The EDMMax 434W is a four-axis wire EDM that uses a 0.007" diameter molybdenum wire, which draws the water-based dielectric through the cut, cooling it and pulling the small chips out of the kerf at a very fast rate.

EDM Network Inc. introduced its newest fast wire EDM series, EDMMax 434W, at AM2021. The EDMMax 434W is a four-axis wire EDM that uses a 0.007" diameter molybdenum wire. EDM Network says the wire can be reused until it needs to be replaced after approximately 24-48 hours of machining. Fast wire EDMs are not flush dependent, meaning that the wire will not break in interrupted cut-off applications. The high tensile molybdenum wire draws the water-based dielectric through the cut, which cools it and pulls the small chips out of the kerf at a very fast rate. Tantalum Capacitor Tube

The EDMMax 434Ws are full, four-axis simultaneous wire EDMs that can cut programmed shapes as well as tapers up to 5° per side. There is an onboard programming system included, as well as a USB and LAN port for data loading from programming systems. 

The EDMMax 434W series is available in travels of 400 × 300 × 410 mm high, 630 × 500 × 625 mm high and 1000 × 800 × 1050 mm high, which EDM Network claims covers the largest 3D metal printers on the market today. The company offers onsite set up and training included at no additional charge.

Removing the microscopic particles made during the wire EDM cutting process becomes a key factor in maximizing cutting speed as well as attaining part accuracy and surface finish. Dielectric fluid is the mechanism for flushing these “chips” away.

Beryllium copper offers many benefts to the moldmaker and plastic injection molder, yet questions remain on how to best EDM it, which alloy to specify, where to use it, and is it safe to work with?
