CNC Machining

CNC Machining Services

  CNC machining is suitable for plastic and metal parts and can be used to make from one single prototype to up to 50000 parts.

A wide variety of materials can be machined, including mild and stainless steel, aluminum, magnesium, zinc, brass and many plastics.

  We also offer the production of precision-machined components.  Our precision engineering department offers milling, turning, CNC engineering, surface

grinding, wire erosion, EDM spark erosion and more. All of your projects will be discussed carefully and checked before production starts. During and

after production the parts will be 100% inspected and we can provide original certificates for all materials used in the project as well.

Overview: What’s CNC Machining?

What is CNC machining?

CNC machining is a manufacturing technique for removing material. It uses sharp cutting tools that come in a variety of shapes and sizes and are precisely controlled by a computer. CNC stands for Computer Numerical Control.

How CNC machining works

CNC machining begins with a computer on which designers prepare a part using CAD (computer-aided design) software. This digital part is then converted into a format that can be recognized by a CNC machine.

The instructions are sent to the CNC machine in the form of “G-code,” after which the machine can begin cutting.

Most CNC machines have a “work table” and a workpiece holder to hold a block of material – called a “workpiece” – in position. Depending on the type of machine, the work table may or may not move.

When machining begins, the cutting tool comes into contact with the workpiece and cuts away layers of material. The tool and/or workpiece is moved and/or rotated quickly according to the instructions of the G-code so that the cuts are made in exactly the right places until the part is finished.

Different types of CNC machine

CNC machines include CNC mills, CNC lathes (or lathes), CNC routers, and electrical discharge machines (EDM).

CNC mills have rotating cutting tools that are moved to different areas of the workpiece to make cuts. CNC lathes work in reverse, rotating the workpiece against a stationary cutting tool, and are used to produce cylindrical parts.

CNC mills are similar to CNC routers, but have less power and cannot cut the hardest materials. However, they can be faster than CNC mills.

EDM uses electrical discharges (sparks) instead of a sharp cutting tool to cut material. There is no physical contact between the tool and the workpiece.

CNC machines are often defined by the number of axes they have. More axes mean they can move the tool and/or workpiece a greater number of ways, providing greater cutting flexibility and the ability to produce more complex parts in less time.

CNC Materials

CNC Finished

As-Machined: The most popular and cost efficient way for inner functional components. Fine and even tool path is also good for aspect parts.

Bead Blasted: The part is left with a matt appearance. Range of 120 to 320 beads allows us to create different roughness to the surface.

Anodized: Type II creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and blue are most common—and is usually associated with low silicone element series of aluminum. Type III is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.

Powder Coat: This is a process where powdered paint is sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic

CNC Machining FAQ

Why choose CNC machining?

CNC machining is a fast, accurate and versatile solution for producing plastic and metal parts for end users in any quantity without having to invest in heavy tooling or expensive setups. No matter how simple or complex the parts.

What materials can be used with CNC machining?

There’s a wide range of materials that can be used in CNC machining – you can use such as aluminum, steel, brass, copper, titanium, as well as rigid plastics. Reach out to learn more about the types of materials that could be used.

Can I get tight tolerances CNC parts from Xin Tian Jian?

Xin Tian Jian is known as one of the best CNC machining companies in China in terms of quality, speed, and customer service. With high-quality CNC machines, we can easily achieve +/- 0.02mm of tolerance and can even get within +/- 0.01mm. But keep in mind that it can have an impact on the cost.
