Boschert Precision Machinery offers a variety of Stierli-Bieger options for copper bending:
300 NC 300 CNC W 300 CNC WP
Description:
The Stierli-Bieger 300 NC, 300 CNC W, and 300 CNC WP bending centers are highly productive and versatile machines with modern 1- or 2-axis control. All models utilize easy to follow operator instructions on a large, easy to read flat screen. The NC control can store up to 200 programs with 10 reference positions and the CNC control can store up to 600 programs with 10 reference positions.The large and spacious work platform of the 300 NC, 300 CNC W, and 300 CNC WP gives maximum stability for ease of bending larger components.
The automatically lubricated and fully guided hydraulic cylinder is maintenance free with no open slot or guide.
Each model can be operated by using a foot pedal or remote hand control.

| The stroke control can be corrected in the program at any time in +/- 0.004" increments to allow for difference in material.. | The bend angle can be corrected in the program at any time in +/- 0.1 degree increments to allow for differences in material. | Material spring back is automatically measured and corrected by the CNC by re-bending the part. |
| Reference positions are automatically recorded using the "teach in" button. | Bending angles can be programmed. The length of stroke, measure of gauge, and the bend allowance can be calculated by the CNC. | Bending angles can be programmed.
