Applications

Where It Works

  • Electrical panel builders and bus bar fabricators making accurate, repeatable copper bar bends across a range of bar lengths and widths

Features

Built In

  • Fully customizable, easily programmable CNC controls built for copper bar work, with a color touch-screen and a library of canned busbar shapes.
  • An integrated encoder measures the bent angle during the operation and automatically rebends, compensating spring-back for consistent, accurate bends.
  • Two models, the 22-ton 220 CNC-WP and 42-ton 420 CNC-WP, bend up to 150 x 16 mm and 200 x 20 mm, and pair with Boschert CU punching through METALIX CAD/CAM.
