Product Description

Discover the meticulous craftsmanship behind Zhejiang Cncd Transmission Equipment Co., Ltd.'s state-of-the-art production process for high-precision linear guides:

Material selection: Carefully choose from high carbon steel, alloy steel (like GCr15, SUJ2), or stainless steel for unparalleled durability and performance.
Pretreatment: Employ advanced forging or rolling techniques to eradicate internal defects, enhancing cutting processability through a refined annealing process.
Shaping: Utilize precision milling machines or planers to expertly craft the reference surfaces, grooves, and mounting holes of the guide rail, allowing a precise processing allowance for superior accuracy.
Stress relief annealing: Meticulously eliminate internal stress from rough processing, preventing future deformation and ensuring long-lasting structural integrity.
Quenching and tempering: Elevate surface hardness (reaching HRC58-62) to enhance wear resistance, while tempering effectively reduces brittleness for optimal resilience.
Cryogenic treatment: Stabilize the material matrix, reduce residual austenite, and bolster dimensional stability with precision cryogenic methods.
Precision grinding: Employ cutting-edge CNC grinders for accurate processing of reference surfaces and raceways, achieving exceptional straightness (≤3μm/m), parallelism, and surface roughness (Ra≤0.4μm).
Precision hole processing: Use coordinate grinders to achieve impeccable precision in hole creation, ensuring perfect alignment and functionality.
Superfinishing: Achieve superior surface smoothness (Ra≤0.1μm) through advanced polishing or superfinishing, minimizing friction for seamless operation.
Plating or coating: Enhance wear and rust resistance with specialized treatments such as hard chrome plating (5-10μm thick) or nitriding.
Anti-corrosion treatment: Utilize blackening, phosphating, or protective layer spraying on non-working surfaces to ensure comprehensive corrosion resistance.
Slider processing: Conduct precision milling and grinding of slider inner cavities to guarantee impeccable alignment with the guide rail for peak performance.
Rolling element preparation: Grind and grade steel balls or rollers with precise diameter tolerances (≤0.5μm) for ensured smooth movement and reduced friction.
Pre-assembly: Conduct temporary assembly of slider and guide rail to meticulously evaluate sliding resistance and smoothness.
Clearance adjustment: Fine-tune the micrometer-level gap between guide rail and slider by adjusting preload through interference fit or spring structures for precision control.
Lubrication system integration: Incorporate grease or an advanced automatic lubrication device for effortless and efficient maintenance.
Geometric accuracy detection: Utilize laser interferometers and coordinate measuring machines (CMM) for rigorous assessment of straightness, parallelism, and verticality.
Raceway shape analysis: Employ a profilometer for meticulous analysis, ensuring shape accuracy and flawless performance.
Load test: Rigorously verify deformation under rated dynamic/static loads to guarantee robustness and reliability.
Life test: Conduct prolonged operation simulations to evaluate wear rates and project product longevity with precision.
Noise and vibration test: Ensure smooth, tranquil operation with noise levels maintained at ≤50dB for optimal user experience.
Ultrasonic cleaning: Thoroughly remove processing residues, ensuring exemplary cleanliness and operation readiness of the guide rail.
Rust-proof packaging: Employ vacuum seals or anti-rust oil applications for superior protection during transportation and storage.
Process stability: Diligently monitor grinding parameters such as feed rate and grinding wheel grain size, alongside heat treatment temperature curves for unwavering process stability.
