As an important component of the automobile, the hub bearing unit is gradually updated with the rapid development of the automobile industry. From the first generation to the current third generation, the overall rigidity is better, the load capacity is stronger, and the reliability is stronger, but also brings greater difficulty to the machining process.
The wheel hub bearing unit as a mass-produced part, in order to maintain a shorter delivery cycle in a mass production environment and gain greater market competitiveness, manufacturers need to complete the production of the parts as soon as possible and ensure their quality requirements, so there is an urgent need for a high-performance The cutting tool processes the hard turning process, and the BN-H50 grade of Halnn CBN cutting tool is the best choice. Under high-speed cutting conditions, the BN-H50 grade can perform hard turning stably and reliably, and also is suitable for continuous-intermittent high-precision precision turning.
Characteristics of BN-H50 grade
1. High-purity nano-level CBN particles and imported binder are sintered , which is very suitable for high-speed cutting;
2. Good thermal conductivity and stable chemical properties enable the rapid transfer of cutting heat, reduce thermal deformation of the workpiece, and improve machining accuracy and cutting efficiency;
3. At the same time, Halnn tools provides special coating and wiper treatment to obtain higher tool life and accuracy requirements.
Application of BN-H50 grade
1. Mainly used in the field of hardened steel hard turning
2. Both dry and wet cutting can be used
3. Application: automobile industry, wind power industry, gear industry, bearing industry, machine tool industry, etc.
