Abstract
Description
technical field
[0001] The present invention relates to a non-API thread ring gauge electroplating superabrasive forming grinding wheel base structure design method, in particular to a non-API threading ring gauge electroplating superabrasive grinding wheel structure design and forming grinding process, which belongs to metal material grinding technology field. Background technique
[0002] Non-API thread ring gauge is a special measuring tool specially used to comprehensively inspect the processing quality of non-API threaded joints (external threads) of oil well pipes. It has high requirements on the wear resistance, dimensional stability and processing accuracy of the workpiece. Temperature control, avoiding grinding burns, and obtaining high processing efficiency have high demands. The material of the parts is 9Mn2V, which contains high Mn elements and a small amount of V elements. After heat treatment, high hardness (HRC60~63) and good wear resistance can be obtained. ...
