Liebherr Gear Technology will be displaying a variety of technologies at Booth #236914 (North Hall) during IMTS 2022. 

LGG 180/280 generating and profile grinding machine

The Liebherr LGG 180/280 stands out with its compact design, impressive accessibility and ease of setup. Different grinding heads can be used on the machine for every specific application. Also, an internal grinding arm can be adapted very quickly and easily – and even retrofitted. This means that both external and internal gears can be machined very economically and efficiently on this machine.

The GH240CB grinding head can accommodate large grinding worms with a width of up to 200 mm, considerably increasing productivity and economic efficiency. In addition, large multiple sector grinding worms can be used, which are ideal for generating grinding, finishing grinding and polishing grinding. Collision-critical gears can be ground with very small grinding worms, thanks to the extremely rigid spindle bearing and the counter bearing. The integrated centrifugal unit removes chips and coolant from the ground workpiece, eliminating any undesired oil loss in the machine.

Digitalization solutions: Customized digitalization solutions for your requirements 

With a combination of data profiles, protocols and the LHWebPlatform, Liebherr provides an infrastructure for the acquisition, transmission, storage, processing, provision and display of machine, operating and production data. In the basic app LHMachineInfo, users can see the live status of their machine tools at a glance and observe changes in real time. The LHSignalInfo app visualizes the recorded signals, taking into account all measuring points and their exact time stamp. Liebherr has expanded the range of functions of LHWebPlatform to include a further tool: The LHReportInfo app visualizes and analyzes the performance of the machine and generates reports and evaluations from the machine data – a decisive step toward more productivity.

WGT 280 and WGT 400 gear inspection devices

The four-axis measuring instruments of the WGT series have high-precision mechanics and electronics, which are controlled by smart and user-friendly software. They meet all accuracy requirements regarding gear measurement and comply with VDI guideline VDI/VDE 2613, group 1. In addition to the gear inspection machine options available as standard, customer-specific solutions are also available, such as adjusting the travel range on the Z-axis, longer tailstocks to accommodate long shafts, and rotary tables adapted to the payload. An automatic sensor changing system ensures uninterrupted measurement of the workpieces and also offers the highest levels of convenience for the user. The extensive software features make the machines suitable for measuring all types of gears, such as spur gears, bevel gears, worms, worm gears, shafts, gear cutting tools, and other rotation-ally symmetrical parts.

Pallet handling systems as a productivity booster 

Liebherr pallet handling systems open the door to increased productivity, even for small batches. 

Pallet handling systems handle workpieces on uniform transport pallets. This makes them the ideal automation system for one-off and small batch manufacturing, facilitating unmanned shifts through to “lights-out manufacturing” and enabling unit costs to be reduced by up to 40 percent and machine running times increased to up to 90 percent. The application and combination possibilities are diverse 

The rotary loading system provides compact automation for one or two machining centers. The modular PHS Allround can be expanded in one-meter increments and links up to four machines. This means that the front ends of the system can also be used, and attractive options such as front access for machine access without downtimes, or the double loader for even more productivity, are available. The PHS Pro has no upper limit and can automate any number of machines, also with integrated material management.

Bin picking solutions with LHRobotics.Vision: From the technology package to the turnkey robot cell 

Liebherr supplies automation systems for automated raw parts input and finished parts removal in production facilities and possesses extensive system and software competence for position and object recognition with 2D and 3D camera systems. 

With the LHRobotics.Vision technology package, Liebherr is making this industrial application expertise available to a broad range of users of robot integrations, to withdraw unsorted components from deep bins with process reliability. As a manufacturer of bin picking robot cells, Liebherr knows the challenges of the application and, with the aid of artificial intelligence has simplified the software so much that it can be intuitively used by anyone. 

The technology packages consist of a 3D image recognition system and the LHRobotics.Vision software for object identification and selection, collision-free withdrawal of parts, and robot path planning up to the depositing point.

A special feature is the optional simulation tool LHRobotics.Vision Sim. This enables the user to test and optimize the processes in a completely virtual manner, without expensive hardware investment.
