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
Tool deviation Large blade diameter and prominent amount reduce to minimize
