UNIOR – Type FPZ-250

Reliable performance and technical solutions offer a lot of advantages

  • Time between two processing procedures is shorter than 1 second (tp < 1 sec)
  • Fast removal of chips during dry processing (top mounted clamping device)
  • Modular system of upgrading the processing units
  • Flexibility of the machine
  • »pick-up« clamping of workpiece
  • Possible processing from five different sides
  • Possible simultaneous four-axis processing
  • Spindle with clamping device for the workpiece vertically
  • Compact construction as a whole unit
  • Simple connection into a system

Their own development and manufacturing of flexible processing cell FPZ-250 ensures

  • Cycle time of processing is in average 30 % shorter compared to the processing centers
  • Fewer operations of the machines are needed
  • Switch over of the workpieces with a change of clamping device,
  • At small-scale production it is possible to save on one ore more machines with the integration of FPZ machine

Operation of the machine

A fixture is placed on vertically positioned clamping device. In the pick-up procedure, the workpieces are driven from the pallet system into the processing area. Different spindle subassemblies are placed in the processing chamber. By passing the slug from tool to tool, individual technological operations are executed to the subsequence determined by the recorded in the NC program. During each individual processing time, automatic exchange and preparation of tools is taking place on at least one spindle subassembly.

Advantages in comparison with machining center

  • Time between machining operations lower than 1 sec
  • No problems with particles at machining in dry conditions (jig hanging)
  • Pick-up system of workpiece clamping
  • Easy to connect into system
  • Machining from 5 sides possible
  • Simultaneous 4-axis machining possible
