Our best estimate for the Makino EDNC-20 is $700,000 - $1,000,000. This is an estimate for a sinker edm (ram edm) in this class, not a quote from Makino; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/makino-ednc-20#price; the request is passed to Makino or an authorised dealer.
The table lists X as 2,000 mm (2,200 mm), Y as 700 mm (1,000 mm) and Z as 600 mm (800 mm) without labelling the bracketed figures. Makino refers to several EDNC-20 configurations, and its HS-Rib description gives 31.5” (800mm) of stroke, so ask which configuration delivers which strokes.
With the HS-Rib high-speed Z-axis it achieves jump motions up to 20 m/min over its 31.5” (800mm) stroke, and Makino says this cuts cycle time by up to 60 percent against traditional processes. Rapid traverse on the axes is listed at 2 m/min (79 in/min).
All configurations use a stationary worktable with a programmable rise-and-fall front door that opens for part setups. The table is 2,500 x 1,200 mm (98.4 in x 47.2 in) and supports parts weighing up to 22,000 lbs. (10,000kg), so crane access to the front of the machine matters.
The EDNC-17 has 1,700 x 1,150 x 800 mm (66.9 x 45.3 x 31.5 in) of travel and a 2,000 x 1,350 mm (78.7 in x 53.2 in) table. The EDNC-20 has a 2,500 x 1,200 mm (98.4 in x 47.2 in) table, more X travel and less standard Y, and loads through a front door. Both are rated for 10,000 kg (22,046 lb).
