CBN tools help CNC lathe efficiently process brake discs The main material of brake disc is the grey cast iron which hardness is about HB170-220 and usually expressed by Brinell hardnessHB. Gray cast iron brake discs are easy to be processed we usually use the conventional carbide cutting tools. But because the brake disc itself profit reducing and the raw material price rising profits are even less. The manufacturing enterprises are searching for the suitable insert material in order to reduce production costs. With the extensive use of CNC lathes the traditional carbide cutting inserts can’t meet the requirements of high-speed cutting when the line speed increased the carbide cutting cutters will be intense wear and frequently replace the cutter the traditional carbide cutting inserts affect the production efficiency and the CNC lathes also can’t play out their own advantages. At present the CBN tools are the most suitable insert for the CNC lathe process brake disc. The reason is as follows: 1. The high hardness and good wear resistance of CBN Inserts is carbide cutting cutter 15-20 times. 2. The CBN Inserts can withstand high-speed cutting and the maximum line speed can reach 1000 m/min 3. It can be used for roughing and finishing the work piece with one CBN insert which will have both high working efficiency and low production costs. 4. CBN Inserts use dry cutting method without adding the cutting fluid it is easy to recover the chip processing and obey the concept of "green manufacturing". 5. CBN inserts can help CNC lathe process efficiently the brake discs. Halnn superhard as the professional cutting tools leader of processing hard materials has good cbn inserts grade for roughing and finishing the gray

cast iron parts such as typical parts brake discs. When roughing the brake disc the process margin is greater than 1mm we recommend choose Halnn superhard CBN Inserts BN-S30 which is solid cbn insert can be processed to complete the margin and ensure the accuracy requirement. When finishing the brake discs we recommend choose Halnn superhard PCBN inserts BN-K20 this grade belongs to the embedded CBN tool which can guarantee the high finish and flatness. If you want to complete rough and finish process with one cutter we recommend to choose Halnn Solid CBN inserts BNK30 the effect will be better. 1. The effect of roughing the brake disc with Halnn superhard Solid CBN insert BN-S30 Machining Materials: Gray Cast iron Workpiece: Brake disc Process Style: Finishing Roughing Process Part: End Face Halnn Grade: BN-S30 Insert Model: CNMN120716-4S Cutting Type: Dry Cutting Cutting Parameters Cutting Depth 2.5mm Feed Rate 0.45mm/r Linear Speed 350m/min Halnn superhard CBN insert BN-S30 not only reduce production costs but also improve production efficiency.
