BN - K20 DNGA CBN Turning Insert Semi-Finishing Cast iron Brake Disc with better wear resistance

1. Halnn Tools CBN Turning Insert Semi-Finishing Cast iron Brake Disc

Brake Disc as one of the main parts in the brake system, which will keep the safety. With the development of the manufacturing industry, the cars manufacturers required higher than before on the brake disc surface quality and the dimension, ect. All will require higher on the cutting tools for machining brake disc.

2. Why we Choose Halnn Tools CBN Turning Insert Semi-Finishing Cast iron Brake Disc ?

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?

(1) Brake Disc belong to Mass production, it requires high on the production efficiency, traditional cutting tools,such as carbide insert can machine brake disc, but the process efficiency is low. It only suit for small production.

(2) Nowadays most mass production brake disc enterprise, they use CNC Lathe, and many manufacturer knowthat traditional cutting tools can be used for high speed cutting, when the cutting speed is above 350m/min, the insert will wear rapidly which will affect the production efficiency and the workpiece surface quality.

(3) 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.
