Cutting a slot in carbide
I need to cut a 1/8" by 1/8" +.020"/-0 slot through one side of a 3/4" x
3/4" x 1/4" square carbide insert. Do I need to send this out to an EDM shop? |

Cutting a slot in carbide
Just did this with a diamond wheel mounted in our gearhead drill press
(special arbor). Removed a .060" x .060" corner in C-2. Used .010" side steps at full depth. Didn't take long. HTH Doug |

Cutting a slot in carbide
It could also be ground with a diamond cut-off wheel.
Check with a commercial / industrial tool & cutter grinder. You can even do it yourself in a milling machine (or possibly lathe). You turn up a copper disk and tap in diamond abrasive into the disk's circumference. Then use as grinding wheel to cut slot. Wolfgang |
