4. Basic Structural Composition
4.1 Guide body
The main part of the stainless steel linear rail is usually made of high-strength stainless steel material with high rigidity and wear resistance.
4.2 Rolling body
Generally a ball or roller, located between the guide body and the slider, reducing friction resistance and improving movement stability.
4.3 Slider
Cooperating with the guide body, it can slide on the guide body, carrying the moving parts and realizing precise guidance.
4.4 Reverser
Used to change the movement direction of the rolling body and realize the cyclic movement of the rolling body.
5. Working Principle and Movement Mode
5.1 Working principle
Stainless steel linear rails achieve precise guidance and smooth movement of moving parts through the rolling of rolling elements between the guide body and the slider.
5.2 Movement mode
The slider performs linear reciprocating motion on the guide body, and the rolling of the rolling elements reduces friction resistance and improves movement efficiency and precision.
6. Key Performance Indicators
6.1 Accuracy
The accuracy level of stainless steel linear rails directly affects their performance and life. High-precision guides can provide higher movement accuracy and stability.
6.2 Wear resistance
Stainless steel linear rails need to have high wear resistance to ensure good working performance after long-term use.
6.3 Rigidity
The rigidity of the guide determines its load-bearing capacity and ability to resist deformation. High-rigidity guides can withstand greater loads and maintain stable movement performance.
6.4 Stability
The stability of the guide is crucial to ensure the precise movement of moving parts. Guides with good stability can provide smoother movement effects.
7. Manufacturing Process and Flow
7.1 Raw material selection and preparation
Material selection: Select high-quality stainless steel materials, such as 304 or 316 stainless steel, which have good corrosion resistance and mechanical properties.
Material preparation: Pre-process the stainless steel material by cutting and grinding to ensure that the surface of the material is flat and flawless, ready for subsequent processing.
7.2 Processing equipment and process parameter setting
Processing equipment: Use high-precision CNC machine tools to process the guide rails to ensure processing accuracy and efficiency.
Process parameter setting: Reasonably set the process parameters such as cutting speed, feed rate, and cutting depth according to the characteristics of the stainless steel material and the design requirements of the guide rails to ensure processing quality and efficiency.
