What is CNC Milling?
CNC milling is a subtractive manufacturing process that uses computer-controlled machines to remove material from a workpiece. Rotating cutting tools create precise features like slots, holes, threads, and complex contours. At XTJ, we provide 3-axis, 4-axis, and 5-axis CNC milling to produce parts ranging from simple flat surfaces to intricate 3D geometries, ensuring versatility for your designs.
Types of CNC Milling Operations at XTJ
We offer a range of CNC milling techniques to suit different project requirements:
Face Milling
Creates flat surfaces and smooth finishes, ideal for large, even areas.
End Milling
Produces slots, pockets, and contours using the side and end of the tool.
Slot Milling
Cuts narrow channels or slots into the workpiece for functional or aesthetic purposes.
Profile Milling
Shapes the outer contours of a part, often used for complex geometries.
Thread Milling
Machines internal and external threads with precision for fasteners and fittings.
Angular Milling
Creates angled features like chamfers or dovetails for specialized components.
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)
Characteristics: Lightweight, good thermal conductivity, easy to machine, chips break easily. May cause tool sticking; requires proper cooling and lubrication. Suitable for high-speed milling.
Steel (e.g., stainless, carbon)
Characteristics: High hardness, wear-resistant, but generates high cutting forces and heat during machining. Requires low-speed milling with hard tools (e.g., carbide). Stainless steel may exhibit work hardening.
Titanium
Characteristics: High strength, low thermal conductivity, heat concentrates during machining, causing tool wear. Requires low-speed cutting, high-performance tools, and sufficient cooling.
Brass
Characteristics: Soft and easy to machine, good machinability, chips break easily, high surface finish. Suitable for high-speed milling, generates less heat.
Copper
Characteristics: High thermal conductivity, ductile, prone to tool sticking during machining. Requires sharp tools and proper lubrication. Chips may be long, so chip removal is important.
ABS
Characteristics: Good toughness, easy to machine, but prone to softening from heat. Requires controlled cutting speed and cooling to avoid melting or burrs.
POM (Polyoxymethylene)
Characteristics: Moderate hardness, wear-resistant, self-lubricating, stable during machining, good surface finish. Be cautious of thermal deformation.
PEEK
Characteristics: High temperature resistance, chemical resistance, high hardness. Requires hard tools, generates high cutting forces, and needs temperature control to prevent deformation.
Polycarbonate
Characteristics: Transparent, high toughness, but prone to stress cracking. Requires low-speed cutting to avoid overheating, and sharp tools are necessary.
Nylon
Characteristics: High toughness, wear-resistant, but hygroscopic and prone to deformation during machining. Requires controlled cutting speed, suitable for low-speed milling.
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.
Fiberglass
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.
