Product Description

Uncover the meticulous craftsmanship of Zhejiang Cncd Transmission Equipment Co., Ltd., where the production process of high-precision linear guides is an art form in itself:

Material selection: Our experts meticulously select only the finest high carbon steel, alloy steel (such as GCr15, SUJ2), or stainless steel for unmatched durability.
Pretreatment: The steel undergoes forging or rolling to eradicate internal defects, followed by annealing to enhance its cutting processability.
Shaping: With precision tools like milling machines or planers, we expertly craft the reference surface, grooves, and mounting holes, ensuring a refined processing allowance is left for further perfection.
Stress relief annealing: This crucial step alleviates internal stress from rough processing, safeguarding the guide rail against any future deformation.
Quenching and tempering: Our process amplifies surface hardness to HRC58-62, significantly boosting wear resistance while tempering reduces brittleness for lasting resilience.
Cryogenic treatment: A sophisticated technique to stabilize the structure, diminish residual austenite, and bolster dimensional stability.
Precision grinding: Utilizing CNC surface and guide rail grinders, we hone the reference surface and raceway to ensure unparalleled straightness (≤3μm/m), parallelism, and surface perfection (Ra≤0.4μm).
Our skilled technicians employ coordinate grinders to achieve immaculate precision in hole processing.
Superfinishing: By polishing or superfinishing, we refine the raceway surface to an exceptional smoothness (Ra≤0.1μm) to minimize friction and optimize performance.
Plating or coating: Employing hard chrome plating or nitriding, we fortify the guide rail with enhanced wear and rust resistance.
Anti-corrosion treatment: We apply blackening, phosphating, or a protective spray on non-working surfaces, ensuring enduring defense against corrosion.
Slider processing: Through precision milling and grinding, we ensure the inner cavity of the slider perfectly matches the guide rail for seamless integration.
Rolling element preparation: Meticulously ground and graded steel balls or rollers, with a diameter tolerance of ≤0.5μm, guarantee fluid movement.
Pre-assembly: The slider and guide rail are temporarily assembled to fine-tune sliding resistance and enhance smoothness.
Clearance adjustment: By adjusting the preload, such as interference fit or spring structures, we achieve micrometer-level control of the gap between the guide rail and slider.
Lubrication system integration: Whether through grease or an automatic lubrication device, we ensure superior lubrication for optimal operation.
Geometric accuracy detection: Employ laser interferometers and coordinate measuring machines (CMM) to meticulously verify straightness, parallelism, and verticality.
Utilizing a profilometer, we scrutinize the shape accuracy of the raceway to ensure precision.
Load test: Rigorously verify deformation under rated dynamic and static loads to guarantee durability.
Life test: Our simulations mimic long-term operations to assess the wear rate for enduring performance.
Noise and vibration test: Ensuring whisper-quiet operation, our products maintain noise levels at a serene ≤50dB.
Ultrasonic cleaning: A thorough cleansing process to eliminate any residual particles, ensuring the pristine condition of the guide rail.
Rust-proof packaging: Special vacuum sealing and anti-rust oil applications protect against corrosion during transport and storage.
Process stability: Our vigilant monitoring of grinding parameters and heat treatment temperature curves ensures unwavering process consistency.
