Product Description

Introducing the highly meticulous CNCD factory's production process for crafting high-precision linear guides, ensuring precision and excellence at every step.

Material Selection: Opt for premium high carbon steel, robust alloy steel (including GCr15, SUJ2), or resilient stainless steel to form the foundation of superior quality.
Pretreatment: Employ advanced forging or rolling techniques to eradicate internal imperfections, followed by annealing to enhance cutting processability.
Shaping: Utilize sophisticated milling machines or planers to meticulously process the reference surface, grooves, and mounting holes of the guide rail, maintaining allowances for fine processing.
Stress Relief Annealing: Precisely eliminate internal stresses from rough processing, safeguarding against future deformations and ensuring structural integrity.
Quenching and Tempering: Elevate the surface hardness of the guide rail to an optimal HRC58-62, bolstering wear resistance while tempering effectively reduces brittleness.
Cryogenic Treatment: Strengthen structural stability and diminish residual austenite for enhanced dimensional stability and performance longevity.
Precision Grinding: Employ CNC surface grinders and specialized guide rail grinders to achieve superior straightness, parallelism, and surface roughness, ensuring every detail meets exacting standards.
Precision Drilling: Utilize coordinate grinders for the meticulous processing of precision holes, achieving unmatched precision.
Superfinishing: Employ advanced polishing or superfinishing techniques to achieve an ultra-smooth raceway surface, reducing friction to a minimum.
Plating or Coating: Opt for hard chrome plating or nitriding treatments of 5-10μm thickness to significantly enhance wear and rust resistance.
Anti-Corrosion Treatment: Apply blackening, phosphating, or protective layer spraying on non-working surfaces for robust rust prevention.
Slider Processing: Execute precision milling and grinding within the slider's inner cavity to secure impeccable alignment and fit with the guide rail.
Rolling Element Preparation: Grind and grade steel balls or rollers to a diameter tolerance of ≤0.5μm, ensuring seamless, smooth movement.
Pre-Assembly: Conduct temporary assembly of the slider and guide rail, diligently assessing sliding resistance and smoothness.
Clearance Adjustment: Achieve micrometer-level precision in controlling the gap between the guide rail and slider by adjusting preload configurations.
Lubrication System Integration: Infuse grease or install an efficient automatic lubrication device to maintain optimal operational conditions.
Geometric Accuracy Detection: Deploy laser interferometers and CMMs to scrutinize straightness, parallelism, and verticality with unparalleled precision.
Profilometer Analysis: Conduct meticulous analysis of the raceway's shape accuracy to ensure design specifications are met.
Load Test: Rigorously verify deformation under specified dynamic and static loads, guaranteeing reliability and durability.
Life Test: Simulate extended operational conditions to carefully evaluate wear rates and ensure longevity.
Noise and Vibration Test: Assure operation smoothness with rigorous tests, ensuring noise levels remain ≤50dB.
Ultrasonic Cleaning: Thoroughly remove residuals from processing to maintain the pristine cleanliness of the guide rail.
Rust-Proof Packaging: Employ vacuum sealing or anti-rust oil applications to safeguard against corrosion during transport and storage.
Process Stability: Vigilantly monitor grinding parameters including feed rate, grinding wheel grain size, and heat treatment temperature curves to ensure consistent quality.
