Product Description

Explore the intricately detailed production journey of CNCD factory's high-precision linear guides, where precision and quality are paramount.

Material Selection: Handpick only the finest high-carbon steel, alloy steel (like GCr15, SUJ2), or stainless steel to ensure unparalleled strength and durability.
Pretreatment: Through forging or rolling, we meticulously eliminate internal defects, while annealing enhances the cuttability, paving the way for excellence.
Shaping: Utilize advanced milling machines or planers to meticulously craft the reference surface, grooves, and mounting holes of the guide rail, with precision processing in mind.
Stress Relief Annealing: Effortlessly dispel internal stresses from rough processing, ensuring shape retention and preventing undesired deformation.
Quenching and Tempering: Boost the surface hardness of the guide rail to a robust HRC58-62, significantly enhancing wear resistance, with tempering reducing brittleness.
Cryogenic Treatment: Further stabilize the microstructure, minimizing residual austenite for enhanced dimensional stability.
Precision Grinding: Employ state-of-the-art CNC surface grinders for impeccable straightness (≤3μm/m), parallelism, and surface smoothness (Ra≤0.4μm).
Precision Holes: Achieve ultimate precision with coordinate grinders, ensuring each hole meets exacting standards.
Superfinishing: Elevate the raceway's surface refinement to Ra≤0.1μm, minimizing friction through delicate polishing or superfinishing.
Plating or Coating: Opt for hard chrome plating (5-10μm thickness) or nitriding to robustly fortify against wear and rust.
Anti-Corrosion Treatment: Employ blackening, phosphating, or a protective spray to shield non-working surfaces from corrosion.
Slider Processing: Perfect precision milling and grinding of the slider's inner cavity to ensure flawless compatibility with the guide rail.
Rolling Element Preparation: Flawlessly grind and grade steel balls or rollers, achieving a diameter tolerance of ≤0.5μm for seamless motion.
Pre-Assembly: Conduct a temporary assembly to precisely gauge sliding resistance and motion fluidity.
Clearance Adjustment: Masterfully control micrometer-level gaps by meticulously adjusting preload for optimal fit and function.
Lubrication System Integration: Seamlessly incorporate grease or an automatic lubrication device to ensure enduring performance.
Geometric Accuracy Detection: Utilize laser interferometers and CMM to scrutinize every aspect of straightness, parallelism, and verticality.
Profilometer Analysis: Precision dictates as the profilometer evaluates the raceway's shape accuracy with meticulous attention to detail.
Load Test: Rigorously assess deformation under rated dynamic/static loads, assuring reliability under pressure.
Life Test: Simulate extended operation to comprehensively evaluate the wear rate and durability over time.
Noise and Vibration Test: Guarantee smooth, whisper-quiet operation with noise levels kept to a minimum (≤50dB).
Ultrasonic Cleaning: Thoroughly cleanse with ultrasonic technology, eradicating processing residues and ensuring immaculate guide rail cleanliness.
Rust-Proof Packaging: Employ vacuum sealing or anti-rust oil coating to safeguard against corrosion during transport and storage.
Process Stability: Rigidly monitor grinding parameters and heat treatment curves for unwavering consistency and quality.
