Product Description

Introducing the meticulous production process of high-precision linear guides at the esteemed CNCD factory:

Material selection: Opt for premium-grade high carbon steel, robust alloy steel (like GCr15, SUJ2), or resilient stainless steel.
Pretreatment: Forge or roll the steel to eradicate internal defects and enhance cutting processability through expert annealing techniques.
Shaping: Employ advanced milling machines or planers to preliminarily craft the reference surface, grooves, and mounting holes of the guide rail, ensuring a fine processing allowance.
Stress relief annealing: This crucial step eliminates the internal stress from rough processing, safeguarding against potential deformation.
Quenching and tempering: Elevate surface hardness of the guide rail (typically achieving HRC58-62) to boost wear resistance; tempering skillfully reduces brittleness.
Cryogenic treatment: Further stabilize the structure, minimize residual austenite, and enhance dimensional stability for superior performance.
Precision grinding: Utilize state-of-the-art CNC surface and guide rail grinders to ensure impeccable straightness (usually ≤3μm/m), parallelism, and surface roughness (Ra≤0.4μm).
Use high-precision coordinate grinders to meticulously process precision holes.
Superfinishing: Achieve minimal surface roughness on the raceway (Ra≤0.1μm) through advanced polishing or superfinishing, significantly reducing friction.
Plating or coating: Apply techniques such as robust hard chrome plating (thickness 5-10μm) or nitriding to fortify wear resistance and corrosion resistance.
Anti-corrosion treatment: Employ blackening, phosphating, or protective layering on non-working surfaces for optimal corrosion prevention.
Slider processing: Precision milling and grinding of the slider's inner cavity ensure exact matching accuracy with the guide rail.
Rolling element preparation: Meticulously grind and grade steel balls or rollers with a diameter tolerance of ≤0.5μm to assure seamless movement.
Pre-assembly: Conduct temporary assembly of the slider and guide rail to evaluate sliding resistance and smoothness meticulously.
Clearance adjustment: Precisely control the micrometer-level gap between guide rail and slider by expertly adjusting preload (via interference fit or spring structure).
Lubrication system integration: Integrate grease or install an efficient automatic lubrication device for seamless operation.
Geometric accuracy detection: Employ laser interferometers and coordinate measuring machines (CMM) to meticulously check straightness, parallelism, verticality, etc.
Profilometer analyzes the shape accuracy of the raceway with precision.
Load test: Rigorously verify deformation under the rated dynamic/static load to ensure durability.
Life test: Simulate extended operation to thoroughly evaluate wear rate and longevity.
Noise and vibration test: Guarantee smooth, quiet operation with noise levels meticulously controlled to ≤50dB.
Ultrasonic cleaning: Meticulously remove processing residues, ensuring pristine cleanliness of the guide rail.
Rust-proof packaging: Employ vacuum sealing or apply anti-rust oil to prevent corrosion during transit and storage.
Process stability: Diligently monitor grinding parameters (like feed rate, grinding wheel grain size) and heat treatment temperature curve for unwavering process stability.
