CNC stands for “Computer Numerical Control” which is a generic term for machines that are controlled by a computer or controller. CNC machines are usually made of steel, aluminum, stainless steel, and brass. They can cut materials with tight tolerances to create parts with top-quality results.

One of the most common materials that CNC machines work on is metal. There are many uses for CNC machines in the metal industry like cutting sheets of metals like aluminum or steel or creating individual pieces like urns and urn lids out of brass.

CNC machinists who work in metal shops will use these tools to make custom pieces based on drawings provided by engineers and designers. Other industries where CNC machines are used include construction (cutting lumber), aerospace.

Can you use a CNC machine for metal?

Yes, a CNC machine can be used for metal. It is primarily used for cutting and shaping metal sheets. You can also use it for die-casting and welding.

A CNC machine is a computer-controlled cutting device that makes accurate cuts on a metal sheet without any physical contact with the material. A CNC machine has three axes of motion: it moves up and down, left to right, and forwards or backwards. It uses these axes to move the cutting tool at the desired speed and depth to cut through the metal material.

It is important to know which metals can be CNC machined. Different metal types require different cutting processes. This is because of how they are structured on the atomic level. For instance, aluminum is brittle and will shatter if not cut carefully. On the other hand, high-carbon steel has a tough surface that makes it difficult to cut with a laser or water jet.

The list below contains some metals that are commonly used for CNC machining:


  • Aluminum
  • – Brass
  • – Copper
  • – Gold
  • – Iron
  • – Steel
  • Titanium
  • Magnesium

Metal CNC machines are used in various industries such as aerospace, automotive, shipbuilding industries. These machines are relatively more affordable than other industrial machinery because they have become one of the most popular fabrication tools in recent years.

A metal CNC machine is an industrial machine that shapes and cuts material by using computer numerically controlled (CNC) tools.

The price for a metal CNC machine can vary depending on the size and features of the machine, but it typically ranges from $5,000 to $500,000.  source:

The Important Things You Should Know

Metal CNC Machining: Questions & Answers

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 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.

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.

Usually we book the shipment with your appointed forwarder, or can ship to your warehouse with our shipment company

We also working with DHL/FEDEX/UPS for  long term relationship to have competitive express shipment with fast delivery.

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 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.

3Q Machining 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.
