The features of UM-50 / 50A: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.
