How does CNC Milling work?
CNC stands for Computer Numerical Control as is a popular rapid prototyping service. To create a CNC component, first we will need a 3D file of the solid body you wish to create. If you don’t have a 3D file we can help you produce one.
Once we have the file we use CAM (Computer Aided Manufacturing) software to create a tool path. within this tool path we will programme in the tools we wish to use and we’ll enter important information such as spindle rpm and feed rates. these vary greatly depending on the tool used, material and depth of cut. Once we have a tool path we post process it, this turns the tool path into G-code which is a language the CNC machine understands. This G-code tells the machine the exact coordinates and steps in which it needs to move to complete the operation.
We programme the machine, set up the tools and ensure the stock is secured safely. The machine then takes over and completes each step of the operation whilst automatically changing tools. The rotating cylindrical cutting heads remove the solid material in the form of chips leaving on the material required by the component.
High precision, rapid material removal and repeatability make CNC machining a trusted method of manufacturing. Not the right service for you? Perhaps our Laser Etching is though?
CNC Milling Key Features
CNC milling completes operations with incredible accuracy, capable of maintaining micron tolerances
EASY TO REPEAT
CNC ensures perfect repeatability, great for batch production runs.
Design software allows manufacture to be digitally simulated, ensuring all features will be cut first time and reducing the chances of tool breakages – saving both time and money

Vertical Milling Centre
We offer 4-axis machining at our workshop in Henley-on-Thames. We specialise in producing one of products and small batch production runs. Our well-equipped VMC (Vertical Milling Centre) is used daily to produce a wide array of components.
All machined components undergo thorough Quality Assessment to ensure they meet the design specifications.
We work with wide variety of alloy metals, we frequently have custom tooling made for projects. If you have specific questions regarding a component please feel free to contact us to discuss your project in detail.
PRECISE CNC MILLING
Precise cutting is essential to ensuring a component comes out of the machine the exact size it should. To ensure this happens on repeatable basis we always use regularly calibrated measuring equipment to set our machine and inspect components.
Prior to running any cutting programmes we inspect our cutting tools to ensure they are fit for purpose, if they fail inspection they are sent off to be reground or replaced with new.
Time is taken to ensure that all work-piece and tool offsets are recorded and programmed correctly to ensure reliable and repeatable performance.
INDUSTRIES USING CNC MILLING
CNC machining is a popular and trusted manufacturing technique. It’s versatility and ability to cut virtually any solid material make is a popular choice of manufacturing.
Because of its accuracy and versatility, you will find CNC components throughout all modern industries worldwide.
CNC has been pioneered by several specific industries and is still favoured for the vast majority of component manufacture. Below is a list of industries which frequently use the manufacturing technique:
COST EFFECTIVE CNC PROCESSING
As CNC Milling can be an expensive way to manufacture components, we constantly look at how we can make this service affordable and accessible. This type of manufacturing can often seem out of reach to small businesses and individuals who are looking to innovate products of the future. We aim to bridge the gap by offering a professional CNC service at affordable rates.
Some agencies prefer to work to bulk orders, however we understand that sometimes individuals require the same level of professional service to create one-offs and prototypes. We don’t therefore have minimum orders for this service.
If you have any questions regarding this service our team are happy to offer advice so please contact us.
