What is CNC machining?
CNC Machining is composed of: CNC ( Computer Numerical Control) + Machining.
- ”CNC“ means entering a pre-program into a machine through a computer, to control the movement of tools and machinery.
- ”Machining“ are the processes to use suitable machines and cutting tools to remove material from the workpiece, and turn it into the shape you designed.
Talk more:
- NC (short for “Numerical Control”) was an industry standard and was quite popular in the 1950s.
- CNC is the son of NC, with the help of computer programming, it is higher in control accuracy, faster in production speed, and lower requirement of operators, more convenient to change the program, and can run for a long time.
- Although the cost of CNC is higher than NC, people are more willing to use advanced technologies that can improve efficiency and save manpower in the era of great industrialization. Its popularity started in the late 20th century.
- CNC machine: CNC machining center, CNC lathe, CNC router, CNC engraving machine, etc.
- CNC Machining processes include: turning, milling, tapping, honing, drilling, grinding, etc.
- With the popularization of CNC technology, CAD and CAM processes in the design field developed in the following, which made us can produce higher precision and more complex structure parts for industries, and the production efficiency is extremely high.
- Robot programming and the addition of robotic arms, now CNC machining can be fully automatic. This also solves the problem of insufficient productivity caused by the aging of the global population.
- Nowadays, people are always pursuing faster, higher, and stronger, and the machining field is no exception. In the long river of human history, I believe that machining technology and equipment will be constantly updated and iterated. Looking forward to a better future.

CNC Machining Processes
Yontone provides different types of CNC machining services as below: CNC milling, CNC turning, CNC drilling, CNC engraving, CNC grinding, CNC laser cutting, CNC routing, EDM, WEDM, etc.
The workpiece does not move, rotate the cutting tools and move against the workpiece.
After the cutter reaches the specified position, rotate the workpiece, to create cylindrical parts.
Rotate a cutting tool to remove the material, to create a design, pattern, or logo on the workpiece.
Use grinding wheels as cutting tools, and remove a small amount of material, to get better accuracy and finer surface.
The computer program controls the laser beam head moving, cuts through the material, and gets the desired pattern.
Use a fixture jig to position the workpiece, drill holes, and tap in the specified location.

Advantages of CNC Machining Process
CNC machining provides great production flexibility since no mold needs to be created. This is especially beneficial for low-volume product runs.
CNC machining parts have higher dimensional accuracy when compared to those manufactured by casting or die-casting.
The machining process controlled by an advanced software computer ensures the stability of product size and tight tolerance.
Equipment can be easily operated, one person can handle 2-3 machines, this increases production capacity and reduces labor costs per product.
Self-Designed Fixtures
The fixture department of Yontone designs corresponding hydraulic fixtures for different shapes of products. Fixtures designed are convenient for employees to place products, and also ensure machining accuracy and production efficiency.
Custom PCB Cutters
Yontone’s tool department designs integrated PCB cutting tools according to the different product structures and tolerance requirements. The tool designed in this way ensures the concentricity, accuracy, and smoothness of the product meets very high requirements.
Quality Control
Usually, yontone’s QC department inspects the dimensions of products during and after the machining process.
- The operator checks the important dimensions of each machined product during production.
- Inspection personnel of the quality control department. Randomly select the products to do full-size measuring every hour during the machining process.
- Before warehousing, the whole batch of products shall be checked at the ratio of 5% ~ 20% ~ 100%. Specifically according to customer requirements, and also according to the importance of key dimensions.
