1. Halnn Tools BN-S200 Solid PCBN inserts Turning Hardened Steel Wind Power Bearing
Bearing is the key basic component of machinery manufacturing industry and the core component of wind power generator. Due to the harsh environment and inconvenient installation and maintenance, the requirements for the quality and service life of the wind power bearing parts are more stringent.
At the beginning of the wind power bearing, since the hardness of the bearings is subjected to heat treatment after the rough machining, the hardness is high and difficult to be processed, and the grinding is commonly used as the final process step, but with the development of modern cutter industry, the tool material can be turned on the ground for grinding, and the boron nitride blade is developed. Instead of grinding processing, not only improve the processing efficiency, but also reduce the processing cost.
2.Advantages of Halnn Tools CBN Inserts Hard Turning Wind Hardened 42CrMo4 Power Bearings
(1) The processing efficiency is doubled: the machining efficiency is four times higher than that of the same machining accuracy.
(2) Suitable for mass production: CBN tools have high durability, reduce tool change frequency and reduce production costs.
(3) Reducing pollution: Turned iron scraps are more convenient to handle and recycle. At the same time, CBN tools are used to hard-turn bearings without adding cutting fluid to reduce environmental pollution.
The CBN tool cooperates with the vertical lathe hard turning bearing technology, with high processing efficiency and low cost. With the introduction of CBN tools, it is possible to replace the production configuration of several vertical grinding machines with lathes and reduce the construction cost of the plant.
