Overview

With the continuous improvement of process equipment technology, a large number of gear grinding machines have appeared in the gear industry. Grinding burns are an inevitable problem. Some manufacturers still have problems after long-term debugging, which has a huge impact on the economy. threat. The grinding wheel will burn during grinding. Generally speaking, this is affected by the heat treatment. What is the specific reason for this phenomenon?

1. During decarburization heat treatment, improper surface or environmental protection will cause surface oxidation, which will produce a thin decarburization layer on the workpiece. This soft decarburization layer will cause the grinding wheel to be overloaded or overheated, resulting in surface damage. fire.

2. The carbon concentration of the infiltrating layer is too high, and it is easy to form network carbides or excessive free carbides in the infiltrating layer structure. Because this substance is extremely hard. During grinding, localized overheating tendencies and surface tempering may occur. Too high a carburizing concentration will cause excessive retained austenite on the surface of the workpiece, resulting in burns and cracks. Therefore, the increase of the surface carbon concentration reduces the grinding performance. Generally, the surface carbon concentration should be controlled within the range of 0.75%-0.95%.

3. Carbide distribution and shape Carbide distribution should be uniform, and the average particle size diameter should not be greater than 1 μm;

4. The heat treatment deformation should be reduced as much as possible, which can reduce the grinding allowance. If the heat treatment deformation is too large, if the grinding operation does not start at the places where the radial runout of the workpiece is large, the grinding allowance removed at these points with each grinding will be abnormal, resulting in burns and cracks .
