3 Axis CNC Milling

A profitable and efficient solution to your CNC milling needs! We ensure the machining of parts with complex geometrical shapes, including undercut features, threaded holes, sharp edges, and planar profiles. Complete multiple operations through effective integration with an automatic tool changer. We can also design 3-axis milling centers to meet the unique requirements of each client.

4 Axis CNC Milling

Get more complex CNC milled parts with our 4-axis CNC milling. We consistently produce precise and accurate results, with greater control and more flexibility, even with complex shapes. Ensure cost-effective machining of angled features that are rather impossible with 3-axis machines. With more power, greater control, and higher precision, 4-axis milling is your ideal solution.


5 Axis CNC Milling

Machine complex custom CNC milled parts with a single setup. Our 5-axis CNC milling machines save time, improve efficiency, and reduce cost, ensuring that you meet market demands faster and cost-effectively. We can reach higher cutting speeds without excessive pressure on the cutter. Get rapid prototypes and low-volume production parts with better surface finishes.

Smooth, matte finish.

Bead Blasting

Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.

ABS, Aluminum, Brass, Stainless Steel, Steel



Powder Coating

Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.

Aluminum, Stainless Steel, Steel

Black, any RAL code or Pantone number


Gloss or semi-gloss


Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.

Aluminum, steel, stainless steel


Smooth, glossy finish


Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.

Aluminum, Brass, Stainless Steel, Steel




Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.

Our CNC Milling for Various Industrial Applications

CNC milling parts have seen significant use in a variety of industries. With our advanced facilities and refined CNC milling technologies, we can create precision and quality CNC milled parts in a rapid manner.

Our CNC Milling for Various Industrial Applications

JTC CNC works with vertical, horizontal, and multi-axis milling machines. The vertical milling machine is highly accurate equipment that carries out 3-axis milling, suitable for vertical surfaces and angular shapes.

Our horizontal milling machines perform 4-axis milling and are suitable for heavy milling operations. Our multi-axis milling machines can move along different axes and cut at various angles. They include 2-, 3-, 4-, and 5-axis CNC milling machines.

Yes, you can combine both manufacturing processes to reinforce your custom parts. Printed parts can be milled to achieve dimensions with tight tolerances or to meet surface quality requirements. Intelligently combining these two methods can ensure faster manufacturing, less waste, and lower costs. It even achieves higher accuracy and precision, repeatability, and sustainable production.

At RapidDirect, we can produce highly complex and intricate rapid prototypes and low-volume production parts. The CNC milling process is suitable for a wide selection of materials for various applications. Our CNC milling service can achieve standard tolerances of +/- 0.05mm. However, tighter tolerances of up to +/- 0.01mm are also possible.

The major difference between CNC milling and CNC lathe is in their machining process. CNC milling involves rotating the cutting tools against a stationary bar stock or workpiece. In contrast, a CNC lather works by rotating the bar stock or workpiece against a stationary tool. CNC milling is more suitable for machining irregular and flat surfaces, while CNC lathes work best for cylindrical or conical parts.
