Product Description

Witness the exceptional craftsmanship in CNCD factory's production of high-precision linear guides:

Material selection: Opt for premium high carbon steel, superior alloy steel (like GCr15, SUJ2), or durable stainless steel,
Pretreatment: Expertly forge or roll the steel to eradicate internal imperfections, enhancing cutting efficiency through meticulous annealing.
Shaping: Employ advanced milling machines or planers to initially craft the reference surface, grooves, and mounting holes of the guide rail, skillfully leaving a fine processing allowance.
Stress relief annealing: Meticulously eliminate internal stress from rough processing to avert potential deformations.
Quenching and tempering: Elevate the surface hardness of the guide rail (typically achieving HRC58-62), boosting wear resistance while tempering reduces brittleness for longevity.
Cryogenic treatment: Precisely stabilize the internal structure, minimize residual austenite, and enhance dimensional stability.
Precision grinding: Utilize cutting-edge CNC surface and guide rail grinders to refine the reference surface and raceway of the guide rail, ensuring impeccable straightness (commonly ≤3μm/m), parallelism, and surface smoothness (Ra≤0.4μm).
Deploy coordinate grinders for processing with precision in holes.
Superfinishing: Significantly reduce the surface roughness of the raceway (Ra≤0.1μm) via polishing or superfinishing techniques to minimize friction.
Plating or coating: Employ techniques like hard chrome plating (thickness 5-10μm) or nitriding to significantly boost wear and rust resistance.
Anti-corrosion treatment: Execute blackening, phosphating, or spray a protective layer on non-working surfaces to enhance durability.
Slider processing: Conduct precision milling and grinding on the slider's inner cavity to ensure perfect alignment with the guide rail.
Rolling element preparation: Carefully grind and grade steel balls or rollers, maintaining a diameter tolerance of ≤0.5μm for flawless movement.
Pre-assembly: Perform a temporary assembly of the slider and guide rail to measure sliding resistance and ensure seamless operation.
Clearance adjustment: Meticulously control the micrometer-level gap between the guide rail and slider by adjusting preload (via interference fit or spring structure).
Lubrication system integration: Infuse grease or install an automated lubrication device for optimal performance.
Geometric accuracy detection: Deploy laser interferometers and coordinate measuring machines (CMM) to verify straightness, parallelism, verticality, and more.
The profilometer provides an in-depth analysis of the raceway's shape accuracy.
Load test: Confirm performance under designated dynamic and static loads, ensuring robustness.
Life test: Simulate extended operation to rigorously evaluate wear rate and durability.
Noise and vibration test: Guarantee whisper-quiet operation with noise levels capped at ≤50dB.
Ultrasonic cleaning: Diligently remove processing residues, ensuring the immaculate cleanliness of the guide rail.
Rust-proof packaging: Secure with vacuum sealing or apply anti-rust oil to prevent corrosion during transit and storage.
Process stability: Vigilantly monitor grinding parameters (such as feed rate, grinding wheel grain size) alongside the heat treatment temperature curve for unmatched consistency.
