The Kellenberger 100 universal grinder from Hardinge is said to offer a good price-to-performance ratio. The machine combines the capabilities of the Vista and Vita machines as well as the Tschudin T25, the Jones & Shipman Ultramat CNC and Ultragrind 1000. It offers diverse configuration options for a range of grinding operations for customers looking to optimize production costs, the company says. 

The Kellenberger 100 has a tandem grinding wheelhead in compact and collision-free construction with the motor spindle. A reinforced casing allows for larger grinding wheel diameters for internal grinding. There are 10 wheelhead variations to establish optimal machine layout based on the parts to be processed. 

Other benefits of the machine include increased productivity with higher grinding wheel drive power; extended X- and Z-axis travels as part of a new dressing concept; improved profile accuracy with redesigned Z-axis guideways; a high-precision B axis with direct drive and absolute measuring system; and increased accuracy for noncircular grinding with the help of a direct-drive C axis. 

Equipped with a FANUC 31i CNC, the grinder features a user-friendly and ergonomic design with an intuitive operator guidance system on a touchscreen panel. The user interface is available in two different versions: Blue Solution, an intuitive touch programming system, and Red Solution, featuring extended graphic programming.
