High precision and accuracy

CNC numerical control machining uses advanced computer programming and control technology to accurately control the movement trajectory and processing parameters of the tool, thereby achieving micron-level or higher-level processing. The typical accuracy of today’s CNC machine tools has reached two thousandths to four thousandths of an inch or 0.05 to 0.10 millimeters, and the repeatability accuracy is close to or better than eight thousandths of an inch or 0.02 millimeters. This means that once a program is verified, two, ten or a thousand identical parts can be easily produced with the same accuracy and consistency, achieving mass production and meeting the industry’s stringent requirements for precision parts.

High efficiency

Compared with traditional manual processing methods, CNC processing can realize automated continuous processing, which not only greatly reduces manual operation errors, but also can quickly complete the processing of complex parts, greatly improving production efficiency. At the same time, because the CNC machining center can complete multiple processing tasks at the same time, it can also reduce the clamping and replacement time of workpieces, further improving production efficiency. In addition, CNC machining can also achieve multi-axis linkage and efficiently process complex curved surfaces and shapes, thus improving production efficiency and processing quality, helping companies quickly respond to market demand to enhance competitiveness.

High adaptability

CNC processing can be adapted to various materials, whether they are high hardness materials or brittle materials, including metal, plastic, wood, etc., it can be easily processed. Not only that, CNC can also adapt to the processing of various complex parts. Whether it is a simple straight line, an arc, or a complex curved surface or spatial structure, it can be processed accurately through programming, making product design more free and flexible.


CNC machining can control the machine tool through computer programming, so that different machining operations can be achieved. This makes CNC machining very flexible and adaptable to different market needs and different workpiece types. At the same time, since CNC machining is digitally controlled machining, computer simulation technology can be used to simulate the machining process and verify the correctness of the program, thus ensuring machining quality and accuracy.

 Strict quality control

The precise control and repeatability of CNC machining make product quality more stable and reliable. And because each part is processed according to the same standards, the quality differences caused by human factors are greatly reduced, which not only improves the product qualification rate and consistency, but also reduces the scrap rate and rework rate.

Promote intelligent development

Through the integration with other advanced technologies such as the Internet of Things and artificial intelligence, CNC processing realizes real-time monitoring, data analysis and optimization adjustment of the processing process, further improving the efficiency and quality of operations and moving the manufacturing industry to a higher level.

Environmentally friendly

The mechanization of CNC processing reduces the waste rate of materials, not only improves material utilization, but also reduces energy consumption, which meets the requirements of sustainable development in today’s society.

Cost savings

Although the initial equipment investment for CNC processing is relatively high, however, as these machines become more widely available and used, supplies will increase, and costs will go down. And its efficient processing capabilities and stable product quality can greatly reduce costs during the production process. Labor costs, material losses and subsequent processing costs improve the economic benefits of the enterprise.

What does CNC machining do?

CNC machining is a manufacturing process that uses computer numerical control systems to control the movement and operation of machine tools. It is capable of performing various tasks such as precise cutting, shaping, drilling, milling, and turning of a wide range of materials. It can produce complex and highly accurate parts and components with tight tolerances. CNC machining is widely used in industries like aerospace, automotive, electronics, medical, and many others to create high-quality products with consistent quality and performance. It allows for efficient mass production as well as the customization of individual parts, meeting the diverse needs of different applications.

What is CNC vertical milling?

CNC vertical milling is a machining process in which a rotating cutting tool is used to remove material from a workpiece. In a CNC vertical milling machine, the workpiece is held firmly in place on the worktable, while the cutting tool spins and moves vertically along the z-axis and horizontally along the x and y axes, controlled by a computer numerical control system. This enables precise and accurate shaping, drilling, slotting, and other operations to be performed on the workpiece. It is widely used for manufacturing various components, prototypes, and complex geometries in industries such as aerospace, automotive, and mechanical engineering. The ability to program complex tool paths and achieve high precision makes CNC vertical milling a crucial process for producing high-quality and intricate parts.

Briefly introduce the basic process of CNC machining.

The basic process of CNC machining typically involves several steps. First, the design of the part to be machined is created using CAD software. Then, the CAD file is converted into a CNC program that instructs the machine on the specific tool paths and operations. The workpiece is then securely fastened on the machine’s worktable. The CNC machine, guided by the program, starts the machining process, with the cutting tool precisely removing material according to the pre-defined paths. This may include milling, drilling, turning, or other operations. Throughout the process, coolant is often used to cool the tool and workpiece and remove chips. Finally, the machined part is inspected for quality and accuracy to ensure it meets the required specifications.
