3 Axis CNC Milling

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

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.

CNC Materials

CNC Turning Aluminum


Aluminum is a highly ductile metal, making it easy to machine. The material has a good strength-to-weight ratio and is available in many types for a range of applications.



Copper displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.



Brass has desirable properties for a number of applications. It is low friction, has excellent electrical conductivity and has a golden (brass) appearance.

Type :Copper 260,Copper 360,

Stainless Steel parts

Stainless Steel

Stainless steel is the low carbon steel that offers many properties that are sought after for industrial applications. Stainless steel typically contains a minimum of 10% chromium by weight.

Type :303,304/304L,316/316L, 17-4 PH

Titanium parts


Titanium has a number of material properties that make it the ideal metal for demanding applications. These properties include excellent resistance to corrosion, chemicals and extreme temperatures. The metal also has an excellent strength-to-weight ratio.

Type :Gr1,GR2,GR5


Plastics are also very popular option for CNC machining because of its wide choices, relatively lower price, and significantly faster machining time needed. We provide all common plastics for CNC machining services.

type :POM(Delrin/Acetal),PEEK,HDPE,PET,Nylon(Polyamide),PTFE (Teflon),PVC,PP,ABS,PC,PMMA(Acrylic),ETC…



Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. A cathode is mounted to the inside of the anodizing tank; the aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized. Anodizing is, therefore, a matter of highly controlled oxidation the enhancement of a naturally occurring phenomenon.

bead blasting

bead blasting

The bead blasting process uses a blasting media – beads – under high pressure. Propelling the beads at a surface cleans, polishes, or roughens the surface to the desired finish. These beads are shot out toward the component from a high-pressure bead-blaster. When the beads hit the surface, the impact creates a uniform “dimpling” on the surface. A bead blast finish can clean corroded metal, remove cosmetic defects like textures and contaminants, and prepare a part for paint and other coatings.

Powder Coating

powder coating

Powder Coating is a dry finishing process created by an electric charge that causes a dry powder to fuse to the surface of the metal. This is then baked in a curing oven to achieve a smooth coating. It is usually used to create a hard finish that is tougher than conventional paint.


Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes. The process uses an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode. Electroplating is often applied in the electrical oxidation of anions on a solid substrate like the formation of silver chloride on silver wire to form silver chloride electrodes.


Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations).


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.

CNC milling is a machining process that utilizes computerized controls to manage the movement and operation of multi-point rotary cutting tools. As the tools rotate and move across the surface of the workpiece, they slowly remove excess material to achieve the desired shape and size.

The benefits of CNC milling include its ability to cut a wide range of materials and produce custom-designed parts much faster than conventional machining. CNC milling can be used to machine parts from a variety of materials, such as aluminum, iron, steel alloys, nickel, etc.

The CNC Milling process works by the machine reading coded instructions and then putting them into operation. It all starts with developing a 3D CAD file representing the final part. Once completed, the design is converted into a machine-readable format. CAM (Computer-Aided Manufacturing) software then exports this to a CNC machine program, usually in G-code format, which acts as the instructions, directing every move that the machine makes. This replicates the CAD design in the chosen material with high accuracy and efficiency.

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.
