# Makino EDNC20

Hardware · `EDNC20` · verification: source checked

The Makino EDNC20 is a ram-type sinker electrical discharge machining (EDM) machine with a stationary worktable and a programmable rise-and-fall front door. It uses an HS-Rib high-speed Z-axis for jump motions and a Hyper-i control for programming and operation. The machine is designed for large workpieces and includes a dielectric reservoir integrated into the base casting.

## Study notes

- The document describes the EDNC20 as a sinker (ram) EDM machine.
- The HS-Rib high-speed Z-axis can make jump motions up to 20 m/min over an 800 mm stroke.
- The document states jump capability can reduce cycle time by up to 60 percent compared with traditional processes.
- Extended-stroke and extended-work-tank versions add 200 mm of X-axis stroke and 300 mm of Y-axis stroke.
- Extended versions accommodate parts up to 2,800 mm x 1,800 mm.
- The worktable is stationary; the front door is programmable rise-and-fall.
- The dielectric reservoir is incorporated into the base casting.
- ATC capacity options stated are 8, 16, and 32; the ATC is outside the work tank.
- The Hyper-i control has a 24-inch class touch screen, digital manuals, and E-Tech Doctor functions.
- The table lists parenthetical travel values of 2,200 mm X, 1,000 mm Y, and 800 mm Z.
- Tank size is 2,800 x 1,600 x 1,050 mm.
