What is CNC machining / working principle

CNC numerical control is a metal subtractive manufacturing technology.The cutting shape and size of the tool is controlled by a computer program, and the abbreviation CNC stands for Computer Numerical Control.

The advanced CNC machine can produce the products you need on time. Hemtom Model adopts fully automatic CNC machine tool, which determines everything from the movement of the cutting head and parts to the spindle speed and RPM through intelligent programming, and directly controls the CNC machine tool without manual operation.

Engineers define the shape and mechanical properties of the part in CAD software, and then translate this information into manufacturing instructions for CAM (computer-aided manufacturing) software. Finally, it is converted into a recognizable “G-Code” format and loaded onto the CNC machine to start cutting.

At the beginning of machining, the tool is in contact with the workpiece, and the tool and workpiece are moved and rapidly rotated according to the CNC command, making accurate cuts until the part is completed.

Frequently Asked Questions

CNC machining is suitable for the variability characteristics of new product development and small batch manufacturing requirements. If you don’t want to invest too much, want to reduce complicated projects and speed up the transaction time, you can choose our CNC processing.

Materials used for precision CNC machining generally have properties such as dimensional stability, ease of processing, corrosion resistance, and impact resistance. CNC machining can process metals, alloys, composite materials, semiconductors and engineering plastics. For example: stainless steel, steel, brass, aluminum and aluminum alloys, titanium, copper and copper alloys, polycarbonate, etc.

The basic guarantee of CNC processing technology is traditional processing, which is to improve CNC processing on the basis of traditional processing. In addition to the difference in operation and formation, CNC machining has higher precision and wider flexibility, which reduces work efficiency. Although it has certain advanced technology, it still has its own shortcomings. Both CNC machining and traditional machining are guidance documents that guide operators to gradually produce parts into qualified parts.

We have 50+ machines for your 24/7 rapid prototyping service, and 300+ technical staff to realize the freedom of mass production for you.
Our CNC processing depends on the number of pieces and materials that customers need to make. The cost of a single piece or two or three pieces will be higher, because we need to count the cost of mold opening. After the mass production is realized in the later stage, the additional money will be less.
Our CNC machining parts are guaranteed to be within 0.01-0.05 mm. After the product is completed, it will be processed and inspected to ensure that the product is of high quality and high precision.
