As one of leaders of how to sharpen a fly cutter on a milling machine industry, SBM always seeks innovation & excellence.
Fly cutting, which is also called single point milling, is one of the most versatile milling operations. It is done with a single-point cutting tool shaped like a lathe tool bit. It is held and rotated by a fly cutter arbor. You can grind this cutter to almost any form that you need, as shown in Figure 8-34. Formed cutters are expensive. There are times when you need a special form cutter for ...

05.10.2017· With regard to speeds, you are essentially using a single point milling tool so the usual formula for speeds will work as a starting point: RPM = SFM X 3.82 / Diameter of the fly cutter's path. For example, if you were to try to fly cut a 3" swath in mild steel, you would have 100 X 3.82 / 3" = 127 rpm. This is a starting point and you would try speeds above and below that to optimize the cut ...

A fly cutter provides a single cutting surface, which isn't as fast but is much more uniform and develops into a smoother surface. Cost can also be a factor. We've seen Tormach customers use large face mills on their machines, but those tools are expensive – and so are the inserts at $10-$20 each. If you have upwards of $600, or much more ...

Also known as fly cutters, these clamp onto tool blanks (sold separately) to machine flat surfaces. As the cutter rotates, the tool blank creates a wide, shallow cut on the face of the workpiece. An alternative to face milling cutters for intermittent and light duty use, these cutters allow you to remove and hand-sharpen the tool blank when it becomes worn.

I'd set the rpm to something close to that suggested for cast iron sfm (refer to feeds & speeds in Machinery's Handbook- probably something between 40-100 rpm), and put a radius on the cutter edge (and correct the tram). That much radius out from the spindle may be unavoidably limber, particularly on a light mill- so go easy on the depth of cut & feed.
