The guide rail is made of hardened steel and is placed on the mounting plane after fine grinding.
Compared with the flat guide rail, the geometric shape of the cross section of a linear guide is more complex than that of a flat guide rail. The reason for the complexity is that grooves need to be machined on the guide rail to facilitate the movement of the sliding element. The shape and number of grooves depend on the function to be completed by the machine tool.
For example, a guide rail system that bears both linear forces and overturning torques is very different in design from a guide rail that only bears linear forces.
The new guide rail system enables the machine tool to obtain fast feed speeds, which is a characteristic of linear guides when the spindle speed is the same.
Like the flat guide rail, the linear guide rail has two basic elements; one is a fixed element that serves as a guide, and the other is a moving element.
Since the linear guide rail is a standard component, the only thing that the machine tool manufacturer needs to do is to machine a plane for mounting the guide rail and calibrate the parallelism of the guide rail.
Of course, in order to ensure the accuracy of the machine tool, a small amount of scraping and grinding of the bed or column is essential. In most cases, installation is relatively simple.
