The Spanntop mini is said to have a mass reduction of 38%, a 30% length reduction and a 30% smaller chuck diameter.

Hainbuch says that, in essence, the Spanntop mini will significantly reduce the interference contour, improve tool accessibility, reduce mass on the machine spindle bearings and reduce energy requirements. Available in six different sizes that include 32, 42, 52, 65, 80 and 100mm bar size, the Spanntop mini can help reduce cycle times and component production costs.

The Spanntop consists of a vulcanised clamping head with hardened steel segments, a variable spindle flange length and a through-bore for bar work after disassembling the base stop. The unit also has a fixed base end-stop with central mounting thread for workpiece specific end-stops, a mounting thread for easy drawtube connection to most machines and an easy end-stop removal with external screw.
