What Are the Advantages of Ground Linear Racks?

Rack grinding refers to grinding the tooth surface and sides of the rack after heat treatment to remove burrs and deformation to improve the accuracy of the linear rack.

Improved Accuracy

The rack is heat treated and the tooth surface is ground on all four sides, with high precision and long service life. The grinding process can achieve higher tooth shape and pitch accuracy, ensuring that the geometry of the rack meets the design requirements, thereby improving the overall accuracy of the transmission system.
After grinding, the gap between the teeth of the linear rack is smaller, which can effectively reduce the transmission error and improve the positioning accuracy.

Smooth Operation

The linear rack accuracy levels are 6, 6S, 8, and 9. The overall pitch line error of the grinding rack, the thrust of the grinding rack ranges from 10000N to 200000N. The tooth surface roughness of the grinding rack is less than Ra0.8, so the moving noise is very small, less than 45 decibels, the pitch error of the grinding linear rack is less than 0.005mm, the movement is very smooth, there is no abnormal vibration, and the tooth surface of the grinding rack moves stably at high speed. The ground rack has high strength and high acceleration, and the rack surface is treated with rust prevention. It is widely used in machine tools, laser cutting machines, gantry processing, and robotic automation.

Optimize Surface Quality

Grinding can significantly improve the surface finish of the linear rack and reduce surface roughness, thereby reducing friction and wear. Smooth surfaces produce less noise when meshing, which is suitable for applications with strict noise requirements.

Strong Adaptability

Grinded racks can be widely used in various mechanical equipment, such as machine tools, laser cutting machines, gantry processing, and robotic automation, and have strong adaptability.
According to specific needs, ground linear racks can be customized with different sizes, tooth shapes, and materials to meet specific working conditions.

Summary

The grinding process of the linear rack improves the accuracy of the rack, optimizes the surface quality, enhances wear resistance, and improves the meshing performance, significantly improving the overall performance and service life of the rack.
