Manufacturer of clamping and gripping devices for turning and milling machine tools, including drill chucks, lathe chucks, power chucks, vises, tool clamping systems, live centers, and automation grippers. Headquartered in Sontheim an der Brenz, Germany, founded in 1909.
Tool holders connecting drilling tools to hand-operated and stationary drills, machine tools, and boring machines. Series span up to 26 mm clamping range with concentricity down to 0.05 mm.
Lathe chucks with individually adjustable jaws for high-force initial machining, used up to 1.3 m clamping diameter in rail work and up to 5 m diameter with up to 50 tons clamping force per jaw.
Automated chucks for cutting and grinding on machine tools, jaw-actuated via hydraulic or pneumatic cylinders, in 2- or 3-jaw, through-hole, quick-change, and draw-down designs.
Workholding vises for milling and drilling, with clamping force up to 100 kN for universal, 55 kN for conventional machine-tool, and 50 kN for side-mountable models.
Standardized SK and HSK tool interfaces for rapid tool changes in CNC milling and machining centers, including automatic/manual clamping sets and pallet clamping heads.
Parallel, centric, and custom-contour grippers plus swivel units for automated workpiece handling, used for loading and unloading machine tools and for positioning parts in assembly systems.
Sensor-equipped clamping jaws that measure clamping force in real time during turning and milling, for OEM integration or aftermarket retrofit on lathes.
Precision centering tools that counter-clamp workpieces on turning and grinding machines, offered as standard, solid, revolving-taper, and interchangeable-insert variants.
