CNC machining is a subtractive manufacturing process that removing materials with a variety of precision cutting tools to make a part or product. Advanced software and optimized programs are used to control the equipment according to the specification of your 3D product design. Our team of engineers and machinists program to control the equipment to optimize cutting time, surface finish, and final tolerance to meet your design specifications. We use CNC machining not only to manufacture parts and prototypes but also to make mold tools, which can be used for our Plastic injection molding or pressure die casting services to serve for your next projects and cases.

CNC Milling
One of the most common examples of CNC machining is CNC Milling. CNC Milling devices are multifaceted, meaning they are able to achieve many operations undertaken by cutting and drilling machines, yet with some notable differences. For example, the cutter in a CNC Milling machine is able to move along multiple axis, meaning it can create a variety of shapes, slots and holes.

CNC Turning
CNC turning is another important CNC machining way which enable high speed and quality turning of both plastics and metals. The turning process allows for complex external geometries and internal bores to be generated. Our turning capacity is available for prototypes through to low-volume production.
