UM-75 hydraulic thru feed type thread rolling machine is the biggest model in our factory currently.  The controlling of UM-75 is with PLC program and HMI systems.  It is easier for the step adjustments as required. 

The features of UM-75 thread rolling machine:

  1. Thru feed and in-feed (plunge feed) both available:  The rolling time and the rolling length can be adjusted by the sensors.
  2. Powerful rolling pressure : The slide way feeding is driven by hydraulic unit, precision in positioning, owerful without any distortion.
  3. Solid structure:  heat treatment of high tension cast iron FC-25 frame is durable
  4. Steady feed motion: Ground square  slide way can avoid the jumping , vibration and wear away.
  5. Perfect transmission: The ground-thread worms with heat treatment progress can be matched completely and smoothly with phosphoric brone worm gears.
  6. Specially suitable for: Long length screws, ACME screws, Ball Screws, machine parts, tool and automobile / motorcycle parts.
