handful in a few different sizes. Make sure the shank sizes match the collets / end mill holders you bought. Generally, 2 flutes are recommended for aluminum and 4 flutes are recommended for steel. If you’re not sure what you’ll be cutting, you can get some of each, or get some 3 flute end mills as a compromise.Expect to pay $ 10 and up per end mill (yes, tooling gets expensive). 90003 90002 Finally, you may want to consider a coolant system. These come in a few different variations, but flood coolant is usually the easiest to get setup. Despite the name, coolant does a lot more than just cool; it also lubricates and flushes away chips. Coolant systems can fairly easily be added to any milling machine, and many come with them from the factory. 90003 90006 Start Milling! 90007 90002 Now the fun finally starts! You’re going to want to do a lot of experimenting in the beginning.Do research on feeds and speeds (and get a decent calculator for them), what different end mills are good for, and how to perform specific kinds of operations. Do not get discouraged if you break an end mill, that’s why you bought extras. Practice, practice, practice, and soon you’ll be coming up with excuses to make precision metal parts for all of your projects. 90003 .90000 Portal Milling Machine / Milling Machine Lathe Multi-purpose Machine / milling Machine For Metal 90001 90002 portal milling machine / milling machine lathe multi-purpose machine / milling machine for metal 90003 90004 90005 90004 90005 90004 90005 90004 90005 90004 90005 90004 90005 90004 CNC milling is a form of computer controlled machining.

If so, maybe Plunge Milling (also called Plunge Roughing) is the answer. 90007 90006 Plunge Milling is a type of CAM Toolpath, though it can be programmed manually as we will see. The idea, is to rough out a pocket, profile, or 3D surface by plunging either a twist drill, an endmill, or a special-purpose tool straight down into the material.Here’s a typical example: 90007 90006 90011 90007 90006 Plunge Milling a Pocket – Image courtesy of BobCAD … 90007 90006 The graphic shows a typical plunge milling operation for a square pocket, courtesy of BobCAD. As you can see, a chain of holes are plunged vertically with the tool to rough out most of the pocket area. A subsequent finish pass will complete the pocket. 90007 90006 Some good plunge milling video here: 90007 90006 90020 90021 90007 90002 90003 What are Plunge Milling’s Advantages? 90004 90005 90006 I called Plunge Milling a “Secret Weapon” above because it can really save your bacon in some situations.It is designed to take advantage of two important properties: 90007 90029 90030 Twist drills often have much higher material removal rates than endmills. 90031 90030 Most CNC Machines have Z as their stiffest axis. By changing forces from side forces (XY plane) to axial (Z) up and down forces, we get much more rigid cutting. 90031 90034 90006 Taken together, it’s pretty easy to see where Plunge Milling could turn into your Secret Weapon. 90007 90006 Perhaps you have a relatively lightweight or less rigid machine.By taking advantage of the greater rigidity your machine will have in the Z direction, you may be able to get higher Material Removal Rates. Or, you may be able to overcome a chatter problem that’s due to a lack of rigidity. 90007 90006 Older (or cheaper) CNC milling machines that have more slop in the XY axes, less precise interpolation, or slower spindle speeds may also benefit from exercising the Z-axis more via Plunge Milling. Plunge Milling seems tailor-made for the limited rigidity and performance of Hobby CNC machines too, for example.90007 90006 And speaking of a lack of rigidity, Plunge Milling can be ideal for those really deep pockets where side forces are causing so much tool deflection you can hardly make progress at all. Sandvik says Plunge Milling is advantageous any time overall Tool Stick out is more than 4 x Tool Diameter. 90007 90006 How about a Mill-Turn situation where your live tooling is not nearly as rigid as on a pure milling machine? Here again, you may find Plunge Milling is just the ticket. 90007 90006 Plunge Milling can also be just the ticket when your machine’s spindle power is limited, according to Sandvik.90007 90006 90048 90007 90006 Talk about a lack of rigidity-long reach and thin walls make Plunge Milling a natural for this 5-axis turbine application. Image courtesy of Hypermill. 