LC 60 - 130

Small gears with a big effect.

The powerful LC 60 - 130 gear hobbing machines feature a very compact design. They were specially designed for the diverse requirements of the automotive industry.

Module 2.75 mm
Workpiece diameter 60 - 130 mm

  • Minimized set-up time

  • Easier operation

  • Smaller footprint

Machine concept

The high-speed machine opens up extensive potential in terms of efficient gear production.

The compact concept requires 20% less floor space. The well-known and proven advantages of the attached accumulator and the integrated loader are still available.

Significantly increased axis and spindle speeds improve productivity and allow more complex machining processes such as roughing, finishing and chamfering with distinct tools in one setup.

Customer benefits Efficient gear hobbing

The development of this machine was focused particularly on high availability.

Maintenance and service costs have been specifically minimized. Among other things, the introduction of a central lubrication system has reduced maintenance requirements by approx. 75%.

The clearly structured arrangement of electric, hydraulic and pneumatic equipment in maintenance units was just as important in the development of this machine as good accessibility for essential maintenance and servicing work.
