The Vario Flex poneumatic workpiece ejector is the third variant that joins the vario part and vario quick end-stop systems family. According to Hainbuch, Vario Flex ejects the workpiece from the chuck automatically. It can be adjusted flexibly with a retaining mechanism and can be positioned in the machine as required by the workpiece. This automated function increases process security and reduces cycle times.

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

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

The Vario Quick variant is, on the other hand, good 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 1 mm. Hainbuch also offers end stop blanks for workpiece or front end stops.

The all-in-one workpiece ejector and basic end-stop for connecting a wash-out or air system will be among the exhibits at AMB, in Hall 1, Booth E10.
