2 minuts to learn about the application of high precision linear rail carriage!

 Linear rail carriage is also called linear rail, slide rail, linear guide rail, linear slide rail. It is used for linear reciprocating motions. Linear rail carriage has a higher rated load than linear bearings and can bear a certain torque. Linear rail carriage can be used in Realize high-precision linear motion under high load.
 
The role of high-precision linear rail carriage is to support and guide the moving parts to make reciprocating linear motion in a given direction. According to the nature of friction, linear rail carriage can be divided into sliding friction guide, rolling friction guide, elastic friction guide, fluid friction guide and other types.

 
Linear bearings are mainly used in automated machinery, such as machine tools imported from Germany, paper bowl machines, laser welding machines, etc. Of course, linear bearings and linear shafts are used together. Linear rail carriage is mainly used for high accuracy requirements. Mechanically,
 
Slider-change the movement from a curve to a straight line. The new linear rail carriage system enables the machine to obtain fast feed speeds. With the same spindle speed, fast feed is the characteristic of linear guides. Like a flat rail, a linear rail carriage has two basic elements; one is a fixed element as a guide, and the other is a moving element.

As the precision linear rail carriage is a standard component, for machine tool manufacturers, the only thing to do is to machine a plane where the linear rail carriage is installed and adjust the parallelism of the guide rail. Of course, in order to ensure the accuracy of the machine tool, a small amount of scraping on the bed or column is necessary. In most cases, the installation is relatively simple.
 
The linear rail carriage as the guide is hardened steel, and it is placed on the installation plane after fine grinding. Compared with the flat rail, the cross-sectional geometry of the linear rail carriage is more complex than that of the flat rail. The reason is that the grooves need to be machined on the rails to facilitate the movement of the sliding elements. The shape and number of the grooves depend on the machine tool. Completed functions. For example: A linear rail carriage system that bears both linear forces and subversive moments is very different in design from a linear rail carriage that only receives linear forces.

 
High-precision linear rail carriages use rolling steel balls instead of intermediate media between moving and fixed components. Because the rolling steel ball is suitable for high-speed movement, low friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as the tool holder and carriage of the machine tool. The basic function of the fixed elements (rails) of the linear rail carriage system is like a bearing ring, a steel ball bracket, and a "v" shape. The bracket wraps the top and sides of the rail. To support the machine's working parts, a set of linear guides has at least four brackets. For supporting large working parts, the number of supports can be more than four.
