Product Description

Witness the precision craftsmanship at CNCD factory, where our high-precision linear guides come to life through a meticulous production process:

1. Material Selection: Opt for superior high carbon steel, alloy steel (like GCr15, SUJ2), or stainless steel to ensure unrivaled durability and performance.
2. Pretreatment: Employ forging or rolling techniques to remove internal imperfections. Through annealing, we enhance the steel's machinability.
3. Shaping: Utilize advanced milling machines or planers to initially shape the reference surfaces, grooves, and mounting holes, keeping a precision allowance for later stages.
4. Stress Relief Annealing: This critical step releases internal stresses from rough processing, setting the stage for flawless subsequent operations.
5. Quenching and Tempering: Elevate the guide rail's surface hardness to HRC58-62, enhancing wear resistance. Tempering then reduces brittleness for robustness.
6. Cryogenic Treatment: Solidify the microstructure, decrease residual austenite, and ensure superior dimensional stability.
7. Precision Grinding: Employ CNC surface and rail grinders for impeccable straightness (≤3μm/m), parallelism, and surface smoothness (Ra≤0.4μm) of the guide rail.
8. Coordinate Grinding: Precision holes are crafted with coordinate grinders, ensuring immaculate accuracy.
9. Superfinishing: Achieve ultra-low surface roughness (Ra≤0.1μm) through polishing or superfinishing, minimizing friction to enhance glide.
10. Plating/Coating: Apply hard chrome plating (5-10μm thick) or nitriding for superior wear and rust resistance.
11. Anti-Corrosion Treatment: Employ blackening, phosphating, or protective layer spraying on non-working surfaces to shield against corrosion.
12. Slider Processing: Precision mill and grind the slider's inner cavity to achieve perfect alignment with the guide rail.
13. Rolling Element Preparation: Finely grind and grade steel balls or rollers, ensuring a diameter tolerance of ≤0.5μm for seamless operation.
14. Pre-Assembly: Temporarily assemble the slider and guide rail, assessing sliding resistance and ensuring smoothness.
15. Clearance Adjustment: Fine-tune the micrometer-level gap between the guide rail and slider by adjusting preload (via interference fit or spring structure).
16. Lubrication System Integration: Introduce grease or install an automatic lubrication device for optimal performance.
17. Geometric Accuracy Detection: Employ laser interferometers and coordinate measuring machines (CMM) to verify straightness, parallelism, and verticality.
18. Shape Accuracy Analysis: Profilometers meticulously analyze the raceway's shape accuracy, ensuring precision.
19. Load Testing: Evaluate deformation under rated dynamic/static load conditions for reliability.
20. Life Testing: Simulate long-term operations, assessing wear rates to ensure longevity.
21. Noise and Vibration Testing: Conduct tests to guarantee smooth, quiet operation, with noise levels ≤50dB.
22. Ultrasonic Cleaning: Eliminate processing residues, ensuring pristine cleanliness of the guide rail.
23. Rust-Proof Packaging: Employ vacuum sealing or anti-rust oil application to guard against corrosion during transit and storage.
24. Process Stability: Rigorously monitor grinding parameters (like feed rate and grinding wheel grain size) and heat treatment temperature curves for optimal production.
