EDM Network’s mid-sized Fast Wire EDM machine, EDMMax656W, was developed for the laser powder bed fusion (LPBF) 3D metal printed market.
It was designed to quickly remove 3D printed metal parts from the larger build plates — 625 × 625 mm in size. The company notes that small molds can also be 3D printed to be used in this type of application.
The machines are not flush dependent, meaning that (unlike typical brass wire EDMs) printed parts can be randomly positioned on the build plates when cut. Cutting can also be performed approximately three to four times faster in these interrupted flush conditions with no wire breaks, the company says. The use of molybdenum wire and paper filters is said to reduce the average cost to operate to about $1.00/hr.
The machines are available in three sizes — 410 × 410 mm, 625 × 625 mm and 1,050 × 1,050 mm for very large plates. The Fast Wire EDMs are full four-axis wire EDMs that can also cut shapes and be programmed to follow the path of the support structure to reduce secondary operations. An onboard CAD software system is included to import DXF files. On-site training is included.
