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.
In vertical grinding, the workpiece is held upright in a rotary chuck with the grinding spindle overhead. This configuration can improve roundness, facilitate single-setup processing and prolong the life of the machine. Loading and unloading may gets easier, too. Workpieces with relatively large diameters and short lengths benefit the most from vertical grinding.
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.
If one must pick a manufacturing specialty, grinding carbide might not be the first choice because it’s perceived to be very difficult. RPM Carbide Die, however, has worked the material for nearly 40 years and, as specializing seems increasingly to be the order of the day, this northern Ohio shop is in a good position to thrive.
