Description

Ceramic ring micro ring groove machining tool and machining method Technical Field The invention relates to the technical field of ceramic machining, in particular to a ceramic ring micro-ring groove machining tool and a machining method. Background In the ceramic field of semiconductor parts, ring grooves are quite common in machining characteristics, as compactness and strength of a ceramic ring are greatly improved after sintering, the ceramic ring is generally machined by adopting a grinding or milling mode, and then for ring groove characteristics (diameter is less than 2 mm) with small diameters, machining tools with small diameters can only be selected, so that machining parameters can only be fed slowly to cause low machining efficiency, meanwhile, the abrasion is fast due to small tools, and the risk of bad products caused by cutter breakage is high. In the prior art, grinding and other modes are adopted for processing the micro ring on the product, for example, a processing method of a micro double-ring-belt end face sealing structure is disclosed in Chinese patent document CN 108942089B. The method comprises the steps of carrying out finish turning on the outline of the annular belt, adopting plane grinding to remove micro-cutting lines, adopting different high-precision machining methods aiming at the structural characteristics of each side face of the annular belt in the finish turning process, integrally improving the included angle precision of the cross section of the annular belt, solving the problem that the cross section size is difficult to accurately adjust, eliminating serious machining defects by adjusting the cutter structure and optimizing the cutting parameters, finishing the end face again after one-step forming machining, improving the coplanarity of the end face, and reversely compensating and machining each side face by taking the end face as a reference, so that the two side faces of the annular belt are approximately intersected into a loop line.