90007 90006 Another way Plunge Milling can help overcome a machine’s limitations is when spindle speed is limited. Plunge Feeds and Speeds may be a little slower than straight up high speed machining. But, if your spindle rpm is the limiting factor, you may not be able to take full advantage of HSM. If that’s the case, Plunge Milling is even more likely to give you the best Material Removal Rates.90007 90006 How about machining a tall thin wall? This is a notoriously chatter-prone situation that may be partially amenable to Plunge Milling. It’s not a total cure, because you’ll still have to manage a finish pass that removes the scallops, but it might allow higher Material Removal Rates without chatter for the roughing pass. 90007 90006 In fact, consider Plunge Milling any time chatter becomes a big problem on a job. 90007 90006 One last special case for Plunge Milling would be corner clearing.When the depth of the corner is greater than about 4 x the cutter diameter that fits into the corner, rigidity issues develop. 90007 90006 Aside from special cases, some shops report that Plunge Milling allows them to do roughing on older machines in the shop that might otherwise go unused. They keep their newer machine centers busy on jobs the older machines can not do, and over shop spindle utilization goes up. That means more profit. 90007 90006 I like the idea of ​​Plunge Milling for Lights Out Machining too.It seems inherently more conservative and less prone to problems like whether coolant is aimed properly or not. 90007 90006 Plunge Milling can be applied to help maintain rigidity in these difficult cases: 90007 90006 90067 90007 90006 Plunge Milling Corners. Image courtesy of Sandvik. 90007 90006 One could imagine doing most of the roughing with an HSM Toolpath and an endmill that is much to large in diameter to get into the corners. Depending on pocket shape, this can clear most of the material without leaving much scalloping.90007 90006 As part of the final finish or an intermediate Semi-Finish pass, we use a much smaller diameter endmill to clear the area of ​​the corner and then we can make an overall finish pass of the entire wall of the pocket or profile. 90007 90002 90003 Plunge Milling Disadvantages 90004 90005 90006 90080 90007 90006 Plunge Milling leaves scalloped edges which may take a fair amount of cleanup or a semi-finishing pass before a true finish pass can be applied. Image courtesy of Sandvik-Coromant.90007 90029 90030 90003 Scalloped Edges 90004: Plunge cutting leaves a scalloped edge (see diagram above) that will have to be cleaned up by a finish pass. Depending on your X and Y stepover amounts, the amount of scallop to be removed could be significant. If it’s more than a single finish pass can remove, an optional semi-roughing pass will be needed to clean up the scallops before the final finish pass can be applied. 90031 90030 90003 Center Cut 90004: The tool used must either be center cutting (leaves out many types of indexable endmill) or the toolpath must allow for a ramp or helix entry to create enough space to start taking partial plunge cuts.If the tool is not center cutting, it also can not cut on a down slope where the feature gets deeper in some places. 90031 90030 90003 2D vs 3D Plunge Milling 90004: Some Plunge Milling toolpaths only support 2D features where the floor is at the same Z, while others can do full 3D Profiling via Plunge Milling. 90031 90034 90006 90099 90007 90006 3D Plunge Milling. Image courtesy of SprutCAM. 90007 90029 90030 90003 Conventional Twist Drills 90004: The point angle on conventional twist drills makes them wander when plunge roughing if the holes overlap too much.You also wind up with a scalloped floor, which is less desirable. This may require flat-bottom tooling such as endmills or twist drills that are specially made for Plunge Milling. 90031 90030 90003 Not the Best Under Favorable Conditions 90004: Plunge Milling is not a general-purpose strategy that replaces all other strategies. It’s best use is when you need Plunge Milling’s advantages: more rigidity and less power required. If those are not problems you need to solve, then Plunge Milling is probably less optimal than other Roughing Strategies such as a High Speed ​​Machining (HSM) Toolpath.90031 90034 90002 90003 Plunge Milling Feeds and Speeds 90004 90005 90006 Our first task is to decide on the X and Y stepovers. 90007 90006 Sandvik recommends starting with a stepover (Cut Width in G-Wizard) of 80% of cutter diameter for the sideways motion of a single pass. 90007 90006 The stepover to move deeper into the material for the next pass is limited by the insert diameter or the maximum Cut Width of any non-center cutting tool. 80% of that value is a good choice as well. Keep an eye out so there’s no skinny stalks sticking up in the corners between the holes.If you see stalks, you need less stepover in one dimension or the other. 