The processing technology of auto parts is high and the process is complex. The processing methods mainly include milling, drilling, boring and so on. In order to achieve high-quality processing level, cutting tools are required to have the characteristics of high speed, high precision and high efficiency. Therefore, the importance of cutting tools is self-evident in the automobile, parts industry and upstream and downstream processing industry chain.

Rough milling of turbocharger shell surface is one of the high cost parts in all machining processes. Shangao's double-sided King milling cutter is very suitable for this working condition. The high-speed steel locating pin on the cutter body is matched with the fine grinding locating groove on the blade, and the runout can be controlled within 10-20 μ M or even lower.

In view of the weak overall rigidity of the turbocharger shell during machining, the blade has been specially improved, and the unique groove type and fillet are adopted, which can not only ensure the lightness of cutting, but also ensure the strength of the tool. The processing is very strict. The processing procedures include feeding, discharging, etc.

There are specific requirements for size and accuracy, such as 1mm plus or minus microns. If the size is wrong too much, it will become waste products. At this time, it is equivalent to reprocessing, which is time-consuming and laborious. Sometimes, the whole processing material will be scrapped, which increases the cost. At the same time, the parts must not be used.
