Characteristics and application of spindle bearing oil

发表时间:2018-04-28 14:21

Spindle bearing oil is a precision machine tool spindle bearing special lubricating oil and similar equipment, it to ensure the accuracy of the spindle work and use of performance, prolong its service life plays a very important role, is also called the bearing oil.





Its main performance:



1. Suitable viscosity and good viscosity-temperature characteristics



To make the machine tool spindle temperature is not too high and make the machine tool thermal deformation, affect the machining accuracy or make poor lubrication bearing, should according to the structure of the spindle bearing, speed and bearing clearance to choose appropriate temperature of lubricating oil and requires its good viscosity-temperature characteristics, prevent for spindle working temperature and environmental temperature change is big, the change of the viscosity is too large and influence its lubrication performance.





2. Good lubricity



To keep between shaft and bearing contact surface have a uniform oil film, and in the main shaft impact load of oil film start or stop the movement also not dent, keep good lubrication performance plays a reduce friction and friction heat, lowering the temperature rise of the main shaft, ensure the machining accuracy requirements has good lubrication performance.





3. Good oxidation resistance



When the machine tool spindle is lubricated by circulation, the spindle bearing oil should be used for a long time without deterioration.





4. Good rust resistance



Since oil products will inevitably be mixed with condensed water or machine tool coolant in the air during the work of spindle lubrication system, it is required that oil products have good rust resistance.
