Abstract
In machine tool, the accuracy of slideway is one of the important subjects as well as the stability of the rotation of main spindle.
Therefore, the slideways are protected from wear by means of lubricating oil and dust wiper, etc. In actual operations, however, accidents are apt to happen caused by the wear of slideways.
The actual lubricating conditions were analyzed on machine tool, especially on lathe, and the actual value of ZV/P indicating the lubricating conditions was obtained; in addition, critical value of ZV/P indicating the boundary point between fluid and boundary lubricating zones was also obtained.
Then, the experiments on the wear test of slideways with lathe were conducted under the actual lubricating conditions. The degree of wear of slideways was traced by checking the surface roughness with Talysurf roughness tester.
In this paper, there are described on the actual value of ZV/P on machine tool slideways, critical value of ZV/P, and the effects of lubricating conditions and the wiper on the wear of slideways are described.
