Problem 1: The feed speed is too fast and the rotation speed is too slow, causing the milling cutter to break.

Solution: Reduce the feed speed or increase the rotation speed

Problem 2: Too much cutting allowance causes milling cutter breakage

Solution: Reduce cutting volume

Problem 3: The tool extends too long and there are too few clamping parts, causing the milling cutter to break.

Solution: Minimize the protruding part and ensure that the clamping times are more than 4 times the handle

Problem 4: The cutting edge is seriously worn

Solution: Change the tool and regrind it, or reduce the cutting speed

Problem 5: The accuracy of the fixture is too poor

Solution: Replace the fixture

Problem 6: Zhuzhou or the clamp is loose

Solution: Adjust the spindle or fixture

Problem 7: The processing surface is complex and there are too many row angles

Solution: adjust cutting parameters, programming method

Problem 8: The workpiece is unstable

Solution: Improve workpiece clamping to ensure workpiece stability

Problem 9: Poor chip removal and severe chip contamination

Solution: Re-select the tool model and change the cooling method
