Why Cutting Tool Blade is Broken
Why Cutting Tool Blade is Broken
Why cutting tool blade is broken sometimes?
1. There is something on the work piece; or the work piece has hole or groove.
Solution:
Check the material content of the work piece, and make sure there are no other objects on the surface, avoiding damaging cutting tool blade.
2. The processing material is not fixed well, so with big cutting tool vibration.
Check the fixing, and re-fasten it.
3. The work piece is too hard may also cause cutting tool blade broken.
4. Router bits quality is not good.
If cnc tool can be under great pressure; and the cutting tool blade is not broken under the condition of shock and vibration in cutting, the cutter materials must be with enough strength and toughness.
5. Cutting tool blade is broken results from wrong installation of downcut cutters careless operation.
6. The cutting tool blade is broken because of too fast speed!
Such like:
(1) Too quick while just start cutting;
(2) Too fast rotation speed or feeding speed;
(3) The cutting depth one time is too deep;
7. The clearance is too much because of loose worktable or router spindle, resulting in the cutting tool blade is damaged.
8. Excessive wear of granite stone tools.
Replace new cutter or cutting tool blade.
9. The cutting liquid is lacking or with wrong adding way, causing sudden changes of cold and heat, thus making cutting tool blade broken.
Measures:
(1) Increase the flow of cutting fluid.
(2) Arrange the location of cutting fluids nozzle reasonably.
(3) Adopt efficient cooling method.
(4) Use dry machining to reduce the heat shock to cutting tool blade.
