Automatic CNC machine tool spindle temperature is too high to prevent deformation

Fully automatic CNC machine tools in the work, because the working spindle temperature for a long time will also increase, which will lead to thermal deformation of fully automatic CNC machine tools. At the same time will affect the processing accuracy or make the bearing smooth bad, should be based on the spindle bearing layout, speed and bearing voids and so on to choose the appropriate temperature of the smooth oil and demand it has good viscosity-temperature characteristics, to avoid the CNC machine tool spindle temperature rise, viscosity change is too large and affect its smooth function.

First, it has better smoothness

In order to make the spindle and bearing contact surface between adhere to a uniform oil film, and in the spindle start or stop movement impact load when the oil film is not damaged, adhere to the outstanding smooth function plays the role of cutting conflict and conflict heat, reduce the spindle temperature rise, to ensure the processing accuracy, the need for outstanding smooth function.

Second, has the good oxidation resistance

Machine tool spindle in the selection of circular smooth method, the need for long-term use of spindle bearing oil does not degenerate, so the demand has excellent oxidation resistance.
