Single-table gear grinding machines for high-volume production quality
With a one-table design and a new-design grinding head, the Liebherr LGG 180 and LGG 280 machines greatly reduce grinding times for twist-free profile and generating grinding.
Ideal for consistent high large-scale production quality in automotive applications, including conical gearing, these space-saving machines can be arranged to provide a complete production line for grinding all gearing components for an automotive transmission: planetary and sun gears, bore-type gears, as well as drive and pinion shafts with lengths up to 500 mm.
The advantage to the one-table solution: higher quality throughout the entire production. There is one clamping fixture, one geometry, so each part is machined under the same conditions for the highest reproducibility. The one-table approach provides the statistical capability and reliability in continuously producing controlled µ-range finish quality for gear noise optimization.
Liebherr Bin Picking Automation
Removing randomly placed items from a container as a human can requires the complex interaction of image recognition system software, robots, and a sophisticated handling strategy. It’s the ultimate industrial automation challenge.
This intelligent removal of items, such as the automated picking of unsorted components, is referred to as random bin-picking. After picking up the part from a container, they must then be perfectly positioned onto fixtures, production lines, or assembly lines. The potential for productivity and efficiency improvements is huge.
At IMTS, Liebherr will demonstrate custom bin-picking solutions for components weighing between 1 and 50 kilograms.
New hobbing machine with separate Chamfer Cut operation
The new LIEBHERR LC 180 Chamfer Cut in one set up hobs and generates the precise and reproducible chamfers required by the automotive user without adding to part cycle times.
The new machine integrates a complete second machining unit for Chamfer Cut tools – in effect, two machines in one – avoiding any increase in machining cycle time. Time savings comes from two simultaneous operations in the machine at once in two separate machining positions: gear hobbing on a stable, maximum-rigidity device, and chamfering on a simpler, collision-optimized fixture.
The solution can chamfer both face edges of the workpiece without the usual change of rotation direction, creating an additional time advantage. Also, the length of the hobbing tool can be maximized, enabling total tool costs to be further reduced. Simple setup through the Liebherr touch screen CNC.
The Liebherr Group has been designing and manufacturing gear-cutting machines for nearly 60 years. Since 1962, these activities have been centred at Liebherr-Verzahntechnik GmbH in Kempten, Germany. Today, Liebherr is one of the leading manufacturers of CNC gear-cutting machines and automation systems.
The company manufactures gear hobbing machines, gear-shaping machines, generating and profile grinding machines and gear-cutting tools. In the field of automation systems, in cooperation with well-known machine manufacturers, Liebherr supplies machining lines, automated machining centers, and system integration of machine tools with gantries, robot integration and pallet-handling systems.
Liebherr-Verzahntechnik employs about 1,300 people worldwide and has manufacturing facilities in Kempten (Germany), Ettlingen (Germany), Collegno (Italy), Saline (Michigan, USA) and Bangalore (India) with service globally.
