导轨磨床是精加工机床,加工精度除与机床本身的精度有关外,与机床的润滑油性能也有密切关系。导轨磨工作台运动速度较低,又经常处于启动、停止、反向状态。当润滑油膜适度时,才能保证工作台在导轨上正常平稳运动。如果油膜破裂,导轨面上会产生干磨擦,导致工作台爬行,并加快导轨面的磨损。而当润滑油膜过厚时,则工作台将产生飘浮。这些导轨磨工作台的不正常运动现象,都要影响到其工作性能,降低加工精度。所以,正确选择导轨磨床
Rail grinding machine is a finishing machine, machining accuracy in addition to the accuracy of the machine itself, but also with the performance of the lubricating oil machine are also closely related. Guide rail grinding table movement speed is low, and often in the start, stop, reverse state. When the lubricating oil film is moderate, can the worktable ensure the normal smooth movement on the guide rail. If the oil film ruptures, the rail surface will produce dry friction, leading to table creeping, and to speed up the rail surface wear. When the lubricating oil film is too thick, then the workbench will have a floating. Abnormal movement of these rail grinding table, have to affect their performance, reduce processing accuracy. Therefore, the correct choice of rail grinder
