When you need precision you need a fly cutter. It’s hard to beat the superior finish you get from use of a fly cutter. As far back as 1884, fly cutters were recognized as an invaluable tool in the machine shop. While some CNC machinists use face mills; experienced machinists know that the secret weapon to for the finest aluminum finishing is a fly cutter with a diamond insert. It’s the first choice for to achieve a mirror finish.
Fly Cutters for One Pass Finishes
The finest finish over a large surface is going to be made with one pass. That is what makes a fly cutter superior to a face mill. As a matter of fact, Ingersoll Rand recommends that their face mills be operated as fly cutters if the finest finish is necessary. They actually tell you how to modify their face mill. So the obvious question to ask is why should you try to make a face mill act like a fly cutter when a fly cutter is the proper tool? You shouldn’t! If you want to end right, you need to start right.
Fly Cutter Usage
Finishing is just the start of using a fly cutter. Fly cutters are the perfect tool for cutting an involute on a gear tooth or cutting clearance notches in pistons. When you need to make circular cuts and notches in metal, the fly cutter is the obvious choice. Fly cutters are only limited by your imagination. If you need to mill an odd shape, you need a fly cutter.
