Pneumatic workpiece ejector

The pneumatic workpiece ejector pushes the workpiece from the chuck automatically. Its depth can be adjusted flexibly by means of a special retaining mechanism and it can be positioned in the machine exactly as required for the workpiece. This automated function increases process security and reduces cycle times.

The Vario Flex can also be used as a basic end-stop for coolant wash or air flush. The pneumatic spring is removed and a feed tube is attached. The optional workpiece-specific end-stop with holes for the wash and air-flush can then be mounted directly on this flexible interface.

Time can be saved using the standardised end-stops. Set-up times are reduced and the user always has the right end-stop ready to hand. Whether to use Vario Quick or Vario Part is just a matter of preference.

For precise, rigid clamping, Hainbuch recommends using the Vario Part system. It works on the same principle as a gauge block, and its height can be finely adjusted in 1mm steps with gauge discs. With an axial run-out of < 0.02mm at the part of the end-stop that touches the workpiece, Vario Part is suitable for machining finished parts.

The Vario Quick variant is intended for fast, flexible clamping. It has a precise, trapezoidal thread screw to allow the clamping length to be adjusted quickly. A half-turn is equivalent to an axial adjustment of 1mm. Hainbuch also offers end stop blanks for workpiece or front end stops.
