Product Description

The following CNCD factory's meticulous production process for our high-precision linear guides offers unparalleled quality and reliability, ensuring peak performance in your applications:

Material selection: We begin with the finest high carbon steel, alloy steel (such as GCr15, SUJ2), or stainless steel, carefully selected for their outstanding strength and durability.
Pretreatment: Our advanced forging or rolling processes eliminate internal defects, supplemented by annealing to enhance cutting processability, setting the stage for unmatched precision.
Shaping: Utilizing state-of-the-art milling machines or planers, we expertly shape the guide rail’s reference surface, grooves, and mounting holes, allowing for precise fine processing later on.
Stress relief annealing: We conduct stress relief annealing to meticulously eliminate internal stress from rough processing, preventing deformation and ensuring stability.
Quenching and tempering: By elevating the guide rail's surface hardness (up to HRC58-62), we significantly enhance wear resistance, and tempering reduces brittleness for long-lasting performance.
Cryogenic treatment: Our cryogenic treatment further stabilizes the molecular structure, reducing residual austenite and boosting dimensional stability for precision you can trust.
Precision grinding: With precision CNC surface grinders and guide rail grinders, we achieve impeccable straightness (≤3μm/m), parallelism, and refined surface roughness (Ra≤0.4μm).
Our skilled use of coordinate grinders ensures the precision processing of holes, reflecting our commitment to excellence.
Superfinishing: Through sophisticated polishing and superfinishing, we reduce raceway surface roughness (Ra≤0.1μm), minimizing friction and optimizing performance.
Plating or coating: Treatments such as hard chrome plating (5-10μm thickness) or nitriding significantly enhance wear and rust resistance, extending the lifespan of our product.
Anti-corrosion treatment: We protect non-working surfaces with blackening, phosphate, or a protective spray layer, ensuring long-term durability and resistance to corrosion.
Slider processing: Precision milling and grinding of the slider’s inner cavity ensure perfect matching accuracy with the guide rail, achieving seamless integration.
Rolling element preparation: Steel balls or rollers are meticulously ground and graded with a diameter tolerance of ≤0.5μm, guaranteeing smooth, frictionless movement.
Pre-assembly: We temporarily assemble sliders and guide rails to rigorously test sliding resistance and smoothness, assuring flawless operation.
Clearance adjustment: We expertly control the micrometer-level gap between guide rail and slider by adjusting preload (using interference fit or spring structure), optimizing alignment and performance.
Lubrication system integration: Grease is added or an automatic lubrication device is installed, ensuring consistent lubrication and reducing wear over time.
Geometric accuracy detection: Using laser interferometers and CMM, we meticulously verify straightness, parallelism, and verticality, ensuring precision and reliability.
Our profilometer analyzes raceway shape accuracy, underpinning our commitment to delivering geometrically perfect products.
Load test: Our rigorous load testing verifies guide rail deformation under rated dynamic/static loads, confirming strength and reliability under pressure.
Life test: Simulating long-term operation conditions, we evaluate wear rate, ensuring our products exceed lifespan expectations.
Noise and vibration test: We guarantee whisper-quiet operation with noise levels maintained at or below 50dB, ensuring a smooth, serene user experience.
Ultrasonic cleaning: We remove all processing residues through ultrasonic cleaning, ensuring immaculate cleanliness of the guide rail for peak performance.
Rust-proof packaging: Vacuum sealing or anti-rust oil application protects against corrosion during transportation and storage, safeguarding your investment.
Process stability: We closely monitor grinding parameters (feed rate, grinding wheel grain size) and heat treatment temperature curves, ensuring consistent quality and stability throughout production.
