SPKX45 / 2 double-sided groove milling machine is based on the milling machine, absorbing advanced technology and processing technology, highlighting the double-sided groove milling, so that it can adapt to user requirements double-sided milling, the workpiece only once positioning it Can be completed on the double-sided groove milling, both to ensure the processing accuracy, but also improve the production efficiency. The equipment is mainly composed of bed components, electric control system, hydraulic system, pressure beam mechanism, lubrication system, left and right lateral sliding table, hydraulic presser foot, column assembly, reduction box, spindle parts and worktable components. The use of strengthening the spindle milling head and a specially-shaped cutter head, so that it can adapt to the special groove milling, reduce the footprint, in order to facilitate the placement of other components. The whole milling spindle adopts vertical arrangement. The worktable adopts the way of moving. The bed rail adopts roller linear guide, and the feeding adopts the screw rod transmission, which makes the equipment more accurate in milling and smooth transmission.
