how to sharpen a fly cutter on a milling machine

CGTK - Flywheel Fly Cutter

The fly wheel fly-cutter can cut over the entire width of the milling machine's table in one long arc and produces a very good finish on the top of the part it's cutting, even when taking a relatively deep cut. Like all fly-cutters, it does a very good job of sending swarf everywhere!

I need ideas for sharpening milling cutters.

2011-8-16  I got my horizontal mill operational but I have no sharp cutters. I got a box full of dull cutters of all discription but they have been thrown around in the box for a lot of years. I need ideas on ways of getting set up to at least be able to sharpen the straight cutters. I have a lathe and tool post grinder.

Using a fly cutter The Hobby-Machinist

2017-10-5  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.

Proper grind for a fly cutter? - The Home Machinist!

2012-5-28  A small radius that runs from one side of the tool to the other (bottom to top when it's installed in the fly cutter), and parallel to the end of the tool. A small radius stoned on the point (about .02") should provide for a decent finish. Stone the side, end, and top of the tool (in the chip breaker). Much easier to grind than to describe.

Cutters for horizontal milling john f's workshop

Cutters for horizontal milling. The cutting tools that fit the horizontal arbor are in the form of circular disks with the cutting teeth round the outside edge. Typical horizontal cutter – 6. This disk has a hole in its center that accurately locates it on the arbor. The spacers can be used to position the cutter at any position along the arbor.

I need ideas of how to sharpen milling cutters

2011-5-2  The cutter is "freewheeling", in this case on centers but sometimes in a collet, often with an air bearing. You could spin the cutter in one direction, like a ratchet. (Not while grinding of course!) Typical usage has one hand maintaining contact with the cutter tooth and the finger to prevent chatter, and the other hand traversing the machine ...

Creating a Fly Cutter Bit The Hobby-Machinist

2012-11-24  Great comments, thanks for pitching in. Dennis, the fly cutter is a great tool for milling a large surface area on metal stock. It cleans up a surface very nicely, creating a smooth level plane. I envision using it to mill material down to a target thickness.

Fly cutter tool shaping - The Home Machinist!

2008-1-25  Basically, fly cutters cut on the end of the bit as it traverses the surface of the work piece. So first off, the cutting edge will be on the (somewhat) vertical leading edge of the end of the cutter bit. Exactly how vertical is a function of the desired "lead angle" which may be positive, neutral, or even negative in some cases.
