Depaneling SAR Compact

Economical depaneling system SAR-Compact

The SAR-Compact depaneling machine is an attractively priced solution for small to medium-sized batches with different to high product variations. The very high price-performance ratio of this machine was not checked by high-speed processes, but by a consensual value-analytical approach, which enables you to invest in your own machine while at the same time replacing all functions and that of the automotive industry.

Despite the low investment, the machine uses the latest drive technology and linear motor technology with high precision in the directions x, y and z. Nor are there any compromises in terms of flexibility. Furthermore, our workpiece carrier solutions such as MAGNOPLATE and "do-it-yourself" can be used to enable the customer to work efficiently and flexibly in high-mix production.
Simple operation due to simple menu navigation, CAD / CAM programming and teach function.

Furthermore, our Werkstückträger-solutions can be used to enable the customer to work economically and flexibly in high-mix production.
