The methodology of measurement and what is measured when calculating Ra and Rz are quite different. This is critical to understand if you will not be paid for your parts because the Ra you measured is not in fact the Rz surface profile that customer specified.

The development of automatic CNC grinding technology has raised high requirements for its supporting equipment. As one of the supporting technologies, the online automatic grinding wheel dressing technology must meet the needs of modern CNC grinding technology and make it develop towards the direction of high precision, super stability and full self-control.

New materials often cause a domino effect on aerospace processing technology. Environmental problems have forced a change in materials from traditional chromium electroplating to HVOF spraying coating,

Calcined at 800 ~ 850℃, calcined with natural magnesite as raw material, magnesia is a kind of fine powdery gas rigid cementation material.

Grinding process and rolling process can improve the dimensional accuracy of parts and reduce the surface roughness.But there are the following differences.

A gear is a kind of machine element in which teeth are cut around cylindrical or cone shaped surfaces with equal spacing. It is widely used in mechanical transmission and the whole field of machinery.
