The Alpine ETR Series CNC electric tube benders feature touch screen controllers, a triple stack tooling design with 4 axes (Y- Feeding, B-Rotation, C-Bending, X- Horizontal with horizontal bend head shifting for tooling changing) and are driven by an A/C servo motor. The ETR Series tube benders equip both draw-bending & push-bending function in the same tool stack. The electric-driven rotary draw bending arm performs with high accuracy and reduced electrical consumption. Alpine machines also feature a patented planetary gear driven bending head. This patented bending head has a compact and rigid design that provides highly accurate bending results and at the same time minimized machine interference. The planetary gears in the bend head also provide speed reduction and high torque transmission. These tube benders are perfect for application in the furniture, automotive, motorcycle, fitness equipment, aerospace industries and more.
