What is Precision CNC Machining

CNC (computer numerical controlled) machining is a manufacturing process of using CNC high precision machines to remove raw materials with various cutting tools, which is automatically controlled by a computer program according to the the desired geometric specifications. Our engineers and machinists will customize computer program to optimize machining time, surface finish and final tolerances to meet specifications of your dedign. We can manufacture different parts from prototypes, small and large volume by CNC machining.


Advantages of CNC Machining

CNC Machining Services Processes


CNC Milling Service

CNC milling is to cut solid plastic and metal material into final precision parts using different axis milling processes. The advantage of multi-axis milling machines realizes versatile, accurate and repeatable CNC milling process for production of different features and complex geometries. Take channels, holes, curves and corners for some examples. Milling can be also called as a perfect way of making tooling for die casting and injection molding. Read more..

CNC Turning Service

CNC turning is a process of machining parts with cylindrical features from metal or plastic rod stock. Compared with CNC milling, the turning process allows us to make any circular parts effectively such as shafts, worms and spheres, and it can apply to creation of the parts with complex external and internal geometries and various threads. Our turning capability can range our service from prototypes to mass production. Read more..
