Computer numerical control (CNC) machining is a subtractive manufacturing processㅡ, which means it uses machine tools to remove parts of material from a workpiece until it takes the desired shape.
A computer programme (also known as a G-code) controls the sequence in which the CNC machines (or workpieces) move against each other to create the desired part.
Standard CNC machines include multi-axis CNC milling machines, lathes (or lathes) and milling machines. Although all CNC machine types rely on computer instructions to perform subtractive manufacturing, they operate in slightly different modes.
For example, CNC milling machines operate by holding the workpiece in place while the cutting tool rotates relative to the workpiece. In contrast, a CNC lathe makes parts by holding the cutting tool in place as the workpiece rotates relative to it.
CNC machines can create a wide range of features and high precision parts. For example, CNC milling machines are ideal for producing cavities, angles, holes and slots.
In contrast, CNC lathes are suitable for creating parts that are cylindrical or symmetrical near their axis.
Despite this, CNC milling machines and lathes can achieve tolerances of ±0.001 mm.
They are also compatible with a wide range of materials, including metals and plastics, as long as these materials can be used in blocks. This is not the case with additive manufacturing technologies such as 3D printing, which are only compatible with plastics and a few metals.
Titanium and its alloys are increasingly seeing widespread use in aerospace and biomedical applications that take advantage of its unique properties. However, machining titanium also presents unique challenges that precision engineers accustomed to machining other metals will find difficult. Here we look at why machining titanium is so difficult an
Zinc is a relatively common non-magnetic metal. It usually forms alloys with aluminum, magnesium and copper. Zinc has excellent damping ability; it has high ductility and shows long-term dimensional stability. Zinc alloy metal is inexpensive, but has good machinability and is easy to mill.
With the rapid development of industries, the demand for aluminum continues to grow. There are more than 700,000 kinds of aluminum alloy products. Due to its good physical and mechanical properties, aluminum is widely used in construction, transportation, aerospace, electronics, medical equipment, automobiles, machinery, hardware and other fields.
In manufacturing, "complex geometry" refers to parts with a three-dimensional design that has features such as undercuts, hollow spaces or complex internal structures. Complex parts have relatively high requirements on machining accuracy and technology, and are time-consuming, costly, and more challenging.
High-precision CNC machining is still the trend of large or small batch processing. CNC machining involves shaping raw materials into finished products by cutting excess parts specified by computer-aided design (CAD) or computer-aided manufacturing (CAM) blueprints.
Tool steel is any of various carbon and alloy steels, especially suitable for making cutting tools, dies, hand tools, knives, etc. Their suitability comes from their unique hardness, wear and deformation resistance, and their ability to maintain cutting edges at high temperatures.

How does CNC machining work?
CNC machining is a subtractive manufacturing process that uses computerised controls and machine tools to remove some of the stock material until the required bespoke part is made from the workpiece.
The machining process begins with the creation of a CAD (Computer Aided Design) model of the required part, which is then loaded into CAM (Computer Aided Manufacturing) software and converted into a set of computer instructions.
This set of instructions (or G-code) allows the machine to perform different cutting operations at high speeds (thousands of RPM) until the required custom part is produced.
How does CNC machining compare to 3D printing?
Both CNC machining and 3D printing rely on CAD files and computer input to transform the starting material into the required customised part. However, unlike the subtractive CNC machining process, 3D printing is an additive machining process. It revolves around adding material in layers to build the required custom part.
CNC machining offers a wide choice of materials, whereas 3D printing is only available for plastics, polymers and some powdered metals. In addition, CNC machined parts are often stronger than 3D printed parts; therefore, CNC machining is ideal for prototyping and production of functional parts.
What are the different types of CNC machining?
There are many different types of CNC machines, each with its own unique features.
CNC lathes and milling machines have built-in tools for cutting and drilling workpieces through to the manufacture of customised CNC parts. They are available in 3-, 4- and 5-axis configurations, depending on the complexity of the part.
The CNC milling process involves holding the part in place while the cutting tool rotates around it, whereas in CNC turning the part rotates around the fixed cutting tool to form the desired shape.
Unlike CNC milling and turning machines, which rely on cutting tools, CNC electric discharge machining machines (EDM) use electric sparks to machine the material into the desired shape.
If you need to manufacture parts using CNC machining, it is important to know the types of finishes and materials that can be applied to CNC machined parts. Thanks to our surface finishing partners, we can also apply all types of finishing to CNC prototype and production parts. Need a customised CNC part with a high-quality appearance? We are here to help.
Plastics: HDPE, PS, PAGF30, POM, DHPE, ABS, PP, PPS, (acrylic), PCGF30, Teflon, PC, ABS+PC, PEEK, PMMA.
Metals: steel, aluminium, stainless steel (17-4, Inconel 625 and 718), titanium, zinc, magnesium, bronze, brass, copper.
These are rated as common materials for CNC production parts and prototyping.
Numerically controlled machining
As-Machined: the most cost-efficient and popular way of operating components in-house. Uniform and fine toolpaths are also good, for aspect parts.
Sandblasted: parts are left with a matt appearance. a range of 320 to 120 beads allows us to apply different roughnesses to the surface.
Anodising: Type II has a wear-resistant surface. Parts can be anodised in a variety of colours - black, red, clear and blue are the most common. It is usually associated with the low silicon element series of aluminium.
Type III is thicker and produces a wear resistant layer in addition to the corrosion resistance of Type II.
Powder coating: This is a process whereby a powder coating is sprayed onto a part that is then prepared in an oven. This forms a strong, hard-wearing and consumption-safe layer that is more robust than standard painting methods. A wide range of colours can be used to give a perfectly tasteful finish.
We operate all the necessary milling equipment with high precision, so we produce high-quality metal and plastic parts. There is a strict follow-up of machine tolerances and we make adjustments when necessary. Two highly skilled programmers create CAM programs for the numerous machined parts on a daily basis. In addition, a quality engineer follows the first samples off the machine and carries out inspections and adjustments on site.
