Inside Gear Expo 2015
Billed as “The Drive Technology Show,” this year’s event featured new machine designs and cutting tools, heat-treat processes, and materials and hardening processes for hybrid transmission applications.
Modular Pallet-Handling System Optimizes Large-Part Manufacturing
Liebherr offers a larger, modular pallet handling system (PHS) designed to provide large-part manufacturers with the same handling flexibility, efficiency and cost savings of its smaller range.
A Map for Market Expansion
How one gear manufacturer freed itself from the single-customer model by adopting new technologies and expanding its customer base to protect against economic uncertainties.
Smaller Shaping Head Increases Stroke Length
Designed for its Platform 2 (LSE/LFS 200 to 500) and Platform 3 (LSE/LSF 600 to 1600) machines, Liebherr Gear Technology will display a smaller shaping head option which eases electronically-controlled machining of spur and helical gear teeth.
Ingersoll Hosts Liebherr Gear Seminar
Presentations from gear manufacturing experts and networking with industry colleagues make this event a valuable experience for everyone involved.
Liebherr Gear Seminar to be Co-Hosted by Ingersoll Cutting Tools
For the past 20 years, Liebherr has offered its annual Gear Seminar along with its business partners, focusing on the latest developments in machining centers, cutting tools and measurement technologies.
Gear Hobbing Machine Reduces Cycle Times
Liebherr’s LC 100 gear hobbing machine is said to be capable of achieving chip-to-chip times of 3 sec.
Large-Scale Grinders Promote Reproducibility
The Liebherr LGG 180 and 280 grinding machines use a one-table design and updated grinding head to quicken twist-free profile and generating grinding.
Robotic Bin-Picking Automation Effectively Channels Random Parts
Liebherr Automation offers a small-workpiece-handling robotic system with 3D software capable of removing randomly placed items from a container and accurately placing them in a machine or production line.
Liebherr Partners with Koepfer
Koepfer America will represent Wenzel GearTech products for Liebherr in selected states.
Producing Precision Gears
They needed precision gears of a variety of sizes and configurations, so what did Liebherr do more than 60 years ago? It designed, engineered and built its own gear-making equipment, which became one of its businesses. And yes, it still produces gears for its own requirements.
Gear Grinding Machine for Production Line Installation
Liebherr’s LGG 180 machine for profile and generating grinding is said to provide short grinding times and consistent high quality for large-scale production.
Measuring Machine Analyzes Small Gears
Available from Liebherr Gear Technology, the Wenzel WGT 280 gear-measuring machine is designed to measure gears smaller than 280 mm in diameter as well as rotationally symmetrical parts.
Hobbing Machine Features Chamfer Cut Unit
Liebherr offers a hobbing machine equipped with a separate chamfer cut unit for deburring and chamfering workpieces ranging to 180 mm.
Hobbing with Chamfer Cut in One Set-up
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 enterprise was established in 1949 by Hans Liebherr. The great success of his first mobile, easy-to-assemble and affordable tower crane was the foundation on which the company flourished.
Today Liebherr is not only one of the world’s leading manufacturers of construction machinery but is also an acknowledged supplier of technically innovative user-oriented products and services in numerous other fields. The company has now grown into a Group with more than 39,000 employees in more than 130 companies across all continents.
Liebherr Gear Technology is a world leader in the development of advanced gear production processes, including hobbing, grinding, and shaping as well as gear tools.
Liebherr Automation engineers a wide range of automated handling equipment from machine loaders to gantry systems and robotics. The automotive industry worldwide is a leading user of Liebherr manufacturing technology.
Random 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.
Liebherr offers custom bin-picking solutions for components weighing between 1 and 50 kilograms.
Gear Production and Automation Solutions by Liebherr
Single Table Gear Grinding Solution
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.
