Grinding Machining process of CNC stainless steel parts

CNC precision machining of stainless steel parts is less than 10 m, and the surface roughness Ra is less than 0.1 M. The precision grinding is very small, and it can improve the quality of processing parts.

CNC precision machining grinding is on the working surface of the grinding wheel can be trimmed a large number of high grinding grain micro cutting edge of this characteristic and can be carried out. These high micro cutting edge can be removed from the workpiece on the surface of a number of trace defects and micro shape, size error margin, so the use of these processing method can get a high machining accuracy.

For stainless steel parts processing, first of all the requirements of the machine tool is very high. To have a high accuracy of machine tools, that is, the machine tool grinding wheel spindle rotation accuracy is high, it may be the case of the spindle radial circular error should be less than 0.001mm sliding bearing gap should be between 0.01~0.015.

If three pieces of tile bearing and surface modifying method is first scraping fine bearing, and shaft and bushing of research, research to make scraping disappear so far. After cleaning to adjust to the appeal numerical. Radial feed mechanism sensitivity and repeating precision is very high, the error is preferably less than 0.002mm, so the grinding wheel is easy to form etc. high.

In addition, the stainless steel parts processing of the working table at the speed of the low speed stability requirements in the 10mm/min no creep phenomenon, the reciprocating speed difference is no more than 10%, the work table for smooth, prevent the ends of the vibration ripple. Second, the characteristics of the grinding wheel, such as abrasive, grain size and grinding wheel organization has a great impact on the amount of grinding.

When the grinding wheel, the longitudinal and radial feed rate should be different, the higher the feed rate, the higher the better.
