Product Description

Explore the meticulous production process at Zhejiang Cncd Transmission Equipment Co., Ltd., where precision craftsmanship brings our high-precision linear guides to life:

Material Selection: Opt for superior high carbon steel, alloy steel (such as GCr15, SUJ2), or stainless steel, ensuring unmatched durability and performance.
Pretreatment: Enhance steel integrity with precision forging or rolling to eliminate internal defects, followed by annealing to improve cutting efficiency.
Shaping: Employ advanced milling machines or planers to expertly craft the reference surface, grooves, and mounting holes of the guide rail, setting the stage with a precision allowance.
Stress Relief Annealing: Relieve internal stresses from rough processing, thwarting potential deformation in future stages.
Quenching and Tempering: Elevate the guide rail's surface hardness to HRC58-62, fortifying wear resistance while tempering diminishes brittleness for optimal resilience.
Cryogenic Treatment: Perfect the internal structure, minimizing residual austenite and enhancing dimensional stability for consistent performance.
Precision Grinding: Utilize CNC surface grinders and guide rail grinders to achieve unparalleled straightness (≤3μm/m), parallelism, and surface finish (Ra≤0.4μm).
Coordinate Grinders: Masterfully process precision holes with our state-of-the-art grinders for exceptional accuracy.
Superfinishing: Through skilled polishing or superfinishing, achieve an extraordinary surface roughness of the raceway (Ra≤0.1μm), reducing friction dramatically.
Plating or Coating: Apply robust hard chrome plating (5-10μm thick) or opt for nitriding treatment to significantly boost wear and rust resistance.
Anti-Corrosion Treatment: Safeguard non-working surfaces with protective blackening, phosphating, or spraying techniques.
Slider Processing: Achieve precision in milling and grinding the slider's inner cavity to ensure impeccable matching accuracy with the guide rail.
Rolling Element Preparation: Meticulously grind and grade steel balls or rollers, maintaining a diameter tolerance of ≤0.5μm for seamless motion.
Pre-Assembly: Conduct a provisional assembly of the slider and guide rail to assess and refine sliding resistance and smoothness.
Clearance Adjustment: Precisely regulate the micrometer-level gap between the guide rail and slider by fine-tuning the preload for optimal performance.
Lubrication System Integration: Enhance longevity with grease or an automatic lubrication device for consistent, frictionless operation.
Geometric Accuracy Detection: Employ laser interferometers and coordinate measuring machines (CMM) to scrutinize straightness, parallelism, and verticality with exactitude.
Profilometer Analysis: Meticulously analyze the raceway's shape accuracy, ensuring flawless alignment and performance.
Load Test: Rigorously verify deformation under rated dynamic and static loads to guarantee robust, reliable performance.
Life Test: Simulate prolonged operation scenarios to meticulously evaluate the wear rate, ensuring durability and reliability.
Noise and Vibration Test: Achieve smooth, whisper-quiet operation with noise levels carefully maintained at ≤50dB.
Ultrasonic Cleaning: Thoroughly eliminate processing residues, ensuring the highest levels of cleanliness for the guide rail's optimal function.
Rust-Proof Packaging: Securely vacuum seal or apply protective anti-rust oil, safeguarding against corrosion during transport and storage.
Process Stability: Diligently monitor grinding parameters and heat treatment temperature curves to ensure unwavering process consistency and quality.
