A mass of screws can be precisely made by thread rolling machines with thread rolling dies. “Cold forming” is the most appropriate description of thread rolling progress. Place a round material blank in the between of thread rolling dies. The die thread penetrates the blank surface to form the thread roots and displaces material outward form the crest. This is the basic theory for thread rolling.

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.
