Features:
This series of machine tools is suitable for large and single production of cylindrical spur, helical gears, worm gears and sprocket.This series of rolling cut machine common worm is the method of radial feed processing.The machine is fitted with a power single indexing device by which gears of relatively large module can be pre-slotted with disk milling cutter, with the reverse finger cutter body can be processed without air knife slot miter gear.The machine is characterized by good rigidity, high working accuracy, easy in operation and maintainance.Main technical data:
