A wheel hub is a cylindrical metal component that supports the inner contour of a tire and is centered on a shaft. Nowadays, cars are increasingly pursuing energy efficiency, safety, and comfort, and the requirements for wheel hubs are also increasing. They must have the advantages of light weight, high manufacturing accuracy, high strength, low inertia resistance, and strong heat dissipation ability.
The precision level of wheel hub components continues to improve, and the M-value tolerance zone continues to shrink, generally reaching level 5 precision, but some have already reached level 4 precision; The material of the wheel hub is generally high-strength medium carbon steel such as C45, which has a high hardness. In addition, some manufacturers have developed specialized alloy grades that are very unsuitable for cutting, which requires higher dimensional accuracy of the cutting tool. On the other hand, it also requires the material and surface treatment of the cutting tool to maintain dimensional stability during the cutting process.
We have been developing and producing wheel hub cutters for many years, and have developed mature technical solutions including materials and their heat treatment, processing technology, surface treatment applications, etc. Our product applications have been recognized by typical customers such as NSK, SKF, Schaeffler, etc.
