Abstract

The invention relates to a device and a method for dressing grinding wheels, in particular to a device and a method for dressing large-abrasive-grain diamond grinding wheels. The device and the method for dressing large-abrasive-grain diamond grinding wheels aims to solve the problem that large-abrasive-grain diamond grinding wheels cannot be directly used for precision grinding due to large radial rotation errors and are bound to be replaced by fine-abrasive-grain grinding wheels for subsequent precision grinding. The device comprises two disks, two clamps, two couplings, two speed reducer and two motors, the two disks are arranged on two sides of the axis of a grinding wheel, the axis of each disk is perpendicular to the axis of the grinding wheel, the end face of each disk contacts with a grinding face of the grinding wheel, each disk is mounted on one clamp, each clamp is connected with one coupling, each coupling is connected with an output end of one speed reducer, and an input end of each speed reducer is connected with an output end of one motor. The method includes the steps: firstly, mounting; and secondly, detecting radial rotation errors of the large-abrasive-grain diamond grinding wheels, and completing dressing until requirements are met. The device and the method for dressing grinding wheels are used for precision dressing of dressing grinding wheels.

Description

technical field [0001] The invention relates to a grinding wheel dressing device and method, in particular to a precision dressing device and method for large abrasive diamond grinding wheels. Background technique [0002] At present, in the processing of hard and brittle materials such as optical glass, the rough machining method with high processing efficiency is mostly used first, then the semi-finishing method with better processing surface is used, and finally the fine-grained or granular grinding wheel is used for precision machining. / Ultra-precision machining. In this way, 2 to 3 processes are used for continuous processing, and different grinding wheels must be replaced in each process, resulting in high processing costs and low overall grinding efficiency. In addition, the fine-grained / micro-grained grinding wheel has a small space for chips, which will generate more The particles fall off, which cannot meet the requirements of machining accuracy, and the irregula...
