CNC Machining Processes

CNC Milling

CNC milling is to cut solid plastic and metal material into final precision parts using different axis milling processes. Milling can be also known as a perfect way of making tooling for die casting and injection molding. Learn more

CNC Turning

CNC turning is a process of machining parts with cylindrical features from metal or plastic rod stock. This process allows to make any circular parts effectively such as shafts, worms, and spheres, and it can apply to the creation of the parts with complex external and internal geometries and various threads.

CNC Machining Applications

Rapid Mold Making

CNC machining can cut materials with a high variety of fully dense, so it is ideal to fabricate metal tooling for injection molding, fixtures, stamping, blending, high pressure die casting, blow molding, etc.
Our high-speed 5-axis CNC machines make it possible to create mold cavities, lifters, and other mold parts with complex geometry and high precision in just hours which may need days to make by EDM in the past, extremely enhancing our mold-making process.
