Built on a shared modular platform, the KX 160 Twin is designed to optimize continuous generating grinding of planetary and final drive gears for automobiles with front wheel drive or automatic transmissions. This machine includes two identical workpiece spindles arranged at opposite sides of an indexing table. While machining one part, the second workpiece spindle simultaneously unloads/loads and aligns another part, increasing output.
The machine can accommodate external spur and helical gears of modules ranging to 4.5 mm (5.6 NDP) with an OD ranging to 270 mm (10.6"). It includes an integrated profile dressing unit for conventional dressable grinding worms. Diamond profile roll sets are used for dressing tools. Grinding worms can be dressed for machining of the dressing-tool root, as well.
A Siemens Sinumerik 840 D controls a total of 10 NC axes. These include two directly driven workpiece spindles, the tool spindle, the swivel angle and rotary motions necessary for grinding.
