Embodiment Construction

[0009] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0010] Referring to the accompanying drawings, the bolt-fastened flat grinding wheel is code-named 36-600×80×305WA / F46N6V-35m / s, and its working part 1 is a vitrified bonded grinding wheel with a thickness of 60mm; the mounting part 2 is embedded with a metal nut 4 Resin bond grinding wheel, thickness 20mm. The peripheral portion of the outer end surface of the working part 1 is an arc-shaped profile 3 with an arc radius R=180mm.

[0011] The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.

Abstract

The invention relates to a bonded abrasive tool for machining, in particular to a bolt-fastened grinding wheel which comprises a working part and a mounting part, and metal nuts are embedded in the mounting part. The circumference portion of the outer end face of the working part is an arc-shaped molded surface, and the arc radius in the axial section of the arc-shaped molded surface is 1-5 times the thickness of the working part. The bolt-fastened grinding wheel is used for plane grinding on workpieces, an end face grinding mode is adopted, and when the unevenness of the surfaces of the workpieces is obvious, due to the arc-shaped molded surface of the end face of the grinding wheel, impact of protruding portions of the workpiece to the grinding wheel can be greatly reduced; the grinding wheel edge breakage phenomenon is avoided, the service life of the grinding wheel is prolonged, and the grinding effect of the grinding wheel is improved.

Description

technical field [0001] The invention relates to a bonded abrasive tool for machining, in particular to a bolt-fastened grinding wheel for end face grinding. Background technique [0002] Bolted grinding wheels, especially resin bonded bolted parallel grinding wheels, are widely used in machining. According to the standard JB / T7983-2001 "Bolt Fastened Flat Grinding Wheel", the working surface of the grinding wheel is flat, and the grinding method is end grinding, that is, grinding with a flat surface during work. When the surface roughness of the workpiece to be ground is poor or the unevenness is obvious, when the grinding wheel moves along the surface of the workpiece under high-speed rotation, the raised parts on the surface of the workpiece will form a large impact on the circumference of the grinding wheel, often causing The edge chipping of the grinding wheel will affect the service life and grinding effect of the grinding wheel.