90007 90006 Now we need Feeds and Speeds. Our G-Wizard Feeds and Speeds Calculator has special features to help with Plunge Milling. 90007 90006 Let’s work through an example that shows the strengths of Plunge Milling. Suppose we are handed the task of roughing out a pocket that has 1/8 “corner radii, which dictates and endmill no larger than 1/4” in diameter. Next, suppose that pocket is 1 1/2 “deep. 90007 90006 I can already hear the groans out there in the audience-a pocket that deep with such a small endmill is likely to be a bear! 90007 90006 Just to keep things simple, I’m going to choose X and Y stepovers of 0.0625 “for this job. Let’s check Feeds and Speeds with G-Wizard and assume we want to use an HSM roughing strategy like Adaptive Clearing or Volumill: 90007 90006 90132 90007 90006 MRR is not bad at 3 cubic inches / min, but deflection is way too high … 90007 90006 The MRR is not bad at 3 cubic inches / min, but deflection is way too high. This approach is going to chew up tools very quickly with almost 3 thousandths of deflection. 90007 90006 We can use G-Wizard’s Cut Optimizer to see how much stepover is allowable to keep things within deflection allowances: 90007 90006 90141 90007 90006 Cut is almost impossible without too much deflection … 90007 90006 A quick click on the “Cut Width” label has Cut Optimizer taking us all the way down to a Cut Width of only 1.4 thousandths and there’s still a bit too much deflection. We could probably live with that, but MRR is down to a lousy 1.1 cubic inches a minute. 90007 90006 We’re going to lose our shirts on this job if we do not find another way. What about Plunge Roughing? 90007 90006 Click the “Plunge” button to bring up the Plunge Milling Mini-Calc: 90007 90006 90152 90007 90006 G-Wizard’s Plunge Milling Calculator … 90007 90006 G-Wizard’s Plunge Milling Calculator let’s us enter a Step Up (amount to move into material at start of each pass) and a Step Over (amount to move laterally from prior hole on the same pass) and adjusts the feedrate based on those parameters .90007 90006 Here is the result: 90007 90006 90161 90007 90006 Here’s a case where Plunge Milling shines … 90007 90006 Here’s a case where Plunge Milling shines: our MRR is back in the 3 cubes a minute territory of the original HSM scenario, and while the Deflection error is still red, we can ignore it because we’re plunging and there will be no significant deflection while doing that. 90007 90006 Problem solved! 90007 90002 90003 Which CAM Packages have Plunge Milling? 90004 90005 90006 Here is a list of the most popular software from our last CAM Package Survey that shows whether each package has Plunge Milling or not: 90007 90006 90176 90007 90006 As far as differences in Plunge Milling toolpath quality, it’s worth checking on whether your CAM package supports two capabilities.90007 90006 First, does it do true 3D or just 2D Plunge Milling? 3D is obviously much more general while 2D will only work for flat-bottomed features. 90007 90006 Second does the plunge cycle retract away from the wall during the overall retract? This reduces chatter and increases tool life when machining tough materials. Here’s the Plunge Rough retract style jointly developed by WorkNC and Ingersoll: 90007 90006 90185 90007 90006 Retracting from the Wall slightly during Plunge Rough … 90007 90006 Retracting from the Wall slightly during each Plunge Rough stroke can improve tool life by 10 to 15 percent, according to the developers of the technique.90007 90002 90003 What Can I do if my CAM Software will not Plunge Rough? 90004 90005 90006 Normally if your CAM software does not support a particular kind of toolpath, you’re just out of luck. But Plunge Milling may be different, depending on how adventurous you are. A basic strategy for creating your own Plunge Milling toolpath works like this: 90007 90197 90030 Use your CAD Software to generate a grid of holes (circles or whatever you like) within the contours of the pocket or other feature’s outline.Be sure to leave some finish allowance, so you may need to inset the outline by the finish allowance. Depending on how easy it is to keep the circles entirely within the outline, you may have to inset further to leave enough allowance. Your CAD software does most of the work, so you’re relying on its sophistication to pull off the creation of the hole grid. Even if the package is a bit weak in this area, most of them should be able to lay down a grid within a rectangular region or perhaps in a line so you can Plunge Mill a slot.90031 90030 Given the grid of circles, you create a g-code program to plunge the cutter at each circle’s coordinates. This can be as simple as taking a canned drilling cycle and feeding it the list of circle coordinates. 