Instructions for Linear Guideway

Self-aligning ability:

The DF (45-°45)° combination from the circular groove can be absorbed by the elasticity of the steel ball and the transfer of the contact point during the installation, even if the mounting surface is somewhat deviated, it can be absorbed by the inside of the line slider. The effect of automatic self-aligning ability is produced to obtain a smooth motion with high precision and stability.

Interchangeable:

Due to the strict control of production precision, the size of the linear guide can be maintained within a certain level, and the slider has a retainer design to prevent the steel balls from falling off. Therefore, some series of precisions are interchangeable, and customers can order the guide rails or Slider can also store guide rails and sliders separately to reduce storage space.

 

High rigidity in all directions

 

The four-row circular groove is matched with the contact angle of 45 degrees such as four rows of steel balls to make the steel ball reach the ideal two-point contact structure, which can withstand the load from the up and down and the left and right directions; if necessary, it can apply preload to improve rigidity.

Application areas:

1. Linear guides are mainly used in automation machinery, such as machine tools imported from Germany, paper bowl machines, laser welding machines, etc. Of course, linear guides and linear axes are used.

 

2. The linear guide rail is mainly used on the mechanical structure with higher precision requirements. The intermediate medium is not used between the moving component and the fixed component of the linear guide rail, and the rolling steel ball is used. Because the rolling steel ball is suitable for high-speed movement, small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as tool holders and carriages of machine tools. If the force acting on the steel ball is too large, the steel ball is subjected to the preloading time for too long, resulting in an increase in the kinematic resistance of the bracket.

 

Note:

 

Linear guides are precision parts, so they require a very careful attitude when used. Even if high-performance linear guides are used, if they are not used properly, the expected performance will not be achieved, and the linear guides will be easily damaged. Therefore, the following matters should be noted when using linear guides:

 

Prevent corrosion

 

When taking the linear guide directly by hand, wash off the sweat on your hands and apply high-quality mineral oil before handling. Pay special attention to rust prevention during the rainy season and summer.

 

Keep the environment clean

 

Keeping the linear guide and its surroundings clean Even if tiny dust that is invisible to the naked eye enters the guide rail, it will increase the wear, vibration and noise of the guide rail.

 

Installation should be careful

 

Linear guides should be carefully and carefully used during installation. Strong stamping is not allowed. It is not allowed to directly hit the guide rails with a hammer. It is not allowed to transmit pressure through the rolling elements.

 

The installation tool should be suitable

 

Linear guides use special tools with appropriate and accurate installation tools, and try to avoid the use of cloth and short fibers.

Clean the rails:

The guide rail and the linear shaft are one of the core components of the equipment, and its function is to guide and support. In order to ensure the machine has high machining accuracy, the guide rail and straight line are required to have high guiding precision and good motion stability. During the operation of the equipment, due to the large amount of corrosive dust and smoke generated during processing, the smoke and dust are deposited on the surface of the guide rail and the linear shaft for a long time, which has a great influence on the processing precision of the equipment. An etch point is formed on the surface of the linear axis of the guide rail to shorten the service life of the device. In order to make the machine work stably and ensure the quality of the products, it is necessary to carefully carry out the daily maintenance of the guide rails and linear axes. Note: Please prepare the cleaning rails - dry cotton cloth, lubricating oil. The guide rail of the engraving machine is divided into a linear guide rail and a roller guide rail. Cleaning the linear guide: first move the laser head to the far right (or left side), find the linear guide, wipe it with a dry cotton cloth until it is bright and dust-free, plus a little oil (can use sewing machine oil, do not use oil) , slowly push the laser head a few times to allow the lubricant to be evenly distributed. Cleaning the roller guide: Move the beam to the inside, open the end cover on both sides of the machine, find the guide rail, wipe the place where the guide rails on both sides are in contact with the roller with a dry cotton cloth, then move the beam to clean the remaining place.

Development Overview:

The sustained and rapid growth of China's economy has provided a huge market space for linear guide products. The strong temptation of the Chinese market has made the world focus on the Chinese market. In the short period of reform and opening up, China's linear guide manufacturing industry The huge production capacity that has been formed has made the world look impressive. With the continuous expansion of China's power industry, data communication industry, urban rail transit industry, automobile industry and shipbuilding industry, the demand for linear guides will also grow rapidly. In the future, the linear guide rail industry has great potential for development.
