Single-spindle gundrilling machine
The UNE6-750-CR single spindle gundrilling machine offers everything needed to gundrill the most difficult medical workpieces in any shop environment.
Geared towards precision instrumentation work, this machine utilizes a counter-rotating workpiece headstock to achieve extremely high concentricity with a wide range of depth-to-diameter ratios.
Independent dual-spindle Gundrilling Machine
operated from single side
The most capable twin-spindle machine in the industry, the UNE6-2i-750-CR is the solution for complex, small-diameter medical instrument gundrilling. Sequential drilling operations common in surgical instruments are completed on one machine.
Fully independent dual spindle operation is accessible from a single side of the machine making the ideal one-piece flow possible when manually loaded.
UNE6-2i-750-CR with Automation
Independent dual-spindle gundrilling machine
with robotic workpiece automation
The UNE6-2i-750-CR with robotics makes gundrilling difficult, extremely precise surgical instruments for the medical industry possible and automatic. The process reliability of this machine opens the door to fully-automated production of these workpieces allowing lights-out gundrilling of the most complex components
Embedded robotic automation services both spindles and transfers workpieces between them. Interchangeable workpiece tray systems fit different workpiece types and are compatible with irregular OD Swiss-turned blanks. Rear mounted automation allows setup and operation from the front of the machine without interference from the automation.
