Universal Grinder Offers 10 Wheelhead Options
Hardinge offers the Kellenberger 100, a high-performance, economical grinder for universal grinding.
Hardinge offer. 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.
Because creep-feed grinding is essentially a milling process, why not use a VMC? A grinding machine supplier describes how a VMC platform can make creep-feed grinding more effective.
It sounds like a contradiction in terms-between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time reductions of 45 percent over separate grinding operations.
The double-disc grinding process is consolidating its position in automotive applications but is moving into other industries. Double-disc grinders are now easier to operate, and they have added capabilities for control flexibility, precision process control, faster changeovers, and grinding of nontraditional materials.
