What is CNC Machining？
What is CNC Machining Used for?
- Precision CNC machining
- Fast Machining for low volume manufacturing
- All kinds of production and rapid prototyping
- Rapid machined parts requiring high-quality surface finishing
- Metal and plastic prototypes requiring high tolerance specifications
Advantages Of CNC Machining
- Fast production. The processing speed is fast and the efficiency is high.
- It is widely applicable to a variety of materials.
- The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high.
- Easy customization, suitable for new product development and modification. If you want to change the shape and size of the part, you only need to modify the part processing program.
- Very suitable for multi-variety, small batch production. The production efficiency is higher and the investment time is less. Compared with developing molds and injection molding production, it is more economical and cost-effective.
- It can process complex profiles that are difficult to process by conventional methods.

CNC grinding utilizes abrasive grinding wheels to achieve extremely tight tolerances and high surface finishes. Our CNC grinding services offer both cylindrical and surface grinding.
Laser Cutting and Engraving
Laser cutting and engraving employ a high-powered laser beam to cut or engrave various materials, ideal for intricate shapes, signage, and custom metal or plastic components.
Sheet Metal Fabrication
Our sheet metal fabrication services often provide a range of processes, including laser cutting, bending, welding, and finishing services, used for creating enclosures, brackets, and panels.
CNC Prototyping Services
Prototyping services use CNC machining techniques to create rapid prototypes, valuable for product development and testing, enabling designers to assess form, fit, and function.
CNC Machining Tolerances
Our general tolerance for CNC machining of metals is DIN-2768-1-fine, and for plastics, it is DIN-2768-1-medium. Tolerances up to .0008” (0.020mm) are available upon request. Tolerances are greatly affected by part geometry and material type, so we strongly recommend consulting our engineers before starting any project. We are working with you at every step to ensure that your parts meet and exceed your expectations.
