Product Description

Dive into the meticulous production process of CNCD's high-precision linear guides, where every step ensures excellence.

Material selection: We meticulously choose from high carbon steel, alloy steel like GCr15, SUJ2, or robust stainless steel, setting the foundation for superior quality.
Pretreatment: Through forging or rolling, the steel is refined to eradicate internal flaws, while annealing enhances its machinability, setting the stage for precision crafting.
Shaping: Utilize cutting-edge milling machines or planers to initially craft the reference surface, grooves, and mounting holes of the guide rail, artfully leaving room for fine processing.
Stress relief annealing: An essential step to eradicate internal stress from rough processing, ensuring the guide rail remains deformation-free in future stages.
Quenching and tempering: Elevate the guide rail's surface hardness dramatically (HRC58-62) while improving wear resistance; tempering is key to reducing brittleness.
Cryogenic treatment: A transformative step to further stabilize the internal structure, diminish residual austenite, and enhance dimensional stability.
Precision grinding: Employ state-of-the-art CNC surface and guide rail grinders, ensuring unparalleled straightness (≤3μm/m), impeccable parallelism, and finely honed surface roughness (Ra≤0.4μm).
Leverage precision coordinate grinders to meticulously craft precision holes with unmatched accuracy.
Superfinishing: Achieve a remarkable reduction in raceway surface roughness (Ra≤0.1μm) through polishing or superfinishing, minimizing friction for optimal performance.
Plating or coating: Apply techniques like hard chrome plating (5-10μm thickness) or nitriding to significantly boost wear and rust resistance.
Anti-corrosion treatment: Employ methods such as blackening, phosphating, or protective layer spraying to safeguard non-working surfaces against corrosion.
Slider processing: Precision milling and grinding ensure the slider's inner cavity matches the guide rail with impeccable accuracy.
Rolling element preparation: Precision grind and grade steel balls or rollers to a diameter tolerance of ≤0.5μm, guaranteeing smooth, flawless movement.
Pre-assembly: Temporarily unite the slider and guide rail to meticulously assess sliding resistance and smoothness, ensuring perfect motion.
Clearance adjustment: Precisely control the micrometer-level gap between the guide rail and slider through advanced preload adjustments, such as interference fit or spring structures.
Lubrication system integration: Seamlessly incorporate grease or an automated lubrication device for effortless operation.
Geometric accuracy detection: Employ laser interferometers and CMM to rigorously assess straightness, parallelism, verticality, and more.
Profilometer: Conduct precise analyses of raceway shape accuracy, ensuring unmatched precision.
Load test: Rigorously verify guide rail deformation under rated dynamic or static loads, ensuring structural integrity.
Life test: Simulate extended operation to meticulously evaluate wear rates, promising long-lasting performance.
Noise and vibration test: Confirm seamless operation with noise levels not exceeding 50dB, ensuring a tranquil working environment.
Ultrasonic cleaning: Thoroughly remove any processing residues, guaranteeing pristine guide rail cleanliness.
Rust-proof packaging: Utilize vacuum sealing or apply anti-rust oil, protecting the guide rail from corrosion during transport and storage.
Process stability: Diligently monitor every grinding parameter, from feed rate to grinding wheel grain size, and maintain precision in heat treatment temperature curves for ultimate consistency.
