The features of UM-75 thread rolling machine:

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