For novice business owners or aspiring cnc metal machining suppliers, learning the basic metal machining process is a must. The machining process involves material removal from a workpiece. Power machine tools are used to shape metal into the desired design to create metal parts or components in various applications. Also, machining can be performed on any existing part, like forging or casting.

In this post, you’ll learn more about the cnc metal machining process for your reference when choosing the best manufacturing techniques for your products, as well as in meeting your clients’ needs and preferences.

What is CNC metal machining?

CNC Metal machining is a form of a manufacturing process that is used in creating metal parts, tools, or machinery. It involves different processes to achieve the final product’s desired design, in terms of shape, hole diameter, size, texture, and finishing.

CNC stands for Computer Numerical Control. In manufacturing, CNC machining means using a computer to convert the product design into graph coordinates or numbers, controlling cutter movements. In short, CNC machining involves pre-programmed computer software that dictates the movement of manufacturing tools and pieces of machinery such as grinders, lathes, mills, and routers.

CNC machining runs pre-programmed designs in repetitive and predictable cycles. Because human operators are kept to a minimum level, this machining process is now widely used in the manufacturing sector.

What is the CNC Metal machining process?

The CNC metal machining process involves a series of processes to achieve desired product specifications, features, and benefits.

1. CNC Turning

This is a form of metal CNC machining that involves removing unwanted metal materials from rotational parts. A lathe or a turning machine can be used, which is fed into a workpiece at high rotating speeds. As already discussed above, the two types of turning are single-point cutting and multi-point cutting. Tools are used depending on the product requirements.

Turning adds precision to rotational metal part features with an existing shape, so you can always refine or add some features on metal components. Custom-designed fasteners and shafts are some examples of metal parts you can fabricate using this procedure.

2. CNC Milling

You can create symmetric metal parts, such as slots, three-dimensional surface contours, holes, and pockets. Metal tools are usually fabricated using milling. Other examples include custom-designed brackets and fasteners.

Milling cutting tools may include carbide, high-speed steel or HSS, high-speed cobalt steel, and carbon steel. The type of cutting tool material you’ll need will depend on the cutter’s properties, such as resistance to wear, toughness, and hardness, and also the workpiece material.

3.CNC Grinding

Grinding involves using grindstones, grinding wheel, hand-cranked knife-sharpening, or grinders for performing an abrasive machining process. Abrasive particles cut metal wherein a bond material is mixed with temporary binders, and the metal is shaped pressing the grinding wheels. This machining process is a mechanical type of machining incorporated into CNC machining.

4. CNC Boring

Boring is the process of enlarging existing cast or drilled holes. The types of boring include line boring (one of both ends supported by a boring bar), back boring (boring a hole on the workpiece’s back part), and lathe boring (enlarging a hole with a single-point cutting tool to create tapered or square holes).


5. Laser engraving

High-precision labeling or marking is performed best by laser engraving, utilizing laser technology for permanent marking, flexibility, fast cycle times, and production line integration. It’s a cost-efficient labeling process for metal parts.

Precision metal stamping can be done with laser technology through laser engraving. With metal precision stamping, labeling metal products with appropriate serial numbers, identity codes, or brand names and model numbers can be achieved with precision and uniformity. Impress your clients and investors by adopting laser technology.


Now you’re more knowledgeable about the different types of cnc metal machining and processes involved. Depending on the workpiece or material used, as well as your desired product outcome, machining involves the use of different tools and techniques. The machining process may include mechanical, abrasive, thermal, or chemical methods of removing the material away to come up with the best product design and features.

Whether you’re a novice entrepreneur or someone who is looking forward to cnc manufacturing and supplying metal parts for automotive, electronics, and other industries, understanding metal machining will help you with planning. While there are so many things to learn, consulting a metal machining expert can definitely help you achieve your goals.
