Yumoto Vietnam has two types of high-quality Okuma CNC lathe processing machines. A CNC (computer numerical control) machine operates according to pre-programmed instructions and can process parts much more efficiently and accurately than manual machines. For CNC lathe machine, the workpiece rotates against a stationary cutting tool which removes pieces of material until the workpiece becomes the desired shape. Because the machine operates by rotating the workpiece, it is best used for processing precision parts made from materials of cylindrical rods. The lathe machine can process all kinds of plastic and metal materials, including harder ones such as steel.
