Linear guide rail is used in high-precision or high-speed linear reciprocating motion occasions, and can bear a certain torque, and can realize high-precision linear motion under high load. With the arrival of the Industry 4.0 era, the market demand for linear guide rail will also increase rapidly, and more and more linear guide rails are used in various machines. The application of linear guide rail in machine tool can affect the positioning of workpiece and the joint degree of surface. In the system, the reaction of mechanical components may have a great influence on the reversal error. Then, what are the application advantages of linear guide rail in machine tools?
1. The positioning accuracy is high. Because the friction mode of the linear guide rail is ball rolling friction, not only is the friction coefficient reduced to 1/50 of that of sliding guide, but also the gap between dynamic friction and static friction is reduced, so when the machine tool is running, there will be no slippage and the positioning accuracy can reach micron level.
2. The wear is small and the service life is long. The wear of the rolling guide of the linear guide rail is very small, so the accuracy of the machine can be maintained for a long time. Using high-hardness carbon steel material can improve the wear resistance of the guide rail and ensure the minimum wear and long service life.
3. It can move at a high speed with low horsepower, and the moving friction of the linear guide rail is very small, so the bed can run with only a small amount of power. Especially when the machine tool runs back and forth frequently, it can obviously reduce the power loss of the machine, thus reducing the production cost of enterprises. Moreover, the high carbon steel has less heat generated by its friction, which is suitable for high-speed operation.
These are the application advantages of some linear guides in machine tools. With the continuous expansion of China's electric power industry, data communication industry, urban rail transit industry, automobile industry and shipbuilding industry, the demand for linear guides will also increase rapidly, and the linear guide industry has great development potential in the future.
