What do you need to know about bearing installation and preload adjustment

China is a country with a large demand for machine tools and a large consumer, but it is only relatively abundant in the middle and low end categories to meet domestic industrial demand, while the high-end category continues to be less involved. With the development of the industry and the promotion of competition, improving the technical content of products, possessing independent patents and design concepts is a better choice for enterprises to carry out long-term development.

Therefore, in terms of CNC vertical lathe, how to complete the transformation of products from low end to high-end, from primary processing to high-precision manufacturing is the direction that should be considered and efforts should be made in the tide of enterprise transformation. In vertical lathe equipment, the rotary table is one of the central structures that represent the overall performance of the machine tool and complete the machining accuracy of the workpiece. We request that it operate at high speed and accept heavier workpieces at the same time.

With precise operating accuracy and a very high ability to resist overturning torque, the bearing supporting the workbench is the key to completing this important task. Previously, thrust bearings and radial bearings were used in conjunction with most domestic workbenches. This arrangement is complex in structure and requires a large amount of materials. Especially when installing large box parts, the space volume of the entire machine tool is even larger.

The installation and preload adjustment of bearings are also relatively difficult, making it increasingly difficult to ensure alignment, and it is difficult to improve the overall accuracy of the workbench. With the development of science in recent years, high-precision and high-speed machine tools have become popular in the market. It also promotes the machining accuracy of vertical lathe to new heights from time to time. The insertion roller bearing plays a key role in improving the machining accuracy of vertical lathe.
