High Cost Performance RCMN full form CBN Turning Insert Finishing Gray Cast iron Brake Disc

High Cost Performance RCMN full form CBN Turning Insert Finishing Gray Cast iron Brake Disc

1. Halnn Tools RCMN full form CBN Turning Insert Finishing Gray Cast iron Brake Disc

According to statistics, in the cost of machine manufacturing industry, the cutting fluid

has occupied 15%, and the costs on cutting tools only have 3%~5%. So the new technology of dry cutting will become one new technology. It not only can lower the total costs, but also can reduce the environment pollution. In the process, the most important is cutting tool material.,In order to achieve high cutting speed and dry cutting type, the cutting tools materials need have High temperature red hardness, stability and low Coefficient of friction. The materials can be only cubic boron nitride in nowadays.

2. Why we Choose Halnn Tools full form CBN Turning Insert Finishing Gray 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 know that 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.
