UM-3DX-NC 3-roll threader designed specifically for hollow tubes. By using NC servo feeding and a 120-degree three-axis pressure system, it delivers high roundness, eco-friendly performance…..

Key Advantages

  • NC Servo FeedingReplaces old hydraulic systems with a servo motor. It reaches micron-level precision and stays accurate without being affected by oil temperature.

  • Digital Control Panel: Adjust spindle speed,and support multi-stage feeding to make your dies last longer.

  • Eco-Friendly & Quiet: Eliminates hydraulic oil leaks, runs quietly, and meets modern green factory standards.

  • Durable Drive System: Gears are heat-treated and precision-ground. This means zero backlash, high wear resistance, and reliable heavy-duty performance. 

Suitable for

  • Automotive & Bicycles:Hollow shock absorber piston rods, steering shafts,and bike hubs.

  •  Plumbing & Hardware: Copper or stainless steel pipe connectors and quick-connect fittings.

  •  Construction & Heavy Industry: Hollow screws, scaffolding adjustment rods, and hollow drive shafts.
