Greater holding power

For customers that may already be using high-end solutions such as the Hainbuch SPANNTOP range, the new TOPlus permits 25% higher clamping forces whilst using the same clamping cylinder that is used to actuate the SPANNTOP range of chucks. The TOPlus incorporates a pyramid arrangement of glide surfaces to make this possible. The clamping head rests with full-surface contact in the TOPlus chuck body. This even applies with large workpiece tolerances. 

This geometry ensures the TOPlus line is less sensitive to contamination than Hainbuch's previous chuck/clamping head solutions. This enables the TOPlus to provide concentric precision of 0.015mm for chuck sizes to 100m bar capacity.

For raw materials, cast and forged parts and also fine-particle non-ferrous metals such as brass, the new TOPlus excels. Additional benefits include the elimination of radial displacement between clamping head and chuck body, which makes it resistant to contamination. Furthermore, the chuck incorporates vibration damping technology that also enables the end user to improve surface finishes and precision levels.
