Product Description

Delve into the meticulous production process of our CNCD factory's high-precision linear guides, where precision meets excellence.

Material Selection: We meticulously choose only the finest high carbon steel, alloy steel like GCr15 and SUJ2, or stainless steel, ensuring unparalleled quality as the foundation of our guides.
Pretreatment: Through expert forging or rolling, we eliminate internal defects, coupled with annealing to enhance cutting processability, setting the stage for precision.
Shaping: Our skilled craftsmen use advanced milling machines or planers to expertly craft the reference surface, grooves, and mounting holes of the guide rail, leaving just the right allowance for fine processing.
Stress Relief Annealing: We expertly eliminate any internal stress from rough processing, ensuring our products are free from subsequent deformation and remain robust.
Quenching and Tempering: We enhance surface hardness (reaching HRC58-62), bolstering wear resistance while carefully tempering to reduce brittleness, achieving the perfect balance.
Cryogenic Treatment: By stabilizing the microstructure and reducing residual austenite, we significantly improve our guides' dimensional stability for superior performance.
Precision Grinding: Our CNC surface and guide rail grinders achieve impeccable straightness (≤3μm/m), parallelism, and surface smoothness (Ra≤0.4μm), ensuring unmatched precision.
Precision Hole Processing: Our coordinate grinders deliver accuracy in processing precision holes, vital for flawless assembly.
Superfinishing: Through polishing or superfinishing, we attain a surface roughness (Ra≤0.1μm), minimizing friction for smoother operations.
Plating or Coating: With techniques like hard chrome plating (5-10μm thick), we elevate wear and rust resistance, promising longevity in demanding environments.
Anti-Corrosion Treatment: We apply blackening, phosphating, or a protective spray to non-working surfaces, safeguarding against corrosion and extending lifespan.
Slider Processing: The inner cavity of our sliders undergoes precision milling and grinding, ensuring a perfect match with the guide rail for optimal performance.
Rolling Element Preparation: Our steel balls and rollers are meticulously ground and graded to a diameter tolerance of ≤0.5μm, guaranteeing seamless movement.
Pre-Assembly: We temporarily assemble sliders and guide rails, rigorously detecting sliding resistance and smoothness for flawless operation.
Clearance Adjustment: By adjusting the preload with precision, we control the micrometer-level gap between guide rail and slider, ensuring perfect alignment and function.
Lubrication System Integration: We incorporate grease or automatic lubrication devices, ensuring that our guides operate smoothly and with minimal maintenance.
Geometric Accuracy Detection: Using laser interferometers and CMMs, we meticulously measure straightness, parallelism, and verticality for uncompromising accuracy.
Raceway Shape Analysis: Employing profilometers, we ensure impeccable shape accuracy of the raceway, securing the guides' flawless operation.
Load Test: We rigorously verify deformation under rated dynamic/static loads, ensuring that our guides can withstand real-world demands.
Life Test: By simulating long-term operations, we evaluate wear rates, guaranteeing that our guides endure the test of time with grace.
Noise and Vibration Test: We ensure that our guides operate smoothly, maintaining noise levels below 50dB for a serene and efficient environment.
Ultrasonic Cleaning: We meticulously remove all processing residues, ensuring our guide rails are impeccably clean and ready for use.
Rust-Proof Packaging: With vacuum sealing or anti-rust oil application, we protect our products against corrosion during transit and storage, preserving their integrity.
Process Stability: We diligently monitor grinding parameters and heat treatment temperature curves, ensuring the highest standards of process stability and product excellence.
