The spindle bearing oil has the following functions: outstanding smoothness, oxidation resistance, rust resistance, and suitable viscosity and viscosity temperature. In the meantime, smoothness is the first performance; in order to maintain the relationship between the spindle and the bearing contact surface It has a uniform oil film; it does not damage the oil film when the spindle starts or stops the impact load; insisting on outstanding smooth function plays the role of reducing conflict and conflict heat and ensuring machining accuracy; it is necessary to have outstanding smooth function and resistance Oxidation is the first of its kind; when the machine tool spindle is selected for the smoothing method; the spindle bearing oil is required for long-term use without deformation, so it is required to have excellent oxidation resistance. The rust resistance is inevitable because the oil is in the smooth process of the spindle. It will be mixed with air in the air or machine coolant; therefore, the oil needs excellent rust resistance, and finally its viscosity and viscosity are avoided when the spindle operating temperature and ambient temperature change greatly; the viscosity change is too large and affects Its smooth function.
