The vehicle’s wheels are connected to the half shaft through wheel hub bearings. As the wheels rotate and brake, the hub bearings must withstand significant loads and impact forces. With the combined support of the inner ring, outer ring, and ball cage, the bearings can effectively distribute and bear these loads, ensuring stable wheel operation. Hub bearings must operate under complex conditions of high speed and heavy load, requiring materials with high hardness, excellent wear resistance, fatigue resistance, and corrosion resistance.
In the machining of wheel hub bearings, customers typically face the following challenges:
* The material has high hardness and strict precision requirements, demanding excellent wear resistance from the cutting tools — requirements that standard tools often struggle to meet.
* Hard turning must ensure both surface quality and dimensional accuracy while leaving a uniform and appropriate machining allowance for subsequent finish grinding.
* The high difficulty of machining high-strength materials leads to elevated processing costs and low efficiency.
Worldia’s customized PCBN turning solution significantly extends tool life, reduces the frequency of tool changes, improves machining efficiency, and effectively lowers production costs.
