Poetry in motion! A CNC flycutter is a beautiful thing.  You may think of it as a single point cutter used on a mill, but that’s just the beginning. A CNC flycutter lovingly faces any metal for a blemish-free finish. Every face mill knows there are times that it’s not up to the job of a flycutter.

This milling machine has too many cutters for a super finish

Single Pass for a Super Finish

Getting a super finish with a face mill isn’t easy. You can manually adjust the cutting height of each insert individually to 0.0001″. What a pain! Or, just remove all cutters except one. Now your face mill is pretending to be a flycutter. Why not just use a flycutter? But the best finish is achieved in a single pass. Cut from right to left. This is what the CNC pros recommend to keep the chips going away from you.

A CNC flycutter allows you to cut one pass the width of the metal. That’s how you get the uniform finish. Do that with a facing head! You’ll make several passes and each pass leaves marks where the cuts overlapped. Now instead of a super finish you have a so-so finish. Flycutters cut shallow too. That’s another secret for a super finish.

CNC Flycutters Make a Great Gift

CNC tooling isn’t cheap. But the CNC flycutter isn’t that expensive. It’s a great gift for any machinist. Every machinist wants a variety of  flycutter sizes. So, you can step in at the holidays and fill the gaps in their tool box. Get them a small cutter for small workpieces or a larger cutter if they work on bigger pieces. Either way, they will finish in one wide swath and thank you for it.

Buy an entire high quality flycutter set for $125.00 at The Tool Company. You’ll buy a quality flycutter and a great gift. Or, buy an individual cutter for around $40 to $50.

A fly cutter is any single point cutter attached to the mill.  They are a must have finishing and facing tool.  Fly cutters may be more common in the manual machine shop, but CNC machinists know that fly cutters win over face mills when it comes to the best finish. That’s because fly cutters clear a large swath with each pass.  Make fewer passes and get a better finish.  It’s a low-tech tool for a high-tech finish.

cnc fly cutter for precisionWhat Makes a Fly Cutter Great

A fly cutter is a cylindrical body that holds a cutter.  It’s not the best tool for carving out lots of material, but it is dynamite for removing small amounts.  That’s why it is a great finishing tool.

Finishing with a face mill isn’t the same. Face mills use multiple cutters.  And multiple cutters inserted into one tool is a recipe for a poor finish if the inserts are not exactly the same height. Exactly.

A single cutter is the best option when need the smoothest finish. You can get a face mill to do the job by removing all the cutters but one. But why would you? Just start with a fly cutter!

CNC fly cutters are single point cutters that you attach to a computer controlled mill.  They are the finishing and facing tools no shop can be without.  There may be more fly cutters in a manual machine shop, but CNC’ers know know that a fly cutter beats a face mill every time for a superior finish. That’s because fly cutters cut a larger swath on each pass.  As you know, the fewer the passes, the smoother the finish.  It’s a low-tech tool for a high-tech finish.

CNC Fly Cutters Rock

CNC fly cutters are just a cylindrical body that accepts a tool for cutting.  It’s not the tool for removing large amounts of metal, but it is perfect for shaving off very small amounts.  Fly cutters rock the finishing world.

Face it, finishing with a face mill just doesn’t cut it. All puns intended. Face mills use multiple cutters.  When you put multiple cutters into one tool you get a bad finish if the inserts are not exactly the same height. And, you know they won’t be.

For the best possible finish, a single cutter is always the best solution. A face mill can only do the job if remove all the cutters but one. Still, it won’t be the same. So,  just start with a fly cutter!

If you need a precision finish, you need a fly cutter. You just can’t beat the incredible finish you get from  a fly cutter. Fly cutters were recognized as an invaluable tool in the machine shop as far back as 1884.  Sure, some CNC machinists use face mills for finishing; fly cutter setbut experienced machinists know that the secret weapon to for the smoothest aluminum finishing is a fly cutter with a diamond insert. It’s the first choice for  a mirror finish.

 

 One Pass Finishes with Fly Cutters

Make one pass for the finest finish over a large surface area. That is the fly cutter advantage. Even Ingersoll Rand recommends that their face mills be operated as fly cutters for the finest finish. They even tell you how to modify their face mill. So, the obvious question is why should make a face mill act like a fly cutter when you should just use a fly cutter in the first place? For the right finish at the end, you must start right inn the beginning.

Using a Fly Cutter

Finishing is just one use of a fly cutter. Use a fly cutter to machine small fly cutters an involute on a gear tooth or cut clearance notches in pistons. It’s the perfect tool for the job. Need to make circular cuts and notches in metal? The fly cutter is the obvious choice. The only limit is your imagination. Need to mill an odd shape? Use a fly cutter.

We get lots of questions about tools in general. We get loads of questions about the fly cutter. Here are some of the most commonly asked questions about fly cutters.

Should you use a face mill or a fly cutter for the best finish?  Fly cutters always gives the best finish. There is no question about it. Fly cutters utilize just one cutting surface.  Use a fly cutter larger than the work area to get a clean finishing cut in a single pass. The quality of the finish goes down with every pass you make. Take all the cutters off your face mill except one to convert a face mill to a fly cutter.

