Annular Turning Tool for Ceramic Cylindrical Machining and Axial Machining Method

Abstract

The invention relates to an annular turning tool used for ceramic outer circle processing and an axial processing method thereof, belonging to the non-traditional processing field in mechanical processing. The cutter is mainly composed of a handle, a cutter body and a cutter head connected coaxially in sequence, and the handle, the cutter body and the cutter head are all hollow tubes, and a balance groove is opened on the wall of the cutter body; It consists of cutter teeth, a through groove formed between two cutter teeth and a tooth groove processed on the inner surface of the cutter teeth. The method is to use the annular cutter to rotate at high speed to axially turn the outer circle of the cylindrical ceramic material; use the bottom end surface of the cutter head of the annular cutter as the main cutting surface to remove material, and use the inner surface of the annular cutter cutter as the The auxiliary cutting surface is used for grinding the outer surface of the workpiece; the tool speed is 4000-20000r / min, and the workpiece speed is 0-5000r / min. The invention can realize high-efficiency processing of the outer circle of engineering ceramic materials, and has simple structure, easy operation and low cost.

Description

technical field [0001] The invention belongs to the technical field of non-traditional processing in mechanical processing, and in particular relates to an annular axial turning tool and a processing method for ceramic outer circle processing. Background technique [0002] At present, the processing method of the outer circle of engineering ceramics mainly adopts traditional diamond grinding wheel grinding, which has low efficiency and high cost. Many scholars are committed to developing new high-efficiency, low-cost, low-damage ceramic cylindrical machining methods. After decades of development, on the basis of ordinary grinding processing technology, special processing and composite processing such as high-speed (ultra-high-speed) grinding, ELID grinding, laser heating assisted turning, ultrasonic vibration turning, abrasive water jet turning, etc. have been developed. technology. [0003] High-speed (ultra-high-speed) grinding and ELID grinding are still based on grindi...
