LC 180    80 DC with integrated /2 ChamferCut unit Fast. Economic. Precise. The ChamferCut process With the LC 180 / 280 DC, the ChamferCut unit is integrated on the operator side. This unit was developed towards user-friendliness. As such, the machine operator has unobstructed accessibility to both machining positions. Chip removal has also been significantly improved. Using the proven Liebherr ringloader concept, the workpiece can be transferred quickly and efficiently between the gear hobbing and chamfering machining positions.The ChamferCut process takes place parallel to gear hobbing....

Machine table For gear manufacturing, a workpiece drive with absolutely zero backlash is required. A table drive featuring preloaded zero-backlash spur gears and high torque is available for the application of universal technology. For high performance cutting (HPC), a highly-dynamic direct drive is available that fulfills all speed and precision requirements. Hob head Besides the default gear driven hob head, a directly driven hob head is available as an option. The directly driven hob head is distinguished by its high speeds of up to 6,000 rpm and its high drive power of 23 kW. It offers...

Alliance Member Partner of the Engineering Industry Sustainability Initiative Optimum machine accessibility during maintenance work is important for ensuring productivity. For this purpose, all necessary maintenance access points are equipped with doors. Moreover, for the additional monitoring of specific signals quickly and easily, window panes are inserted into the maintenance doors. As a result, the machine operator or servicing personnel can read the signals from outside in very little time. Additionally, an enclosure for the hydraulics has been integrated into the new machine...
