Description

technical field [0001] The invention relates to an online trimming device and a trimming method for a copper-based diamond spherical grinding head used in the non-traditional processing field, and is mainly used for online electrolytic precision of the copper-based diamond spherical grinding head in the numerically controlled electrolytic mechanical composite processing. Trimming. Background technique [0002] At present, the processing used in mechanical manufacturing can be divided into traditional mechanical processing and non-traditional processing. [0003] Traditional machining relies on the tool material being harder than the workpiece material, and using mechanical energy to remove excess material on the workpiece, which is generally feasible. However, when the workpiece material becomes harder and the processed surface becomes more and more complex, traditional machining will limit the productivity and affect the processing quality, and sometimes even cannot be pro...
