Aperture turning tool for grinding wheel finish machining and machining method thereof

Abstract

The invention discloses an aperture turning tool for grinding wheel finish machining and a machining method thereof, and relates to the technical field of a turning tool. The cutter comprises a main cutter body, wherein a first chamfering slope is arranged on one surface of the main cutter body, a clamping block is fixedly connected with the position, corresponding to the first chamfering slope, of the main cutter body, internal threads are formed on a bottom surface of the clamping block, blade assemblies are installed between opposite surfaces of the clamping block and the main cutter body,the blade assembly comprises a double-head cutter bar, a through hole is formed on one surface of the double-head cutter bar, and second chamfering slopes are arranged on two sides of the double-headcutter bar. The turning tool is advantaged in that 30-degree included angle design of a diamond composite blade and design of a right-leaning type main cutter body are adopted, a problem of back chipping when a blind hole is machined by a machining person can be effectively solved, an abrasion mode of the tool is changed into post-abrasion through the design, moreover, the cutting force and the turning temperature of the tool bit are effectively reduced through the design, and an edge breakage phenomenon is not likely to happen in the grinding wheel machining process.

Description

technical field [0001] The invention belongs to the technical field of turning tools, and in particular relates to an aperture turning tool used for grinding wheel finishing and a processing method thereof. Background technique [0002] After the grinding wheel has been solidified and roasted, its size, shape and surface mutual position accuracy cannot meet the technical requirements for use, and must be turned and ground. Due to objective technical reasons, most of them at home and abroad use traditional car bowls for turning , during the process of using it, the grinding wheel drives the quenched No. 45 steel thin-walled knife bowl to rotate at a high linear speed (300-400m / min) and performs knife movement to remove the excess of the grinding wheel. The bowl is in contact with high-speed rotation, which causes a lot of dust and noise during processing, and the cutting depth and feed rate are small, so the processing efficiency is low and the overall cost is high. The opera...
