CNC EDM Machine
The company announces the availability of a new model, the DB 300 CNC EDM machine. This model incorporates a new high speed pulse technology, which is based on faster head action and servomotor control. This series is said to be more efficient, especially in jobs that involve difficult flushing applications. With the company’s Erosion Expert System, deeper machining is achieved while eliminating flushing problems (which results in the manufacturing of higher precision parts).
The EDM machine can machine deep ribs faster with more precision, as the CNC incorporates technology tables specifically for the machining of ribs. The company says the automatic program generation incorporates conversational operator input to produce the best-suited program for the type of rib or cavity being machined. Also, the Expert Erosion System controls the entire machining of a workpiece, from roughing to final finishing. The machine can operate around the clock in an unattended mode.
The EDM machine incorporates automatic strategy to produce the program needed for the optimal erosion process. By inputting minimum data, the CNC analyzes the optimal erosion process showing the number of requested electrodes and their undersizes and automatically generates and executes the program. With automatic strategy, the user can add his own information to the CNC, creating his own technology tables with automatic strategies. Also, the systems reduce the training time of the operator.
According to the company, other features of the EDM machine include: simultaneous four-axis machining for a large number of functions; a mechanical structure head design to eliminate vibrations produced by the fast accelerations and decelerations of the EDM machine (this ensures the manufacturing of precision parts); multiple applications through the functions incorporated into the CNC; angular orbiting; a standard fine finish mode (VDI = 0); excellent homogeneous surface finishes obtained on large areas; and compatibility with Hirschmann, Erowa and System 3R tooling systems.
The base, column, head and both X and Y tables are constructed of stabilized fine-grained cast iron blended with graphite in a symmetrical design to keep thermal deformation down to a minimum. Also, a paper cartridge filtering system is standard on the machine. The Dielectric Filtering System, which offers more than 10,000 working hours of filter element life, is offered as an option.
Electrical discharge machines, both wire and ram type, have undergone rapid improvements in capability, economical operation, speed and flexibility. New applications are continually emerging as shops discover the advantages of this process.
Additives, machine settings, workpiece materials and current technology are factors in avoiding common problems with unwanted rust and surface defects.
Modular workpiece fixturing plays a vital role in this shop’s quest to win larger, more difficult wire EDM jobs.
