Machining grey iron brake disc CBN inserts

• This plate is a disc. At this stage, the common types of brake discs on the market are disc brakes, drum brakes and air brakes. Brake discs are one of the important factors affecting the grade and performance of a car.

  
  

• The material of the brake disc is gray cast iron 250 standard, referred to as HT250, which is the same as the American G3000 standard. Grey cast iron (HT250) not only has good strength, wear resistance and heat resistance, but also has excellent casting properties. More importantly, the brake disc acts as an emergency braking of the car and has good shock absorption performance. Therefore, the material of the brake disc is mostly gray cast iron HT250.

Application Case of Machining Gray Cast Iron Brake Disc

Workpieces: brake disc

Workpiece material: gray cast iron HT250

Inserts model: SBN900 CNMN1207

Cutting parameters: Vc=750m/min, Fr=0.3mm/r, ap=2mm

Processing method: dry cutting

Processing effect: SBN900 is a solid CBN insert to process brake discs, which can realize high-speed cutting, improve processing efficiency, ensure tool life, and reduce tool costs. SBN900 shows excellent wear resistance and long tool life when roughing and finishing gray iron castings. Compared with other CBN tool, its tool life is increased by 40%, the efficiency is increased by 200%, and the cost is effectively reduced.
