Brake Drum Grey Cast Iron Rough Interrrupt Turning By Solid CBN Cutter Inserts

1. Brake drum basic information.

As the main components of the large automobile industry, the brake drum determines its driving safety, so the quality of the brake drum is particularly important. As the friction coupler of the drum brake, the brake drum should have the highest and stable friction coefficient as well as the appropriate wear resistance, heat resistance and heat dissipation in addition to the strength and rigidity required as the member. As the main application materials, gray cast iron is often used as the heat capacity.

3. Why choose a CBN inserts that is more expensive than traditional carbide tools?

(1) Gray cast iron material is mainly used in machine tools, automobiles and other industries. Most of the parts are mass-produced, which requires high production efficiency. Although traditional carbide tools can also process gray cast iron, the processing efficiency is low and only suitable for small batch production. , or occasionally processing gray cast iron parts.

(2)Nowadays, enterprises that produce high-volume gray cast iron parts mainly use CNC lathe processing. Many people know that traditional tools can't cut at high speed. When the maximum line speed (350m/min) is exceeded, severe wear will occur, which will affect production efficiency and the surface quality of the workpiece.

(3) CBN inserts have high hardness and good wear resistance. The precision gray cast iron can achieve a line speed of 1000m/min, so it is suitable for mass production of gray cast iron parts with CNC lathes. And can guarantee high requirements such as smoothness and flatness.
