V Grooving Machine To meet the small radius requirement of elevator and high-end decoration industries, CNC V聽Grooving machine is mainly developed to make a V-shaped cut or channel along the surface of different metal sheets including stainless steel, ordinary steel, aluminum, copper. This cut along the fold line acts as a hinge, facilitating the bending of metal sheets to have a relatively small bending radius. The depth, width and angle of the cut or channel depends on how deep the blade of V Grooving machine get into the sheet and the shape of the blade. 聽 Blue Blue White鈥檚 horizon
