Machining centers are machines that can process precision parts and change tools according to the pre-programmed instructions. In CNC milling processing, the workpiece is placed on a fixed position while a cutting tool moves to process the workpiece in the desired shape and size. At Yumoto Vietnam, we have 3-axis, 4-axis, and 5-axis milling machines. We use the 3-axis milling machines for simple precision parts, and the 4-axis and the 5-axis for more complex shapes and processing procedure.
