Abstract

The invention provides a machining method of a high-precision superhard-abrasive integral abrasive cutting wheel. The problems that in the prior art, when a grinding process is adopted for machining athin abrasive cutting wheel, efficiency is low, the rate of finished products is low, and operation condition and environment pollution are likely to be caused are solved. The method is characterizedin that the abrasive cutting wheel is a sintered body formed by blending a binding agent and a superhard abrasive material, an abrasive cutting wheel blank is fixed to a carrier through a thermoplastic material, then the carrier is fixed to a workbench of a grinding machine tool, material removing machining is conducted on the blank through an abrasion wheel grinding method, and a finished product with the needed form and location tolerance and size precision is obtained, the abrasion wheel is a common abrasive grinding wheel, by the adoption of the machining method of the high-precision superhard-abrasive integral abrasive cutting wheel, deformation and damage of the abrasive cutting wheel are reduced, the machining yield is increased, and an unexpected technical effect is achieved.

Description

Technical field [0001] The invention relates to the technical field of manufacturing high-precision thin super-hard abrasive abrasive tools, in particular to a high-precision integral cutting grinding wheel processing method. Background technique [0002] The high-precision integral cutting wheel is commonly known as "scribing knife" or soft knife. It is widely used in cutting precision materials such as optical glass, semiconductor materials, and magnetic materials. It has the characteristics of high cutting accuracy and small incisions. The cutting wheel used in this type of grinding wheel generally has a thickness of 0.1mm-0.5mm, and the thinnest is up to 0.05mm. The thickness uniformity of the product is required to be less than or equal to 0.01mm, and the warpage deformation is less than 0.2mmm, so it is called the cutting used for this type of grinding wheel. The grinding wheel is a high-precision super-abrasive monolithic cutting wheel. The material is generally a sintered...
