Cemented Carbide Milling Processing Abnormal &Solutions

The cemented carbide milling is a rotary tool for milling, having one or more cutter teeth. Various cemented carbide milling cutter turn work intermittently cut the workpiece margin. Cemented carbide milling is mainly used in the milling machine the machining plane stairs, trench, forming surface and cut the workpiece.

Cemented carbide milling cutter abnormal causes and countermeasures

Situation	Reasons	Solution
Chipping	Large feed	Reduce feed
	Conventional milling (up cutting)	Climb milling (down cutting)
	Cemented Carbide Milling cutting edge is too sharp	The grinding cutting edge - necessary chamfer or fillet
	Vibration	Downward adjustment of spindle speed
	Cemented Carbide Milling cutter prominent too long	Projecting amount of the tool is adjusted to the minimum
	Milling cutter is not firmly clamped	Adjust the fixture accuracy
Wear	Cemented Carbide Milling cutting speed is too high	Reduce the cutting speed
	Feed amount is too small	Increase feed amount
	Conventional milling (up cutting)	Climb milling (down cutting)
	Material hardness is too high	Select special coating milling cutter
Tool breakage	Too large cutting amount	Reduce cutting amount
	Too large cutting force	Lower feed; improve speed
	Cemented Carbide Milling cutter prominent too long	Projecting amount of the tool is adjusted to the minimum
Surface roughness	Vibration	Changing the cutting conditions
	Chip removal is bad	Enhance cutting speed & feed rate or climb milling
	High feed and low cutting speed	Reduce the feed to increase the cutting speed
Processing accuracy	cemented carbide milling cutter is not enough	Replacing the multi-blade cutter
Processing accuracy	Tool deviation	Large blade diameter and prominent amount reduce to minimize
