Flexibility is essential for job shops and small lot sizes. The new LGG series has been specially designed for universal use, as well as for large series production. It combines three technologies: Generating grinding, profile grinding and internal grinding. This technological diversity provides the universal user with maximum benefit and a secure investment for the future. This machine can be configured for individual applications, so it is perfect for use in the production of large batches. This is where external automation systems such as a plastic chain conveyor or a robot system are used. Liebherr also offers a manual generating and profile grinding machine for small batch sizes and outstanding flexibility. Generating grinding max. workpiece diameter (mm): 500 Profile grinding max. workpiece diameter (mm): 700 The machine is exclusively loaded manually. A handling device (crane) mounted on the machine roof and an NC-swiveling tailstock make manual loading much more simple. Process-optimized external grinding heads and internal grinding arms are available for the LGG. Balancing systems inside the spindle are used in both external grinding heads (GH 320 and GH 240 CB). On the GH 320 CB, the balancing system is integrated in the arbor. High drive power and speeds are major advantages – for example, when using new grinding materials. The modern tool holding makes it possible to replace the grinding arbor quickly and easily. Small grinding tool diameters are available for collision-critical workpieces and for special tooth corrections. With the GH 320 CB grinding head, it is now also possible to efficiently grind optimal-quality workpieces up to module 14 mm.
