ROLL GRINDER

The machine is designed to grind barrels and cut flutes on rolls of roll machines.The shaping mechanism permits to obtain convex (barrel) working surface.For the wheelhead precise cross travel there are used roller guides and a ball-screw couple.Three independent cutting tool heads permit to cut larger flutes at 1,25 of the roll rotation and smaller ones at 0,5 of theroll rotation, thus considerably increasing productivity of the machine.Hydraulic withdrawal of the tool heads increases stiffness of the toolholder.Automatic cross feed of the wheelhead and its automatic stop after preset allowance removal permit an operator to operateseveral machines simultaneously.The wheelhead dynamic electronic indicator balancing ensures high quality of the ground surface.
