Bar Peeling is the machining process by which a raw forged blank is converted into a polished bar.

During this peeling process, surface cracks and oxide layers are removed giving a perfect roundness with
good surface and dimensional accuracy to the bar.	1	2	3	4	5	6	7		8
The range of materials that can be machined with these tools is vast and goes from all kind of Steels to Cast
Iron parts.
