Precision CNC Machining Services

CNC machining means a lot to the modern manufacturing industry, the high efficiency greatly facilitates the precision machined components manufacturing, which results in high demands of CNC machining services and CNC machining parts widely used in a host of industries and areas.

What is CNC Machining Service? CNC (Computer Numerical Control) machining services applying the CNC process, which is a subtractive fabrication method use computers to control the machines and tools complete major production operations of custom precision CNC machined parts or tooling, through removing extra materials from the workpiece based on programming languages. The final CNC product has exact specifications. 

Benefits of CNC Machining Services

- Improved efficiency and decreased labor cost with high level automation
- High accuracy and precision are guaranteed with minimizing the potential human error
- A broad selection of materials, like metals, plastics, rubber, foams, woods, etc.
- CNC machines can repeat the completely same operations according to the designs and produce identical parts
- High throughput potential in short-run manufacturing

Rapid CNC Machining Services Online - Custom CNC Machined Parts Manufacturer

Dajin Precision ( is an accomplished one-stop CNC machining services China supplier and cheap precision CNC machining parts manufacturer, engaged in custom CNC turning, CNC turning-milling, and CNC drilling service. Multiple surface treatment are provided as well. Our capabilities are sourcing a broad range of turning parts from simple shafts, screws, nuts to complex CNC machined components cost-effectively based on sophisticated equipment and professional engineering team.

CNC Turning Services: common machining process for CNC turning parts production, use the cutting tool to remove extra parts of material block while the workpiece held in a chuck on rotating spindle on turning machines, we provide custom turning, hard turning service and the full range of turned machine parts with maximum turning diameter Ø20, turning length 150mm and a very tight range of tolerance.

CNC Drilling Services: CNC drilling starts with uploading the CAD file of required parts and installing drill bit on the drilling machine, after the material secured on the machine, operate the spindle and drilling needed hole sizes and diameters, which controlled by computers. Our skilled workers will work closely with clients to deliver precision drilling machine parts.
