Rolling island rail processed by cnc lathe

The rolling island rails processed by cnc lathes are divided into three types: ordinary rolling island rails, linear rolling island rails, and rolling island rail blocks. This is a rolling island rail commonly used in CNC machine tool processing (lathe processing, milling machine processing, and grinding machine processing).

For 14 years, I have been focusing on CNC lathe processing and precision parts processing. Below we will conduct a detailed analysis of the rolling island rail processed by CNC lathes.

About the ordinary rolling island rail processed by cnc lathe

The ordinary rolling guide rail processed by cnc lathe is to arrange rolling bodies between the working surfaces of the guide rail to make the guide rail. There is rolling friction between the surfaces. Ordinary rolling guides have a small friction coefficient (generally around 0.003), a small difference between the dynamic and static friction coefficients, and are hardly affected by motion changes. It has the advantages of high positioning accuracy, high sensitivity, and good accuracy retention.

About the linear rolling island rails processed by cnc lathes

Linear rolling guides, also known as unit linear rolling guides, are the latest technology in recent years. A type of rolling guide that appears, its structure is composed of a guide body, a slider, a ball, a retainer, and an end cover. When we use it, the guide rail is fixed on the non-moving part, and the slider is fixed on the moving part. When the slider moves along the guide rail body, the balls roll in the arc straight groove between the guide rail body and the slider, and circulate continuously from the working load area to the non-working load area through the raceway in the end cover, so that the guide rail is moved continuously. The movement between the body and the slider becomes the rolling of the balls.

About the rolling island rail block processed by cnc lathe

Rolling rail block, also known as rolling rail support block, is a kind of rolling element Circulating rolling guide rails are mostly used for medium loads. The structure is that the protective plate, end cover and guide plate guide the rolling body (roller) to return, and then to the retainer to the body. When in use, the rolling guide block is installed on the guide surface of the moving part, and each guide rail uses at least two pieces. The number of guide rail blocks depends on the length of the guide rail and the size of the load. The matching guide rails are mostly steel-inlaid quenched guide rails.

When the moving part moves, the roller rolls between the guide rail surface of the supporting part and the main body, and at the same time, it rolls around the main body in a circular manner, and the roller does not contact the guide rail surface of the moving part. The rolling guide block is produced by Shenzhen Jinboshi Precision Hardware Co., Ltd., a professional manufacturer, and has a variety of specifications and types for customers to choose. The rolling guide block is characterized by high rigidity, large bearing capacity, and easy disassembly and assembly.

Finally, I would like to remind everyone that linear rolling guides are generally assembled by manufacturers. Its outstanding advantage is that there is no gap. Compared with ordinary rolling guides, it is also It has the following characteristics:

1. High manufacturing precision;

2. It can maintain high precision for a long time;

3. Preload can be added to improve the Stiffness;

4. It can run at high speed, and the running speed can be greater than 10m/s;

5. It has self-adjustment ability, and the allowable error of the installation base surface is large.
