Product Description

Discover the meticulous production process of high-precision linear guides at the renowned CNCD factory:

Material Selection: Opt for superior high carbon steel, alloy steel (like GCr15, SUJ2), or stainless steel, ensuring quality at the core.
Pretreatment: Expertly forge or roll steel to address internal imperfections, enhancing machinability through precise annealing.
Shaping: Skillfully employ milling machines or planers for initial processing of the guide rail's reference surface, grooves, and mounting holes, maintaining precision allowances.
Stress Relief Annealing: Effectively remove stresses from rough processing, stabilizing the material to prevent future deformation.
Quenching and Tempering: Elevate surface hardness (reaching HRC58-62) and bolster wear resistance while tempering to minimize brittleness.
Cryogenic Treatment: Achieve superior organizational stability, significantly reducing residual austenite for enhanced dimensional stability.
Precision Grinding: Utilize CNC surface grinders to finesse the guide rail's reference surface and raceway, ensuring impeccable straightness (≤3μm/m), parallelism, and surface smoothness (Ra≤0.4μm).
Employ coordinate grinders for the accurate processing of precision holes.
Superfinishing: Achieve exceptional surface smoothness (Ra≤0.1μm) by polishing or superfinishing, minimizing friction to optimal levels.
Plating or Coating: Augment wear and rust resistance with techniques like hard chrome plating (5-10μm thick) or nitriding.
Anti-Corrosion Treatment: Implement blackening, phosphating, or protective sprays on non-working surfaces to prevent corrosion.
Slider Processing: Precisely mill and grind the slider's inner cavity to ensure accurate matching with the guide rail.
Rolling Element Preparation: Meticulously grind and grade steel balls or rollers, maintaining a diameter tolerance of ≤0.5μm for seamless movement.
Pre-Assembly: Temporarily assemble the slider and guide rail to assess sliding resistance and operational smoothness.
Clearance Adjustment: Finely tune the micrometer-level gap between guide rail and slider by adjusting preload, such as interference fit or spring structures.
Lubrication System Integration: Incorporate grease or install advanced automatic lubrication devices for optimal operation.
Geometric Accuracy Detection: Deploy laser interferometers and coordinate measuring machines (CMM) to meticulously assess straightness, parallelism, and verticality.
Profilometer Analysis: Thoroughly analyze the raceway's shape accuracy for superior performance.
Load Test: Confirm deformation resilience under both rated dynamic and static loads.
Life Test: Simulate extended operation to evaluate wear rates over time for longevity assurance.
Noise and Vibration Test: Ensure whisper-quiet operation, maintaining noise levels at or below 50dB.
Ultrasonic Cleaning: Remove residual processing materials, ensuring pristine guide rail cleanliness.
Rust-Proof Packaging: Utilize vacuum sealing or apply anti-rust oil to safeguard against corrosion during transit and storage.
Process Stability: Vigilantly monitor grinding parameters (feed rate, grinding wheel grain size) and the heat treatment temperature curve for consistent quality.
