Product Description

Discover the meticulous craftsmanship behind the CNCD factory's high-precision linear guides production process, a testament to precision engineering.

Material selection is paramount: Opt for premium high carbon steel, alloy steel (like GCr15, SUJ2), or stainless steel to ensure durability and strength.
Pretreatment involves forging or rolling the steel to eliminate internal defects, followed by annealing to enhance cutting processability, ensuring the core integrity.
Shaping stage employs advanced milling machines or planers to meticulously craft the reference surface, grooves, and mounting holes of the guide rail, preserving a fine processing allowance.
Stress relief annealing is crucial for eliminating internal stress from rough processing, safeguarding against future deformation, and ensuring structural integrity.
Through quenching and tempering, the guide rail's surface hardness is elevated (typically reaching HRC58-62), significantly boosting wear resistance while tempering reduces brittleness.
Cryogenic treatment further stabilizes the material structure, diminishes residual austenite, and enhances dimensional stability for long-term reliability.
Precision grinding with CNC surface grinders ensures the guide rail's reference surface and raceway maintain exceptional straightness (≤3μm/m), parallelism, and surface roughness (Ra≤0.4μm).
Coordinate grinders are employed for the meticulous processing of precision holes, ensuring exacting standards are met.
Superfinishing techniques polish the raceway surface (Ra≤0.1μm) to reduce friction, enhancing the guide's operational smoothness and longevity.
Plating or coating, including options like hard chrome plating (5-10μm thick) or nitriding, is applied to bolster wear resistance and fend off rust.
Anti-corrosion treatments such as blackening, phosphating, or protective layer spraying are applied to non-working surfaces to uphold integrity against rust.
Slider processing involves precise milling and grinding of the slider's inner cavity to ensure perfect matching accuracy with the guide rail.
Rolling elements, whether steel balls or rollers, are ground and graded with a fine diameter tolerance (≤0.5μm) for seamless motion.
Pre-assembly involves an initial fitting of the slider and guide rail to assess sliding resistance and operational smoothness, ensuring optimal functionality.
Clearance adjustment fine-tunes the micrometer-level gap between the guide rail and slider through preload adjustments, like interference fit or spring structures.
Integrating a lubrication system, whether by adding grease or automatic lubrication devices, ensures continued smooth operation and reduced maintenance.
Geometric accuracy detection employs laser interferometers and coordinate measuring machines to verify straightness, parallelism, and verticality, guaranteeing precision alignment.
A profilometer scrutinizes the raceway shape accuracy, maintaining stringent quality standards.
Load tests validate deformation under rated dynamic and static loads, ensuring the guide system's reliability and robustness.
Life tests simulate prolonged operation to evaluate wear rates, providing insights into the system's durability over time.
Noise and vibration tests confirm smooth operation, maintaining operational noise levels (such as ≤50dB) for a quieter performance.
Ultrasonic cleaning meticulously removes processing residues, ensuring pristine cleanliness of the guide rail for optimal performance.
Rust-proof packaging, such as vacuum sealing or anti-rust oil application, safeguards against corrosion during transport and storage, preserving product integrity.
Process stability is maintained by meticulously monitoring grinding parameters (e.g., feed rate, grinding wheel grain size) and heat treatment temperature curves, ensuring consistent quality.
