HF 1250
Designed for workpiece diameters of up to 1,250 mm, the HF 1250 cylindrical gear hobbing machine combines leading technology with the perfect design: a machine table with torque motor drive, a heavy-duty gray cast iron machine bed, and integrated workpiece inspection are just some of its features. Through the use of HSS or indexable insert cutters and high-performance gashers in wet or dry cutting processes, this versatile cutting machine sets new standards in productivity and quality ideal for suppliers of durable, heavy-duty industrial gearboxes.
