Small grinding wheel creep feed grinding processing method capable of adjusting cutting angle for engineering ceramic

Abstract

The invention relates to a small grinding wheel creep feed grinding processing method capable of adjusting a cutting angle for processing external cylindrical surfaces or conical surfaces and other shaped surfaces of engineering ceramic and other hard and brittle materials, belonging to an unconventional processing method in the field of traditional mechanical processing. The processing method is characterized in that: cylindrical engineering ceramic and other hard and brittle materials are subjected to creep feed grinding processing by high-speed rotation of a diamond small grinding wheel to form external cylindrical surfaces or conical surfaces; when the cutting angle is smaller than 45 degrees, the end surface of the small grinding wheel is used as a main cutting surface to remove the materials, and the circumference surface of the small grinding wheel is used as an auxiliary cutting surface to finish the external circle surface of the processed piece; when the cutting angle is larger than 45 degrees and smaller than 90 degrees, the circumference surface of the small grinding wheel is used as the main cutting surface to remove the materials, and the end surface of the small grinding wheel is used as an auxiliary cutting surface to finish the external circle surface of the processed piece; and the rotation speed of the grinding wheel is 6000-20000 r / min and the rotation speed of the workpiece is 0-5000 r / min. By adopting the processing method, external cylindrical surfaces or conical surfaces of the engineering ceramic and other hard and brittle materials can be processes at low cost and high efficiency; and the structure is simple and the operation is easy.

Description

technical field [0001] The invention belongs to an unconventional processing method in the field of traditional mechanical processing, in particular to a slow-feed grinding processing method with adjustable cutting angle for hard and brittle materials such as cylindrical engineering ceramics. Background technique [0002] At present, the most common method of processing the outer cylindrical surface (or conical surface) of hard and brittle materials such as engineering ceramics is still the traditional diamond grinding wheel grinding, that is, reciprocating grinding with parallel grinding wheels. In the processing process of this method, the diamond grinding wheel generally needs to be used with a large grinding wheel with a diameter of 400-500mm or more, and the thickness of the diamond layer is only a few millimeters, and the wear is very fast during processing, resulting in very expensive processing costs. The processing cost accounts for 70% to 90% of the total cost, and...
