In 2010 we installed a 200-ton single pass automatic broaching machine. This system allows the internal broaching of ring gears, obtaining DIN class 7/8 quality. As it is a single pass cycle, it means that an investment in one tool can deliver up to module 8.
The 200-ton broaching machine can develop 200 tons of pulling force, has a machining length of 3,600 mm and effective stroke of 3,000 mm.
The break-even for this operation makes it advantageous compared to traditional slotting, starting from volumes of 2500 pieces per year.
