Linear Guideway----ZhejiangKairun

The function of linear guide motion is to support and guide moving parts to make reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, etc.
Slide block - converts motion from curve to straight line. The new guide rail system enables the machine tool to obtain fast feed speed. Under the condition of the same spindle speed, fast feed is the characteristic of linear guide motion. Like plane guide rail, linear guide motion has two basic elements; one is a fixed element as a guide, and the other is a moving element. Since linear guide motion is a standard component, the only thing to do for machine tool manufacturers is to process a plane for installing 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. The guide rail as a guide is hardened steel, which is placed on the installation plane after fine grinding. Compared with the plane guide rail, the geometric shape of the cross section of the linear guide rail is more complex than that of the plane 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 force and subversion torque is very different in design compared with a guide rail that only bears linear force.
The basic function of the fixed element (guide rail) of the linear guide system is like a bearing ring, a bracket for mounting the steel ball, and a "V" shape. The bracket wraps around the top and two sides of the guide rail. In order to support the working parts of the machine tool, a set of linear guides has at least four brackets. For supporting large working parts, the number of brackets can be more than four.
