Keys to Using
Razorform Broaching Tools

1. No Ramping, Slanting or Angled cuts. Razorform is designed for a straight-ahead cut. Improper use may result in the insert pulling out of the pocket or the tool crashing.
2. Check the tool holder with an indicator to ensure a rigid set-up throughout the cutting stroke.
3. If going into a blind or through hole there must be coolant for chip evacuation. If going into a blind hole there MUST be a 1/8-1/4 inch relief.
4. Carbide needs to be run very fast. We recommend 300-450 IPM (depending on material) on the rough cut and 150 IPM on the finish cut or 150%-175% power. Start the cut by taking .0015 per pass. If it handles that OK then bump it up. Cycle times won't be hurt by not taking very much off because of how fast your cutting.
5. Program the tool to drop down enough to clear the insert of the part and the keyway on the retraction. The insert must not rub at any point on the withdrawal or the corners may chip.
6. Only for clients running months long production, change setscrews. In rare cases, worn out by friction, setscrews will "flatten" and not grip causing insert "pop-up" and crashes.
7. You must have a locking spindle to operate Razorform Broaching Tools. Check the locking spindle with an indicator to ensure zero movement.
8. After use, additional hand-honing may extend insert life.
