• At the TUBE 2006, RSA presents for the first time the sawing center RASACUT MC as a benchmark for the new generation in the sawing and processing technology for tubes and sections (Fig. 14). The central point of the sawing center, which is designed on the proven modular principle, is a computer assisted system control which facilitates a clearly simplified operation and no longer requires any CNC knowledge. In operation, the noise emission is under 85 dB(A).
