Work-hardening material selected cemented carbide milling cutter Teeth (Mold steel cutting)

Workpiece material:SKD11(HS30)	Parts diagram
Processing machinery: vertical milling machine
Tools：milling cutter 4108R（TX25）
Conditions: rotation speed 130r/min Cutting speed 80m/min Feed rate 0.2mm/r Cutting depth 3mm

Results: when using 8-tooth cemented carbide milling cutter, the swarf attached to the cutting edge wound defect caused by the cemented carbide milling cutter cutting edge. Switch to the 6-tooth cemented carbide milling cutter after the situation becomes very ideal.

When using 8 teeth cemented carbide milling cutter, cutting edge defect, swarf winding phenomenon occurs	When using 6 teeth cemented carbide miller cutter,swarf winding phenomenon not happen again

Summary: The temperature rise of the workpiece material is due to the savings of the heat generated by each cemented carbide milling cutter cutting edge. That is, the heat buildup of at least some of the methods is to use only one cemented carbide milling cutter cutting edge to cut the But then the efficiency will be low. Considering the shape of the workpiece, the cutting area, and cutting conditions, and to increase the number of cemented carbide milling cutter cutting edges and the savings of the heat does not affect the processing conditions, and found that the cemented carbide milling cutter teeth number is 6 teeth ideal.

Cemented carbide milling cutter teeth have a direct impact on the milling efficiency and processing quality cemented carbide milling cutter choice of the number of teeth is not common predetermined cemented carbide milling cutter many teeth and can improve production efficiency, but is limited by the chip space, the machine power and rigidity, the milling of the different diameter knife number of teeth have corresponding provisions. To meet the needs of different users of the same diameter cemented carbide milling cutter number of teeth is generally coarse teeth, teeth, fine-toothed three cemented carbide milling cutter number of teeth to choose from.
