Circular turning tool for ceramic excircle processing and axial processing method thereof

Abstract

The invention relates to a circular turning tool for ceramic excircle processing and an axial processing method thereof, which belong to the field of the non-traditional processing in machining. The tool mainly comprises a tool handle, a tool body and a tool head which are sequentially and coaxially connected; the tool handle, the tool body and the tool body are hollow round pipes, and the tool body wall is provided with a balance groove; and the tool head comprises tool teeth, through slots formed between every two tool teeth and tooth sockets processed on the inner surface of the tool teeth. The method axially turns the excircle to cylindrical ceramic material through the high-speed rotation of the circular tool; the tool head bottom end surface of the circular tool serves as the main cutting surface removing material, and the inner surface of the tool head of the circular tool serves as an auxiliary cutting surface and grinds the excircle surface of processed work piece; and the rotating speed of the tool is 4000 to 20000r / min, and the rotating speed of the work piece is 0 to 5000r / min. The invention can process the excircle of engineering ceramic material with high efficiency, and has the advantages of simple process, easy operation and lower 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...
