- Abstract
As the core components of machine tool spindles, the bearings have an important impact on machining accuracy and efficiency of machine tools. However, at present, the angular contact ball bearings for high - end machine tool spindles still rely on imports, and there is a lack of performance comparison data and application cases of the bearings at home and abroad, affecting the promotion of domestic bearings. Combined with user requirements and relevant standards, the application of grease - lubricated angular contact ball bearings 7014 in machine tool spindles at home and abroad is compared. A test scheme is designed according to assemblability, accuracy, static stiffness, temperature rise, vibration resistance and reliability indexes that t users are most concerned about. The bearing performance test, spindle bench test and machine tool cutting test after bearing installation are carried out. The comparative analysis shows that the comprehensive performance of domestic bearings reaches or approaches that of foreign bearings.
