How to choose the quality of the guide rail for the woodworking cutting machine?

The square rail of the woodworking cutting machine is divided into square linear guide rail and round rail. Different guide rails are selected for different CNC equipment. According to the structure and use of different CNC equipment, the styles of guide rails used are also different.

The circular guide of the cutting machine is a cylindrical linear guide, which requires limited support and has poor rigidity. The circular guide rail has high bearing capacity, high average precision, relatively low cost, short production cycle and convenient installation, and has become a substitute for square linear guide rails in many occasions. The price of square rail is higher than that of round rail, which mainly depends on budget, industry and precision requirements.

Features of the square rail of the cutting machine:

Low frictional resistance for long-term precision. The rolling friction of the linear guide of the feeding machine can be reduced to 1/20~1/40 of the friction resistance of the sliding guide. The lubrication structure is simple, the lubrication is easy, the lubrication effect is good, the friction contact surface wears the bottom, and the running accuracy can be maintained for a long time.

The rolling motion of linear guides has a small friction coefficient and a small gap between static friction and dynamic friction, which can achieve micron-level positioning accuracy.

It can withstand high load capacity in four directions, and at the same time, it can easily improve the performance and load capacity of the CNC advertising engraving machine by applying preload and the number of sliders. It is suitable for high-speed applications, with low frictional resistance, low requirements for equipment driving horsepower, large energy saving effect, small movement wear and low temperature rise effect, and can meet the requirements of mechanical miniaturization and high speed at the same time.
