Product Description

Discover the CNCD factory's meticulous and highly specialized production process for crafting high-precision linear guides, setting a benchmark in precision engineering!

Material selection is paramount: Opt for high carbon steel, robust alloy steel (such as GCr15, SUJ2), or the enduring strength of stainless steel, ensuring unparalleled foundation quality.
Pretreatment stage: Meticulously forge or roll the steel, eliminating any internal defects, while annealing elevates cutting processability to new heights.
Shaping phase: Employ state-of-the-art milling machines or planers to expertly prepare the guide rail's reference surface, grooves, and mounting holes, reserving a fine processing allowance for precision.
Stress relief annealing: This crucial step eradicates internal stress from rough processing, safeguarding the product against future deformations.
Quenching and tempering: Elevate the guide rail's surface hardness to an impressive HRC58-62, enhancing wear resistance, while tempering artfully reduces brittleness.
Cryogenic treatment: Achieve unprecedented dimensional stability by minimizing residual austenite and stabilizing the structure further.
Precision grinding: Harness CNC surface grinders and rail grinders to impeccably process the guide rail's reference surface and raceway, ensuring straightness (typically ≤3μm/m), parallelism, and a surface roughness (Ra≤0.4μm) that is second to none.
Utilize high-precision coordinate grinders to skillfully process exacting precision holes.
Superfinishing: Through polishing or superfinishing, reduce the raceway's surface roughness (Ra≤0.1μm) to minimize friction to a whisper.
Plating or coating: Opt for enhancements such as hard chrome plating (thickness 5-10μm) or nitriding, dramatically boosting both wear and rust resistance.
Anti-corrosion treatment: Employ blackening, phosphating, or a protective spray on non-working surfaces for superior corrosion resistance.
Slider processing: Through precision milling and grinding, ensure the slider's inner cavity impeccably matches the guide rail, guaranteeing unmatched accuracy.
Rolling element preparation: With exacting precision, steel balls or rollers are ground and graded, maintaining a diameter tolerance of ≤0.5μm to ensure flawlessly smooth movement.
Pre-assembly: Perform a provisional assembly of the slider and guide rail to assess sliding resistance and ensure optimal smoothness.
Clearance adjustment: Achieve micrometer-level control over the gap between guide rail and slider by precisely adjusting the preload through interference fit or spring structures.
Lubrication system integration: Expertly apply grease or install an automatic lubrication system to assure continuous, seamless operation.
Geometric accuracy detection: Deploy laser interferometers and CMM machines to meticulously verify straightness, parallelism, and verticality, ensuring peak precision.
Employ profilometers to analytically assess the raceway's shape accuracy, ensuring absolute precision.
Load test: Rigorously verify deformation under dynamic/static loads, affirming reliability under stress.
Life test: Simulate extensive long-term operation, meticulously evaluating the wear rate to ensure lasting durability.
Noise and vibration test: Conduct tests to maintain unerringly smooth operation, adhering to noise standards as low as ≤50dB.
Ultrasonic cleaning: Thoroughly remove processing residues, ensuring the guide rail's pristine cleanliness.
Rust-proof packaging: Secure against corrosion with vacuum sealing or anti-rust oil, guaranteeing pristine condition during transport and storage.
Process stability: Rigorously monitor grinding parameters, such as feed rate and wheel grain size, alongside heat treatment temperature curves, to ensure unwavering process stability.
