Workpiece carrier with round recess in the processing position. Thanks to this gap in the design of the HZEO, the workpiece can also be processed from below.

 

 Information:

Available as an additional accessory, we can supply holding-down clamps that also precisely position the height of workpiece carriers and prevent them from being unintentionally withdrawn during or after a processing operation.

(See HZE with holding-down clamps.)

Open lift centring device (HZEO)

Open lift centring devices are installed in the STEIN 300. In combination with the STEIN 300, HZEO units facilitate the following operations:

  • The precise positioning of workpiece carriers (and thus the workpieces they hold).
  • Access to workpiece carriers from above and from below.
  • Lifting and support of workpiece carriers during forceful processing operations on the workpiece.

 

Workpiece carriers are brought to a halt by a stopper and pre-positioned. The entire lift centring device is then raised by pneumatics. The centring bold engages with the centring bushes on the workpiece carrier and precisely positions it with an accuracy of ┬▒ 0.02 mm. The entire workpiece carrier rests firmly on the base plate of the lift centring device and is ready for processing.
