CNC Milling

Compared with CNC turning, CNC milling, especially 5 axis milling can be used to create complex 3D shapes or to apply a machined surface or features to parts made both plastics and metals. The advantage of multi-axis milling machines makes CNC milling process versatile, as well as accurate and repeatable, for creating many different types of part features of complex geometries. Example include holes, curves, slots, angled shapes, and channels. Milling is also ideal for making tooling for pressure die casting and plastic injection molding.







CNC Turning

CNC lathes allow us to get high-speed turning of both plastics and metals from bar or block material. The turning process allows the production of complex external and internal geometries, including generating all kinds of threads. For any round shaped components, for example, shafts, worms, spheres, CNC turning is a more efficient method compared with CNC milling. Zigitech’s turning capability can make prototypes all the way through mass production parts.

Precision Machining


Aside from standard tolerance CNC parts such as ISO2678M or ISO2678F, Zigitech also offers high-precision CNC machining parts. With high precision milling & turning machines, we are able to catch super tight tolerance for prototype machining & production.

Using high-quality machines, tools, vises, jigs, and an on-machine, in-process inspection system, we can hit tighter tolerances than other machining shops.

In addition to our in-process QC system, we have the most experienced people working in our QC department. They are familiar with a range of inspection equipment, including laser projectors, CMMs, and 3D scanners, and can therefore ensure that all our manufactured parts meet the highest standards.

CNC Machining Materials & Finishes


If you are considering manufacturing your parts with CNC machining, it is important to know what kind of materials and finishes can be applied to your CNC machined parts. Zigitech, located in China, is not just a CNC shop; we can also apply all types of finishes to CNC prototype parts and production parts thanks to our surface finishing partners. Need custom CNC parts with a high-quality appearance? Zigitech is here to help.



CNC Machining Materials, Metals, aluminium

CNC Materials


Plastic: ABS, PC, ABS+PC, PP, PS, POM, PMMA (Acrylic), PAGF30, PCGF30, Teflon, DHPE, HDPE, PPS, PEEK.

Metal: Aluminum, Steel, Stainless Steel (17-4, Inconel 625 & 718), Magnesium, Titanium, Zinc, Brass, Bronze, Copper.

These are the most common materials for CNC prototyping and production parts. Besides that, we can work with any type of machinable plastic and metal we can purchase from the stock market.

What’s more: We are able to create a custom plastic block or bar for the material such as PA GF50, PPS GF50. To discover further plastic materials we can do, please contact our team.

CNC Finishes, As-Machined, Bead Blasted, Anodized, Powder Coat

CNC Finishes


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.







Overview: What's CNC Machining?


What is CNC machining?

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

How CNC machining works

CNC machining starts 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.

Instructions are sent to the CNC machine in the form of  “G-Code” after which the machine can start cutting.

Most CNC machines have a “worktable” and work holding device to keep a block of material — known as the “workpiece” — in place. The worktable may or may not move, depending on the style of the machine.

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

Different types of CNC machine

CNC machines include CNC mills, CNC turning machines (or lathes), CNC routers, and Electrical Discharge Machining (EDM) machines.

CNC mills have rotating cutting tools that are moved to different areas of the workpiece to make cuts and can be used to make many different pats. CNC lathes work the other way, rotating the workpiece against a stationary cutting tool, and are used to make cylindrical parts.

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

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

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








CNC Machining FAQ


Why choose CNC machining?

CNC machining is a fast, accurate and versatile solution for making end-use plastic and metal parts in any quantity, without the need for investing in hard tooling or expensive set-ups. No matter how simple or complex the parts.
