The machine can perform simultaneous, double-sided machin- ing on 12 or 24 stations with as many as 150 switching cycles/min. The system can produce as many as 600 parts/min. According to the company, the machine uses various loading systems including a vibrator y, linear or inclined conveyor, and a pick-and-place system for loading parts directly from the feed or pallet.

The standard LGG 180/280 machine has been upgraded to an LGG 180/280 L "large version" to cater to special customer needs. An additional new machine for large workpieces, the LGG 300/500, has also been added to the lineup. Liebherr is also introducing new grinding heads for all LGG machines. The LGG 180/280 L combines typical mass- market requirements with those of job shops. As a single-table solution with only one clamping fixture, it can machine planet and sun gears, ring gears and beveloids ver y cost-ef fectively, the company says, achieving short load/unload times of less than 4 sec. This machine can also grind drive and output shafts ranging to 660 mm or longer. Given its increased working space, it is suitable for machining smaller batches typical in job shops and aerospace suppliers. The bigger LGG 300/500 model provides a relatively compact footprint for parts ranging to 500 mm in diameter. Like the smaller LGG 180/280, the LGG 300/500 has been approved for the use of grinding tools with cutting speeds ranging to 100 m/sec. The new LGG machines are suited to generat- ing grinding of tooth-flank modifications: twist-free (TF), deviation-free topological (DFT), noise exci- tation optimized modification (NEO), generated end relief (GER), silent shift grinding (SSG) and dresser-independent profile modifications (DIP).
