What is CNC Knurling?
CNC knurling is a precision machining process used to create patterned, textured surfaces on cylindrical parts. Using a knurling tool on a CNC lathe, the process forms a series of straight, angled, or diamond-shaped ridges on metals such as stainless steel, brass, aluminum, and alloy steel. Knurling is commonly applied to enhance grip, improve handling, and add a decorative or functional surface to components like shafts, knobs, fasteners, and tool handles.
Main Features of CNC Knurling
Precision Surface Texture – Creates uniform patterns (diamond, straight, or cross-lines) with tight tolerances and consistent surface finish.
Enhanced Grip & Anti-Slip Performance – Ideal for parts that require better manual control, torque, or friction.
High Durability – Cold-forming process strengthens the outer surface without removing material.
Wide Material Compatibility – Effective on carbon steel, stainless steel, brass, aluminum, and copper alloys.
Custom Pitch & Pattern Options – Available in different pitch sizes (fine, medium, coarse) to match functional or aesthetic requirements.
Suitable for Mass Production – CNC automation provides repeatability and fast cycle times for large batch manufacturing.

Finitions de surface pour le roulage CNC
Nous proposons des finitions pour l'esthétique et la performance : anodisation, polissage, sablage, revêtements et traitement thermique. Trouvons celle qui convient !
Tel que usiné
Cette finition usinée est rugueuse et présente des marques d'outils, représentant la forme la plus basique de traitement de surface sans finition ni polissage supplémentaires.
Anodisation
"Il crée une couche d'oxyde protectrice sur l'aluminium, augmentant la résistance à la corrosion et la dureté, et permettant la teinture pour améliorer l'apparence."
Polissage
"Le polissage lisse les surfaces à un haut éclat, améliorant l'apparence et réduisant la rugosité tout en offrant une certaine protection contre la corrosion."
Finition Brossée
"Une finition brossée présente de fines lignes parallèles pour un aspect texturé, améliorant la prise et réduisant les empreintes digitales."
Sablage
Le sablage utilise de l'air à haute pression et des particules abrasives pour nettoyer ou texturer les surfaces, améliorant l'adhérence des revêtements.
Électropolissage
L'électropolissage est un processus électrochimique qui lisse et éclaircit les surfaces métalliques, éliminant les imperfections et améliorant la résistance à la corrosion.
