Ercolina TB80 Mandrel Bender

Ercolina’s Semi-Automatic TB80 Mandrel Bender is ideal for prototype or small production mandrel bending applications. The bending head adjusts horizontally to maintain a centerline radius allowing the table to remain stationery.

Key Features of the Mandrel Bender TB80

  • Mild steel tube capacity 3″ (.125 wall)
  • Stainless tube capacity 3″ (.083 wall)
  • Square tube capacity 2½” (.083 wall)
  • Pipe capacity to 2½” Sch. 10
  • Maximum bend radius 11.8″
  • Bend to CLR as small as 1.5D
  • Control swings out to offer easy access to manual and auto operating modes, system diagnostics and multiple languages
  • Unlimited storage of bend programs, material library and job information (optional)
  • Touch screen displays absolute (ABS) or incremental (INC) positioning with inch or metric readout
  • Programmable C axis with manual Y and B positioning
