Product Description

Discover the meticulous craftsmanship behind CNCD factory's creation of high-precision linear guides. Our advanced production process ensures exceptional quality at every stage.

Material selection is key: We meticulously choose from high carbon steel, alloy steel (like GCr15, SUJ2), or stainless steel to ensure durability and performance.
Pretreatment involves expertly forging or rolling the steel to eradicate internal defects, followed by annealing to enhance cuttability.
Shaping excellence: With precision milling machines or planers, we initially process reference surfaces, grooves, and mounting holes, ensuring a fine processing allowance.
Stress relief annealing: We efficiently eliminate internal stress from rough processing to maintain structural integrity and prevent deformation.
Quenching and tempering boost surface hardness (typically HRC58-62), enhancing wear resistance while tempering effectively reduces brittleness.
Cryogenic treatment stabilizes the structure, minimizes residual austenite, and significantly improves dimensional stability.
Precision grinding uses advanced CNC surface and guide rail grinders to perfect the reference surface and raceway, ensuring superb straightness (≤3μm/m) and parallelism.
Utilize coordinate grinders to meticulously craft precision holes, achieving unparalleled accuracy.
Superfinishing reduces raceway surface roughness (Ra≤0.1μm) through polishing, minimizing friction and enhancing performance.
Plating or coating options, such as hard chrome plating (5-10μm) or nitriding, offer superior wear and rust resistance.
Anti-corrosion treatments, including blackening, phosphating, or protective spray, shield the non-working surfaces.
Slider processing involves precision milling and grinding, ensuring the slider perfectly matches the guide rail.
Rolling element preparation is essential: Steel balls or rollers undergo precise grinding and grading with a diameter tolerance of ≤0.5μm for seamless operation.
Pre-assembly includes temporarily joining the slider and guide rail to assess sliding resistance and smoothness.
Clearance adjustment fine-tunes the micrometer-level gap between the guide rail and slider by adjusting preload through interference fit or spring mechanisms.
Incorporating a lubrication system, whether through grease or automatic devices, ensures optimal performance and longevity.
Geometric accuracy is meticulously verified using laser interferometers and coordinate measuring machines (CMM) for straightness, parallelism, and more.
Using a profilometer, we analyze the raceway's shape accuracy, ensuring flawless guideway performance.
Load tests confirm the guide's resilience by verifying deformation under rated dynamic and static loads.
Life testing simulates long-term operation, evaluating wear rate for durability assurance.
Noise and vibration tests ensure whisper-quiet operation, maintaining noise levels at or below 50dB.
Ultrasonic cleaning removes processing residues, guaranteeing immaculate guide rail cleanliness.
Rust-proof packaging, either through vacuum sealing or anti-rust oil application, prevents corrosion during transport and storage.
Process stability is paramount: We rigorously monitor grinding parameters and heat treatment temperature curves for consistent excellence.
