Materials and Surface Finishes Supported by XTJ Machining
Varies by material type, generally high hardness. Tool selection and cutting parameters should be based on specific composition, with attention to wear resistance and thermal stability.

Aluminum (e.g., 6061, 7075)
Caractéristiques : Léger, bonne conductivité thermique, facile à usiner, les copeaux se cassent facilement. Peut provoquer un collage de l'outil ; nécessite un refroidissement et une lubrification appropriés. Convient pour le fraisage à haute vitesse.

Steel (e.g., stainless, carbon)
Caractéristiques : Haute dureté, résistante à l'usure, mais génère des forces de coupe et de la chaleur élevées lors de l'usinage. Nécessite un fraisage à basse vitesse avec des outils durs (par exemple, carbure). L'acier inoxydable peut présenter un durcissement en travail.

Titane
Caractéristiques : Haute résistance, faible conductivité thermique, la chaleur se concentre lors de l'usinage, provoquant l'usure de l'outil. Nécessite une coupe à basse vitesse, des outils haute performance et un refroidissement adéquat.

Laiton
Caractéristiques : Doux et facile à usiner, bonne machinabilité, les copeaux se cassent facilement, finition de surface élevée. Convient pour le fraisage à haute vitesse, génère moins de chaleur.

Cuivre
Caractéristiques : Haute conductivité thermique, ductile, sujet à l'adhérence de l'outil lors de l'usinage. Nécessite des outils tranchants et une lubrification appropriée. Les copeaux peuvent être longs, donc l'élimination des copeaux est importante.

ABS
Caractéristiques : Bonne ténacité, facile à usiner, mais susceptible de ramollissement par la chaleur. Nécessite une vitesse de coupe contrôlée et un refroidissement pour éviter la fusion ou les bavures.

POM (Polyoxyméthylène)
Caractéristiques : Hardness modérée, résistant à l'usure, auto-lubrifiant, stable lors de l'usinage, bonne finition de surface. Faire attention à la déformation thermique.

PEEK
Caractéristiques : Résistance à haute température, résistance chimique, dureté élevée. Nécessite des outils durs, génère des forces de coupe importantes et nécessite un contrôle de la température pour éviter la déformation.

Polycarbonate
Caractéristiques : Transparent, haute ténacité, mais sujet à la fissuration sous contrainte. Nécessite une coupe à faible vitesse pour éviter la surchauffe, et des outils tranchants sont indispensables.

Nylon
Caractéristiques : Haute ténacité, résistant à l'usure, mais hygroscopique et susceptible de déformation lors de l'usinage. Nécessite une vitesse de coupe contrôlée, adapté au fraisage à basse vitesse.

Carbon Fiber
Characteristics: High strength, lightweight, but very hard. Prone to delamination or burrs during machining. Requires diamond or carbide tools, and dust protection is necessary.

Fibre de verre
Characteristics: High hardness, corrosion-resistant, but abrasive to tools and generates dust during machining. Requires efficient dust extraction and hard tools.
Elevate Your Parts with Advanced Surface Finishing
Enhance the durability, functionality, and aesthetics of your components with XTJ’s range of surface finishing options. Each process is tailored to meet specific performance and design requirements, ensuring your parts not only perform exceptionally but also look their best.

Durable and Versatile Coating for Long-Lasting Protection
Powder coating applies a dry powder—typically a mix of resin and pigment—electrostatically to the part, which is then cured under heat to form a tough, protective layer. This finish is known for its durability and resistance to chipping, scratching, and corrosion.

Uniform Matte Finish for Enhanced Aesthetics
Bead blasting uses small glass beads propelled at high pressure to create a consistent, non-reflective matte finish on the surface of parts. This process removes surface imperfections and provides a clean, uniform texture.

Mirror-Like Finish for Premium Applications
Polishing involves mechanically smoothing the surface of a part to achieve a high-gloss, mirror-like finish. This process enhances both the visual appeal and the tactile quality of the component.

Enhanced Corrosion Resistance for Stainless Steel
Passivation is a chemical treatment that removes free iron from the surface of stainless steel parts, forming a passive oxide layer that significantly improves corrosion resistance.
What is CNC Turning?
CNC turning is a subtractive process where a cutting tool moves along a rotating workpiece to create cylindrical parts. At XTJ, we utilize 2-axis, 3-axis, and multi-axis CNC turning to produce components with features like threads, grooves, and tapers, offering flexibility for simple to complex designs.
