CBN Inserts for Cast Iron Brake Disc Machining
Workpiece: Brake Disc
User Enterprise: one Auto Parts Manufacturing company in Shandong
Materials: HT250
Hardness: HB180-220
Lathe: Vertical CNC Lathe
This company all used the CBN inserts from BN(China) Tech. for roughing, and the insert model is SNMN1207/CNMN1207. Both acute and obtuse angles of diamond inserts can be used, each nose of the insert can machining 200-300 pieces of workpiece(affected by workpiece’s aging, the working life is different), but the imported carbide inserts can only machining 30-40 pieces by each edge.
The market environment has higher requirements for the brake discs precision and consistency. After update the machining equipments, the brake surface finishing turning has adapted the vertical lathe integrated processing, and the original matching ceramic inserts cannot reach higher requirements.
BN(China) Tech.Co.Ltd optimize the brake surface finishing according to customer’s requirements and improve the working efficiency and quality.
