CNC Single Point Keyway Broaching Size Ranges 1/8 .126 to 1/2 .502 Inch, 4mm-12mm Metric ID 753-

For CNC lathe: mount tool directly into the turret on centerline while a setscrew-locking holder will lock into place and position.

For CNC vertical machining center: a collet will hold the tool shank and provide timing orientation.

With the spindle locked, the broach can be brought in line with pre-prepared bore diameter and chamfer lead of the part to start

broaching the keyway at a speed of 10” – 30” in/min and an in-feed of .003” -.005” depth per pass,

using a flood coolant for lubrication during the cut.

Once the initial process is achieved, speeds can be increased to 50 - 80 IPM.

The in-feeding cycle is repeated until

the desired depth of the keyway is achieved. Chips can be removed from the bottom of the hole in a couple of ways:

In a blind hole bore, remove the chips by either:

Prior trepanning the bottom of the keyway area and allow chips to fall away.

Or pre-drill a hole from the outside to the inside of the part at the bottom of the keyway location.

With a through hole, you can broach right through, but do not disengage with the part, and simply deburr the keyway upon completion.
