Connection and Control PC-CNC Systems

Starting from 1989, Spectrum Technologies design and develop connection and monitoring technologies, wired and wireless, for machine tools CNC.

Multi-DNC™ is a communication and management system for CNC programs, that allows loading, unloading and sending block to block to multiple simultaneous Numerical Controls. The package includes advanced features for comparing files, editor and backplotter.

Multi-DNC™ can be easily connected to CAD-CAM systems, using Ethernet network, and is also available in client-server configuration.

Multi-DNC™ is integrated with a powerful machine tool monitoring system, Machine Event Monitoring™ (MEM), which shares a single database for storing events, avoiding the need to duplicate hardware and software normally required to perform two functions (MEM and DNC).

Multi-DNC™ uses multiport serial card devices and wireless / wired ethernet devices even in a mixed configuration.

Multi-DNC™ is a flexible, easily expandable and configurable system, which ensures a fast return on your investment and a very long life of the system thanks to its continuous updates.

Multi-DNC™ is English localized and directly supported in Italy by DueZero and worldwide by Spectrum International Resellers.