90031 90202 90006 There are certainly embellishments. For example, you could do the fancy wall retract move with a little bit more hand coding. You may also need to deal with entering the pocket, though you could use just have your CAM package generate its entry and then cut and paste that gcode to create a starting point for your Plunge Milling routine.90007 90006 With a little bit of gcode programming familiarity and some decent chops with your CAD software, this is not hard nor does it need to take very long. 90007 90006 Here’s an example I partially worked through in Rhino3D: 90007 90197 90030 Start with the outline of your pocket. Inset that outline by a finish allowance. Here is the contour with an inset: 90031 90202 90006 90214 90007 90006 The contour of a pocket wall with an inset for a Finish Allowance … 90007 90006 2.Drop a circle of the endmill’s diameter down and make it tangent to somewhere convenient on the inset contour: 90007 90006 90221 90007 90006 3. Create an array of the circles with the X and Y stepover you want to use: 90007 90006 90226 90007 90006 I did not get the grid quite large enough! 90007 90006 4. Trim any excess circles that extend too far out-of-bounds: 90007 90006 90233 90007 90006 5. Adjust remaining circles at the edges so they’re tangent to any inset contour edges they intersect: 90007 90006 90238 90007 90006 That’s about all there is to it.You now have a CAD drawing that shows where the holes for the plunge strokes need to go. 90007 90006 Import it into your CAM package and treat just like trying to drill all those holes. It’ll generate the gcode which you can then further tweak as needed. 90007 90006 I did not finish with the CAM part, but the CAD work only took 10 minutes and I did not use any shortcuts. It’s not hard to do if you want to play with Plunge Milling a bit. Programming something like this to clear a corner or two would be even easier.90007 90002 90003 Plunge Milling Cutters 90004 90005 90006 You have multiple choices of cutter when Plunge Milling: 90007 90029 90030 Conventional End Mills and Indexable Tools 90031 90030 Twist Drills 90031 90030 Specialty Cutters made for Plunge Milling 90031 90034 90006 G-Wizard makes it easy for you to evaluate which one will perform best for your jobs given all the variables that are in play. 90007 90006 One shop found that button cutters (round insert indexable tooling) worked especially well for their needs.Normally, Plunge Milling Specialty Cutters use flat-bottomed inserts, but the round inserts were much less prone to chatter than the flat-bottom inserts. 90007 90006 One thing to be careful of when Plunge Milling is any cutting near the center of the tool. Many indexable tools can not cut in the center and many end mills are also not center-cutting. That means you’ll have to plan your stepovers so no center cutting is called for. You may need to create a starter hole with a drill (indexable or otherwise) to avoid center cutting issues.90007 90266 Plunge Milling with Twist Drills: Chain Drilling 90267 90006 Back in the days of Manual Machining, chain drilling was pretty common with tough materials: 90007 90006 90271 90007 90006 Image courtesy of Home Shop Machinist … 90007 90006 The technique worked and allowed a Bridgeport to open up a lot of material quickly. But, there are disadvantages. Twist Drills do not like overlapping holes and interrupted cutting too much, so mind your stepovers accordingly. No more than 40% overlap can be tolerated if the drill has a conical point, and even this much can lead to a lot more wear.This may or may not lead to good Material Removal Rates, so this is another case where experimenting with a few scenarios in G-Wizard can really help refine your approach. Also carbide twist drills do not like the shock associated with plunging too much. HSS or indexable tooling may be a better bet. 90007 90006 Another issue with Twist Drills is the holes are not flat bottomed. There are versions available that are flat bottomed, both indexable and solid, so consider those. Otherwise, you either want a through situation (a hole not a pocket) or you’ll have quite a lot of finish work to do on the scalloped floor of the pocket.90007 90002 90003 I want to know more! 90004 90005 90006 Like I said, Plunge Milling can be a powerful secret weapon in your CNC arsenal.
