CNC Milling

CNC Turning
CNC turning is commonly used for machining cylindrical, conical, and shaft-like structures with rotational symmetry. Its principle involves rotating the workpiece while controlling the tool feed to perform cutting operations.

CNC Drilling
CNC drilling is primarily used for machining hole structures. By controlling the axial feed of rotating cutting tools, it creates precise hole diameters and depths in metals and engineering plastics.

CNC Machining Materials
Explore a wide range of materials for CNC machining, including solutions for metal, plastic, and wood CNC machining, tailored to meet the needs of every industry and application.










Polypropylene (PP) is a versatile and robust thermoplastic that is chemically resistant, lightweight, and has a high melting point. Commonly used in automotive parts, packaging, and medical devices, it offers excellent fatigue resistance, low density, and high chemical stability for a range of applications.

Polystyrene (PS) is a clear, rigid thermoplastic known for its excellent electrical insulation properties, ease of molding, and affordability. It’s commonly used in packaging, disposable cutlery, and insulation products, offering good dimensional stability and ease of processing in various applications.

Polyvinyl chloride (PVC) is a versatile and durable thermoplastic with excellent chemical and weather resistance. It is commonly used in construction, plumbing, and electrical insulation, offering high strength, rigidity, and flame retardancy in both rigid and flexible forms.

Nylon is a strong, lightweight, and abrasion-resistant thermoplastic known for its excellent mechanical properties. Used in automotive, textiles, and industrial applications, it provides high strength, wear resistance, and stability in harsh environments.


CNC Surface Finishing
Achieve the ideal texture and durability through processes such as anodizing, electroplating, and spraying, catering to the diverse needs of various industries.

Anodizing
An electrochemical process forms a dense oxide layer that enables coloring and enhances corrosion and wear resistance.

Electroplating
Metal surfaces are coated with a layer to improve corrosion resistance, electrical conductivity, and gloss.

Spraying
Evenly sprays paint onto metal or plastic surfaces, allows flexible coloring, and enhances appearance.

Sandblasting
Abrasive particles are used to create a uniform matte texture on the surface, which is often used in pretreatment.

Polishing

Laser Engraving
Electrostatically applies powder and cures it at high temperature, available in textured, matte, or glossy finishes.

Powder Coating
Electrostatically applied powder coating with high-temperature curing, capable of producing textured, matt or high-gloss finishes.

Brushing
By drawing consistent linear patterns with sanding belts, the tactile quality and metallic appearance are enhanced.
