Product Description

Experience the meticulous craftsmanship of CNCD factory in producing high-precision linear guides, where precision meets perfection.

Material selection: Opt for superior high carbon steel, robust alloy steel (like GCr15, SUJ2), or resilient stainless steel for unmatched durability.
Pretreatment: Engage in forging or rolling the steel to eradicate internal defects, enhancing machinability through effective annealing.
Shaping: Employ advanced milling machines or planers to begin processing the reference surfaces, grooves, and mounting holes with precision, ensuring a fine allowance for further processing.
Stress relief annealing: Carefully eliminate internal stress from rough processing, preserving the integrity and preventing future deformation.
Quenching and tempering: Elevate the surface hardness of the guide rail to an impressive HRC58-62, boosting wear resistance; tempering further diminishes brittleness.
Cryogenic treatment: Achieve superior dimensional stability by stabilizing the organization and minimizing residual austenite.
Precision grinding: Utilize state-of-the-art CNC surface grinders and guide rail grinders to meticulously process the reference surface and raceway, maintaining straightness (≤3μm/m), parallelism, and exemplary surface roughness (Ra≤0.4μm).
Harness the precision of coordinate grinders to craft perfect precision holes.
Superfinishing: Achieve remarkable surface smoothness on the raceway (Ra≤0.1μm) through polishing or superfinishing techniques, significantly cutting down on friction.
Plating or coating: Employ hard chrome plating (5-10μm) or nitriding to fortify wear and rust resistance, ensuring long-lasting quality.
Anti-corrosion treatment: Protect with blackening, phosphating, or a sprayed protective layer on non-working surfaces for enhanced longevity.
Slider processing: Execute precision milling and grinding of the slider's inner cavity for an impeccable fit with the guide rail.
Rolling element preparation: Grind and grade steel balls or rollers with precision (diameter tolerance ≤0.5μm) for seamless movement.
Pre-assembly: Temporarily assemble the slider and guide rail to meticulously test for minimal sliding resistance and optimal smoothness.
Clearance adjustment: Fine-tune the micrometer-level gap between the guide rail and slider by adjusting preload methods like interference fit or spring structures.
Lubrication system integration: Enhance performance by adding grease or integrating an automated lubrication device.
Geometric accuracy detection: Utilize advanced laser interferometers and coordinate measuring machines (CMM) to verify straightness, parallelism, verticality, and other crucial metrics.
Profilometer: Analyze the exact shape accuracy of the raceway for guaranteed precision.
Load test: Rigorously verify deformation under rated dynamic and static loads to ensure reliability.
Life test: Simulate extended operation to thoroughly evaluate the wear rate and ensure longevity.
Noise and vibration test: Guarantee flawless operation, maintaining noise levels at or below 50dB for a tranquil experience.
Ultrasonic cleaning: Remove all processing residues with precision, ensuring the guide rail's pristine cleanliness.
Rust-proof packaging: Employ vacuum sealing or apply anti-rust oil to protect against corrosion during transit and storage.
Process stability: Maintain strict oversight of grinding parameters (such as feed rate and grinding wheel grain size) and adhere to precise heat treatment temperature curves.
