Centerless lathe is mainly used to process the outer skin of various metal bars, pipes, wires and other oblong metal materials, which can quickly and efficiently remove decarburized layers and cracks on the surface of bars, and has many advantages such as stable feed, accurate centering of bars, high speed and less tool loss. It has obvious advantages in processing longer bars, with higher efficiency, faster speed and higher precision than usual. Because the round steel peeler can directly peel the long material, the intermediate procedures such as material cutting are omitted, and the output is greatly improved. At the same time, it is also suitable for the production of bright materials and silver bright steel, and can be used in the preparation process of machinery manufacturing, hydraulic cylinder nonferrous metals, titanium alloys, wind power generation, vehicle manufacturing, bearing manufacturing, spring manufacturing, military enterprises, slender shaft production and other mechanical equipment manufacturing, with stable performance and reliable quality. The processing range includes all kinds of models in the whole section from medium 6mm to medium 500mm.
