[0002] As an important method for in-depth study of the grinding mechanism, the single abrasive grain scratch test has been widely used in recent years. The high-speed continuous scratch test machine for single abrasive grain can collect scratches stably under high speed conditions. In order to ensure high test accuracy, the high-speed continuous scratch testing machine has higher requirements on the accuracy of each part, and the parallelism between the feed axis and the scratch plate is the decisive factor affecting the change of scratch depth during the test. If the direction of the feed axis is not parallel to the plane of rotation of the scratch tester, the scratch depth of a single abrasive particle will change during the feeding of the tool head along the direction of the scratch tester's feed axis, which will seriously affect the test accuracy.
