The KX 160 TWIN and the KX 260 TWIN generating gear grinding machines are each designed on a shared modular platform with features specifically for continuous generating grinding with dressable tools. Very short set-up times are highlighted on this efficient machine.
The KX TWIN type generating gear grinding machines are particularly designed for medium and large batch production of gears and shafts where quality levels are especially demanding.
The machine includes two identical workpiece spindles, arranged at opposing sides of an index table. While machining one part, the second workpiece spindle simultaneously unloads / loads and aligns another part. Thus, many of the auxiliary functions are carried out during the machining time, cutting the auxiliary processing time to a minimum.
A total of ten NC-axes align the gear wheel with the tool and perform the necessary linear and rotary motions during grinding. Both the index table and tailstock are designed as NC-axes. The workpiece spindle and tool spindle of these generating gear grinding machines are direct drives.
The design of these machines includes an integrated single spindle dresser for conventional grinding worms. Mounted staggered to the workpiece spindles, the dressing unit is assembled on the tailstock column, too. For the dressing process the profile dressing unit is aligned with the tool by turning the tailstock column.