CNC  fly cutter made in the USACan you use a fly cutter to finish aluminum?  Yes. Pick your fly cutters with care.  Aluminum is soft.  You need a hard cutter (like PCD) to get a good finish.

How do you grind the bit?  Remember the geometry of the cutter.  The end of the tool does all the cutting.  Grind the rake into the end of the tool.  The bottom of the bit determines the surface smoothness.

Are feeds and speeds different for flycutting? Calculate your feeds and speeds with your regular software.  Flycutters generally run at lower RPMs, but your software knows for sure.  Depend on your software to calculate the correct feeds and speeds. There’s no shortage of software.

How do you remove material quickly?   Use the face mill first if you need to quickly remove material. A face mill will give you deeper cuts and faster chip removal.  Make a fly cutting pass for the final finish once the material is removed.

cnc fly cutter setIs tramming necessary?  Yes, if you want to do the job right.  Most of the time we hear this question because  someone is noticing a dip in the finish.  The problem is the tool; not the tool set-up.  Make sure everything is trammed and up to snuff before the first pass.

Where can I get a good fly cutter? Some home machinists make a stab at making their own fly cutter. A serious machinist knows that’s not the best idea.  The best idea is to get a fly cutter from The Tool Company.  Here’s why.

Large Diameter Fly Cutter

The Tool Company sells large diameter sizes.  The larger the cutter, the fewer the passes.  Fewer passes equals a finer finish.

Stability and Balance

Finishing cuts require maximum stability and balance.  At The Tool Company, you get a fly cutter that is made with a larger 1/4-20 alloy set screws. That means better cutting blade stability. Run at higher RPMS with a balanced flycutter.

Save Time and Money

The Tool Company sells fly cutters made by Sierra American Multi-Systems. These fly cutters use 1/2” and 3/8” fly cutter bits. You can make larger cuts and this means your job goes faster. Since time is money; saving time saves money.

Ask any manual machinist and they will tell you if you want a very fine finish, a fly cutter is the only tool to use. For most finishing jobs,  CNC’ers use a face mill, but the best CNC’er knows that for the best finish, you’ve got to use a fly cutter.

 Face Mill versus  Fly Cutter

face mills don't finish as well as fly cutters

Nope!

Someone once said that the finest aluminum finish on Earth is achieved with a fly cutter with a diamond insert.  Well if that is true for a manual machinist it is most certainly true for a CNC machinist as well.  Sure you can get that face mill to spin at a higher speed, but slow and steady is what gives you a lustrous, brushed finish.

In order to get your face mill to produce that finish without any run

fly cutters

Yep!

out you’ve got to remove all the cutters but one.  That means you just turned your face mill into a fly cutter.  So why not just start with a fly cutter?

You know that your fly cutter can get into places your face mill just can’t go. So don’t use a face mill when a fly cutter is the right tool for the job.

Fly Cutter Tips

Use these tips and you can get a flawless finish on even the toughest to work materials  like titanium or stainless steel.

Feeds and Speeds – With the right combination of feed rate and speed and you can machine anything. A material is only difficult because it can only be machined in a small range and has no tolerance once you get outside that range.  Use a good calculator like the CNC Cookbook to account for all the variables.

Coolant – Certain materials machine just work better with coolant and some materials require coolant to be machined. That means you should use some form of coolant. You don’t need a flood if a mist will do. Coolant is important to stop stainless from hardening.  You know you need it to stop aluminum chips from welding to the cutter.

Keep Chips Clear – Speaking of chips, you have to make sure that you keep the chips clear. It doesn’t matter if you use a liquid coolant or blow an air mist, just keep those chips clear.  Recutting chips that aren’t cleared is just as bad as double dipping your potato chip. Ain’t nobody happy. Those chips just make the tool work harder. Just clear chips as fast as they are made.

Use the Best Fly Cutter

Just like anything else, your finish is only as good as your start. Make sure you start with the finest cutter available. The Tool Company only carries the finest fly cutters They are available in 1½”, 2”, and 2 ½” diameters. They are heat treated for a longer life and manufactured to reduce chatter.

Last post we talked about the need for precision when cutting. However, not all precision cuts require a precision saw.   You can also use a fly cutter for very fine, fly cuttersprecision cuts.  As a matter of fact you just about can’t beat the extraordinary finish you get when you use a fly cutter. Even in the early days of machining, fly cutters were recognized as an invaluable tool in the machine shop.   These days some CNC machinists will use a face mill for finishing work; but experienced machinists use a fly cutter with a diamond insert as their secret weapon for the finest aluminum finishing.

Finish in One Pass with a Fly Cutter

To get the finest finish over a large surface you should only make one pass. A face mill isn’t going to let you do that in only one pass. That’s what why a fly cutter is superior to a face mill.  One manufacturer actually recommends that their face mills be operated as fly cutters to achieve the finest finish. It makes no sense to modify your face mill to act as a fly cutter. If a fly cutter is what you need, then start with a fly cutter. You can’t get the right finish if you don’t use the right tool.

Fly Cutters Do More Than Finish

If you are cutting an involute on a gear tooth or making clearance notches on pistons, then a fly cutter is the right tools for the job.
