Product Description

Embark on a journey through the exemplary production process at the CNCD factory, where high-precision linear guides are crafted with unmatched expertise and dedication:

Material Selection: Begin with an unwavering commitment to quality by selecting only the finest high carbon steel, alloy steel (including GCr15, SUJ2), or robust stainless steel. This choice sets the foundation for excellence.
Pretreatment: Elevate the raw steel through a meticulous process of forging or rolling to eradicate internal defects. Enhance its cutting processability with precision annealing, ensuring superior performance.
Shaping: Engage advanced milling machines or planers to meticulously craft the guide rail's reference surface, grooves, and mounting holes, leaving a fine processing allowance for perfection.
Stress Relief Annealing: Masterfully eliminate internal stress from rough processing, safeguarding against any deformation in future stages and ensuring the guide rail's integrity.
Quenching and Tempering: Elevate the guide rail's surface hardness to an impressive HRC58-62, significantly enhancing wear resistance, while tempering reduces brittleness for a balanced strength.
Cryogenic Treatment: Dive into an advanced process to further stabilize the metal's structure, reduce residual austenite, and enhance dimensional stability, ensuring long-term precision.
Precision Grinding: Utilize state-of-the-art CNC surface grinders and guide rail grinders to achieve unparalleled straightness (≤3μm/m), parallelism, and a surface smoothness of Ra≤0.4μm, guaranteeing flawless performance.
Employ coordinate grinders to meticulously process precision holes, ensuring impeccable accuracy.
Superfinishing: Attain a superior surface by reducing raceway roughness to Ra≤0.1μm through polishing or superfinishing, minimizing friction for optimal motion.
Plating or Coating: Enhance the guide rail's longevity with hard chrome plating (5-10μm thickness) or nitriding treatment, significantly boosting wear and rust resistance.
Anti-Corrosion Treatment: Implement blackening, phosphating, or protective spray on the non-working surfaces to fortify against corrosion, preserving the guide's pristine condition.
Slider Processing: With precision milling and grinding, the inner cavity of the slider is expertly crafted to ensure a perfect match with the guide rail, achieving impeccable compatibility.
Rolling Element Preparation: Steel balls or rollers are meticulously ground and graded with a diameter tolerance of ≤0.5μm, ensuring the smoothest, most precise movement.
Pre-Assembly: Temporarily unite the slider and guide rail, assessing sliding resistance and smoothness to ensure seamless operation.
Clearance Adjustment: Meticulously control the micrometer-level gap between guide rail and slider via precise preload adjustments, ensuring optimal fit and function.
Lubrication System Integration: Incorporate grease or sophisticated automatic lubrication devices to maintain optimal performance.
Geometric Accuracy Detection: Employ laser interferometers and coordinate measuring machines (CMM) to rigorously assess straightness, parallelism, and verticality with precision.
Profilometer Analysis: Scrutinize the raceway's shape accuracy for precision perfection.
Load Test: Conduct comprehensive tests to verify the guide rail's deformation under dynamic and static loads, ensuring resilience and reliability.
Life Test: Simulate long-term usage to evaluate wear rates, ensuring durability and longevity.
Noise and Vibration Test: Guarantee smooth, silent operation with noise levels not exceeding 50dB, ensuring a serene work environment.
Ultrasonic Cleaning: Employ advanced ultrasonic technology to remove processing residues, ensuring pristine cleanliness of the guide rail.
Rust-Proof Packaging: Secure the guide rail in vacuum-sealed packages or apply anti-rust oil to shield against corrosion during transit and storage, preserving quality.
Process Stability: Diligently monitor grinding parameters (including feed rate, grinding wheel grain size) and heat treatment temperature curves to ensure consistent quality and reliability.
