Product Description

Explore the meticulous craftsmanship and advanced production techniques at CNCD factory that we employ in crafting high-precision linear guides.

Our material selection is uncompromising, utilizing only the finest high carbon steel, renowned alloy steels like GCr15, SUJ2, or superior stainless steel.
Through skilled pretreatment, we forge or roll the steel to eradicate internal defects, enhancing the steel's machinability with precision annealing.
During the shaping stage, we meticulously use a milling machine or planer to process the reference surface, grooves, and mounting holes of the guide rail, allowing for a precise finishing touch.
Stress relief annealing is pivotal in our process, eliminating rough processing-induced stress to ensure perfect subsequent shaping.
Our quenching and tempering process elevates the guide rail's surface hardness to an impressive HRC58-62, significantly boosting wear resistance while tempering minimizes brittleness.
The cryogenic treatment stabilizes the material structure, effectively reducing residual austenite and promoting unparalleled dimensional stability.
Precision grinding is executed with CNC surface and guide rail grinders, achieving impeccable straightness (typically ≤3μm/m), parallelism, and a superior surface finish (Ra≤0.4μm).
Precision holes are crafted with unrivaled accuracy using state-of-the-art coordinate grinders.
Superfinishing is the final flourish, polishing the raceway to a mirror-like finish (Ra≤0.1μm), optimizing smoothness and minimizing friction.
To further fortify our product, we apply hard chrome plating or nitriding, enhancing both wear and rust resistance.
The anti-corrosion treatment involves blackening, phosphating, or spraying a protective layer over non-working surfaces, extending longevity.
For slider processing, we employ precision milling and grinding of the slider's inner cavity, ensuring a seamless match with the guide rail.
Our rolling element preparation is meticulous; steel balls or rollers are expertly ground and graded for precision, ensuring ultra-smooth movement with a diameter tolerance of ≤0.5μm.
In pre-assembly, the slider and guide rail are temporarily joined to evaluate and perfect sliding resistance and smoothness.
The clearance adjustment process refines the micrometer-level gap between the guide rail and slider by fine-tuning the preload, using structures like interference fit or springs.
Our lubrication system integration is thorough, incorporating grease or advanced automatic lubrication devices for optimal performance.
Geometric accuracy detection employs laser interferometers and CMMs to rigorously test straightness, parallelism, and verticality, ensuring precision.
A profilometer meticulously analyzes the raceway's shape accuracy, affirming our commitment to exactness.
Load tests verify deformation under rated dynamic/static loads, guaranteeing reliability and resilience.
Life tests simulate extended operation, diligently assessing wear rates to ensure enduring performance.
Noise and vibration tests are conducted to ensure whisper-quiet operation, with noise levels kept at a pleasant ≤50dB.
Ultrasonic cleaning meticulously removes processing residues, certifying the pristine cleanliness of each guide rail.
Finally, our rust-proof packaging uses vacuum seals or anti-rust oil applications to prevent corrosion during transit and storage.
We uphold process stability by strictly monitoring grinding parameters like feed rate and grinding wheel grain size, alongside heat treatment temperature curves, ensuring consistent excellence.
