The performance and characteristics of main shaft bearing oil

Oil is a precision machine tool spindle bearings and similar spindle bearing special lubricants, it has to ensure the accuracy of the composite work spindle bearings and performance, extending its life plays a very important role, also known as bearing oil.

Its main properties are:

1, a suitable viscosity and good viscosity-temperature characteristics

For the spindle temperature will not be too high and the machine thermal variations, influence or make the sliding bearing precision bearing lubrication bad, it should be based on the structure of the spindle bearings, speed and bearing clearance and other selected suitable temperature lubricants and requires that they have good viscosity temperature characteristics, and prevent the spindle temperature and ambient temperature change is large, the change in viscosity is too large to affect its lubricating properties.

2, good lubricity

To make the contact surface between the shaft and the bearing to maintain a uniform film, but also in the spindle start or stop motion film is not caused by an impact load damage and maintain good lubricating properties to reduce friction and friction heat plays, reduce the spindle temperature, guarantee the role of precision, requires a good lubricating properties.

3, good resistance to oxidation

Spindle when the cyclical lubrication, long-term use requires spindle bearing oil without deterioration so requires a good oxidation resistance.

4, good anti-rust

Since the spindle lubricating oil during operation of the system will inevitably mixed with the air condensing water or machine coolant, thus requiring oil has good corrosion resistance.
