Swiss grinding machine specialist Kellenberger presents the new KELLENBERGER 100 machine concept

In its anniversary year 2017 the innovative strength of Kellenberger and, by extension, of the Hardinge Grinding Group as a whole, is on full display. The task presented to the engineers in St. Gallen, Switzerland, was to develop a platform solution on which diverse machine concepts could be realized with a strong customer focus. 

With the completely newly developed KELLENBERGER 100 platform solution the high-performance, economical grinder segment in the group is being modernized to make it fit for the future. Kellenberger’s Vista and Vita machine model ranges, the Tschudin T25, and the Jones & Shipman Ultramat CNC and Ultragrind 1000 were integrated in the KELLENBERGER 100 platform concept.

In terms of functionality the new platform concept goes far beyond the possibilities of the machines named above and delivers the most diverse of configuration options for the widest range of grinding operations. Because of the modular solution on one common platform and the new assembly concept designed to reduce throughput time, it was possible to optimize production costs for the machine and ensure an excellent price/performance ratio. Numerous standard options put the finishing touch on the machine variety.

The user-friendly and ergonomic design of the KELLENBERGER 100 machines will feature a new, simple operator guidance system on an intuitive touchscreen panel. The machines are equipped with the latest Fanuc 31i CNC controls with 19″ touchscreen, optionally also with newly designed cycle programming or workpiece-related graphic programming.

The Fanuc 31i controls:

  • Replacement for KEL-EASY, with intuitive touchscreen operation
  • Consistent support for the operator throughout, in newly designed user interface
  • Expanded range of functionality
  • Integrated automated technology calculation
  • Context-sensitive help images
  • Online operation and maintenance instructions
  • No ISO programming skills necessary
  • Optionally also available with familiar Fanuc 31i applications

Three important features distinguish the new KELLENBERGER 100 machine series:

Innovative, collision-free, compact wheelhead solution:

  • New tandem wheelhead in compact construction with motor spindle. Reinforced casing for larger grinding wheel diameters for internal grinding
  • Choice of 10 wheelhead variations for optimum layout of the machine based on the components to be processed

Enhancement of performance parameters:

  • Higher grinding wheel drive poweràincreased productivity
  • Newly designed Z guidewayàhigher profile precision
  • C axis with direct driveà higher precision for non-circular grinding

Service-friendly machine concept:

The service department was involved in the optimization of the machine concept. This means that faster maintenance and service operations and optimum accessibility of maintenance-intensive components are assured.

A machine in construction length 1000 will be showcased at EMO in Hannover.
