Rolling island tracks for CNC lathe processing

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

Dongguan Ruibang Model Manufacturing Technology Co., Ltd. has focused on CNC lathe processing and precision parts processing for 14 years. Below we will conduct a detailed analysis of the rolling island rails of CNC lathe processing.

About the ordinary rolling island tracks for CNC lathe processing

The ordinary rolling guides processed by CNC lathes are to arrange rolling elements between the guide rail working surfaces to make rolling friction between the guide rail surfaces. Ordinary rolling guides have a small friction coefficient (usually around 0.003), a small difference in the coefficient of motion and static friction, and are almost unaffected by movement changes. It has the advantages of high positioning accuracy, high sensitivity, and good accuracy retention.

About the linear rolling island rail for CNC lathe processing

Linear rolling guide rail, also known as unit-type linear rolling guide rail, is a new rolling guide rail that has emerged in recent years. Its structural type is composed of rail body, slider, ball, retainer, end cover, etc. When we use the guide rails are fixed to parts that are not moving and the sliders are fixed to the moving parts. When the slider moves along the guide rail body, the ball rolls in the arc straight groove between the guide rail body and the slider, and continuously circulates from the workload area to the non-workload area through the raceway in the end cover, thereby circulating the guide rail continuously, thereby circulating the guide rail through the raceway in the end cover. The movement between the body and the slider becomes the rolling of the ball.

About the rolling island rail blocks for CNC lathe processing

The rolling guide rail block is also called the rolling guide rail support block. It is a rolling guide rail with a rolling element that performs cyclic movement. It is mostly used for medium loads. Its structural type is to guide the rolling element (roller) back from the protective plate, end cover and guide plate. to the holder to the body. When in use, the rolling guide block is installed on the guide surface of the moving parts, and each guide rail is made of at least two. The number of guide blocks depends on the length of the guide rail and the size of the load. Most of the guide rails matching it use steel-inlaid quenched guide rails.

When the moving part moves, the roller rolls between the guide surface of the support member and the body, and at the same time rolls circulating around the body, and the roller does not contact the guide surface of the moving part. The rolling guide rail block is produced by Shenzhen Jinboshi Precision Hardware Co., Ltd. and has a variety of specifications and types for customers to choose from. The characteristics of the rolling guide block are high stiffness, large load-bearing capacity, and easy to disassemble and assemble.

Finally, I would like to remind everyone that linear rolling guides are generally assembled by manufacturers. Their outstanding advantages are that they have no gaps. Compared with ordinary rolling guides, they also have the following major characteristics:

1. High manufacturing accuracy;

2. Maintain high accuracy for a long time;

3. Preload can be preloaded to improve stiffness;

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

5. It has self-adjustment capability and has large allowable errors in the installation base surface.
