As a core component of vehicle braking systems, the machining precision of brake discs is directly related to driving safety. The industry has set stringent standards for it: the circumferential thickness difference between the two braking surfaces should be ≤ 0.009mm, the parallelism should be ≤ 0.04mm, the circular run - out error should be ≤ 0.025mm, and the surface roughness should reach Ra1.6 or above.

With the automation upgrade of the automotive manufacturing industry, traditional carbide tools tend to have problems such as low efficiency, frequent tool changes, and unstable precision, making it difficult to meet the requirements of mass production.

LINKUT has specifically launched a series of Solid Cubic Boron Nitride (Solid CBN) and Polycrystalline Cubic Boron Nitride (PCBN) inserts to precisely address these machining pain points.

The products have three core advantages:

First, they are high - speed and efficient. They can withstand high - temperature and high - speed cutting. The maximum linear speed for rough machining is 1200m/min, and for finish machining, it reaches 2000m/min. They are suitable for the double - tool synchronous machining process, doubling the efficiency.

Second, they have an ultra - long lifespan. Their wear resistance far exceeds that of traditional tools, and their service life is more than ten times longer, greatly reducing tool - changing and procurement costs.

Third, they have stable precision. The cutting edges have excellent retention. Long - term processing can stably maintain a roughness of Ra1.6, and can even achieve a mirror - like finish of Ra0.8.

LINKUT focuses on the R & D and innovation of super - hard tools. With its core technology, it provides automotive manufacturing enterprises with efficient and stable cutting solutions, helping to improve quality and increase efficiency.
