The spindle unit is the key component of the mechanical transmission system of CNC lathe,so the unit’s assembly accuracy has directly impact on lathe’s machining accuracy while the type selection,measurement and assembly of the unit’s bearings are the most critical factors.A testing and oriented assembly method for spindle bearings of CNC lathe was introduced.After assembly,the bearings have high precision,long service life and stable performance.
