Gear hobbing machine LC 700

The Machine Concept

For the development of this machine series the characteristics of the very successful new machine generation from Liebherr was systematically transferred to the application of the universal machines LC 600 – LC 2000. The necessary flexibility for different applications is achieved with a two-piece machine bed. With this concept the machines can be optimally configured to customer specific requirements. The self-supporting, very rigid design permits a machine installation directly on the floor, without a special foundation. Chip removal is accomplished through the machine bed with the main chip conveyor arranged lengthwise. The machine bed and lateral
