For certain applications, especially high volume requirements, our proprietary 'Multi-Lead/Multi-Servo' EDM Systems can change the economic equation, and allow EDM to challenge other machining processes.

The primary cost driver of EDM is machining time. For certain applications, EDM is the only alternative, but it is slower than conventional machining. Machining time may be further increased by surface finish requirements. Tolerances may dictate additional passes to accurately finish to size.

On the other hand, the nature of EDM allows multiple parts to be machined simultaneously. The efficiency of the process may be greatly improved by innovative fixturing of multiple parts and electrodes. ABET has specialized in this this type of solution for 35 years. Using this method, we have machined parts in quantities of tens, hundreds and thousands.

The limitation of this approach is that on a typical EDM machine, one power lead and one servohead is available. In order to increase throughput, additional machines may be required. This need for additional capital equipment is another cost driver. Another factor is that a typical EDM machine is sized to handle a wide variety of jobs, from small parts to relatively large pieces - most commonly heavy molds and dies.

To overcome this limitation, ABET has developed the expertise to design and build complete EDM systems. Based upon the unique requirements of each application, we are able to configure a system for optimum machining efficiency. The system will include the appropriate combination of multi-part fixturing, multiple power leads and multiple servoheads. Our unique approach to Production EDM changes the economic equations, and allows us to compete with conventional machining in cases where EDM might have been ruled out.
