New flexibility supporting invention
CNC punch machines are nothing new, but the Greub G3 press represents a profound change in the way that new punching machines and stamping tools are created. Simple and therefore less expensive tools can be designed for small and medium production runs
that are better adapted to the customised products required by the market. In the case of progressive machines, for example, standard modules for mounting punches and dies
that can easily swapped in and out as required, can easily be integrated in the die sets.
The FANUC numerical controller in combination with an optical or laser scanner controls the strip feed function with extremely precision. Likewise, the rate of descent, the approach and cutting speeds as well as the depth of penetration can be controlled to two decimal places. The relationship between striking rate, the thickness to be cut and the strip feed rate is also fully programmable. Operator safety is assured at all times, with all security features automatically taking into account the press operating status.
The user-friendliness of the FANUC controller and its multifunctional integration capabilities (touch screen, 4 channels, 24 axes) give free rein to the imagination of designers. For manufactures in the watchmaking, micromechanical and mechatronics industries, the ability to produce parts in small series, with high repeatability and at mass production costs, opens up completely new vistas.
