Technical Specification
Technical Description of the Base Machine
In contrast to cylindrical grinding machines for lighter machining, where the workpiece is often rotated by a tailstock drive, this machine type features a rotating grinding wheel with a feed movement.
This machine enables internal and external grinding of heavy workpieces between centers. The rotation of the workpiece is carried out via the headstock.
