Common Tool Breakage Issues
Possible Cause: Remedy
•Deflection- cutting edge too long: Select a tool with cutting edge not more than ¼” longer than material thickness.
•Bad or worn collets: Check tool shank for evidence of chatter marks. When visible, replace collets.
•Over-torquing: If tool breaks in the shank area, tightening the collet nut to incorrect torque can cause tool breakage. Invest in a setup-fixture and torque wrench.
•Overheating: If signs of heat buildup are in the tool flute, check chip load and adjust feed/speed.
•Part Movement: Improve vacuum hold-down.
•Too much pressure on the tool tip: For rebates, grooves, and slots, use the shortest length to avoid tool breakage.
•Tool slippage in the collet: Replace static collet nut with a bearing nut.
