The Machining of the gearbox To make a worm gearbox, first take a blank of an alloy. A bronze bearing is made in the center of the blank. The hobbing cutter is then used to reduce the diameter of the blank relative to the finished height of the tooth tip on the gear wheel, so the depth of the cut needs to be added to the blank’s diameter. The necessary threading tool is grind to cut the worm. The side clearance on the left-hand side of the cutter tip is allowed for the worm’s pitch angle. The best finish is put on the cutting tool using a slip stone. Gear blank is then mounted on a turntable that acts as a bearing support. This bearing support is mounted on the rear of the lathe cross-slide with the hobbing cutter mounted between the centers. The two worms are then machined, out of which one is made the cutter and finally the cutter is used to machine the worm gear. China difference between worm and worm wheel high China worm gear advantages precise CNC equipment, such as Slow-feeding wire-cut machine, jig grinding machine and electric discharge machine, ensures the top quality precision of mould processing, with the high efficient and environmental protection acid rolling line being the largest raw material converting equipment in the field in china; The wildly use of automatic milling machine, high-speed automatic feeding punch, high speed automatic rolling and assembling machine guarantees the high quality and efficiency of components and chain making.
