Product Description

Discover the meticulously orchestrated production process at the CNCD factory, where high-precision linear guides come to life with unmatched quality and precision engineering.

Material selection: Opt for premium high carbon steel, robust alloy steel (including GCr15, SUJ2), or enduring stainless steel to ensure exceptional durability and performance.
Pretreatment: Engage in forging or rolling the steel to meticulously eliminate internal imperfections, followed by annealing to enhance its cutting processability for superior results.
Shaping: Employ advanced milling machines or planers to preliminarily shape the guide rail's reference surface, grooves, and mounting holes, leaving a precise processing allowance for future refinements.
Stress relief annealing: Conduct vital stress relief annealing to eliminate internal tensions from rough processing, securing dimensional stability and preventing deformation.
Quenching and tempering: Elevate the surface hardness of the guide rail to an impressive HRC58-62, boosting wear resistance while tempering reduces brittleness for optimal integrity.
Cryogenic treatment: Implement cryogenic treatment to stabilize the microstructure, diminish residual austenite, and enhance dimensional stability.
Precision grinding: Utilize CNC surface grinders and guide rail grinders to achieve exceptional straightness (≤3μm/m), meticulous parallelism, and a smooth surface finish (Ra≤0.4μm) on reference surfaces and raceways.
Leverage precision coordinate grinders to meticulously process precision drill holes for unmatched accuracy.
Superfinishing: Polish or superfinish the raceway to achieve an ultra-smooth surface (Ra≤0.1μm), minimizing friction and maximizing performance.
Plating or coating: Employ hard chrome plating (5-10μm thickness) or nitriding treatments for superior wear and rust resistance, extending the lifespan of the guide rail.
Anti-corrosion treatment: Apply blackening, phosphating, or spray protective layers on non-working surfaces for enhanced corrosion protection.
Slider processing: Execute precision milling and grinding of the slider's inner cavity to ensure perfect matching accuracy with the guide rail.
Rolling element preparation: Meticulously grind and grade steel balls or rollers to a diameter tolerance of ≤0.5μm, ensuring seamless movement and superior performance.
Pre-assembly: Conduct temporary assembly of the slider and guide rail to meticulously assess sliding resistance and achieve unparalleled smoothness.
Clearance adjustment: Precisely control micrometer-level gaps between the guide rail and slider by adjusting preload through interference fits or spring structures.
Lubrication system integration: Integrate grease application or install an automatic lubrication device for sustained, smooth operation.
Geometric accuracy detection: Deploy laser interferometers and coordinate measuring machines (CMM) for thorough detection of straightness, parallelism, and verticality with precision.
Employ a profilometer to meticulously analyze the raceway's shape accuracy for optimal performance.
Load test: Conduct rigorous load testing to verify the guide rail's deformation under both dynamic and static loads, ensuring reliability.
Life test: Simulate extended operation to rigorously evaluate the wear rate, ensuring long-lasting performance and durability.
Noise and vibration test: Conduct comprehensive testing to ensure smooth, quiet operation, maintaining noise levels at a serene ≤50dB.
Ultrasonic cleaning: Employ ultrasonic cleaning to effectively remove processing residues, ensuring the guide rail's pristine cleanliness.
Rust-proof packaging: Utilize vacuum sealing or apply anti-rust oil for secure, corrosion-free transportation and storage protection.
Process stability: Diligently monitor grinding parameters (feed rate, grinding wheel grain size) and meticulously control heat treatment temperature curves for consistent process stability.
