Grinding machnie used for processing linear guide rail

Abstract

A grinder for machining straight-line guide track is composed of a main body, a bench on the main body, a fixture on the bench, a gantry above the main body and consisting of two vertical columns and transverse beams, two servo motors at both sides of front transverse beam, feeding carriage driven by leading screw, electric mainshafts on said carriage, and lift adhesive discs arranged to lower end of each electric mainshafts. It has high machining precision.

Problems solved by technology

[0002] Due to the long length of the linear guide, it is easily deformed

At present, the rolling linear guide rails are all clamped and ground once on the grinding machine. The grinding wheels used in one grinding are a pair of medium-grained grinding wheels. The surface is rough and does not meet the requirements, which affects the movement accuracy of the guide rail. If the grinding wheel with fine grain size is selected, the grinding wheel will have poor grinding ability, abrasive grains will fall off, and the processed surface is prone to burns, grinding cracks and other problems, and the production efficiency is low. The cost rises, etc., so a pair of medium-grained grinding wheels are generally used

The surface roughness after processing with a medium-grained grinding wheel is also high, generally between Ra 1.25-Ra 1. The roughness is difficult to meet the design requirements, which affects the accuracy of the guide rail. The linear guide rail will crawl and roll poorly when rolling. affect product quality
