NEW VISTA WSH SERIES FEATURES

  • Complete functional Units, supplied with motor, drive, sensors and cables.
  • Models available for thread verification and thread chasing. Same Unit can be used for both internal and external threads.
  • Self-feeding. Spindle quickly advances to engage the thread.
  • Rotatable collar is used to quickly set the torque limit. Graduated fingerwheels set thread depths.
  • For thread verification models, a sensitive high speed drive allows the thread member to stop in case of missing or improperly formed threads. This creates a “reject” signal.
  • Missing holes and/or missing studs are instantly identified as rejects.
  • Will follow existing threads. Won’t cut out-of-phase thread or damage threads at the mouth of the hole (or at the end of a stud).
  • Will chase out (or verify) full thread depth in blind holes.
  • Will work right up to a shoulder (for studs).
  • Will not jam or stick in bad or short threads.
  • Does not subject the part (or the tools) to high force or torque levels.
  • Quick to set up and use. Will mount in any orientation.
  • Instructions provided for how to mount, align and operate.
