Specification

UM-3DX 3-Roll Thread Rolling Machine

 

UM-3DX is the powerful version of the 3-roll series, designed for rolling threads on hollow tubes and pipes. It uses a 120-degree 3-roll system to squeeze the tube evenly from three sides. This stops the tube from flattening or bending under pressure, making it perfectly round and straight.

Key Features

  • 120° Even Pressure: The tube receives equal pressure from all sides. This prevents deformation and keeps the workpiece perfectly round.

  • Smart Touch Screen (PLC + HMI): Rolling time and part counts can be easily set on the screen. It makes setup and troubleshooting fast and simple.

  • Spindle Gearbox with Mechanical Speed Adjustment: It is easy to set the rotation speed for different tube sizes and materials. The gearbox features high-quality ground gears manufactured completely in-house. This strict quality control ensures smooth, quiet, powerful, and highly durable operation.

  • Two Rolling Modes: Both Thru-feed (for long tubes) and In-feed (for short parts) are available on one machine.

  • Safe 24V Design: The control system uses a safe 24V low voltage. This protects operators from electric shocks, even in wet factory environments with cutting oil.

Applications

  • Automotive & Bicycle Parts: Hollow drive shafts, tubes, and lightweight bike hubs.

  • Hydraulic & Plumbing Parts: High-pressure pipe joints, cooling pipes, and lighting tubes.

  • Construction Parts: Scaffolding screws and structural pipe joints.

*Specially designed for tubular processing. Equilateral triangle supports running to assure the roundness.

 

*Equilateral triangle supports rolling for improving roundness, concentricity and vertical degree.

 

*Driving by hydraulic unit : featuring in easy operation and powerful pressure.

 

*The transmission gear with grinding shape : featuring in noise-free, durable and precise transmission.

 

*Particularly applied to the tubular thread procession, such as oil connectors, bicycle, automobile and motor vehicle parts, radiating pipe etc.
