What is Precision CNC Machining?

Precision CNC machining means the processing, which instructions were sent by the control system of computer, and which will make the machining tool perform various motions as requested. In this processing, the digital and letter represent the requirements of the shape and dimension of work piece, as well as the requirements of processing technology.


The advantage of Precise CNC machining

The CNC machining is much faster compared with the traditional manual machining. As long as the the computer code is correct and complied with right design, the accuracy of finished products will be very high, and the deviation will be very small.

CNC manufacturing is an ideal manufacturing method for rapid prototyping. CNC machining can also be used to manufacture end-use products and components. 

At Kesu Hardware, we provide high precision CNC machining Services for complex and difficult parts in Aluminium 7075, Titanium, Magenisium, Inconel 718, Stainless Steel 17-4PH, Ceramics, ABS, PEEK etc. One-stop manufacturing service for large parts, intricate parts and high precision parts in both low-volume and high-volume.

We're ready to take on jobs of any size, from a single part to one million parts, for CNC milling and CNC turning.
