In high-speed machining, the thermal characteristics of the electric spindle are a major factor affecting the machining accuracy, and directly affect the increase of the rotational speed of the electric spindle. In the temperature rise of the electric spindle unit, the bearing temperature rise is an... read more
Quasi-dry machining is a new type of machining that replaces traditional lubrication cooling with a small amount of lubrication. It has been applied in some enterprises. Under the condition of dry cutting, the cutting process is different from the traditional wet cutting. For example, the feed speed... read more
