Rolling Island Track Processed by CNC Lathe

The rolling guide rails used in CNC lathe machining are divided into three types: ordinary rolling guide rails, linear rolling guide rails, and rolling guide rail blocks. These are the commonly used rolling guide rails in today's CNC machine tool machining (lathe machining, milling machine machining, grinding machine machining).

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

About the Ordinary Rolling Guide Rails of CNC Lathe Machining

The ordinary rolling guide rails for CNC lathe machining are those where rolling elements are arranged between the working surfaces of the guide rails, making the friction between the guide rail surfaces rolling friction. Ordinary rolling guide rails have a small friction coefficient (usually around 0.003), and the difference between dynamic and static friction coefficients is small, which is hardly affected by changes in motion. They have the advantages of high positioning accuracy, high sensitivity, and good precision retention.

About the Linear Rolling Guide Rails of CNC Lathe Machining

Linear rolling guide rails, also known as unit-type linear rolling guide rails, are a new type of rolling guide rail that has emerged in recent years. Their structural form consists of a guide rail body, a slider, balls, a retainer, end caps, etc. When in use, the guide rail is fixed on the non-moving component, and the slider is fixed on the moving component. When the slider moves along the guide rail body, the balls roll in the arc straight grooves between the guide rail body and the slider, and continuously circulate from the working load area to the non-working load area through the raceway in the end cap, thereby converting the movement between the guide rail body and the slider into the rolling of the balls.

About the Rolling Guide Rail Blocks of CNC Lathe Machining

Rolling guide rail blocks, also known as rolling guide rail support blocks, are a type of rolling guide rail where the rolling elements perform circular motion. They are mostly used for medium loads. Their structural form includes a protective plate, end caps, and guide pieces that guide the rolling elements (rollers) to return, then to the retainer and the main body. In use, rolling guide rail blocks are installed on the guide rail surface of the moving component. At least two blocks are used for each guide rail, and the number of guide rail blocks depends on the length of the guide rail and the magnitude of the load. The matching guide rails mostly adopt镶钢 quenched guide rails.

When the moving component moves, the rollers roll between the guide rail surface of the supporting component and the main body, and at the same time, they roll circularly around the main body. The rollers do not come into contact with the guide rail surface of the moving component. Rolling guide rail blocks are professionally produced by Shenzhen Jinboshi Precision Hardware Co., Ltd., with various specifications and types for customers to choose from. The characteristics of rolling guide rail blocks are high rigidity, large load-carrying capacity, and easy disassembly and assembly.

Finally, it should be reminded that linear rolling guide rails are generally assembled by the manufacturer. Their outstanding advantage is that there is no gap. Compared with ordinary rolling guide rails, they also have the following characteristics:

1. High manufacturing precision;

2. Can maintain high precision for a long time;

3. Preload can be applied to improve rigidity;

4. Can run at high speed, with a running speed greater than 10m/s;

5. Have self-adjusting ability, allowing large errors in the installation base surface.
