Our best estimate for a sinker edm (ram edm) in this class — not a quote from Makino. Configuration moves it a long way.

Overview

The Makino EDAF2 is a mid-size sinker EDM with 350 mm (13.78 in) of X, 250 mm (9.8 in) of Y and 250 mm (9.8 in) of Z, a 550 × 350 mm (21.65 in x 13.78 in) table and a 700 x 500 x 300 mm (27.5 in x 19.7 x 11.8 in) work tank. It takes workpieces up to 500 kgs (1,100 lb) and electrodes up to 75 kgs (165 lb).

The layout is built around a stationary worktable with a programmable rise-and-fall work tank. Because the table does not move, a heavy mould insert stays where it was set, and lowering the tank gives open access for loading and indicating. Makino says the design also simplifies fitting an ATC and automation for unmanned running. Where the 300 mm tank depth is not enough, an optional 50mm (2.0") or 100mm (4.0") table-down configuration adds depth.

Thermal stability is handled in two ways. The dielectric reservoir is built into the base casting, which saves floor space and steadies the machine's temperature, and the Y-axis and Z-axis structures are actively liquid cooled. For long burns on precision cavities, that is what keeps the electrode position from drifting as the shop warms through the day.

The generator uses Makino's adaptive power control, and the operator can choose dedicated settings such as HyperCut, SuperSpark™ IV and ArcFree for different kinds of work. The control is Hyper-i. A fire extinguishing system and a U/V flame sensor that watches the process are built in as standard, which a shop needs before it lets the machine run unattended.

The EDAF3 is the next size up, with 450 mm (17.7 in) of X and a 700×500 (27.5 in x 19.7 in) table, for moulds that outgrow the EDAF2's 350 mm (13.78 in) of X.

Strengths & Limitations

Strengths

Electrodes up to 75 kgs (165 lb) and workpieces up to 500 kgs (1,100 lb)
Stationary worktable with a programmable rise-and-fall work tank for setup access and automation
Dielectric reservoir in the base casting plus active liquid cooling of the Y-axis and Z-axis structures
Optional 50mm (2.0") and 100mm (4.0") table-down configurations for deeper work
Standard built-in fire extinguishing system and U/V flame sensor

Limitations

Z travel of 250 mm (9.8 in) limits the depth of cavities and electrode stack-ups
Tank depth of 300 mm needs the optional table-down configuration for taller parts
Makino's table gives no peak machining current for the generator
350 mm (13.78 in) of X; larger moulds need the EDAF3 with 450 mm (17.7 in)

Best For

Mould and die cavities on parts up to 500 kgs (1,100 lb) Heavy electrodes up to 75 kgs (165 lb) Unattended sinking with an added ATC or automation Long precision burns that depend on thermal stability

Frequently Asked Questions

01 How large a workpiece fits in the EDAF2?

The table is 550 × 350 mm (21.65 in x 13.78 in) and the work tank 700 x 500 x 300 mm (27.5 in x 19.7 x 11.8 in). Workpieces can weigh up to 500 kgs (1,100 lb). An optional 50mm (2.0") or 100mm (4.0") table-down configuration adds tank depth for taller parts.

02 Can the EDAF2 run unattended?

Makino says the stationary table and rise-and-fall tank simplify the integration of an ATC and automation systems to extend unmanned operation. A built-in fire extinguishing system and a U/V flame sensor that monitors the process are standard.

03 How does the EDAF2 keep its accuracy over long burns?

The dielectric reservoir is integrated into the base casting, which improves thermal stability, and the Y-axis and Z-axis structures have active liquid cooling to keep the whole machine at a stable temperature.

04 What machining settings does the EDAF2 offer?

Makino's generator and adaptive power control are paired with dedicated settings such as HyperCut, SuperSpark™ IV and ArcFree, which give the operator options for a wide variety of work. The control is Makino's Hyper-i.

05 How does the EDAF2 compare with the EDAF3?

The EDAF3 is larger, with 450 mm (17.7 in) of X, 351 mm (13.8 in) of Y and Z and a 700×500 (27.5 in x 19.7 in) table. The EDAF2 has 350 mm (13.78 in) of X, 250 mm (9.8 in) of Y and Z and a 550 × 350 mm (21.65 in x 13.78 in) table.
