Small hole reaming method on ceramic part and ceramic part thereof

Abstract

The invention applies to the field of processing of ceramic parts, and provides a method for expanding pores in a ceramic part and the ceramic part manufactured by the same method. The method comprises the following steps: arranging a dry type sand-blasting machine, a jig, and a motor which drives the jig to rotate; fixing the ceramic part on the jig, and aligning each pore in the ceramic part to a sand-blasting head of the dry type sand-blasting machine; positioning silicon carbide into the dry type sand-blasting machine; starting the motor, and starting the dry type sand-blasting machine to spray the silicon carbide at a high speed to a position to be treated on the ceramic part, so as to expand the pores in the ceramic part. According to the method, the silicon carbide sand is sprayed at high speed to the position to be treated on the ceramic part through the dry type sand-blasting machine, the position to be treated on the ceramic part is grinded by the high-speed impacting of the sand flow formed by the silicon carbide sand, thus redundant remains on the position to be treated on the ceramic part can be removed, and as a result, the pores can be expanded.

Description

technical field [0001] The invention belongs to the field of ceramic parts processing, in particular to a method for expanding small holes on ceramic parts and ceramic parts obtained by using the method. Background technique [0002] Compared with metal materials, ceramics have completely different properties, that is, ceramics have high shear stress resistance, low tensile stress resistance, and relatively large elastic modulus, so it is difficult to use the usual metal cutting methods to process them. Ceramics are processed. In addition, most ceramics are insulated, and it is generally not suitable to use electrical machining methods such as electric sparks and wire cutting, which greatly restricts the processing methods of ceramic materials. This has caused great obstacles to the promotion of industrial ceramic materials, especially with the development of industrial ceramic materials in the direction of high strength, high toughness, and high density, making processing ...
