1. Halnn Tools Full form CBN inserts Hard Turning GCr15 Bearing steel Wind Power Bearings for Hot sale
The simple processing technology of bearing steel is smelting - casting - annealing - roughing - quenching - finishing. The hardness of the workpiece after quenching and tempering is generally above HRC45. For high hardness bearing steel parts, traditional tools (hard alloy tools and ceramic tools) can no longer meet the processing requirements. At present, the tool materials suitable for processing high-hardness bearing steels are ceramic tools and cubic boron nitride tools. The disadvantages of cubic boron nitride cutters are as brittle as ceramic cutters, but cubic boron nitride cutters have certain impact resistance compared to ceramic cutters. Their high hardness, high strength and good wear resistance make them processed. The main tool material for high hardness bearing steel. In particular, the non-metallic binder cubic boron nitride tool developed by Halnn Tools has broken the statement that cubic boron nitride tools can only process workpieces with small feed rate and cannot cut intermittently.
