Briefly describe the advantages and disadvantages of woodworking cutting machine guide rails

The guide rails used by the cutting machine are distinguished from the appearance, and are divided into circular guide rails and linear guide rails. As the name suggests, the circular guide rail looks round, the linear guide rail is rectangular in appearance, and the linear guide rail is also called the square rail. The linear guide rail is widely used in four-process cutting machines, woodworking machining centers and other equipment for the production of panel furniture. It is an important part of the woodworking cutting machine, and its quality is closely related to the quality of the entire machine.

The following is a brief description of the advantages and disadvantages of the woodworking cutting machine guide rail:

1. The advantages of linear guides

1) High positioning accuracy

The linear guide way of motion is smooth rolling, has a small friction coefficient, the difference between static friction and dynamic friction is very small, and there will be no idling slip phenomenon, so the woodworking cutting machine can achieve precise positioning.

2) Small friction resistance

The rolling friction resistance of the linear guide rail can reduce the friction resistance of the sliding guide rail. The lubrication structure is simple, easy to lubricate and effective, and the friction contact surface is low.

3) Easy to repair and maintain

The linear guide rail is easy to install and interchangeable. The slider can be arbitrarily fitted on the same model of guide rail while maintaining the same smoothness and precision. It is easy to assemble and easy to maintain.

2. Disadvantages of wire guide rails

The dust performance is poor. Because the balls on the ball linear guide slider are in direct contact with the guide rail, the dust on the guide rail is easily carried into the bearing, causing problems such as blockage and poor sliding of the slider. Generally, the ball linear guide needs to be used with a dust cover, otherwise the service life will be greatly reduced, and it is not suitable for use in dusty and debris occasions.
