UM-40A NC -

Specification

UM-40A - NC Servo Feeding Thread Rolling Machine

Upgraded to "High-Precision Servo-Driven Feed"

The UM-40A - NC is a smart thread rolling machine for high-precision and high-hardness thread processing. It replaces traditional hydraulic feed with a high-precision servo motor.

Features

  • Thru-Feed / In-Feed Dual Purpose: Switch between short parts and unlimited long workpieces with one touch on the HMI screen.

  • Smart HMI Programming: Digital setup for multi-stage feed speeds and rolling parameters. Save and reload formulas with one click.

  •  Servo Feed + Inverter Roller Speed: Servo motor controls the feed precisely, while the inverter provides stepless speed control for the roller rotation.

  •  Precision Linear Guide Ways: Upgraded to high-rigidity linear rails for smooth movement, zero crawling, and excellent thread quality.

  • Strong Structure: Made of FC-25 high-strength cast iron with tempering treatment to stay stable and precision-locked under heavy load. 
  • No Hydraulic Errors: Solves feed errors caused by oil temperature rise or leakage. Servo control ensures precise positioning without drifting.

【 Applications 】

  •  Precision screws, bolts, and set screws

  •  Automotive and motorcycle parts/shafts

  •  Mechanical hardware and knurling
