Rough Milling Gray Cast Iron Engine block with BN - S300 SNFN120708 Solid CBN Insert from Halnn

1. Halnn Tools BN-S300 Solid CBN Insert Rough Milling Engine block

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 BN-S300 Solid CBN Insert Rough Milling Engine block ?

Halnn Tools PCBN tool processing boron cast iron, boron-copper alloy cast iron, wear-resistant alloy cast iron and other high wear-resistant cast iron cylinder liners, turning-grooving, rough machining, fine cylinder liner inner hole, semi-finished car, fine car The outer circle, the end face and the outer circle of the finished car have long tool life and high processing efficiency. The cutting performance of PCBN tools is much higher than that of coated carbide inserts, which can increase the life by nearly 5 times with greatly improved efficiency.
