Wide range of configuration options for a wide variety of sanding operations

Covers a wide range of workpieces up to 150 kg

High drive power of the grinding disc ensures high productivity

Flexible for maximum customer orientation

The KELLENBERGER 100 offers a wide range of configuration options for a wide variety of grinding operations and thus enables a strong customer focus. With a center height of 200 mm, center width of 600/1,000 mm and generous X-axis strokes of 365 mm and Z-axis strokes of 750/1,150 mm, the machine covers a wide range of workpieces weighing up to 150 kg. The automatic 1° indexing axis with high positioning accuracy and the direct-drive internal grinding spindles up to 90,000 rpm are further features. The large drive power of the grinding wheel results in high productivity, while the new Z-guide ensures high profile accuracy. The C-axis with direct drive provides greater accuracy for non-circular grinding.

The technical highlights of the KELLENBERGER 100 include an innovative compact grinding head (10 grinding head variants, 11.5 kW drive power, 500 mm wheel, up to 63 m/s, HF spindles for internal grinding incl. diagonal and tandem arrangement), a collision-free universal head with three tool and one measuring position as well as a new measuring probe arrangement without swivel mechanism for increased measuring accuracy. A synchronous tailstock allows the complete machining of shafts without a driver, i.e. the workpiece can be machined completely over its entire length.

The reinforced casing allows larger grinding wheel diameters for internal grinding. Operator guidance is via an intuitive 19″ touchscreen interface on the latest FANUC 31i-B CNC control system. The innovative BLUE Solution software enables even inexperienced operators to program quickly and intuitively.
