CO2 2-Dimensional Laser Processing Systems ex Series Eco Changes is the

Group s stance on environmental management.

1 CO2 2-Dimensional Laser Processing Systems ex Series Eco Changes is the Mitsubishi Electric Group s environmental statement, and expresses the Group s stance on environmental management. Through a wide range of businesses, we are helping contribute to the realization of a sustainable society. K-K-02-2-C9029-A NA-1207 Printed in Japan (MDOC) 2012 New publication effective Jul Specifications are subject to change without notice.

2 Advanced Solution for Productivity and Environmental Requirements The faster processing speed and optimized control system of the ex Series reduces thin-plate processing time by approximately 20%*. The cutting-edge piercing technology allows for about a 30% reduction* in processing time of mid-thick and thick mild steel plates. *In-house comparison When not processing, the system switches to ECO mode and the resonator stops idling. Minimizes energy consumption, reducing running costs by up to 99%* during standby. Quickly resumes normal operation. Mitsubishi Electric s original resonator reduces CO2 emissions by approximately 30% compared to standard high-speed, axial-flow resonators. *In-house comparison The ex delivers maximum productivity and incorporates 2 Action Cutting which provides extremely simple operation. It also features an ECO mode that reduces power consumption during standby by up to 99%*. *In-house comparison 2 Action Cutting allows for the entire process, from job setup to parts cutting, to be completed in two simple actions. Delivers easy operation and stable performance. CAD/CAM computer, connected via network, is a great aid for operators on the shop floor. 3 4
