CNGA120404 CBN Cutting Tool full form Cutting Gray iron Brake Disc From Halnn Tools

Halnn Tools Solid CBN Tips Cutting Gray iron Brake Disc

1. Halnn Tools Solid CBN indexable Insert Finishing Cast iron Brake Rotor From Halnn Tools

With the development of the automobile industry, the brake disc industry also

develop rapidly because it is one of the most important parts in brake system. And brake disc often produce with large quantity. They use CNC Lathe, especially for big manufacturers. They need high efficiency in the process. But with traditional carbide insert, it has low cutting speed, can’t satisfy the manufacturer. CBN Inserts can be used for machining cast iron parts with high speed, so it became the best choice for these brake disc manufacturers.

2. Why we Choose Halnn Tools Solid CBN indexable Insert Finishing Cast iron Brake Rotor From Halnn Tools

Brake disc has low hardness, traditional cutting tools can machine brake disc, but why do the manufacturers also choose CBN inserts which costs higher than traditional cutting tools?

CBN insert has high harndess and excellent wear resistance, and can realize high speed cutting with 500~2000m/min, so CBN insert is the right tool for machining brake dice with CNC lathe, it also can satisfy the high surface quality and the parallelism.
