The new programming system from Liebherr:
25% faster set-up time

With the new LHGearTec software, the system constantly guides users when entering workpiece and tool data, as well as during workpiece correction and process monitoring. The user guidance was redefined in intensive cooperation with designers and users. Attention was also paid to the consistent integration of the control system in factory processes with open interfaces for both measurement processes (closed loop) and MES/MDE/PDA interfaces.

The connection with the new Siemens control generation and the new Liebherr control panel LHStation & LHMobile offer the following highlights:

  • Quick access to the data records last modified
  • Ergonomically optimized operating areas for tool and workpiece input
  • Import and export of workpiece and tool geometries in Gear-Data-Exchange Format (GDE)
  • Measured value transfer via GDE communication between Gear inspection machine and Gear cutting machine
  • Optimized 3D visualization and process display
  • Available for Gear hobbing, Gear grinding, Shaping and Gear skiving machines
  • Possibility of integrating Siemens cycles for drilling, hobbing and turning operations
  • "Digital-Twin" one-to-one programming version for creating workpiece programs during work preparation
  • Support of tool changers
  • Support of the new SINUMERIK ONE control platform

The new optimized control panel, LHStation & LHMobile

With the new control panel, Liebherr is intelligently dividing the programming and operation of the machine between two system parts: The large, fixed monitor unit "LHStation" for data input and process monitoring and the standardized, mobile handheld terminal "LHMobile" with context-sensitive user guidance during set-up. Both units have a multi-touch surface as well as tactile elements for optimum operating speed and operating safety.

The control panel is designed for all gear technologies. The LHGearTec control interface is used throughout, in which the menu navigation adapts to the process. In addition to gear cutting processes, it is also possible to implement combination processes with drilling, turning and hobbing operations, which can be configured via the integrated Siemens HMI Operate interface with the integrated programGUIDE programming system. This makes complete machining of a gear possible.

The most important highlights for your start with new user ergonomics:

  • Large main screen with 24" Multi-Touch
  • Tactile numeric keypad for fast input of tool and workpiece data
  • Mobile handheld terminal with 10" Multi-Touch as standard
  • Context-sensitive views such as PLC/NC keys and program statuses
  • Reduced hardware key field for high clarity
  • Wired signal transmission for maximum safety
  • Standardized mode selector with RFID-based user recognition
  • Eight buttons or key switches, freely configurable to customer requirements
  • Two USB ports for flexible data import/export

Winner of the iF Design Award 2021

Liebherr’s operating concept LHStation and LHMobile also performed well at the iF Design Awards 2021. An international, independent jury selected the control panel for an award in the User Experience (UX) category. The design competed successfully against almost 10,000 submissions from 44 countries.
