Product Description

Experience the meticulously crafted production process from Zhejiang Cncd Transmission Equipment Co., Ltd., showcasing our state-of-the-art High-Quality Linear Rail Guide EGW20 with its reliable guide block. Witness the precision and dedication in each step of our CNCD factory's process to produce high-precision linear guides.

Material Selection: We meticulously choose only the finest high carbon steel, alloy steels like GCr15, SUJ2, or stainless steel, ensuring unparalleled durability and strength.
Pretreatment: Through forging or rolling, we expertly remove internal defects, while annealing significantly enhances cutting processability, preparing the steel for further transformation.
Shaping: Precision is key as we employ advanced milling machines and planers to initially process the reference surface, grooves, and mounting holes, leaving room for fine-tuned finishing.
Stress Relief Annealing: Our meticulous stress relief annealing process effectively eliminates internal stresses from the rough processing stage, ensuring stability in subsequent manufacturing phases.
Quenching and Tempering: Elevate the surface hardness of our guide rail to HRC58-62, significantly boosting wear resistance while tempering alleviates brittleness, ensuring long-lasting durability.
Cryogenic Treatment: Our cutting-edge cryogenic treatment further stabilizes the material structure, reducing residual austenite and enhancing dimensional precision.
Precision Grinding: Utilizing CNC surface and guide rail grinders, we achieve remarkable straightness (≤3μm/m), parallelism, and exceptional surface roughness (Ra≤0.4μm) on reference surfaces and raceways.
Employ coordinate grinders to skillfully process precision holes, ensuring perfect alignment and functionality.
Superfinishing: Through advanced polishing or superfinishing techniques, we achieve a remarkable raceway surface roughness (Ra≤0.1μm), minimizing friction for smooth operation.
Plating or Coating: Enhance wear and rust resistance with options like hard chrome plating (5-10μm thick) or advanced nitriding treatment.
Anti-corrosion Treatment: To protect the non-working surfaces, we apply blackening, phosphating, or spray a protective layer, shielding against corrosion.
Slider Processing: Each slider undergoes precision milling and grinding in its inner cavity to guarantee a perfect match with the guide rail, ensuring seamless movement.
Rolling Element Preparation: Our steel balls or rollers are ground and graded with precision, adhering to a diameter tolerance of ≤0.5μm for flawlessly smooth movement.
Pre-assembly: We temporarily assemble the slider and guide rail, testing for optimal sliding resistance and ensuring silky smoothness.
Clearance Adjustment: Achieving micrometer-level precision, we fine-tune the gap between guide rail and slider by adjusting the preload using techniques like interference fit or spring structures.
Lubrication System Integration: Optimize performance by incorporating grease applications or installing sophisticated automatic lubrication devices.
Geometric Accuracy Detection: By utilizing laser interferometers and CMM, we precisely measure straightness, parallelism, and verticality, ensuring geometrical excellence.
Employ a profilometer to meticulously analyze the raceway's shape accuracy, ensuring absolute precision.
Load Test: Rigorously verify the guide's ability to withstand deformations under rated dynamic and static loads, ensuring reliability.
Life Test: Through simulated long-term operations, we meticulously evaluate the wear rate, assuring enduring performance over time.
Noise and Vibration Test: To guarantee smooth operation, we meticulously ensure noise levels remain at or below 50dB.
Ultrasonic Cleaning: Our ultrasonic cleaning process efficiently removes all processing residues, maintaining the pristine cleanliness of the guide rail.
Rust-proof Packaging: To prevent corrosion during transit and storage, we expertly vacuum seal or apply anti-rust oil to each product.
Process Stability: With stringent monitoring of grinding parameters, such as feed rate and grinding wheel grain size, alongside precise heat treatment temperature control, we consistently ensure process integrity.
