Round Bar Peeling Machine

The bar peeling machine is a high-efficiency processing technology, mainly used for the diameter of 10~250 mm in the long metal material peeling processing. It can quickly and efficiently remove the decarburization layer, crack and other defects on the surface of the bar, and achieve higher accuracy and roughness. It is especially advantageous to long material processing, which can improve efficiency several times to more than ten times than ordinary technology. It is widely used in machinery manufacturing, vehicle production, bearing production, spring manufacturing, and other fields.

Product Description

Round Bar Peeling Machine:

Bar Peeling Machine, which is commonly known as a centerless lathe, is a kind of high efficient rotary cutting device. It can be widely used for peeling round bar, steel round bar, stainless steel round bar, and other ferrous and non-ferrous metal bars.


Bar Peeling Machine removes scale, cracks, seams, deformations, decarburized layers, and other imperfections resulting from hot rolling or other processes used for producing a bar or tube. When steel blanks are formed from a forging or hot-rolling process, they generally have surface imperfections like microcracks or discontinuous “skins” that are formed during the cooling process. These imperfections have to be removed before the blank can be formed into a sufficient raw material for further processing. Bar peeling refers to a metalworking process. 


When steel blanks are formed from a forging or hot-rolling process, they generally have surface imperfections like microcracks or discontinuous "skins" that are formed during the cooling process. Metal oxide layers can also build up over time. These imperfections have to be removed before the blank can be formed into a sufficient raw material for further processing. The raw stock can be later machined into finished pieces such as axles, piston rods, or extrusion blanks for manufacturing plastic tubes. In all of these cases, it's important to have a completely smooth, defect-free continuous surface with precise dimensions. That's where the bar peeling process comes into play. It produces the smooth surfaces and critical dimensions for downstream parts processing.


High-speed centerless lathe machines remove scale, cracks, seams, deformations, decarborized layers, and other imperfections resulting from hot rolling or other processes used for producing bar or tube.
