The machine is also capable of processing hollow back adhesive, which is 30 percent bio-based (in accordance with

A unique feature of the QS 860 to date is that a second

machining spindle can be used, which can erode contours

using a peripheral electrode.
This machining is carried out in one tool set-up together
with the standard free surface machining. This significantly
reduces set-up times and increases the quality of the PCD
saws, as no reclamping is required.

The QSF 860, on the other hand, is designed for processing
