How much does the Makino EDGE2i cost?
Estimated price range
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 EDGE2i is a compact sinker EDM with 300 x 250 x 250 mm (11.8 x 9.8 x 9.8 in) of travel, a 500 x 350 mm (19.7 in x 13.8 in) table and a 500 kg (1,100 lb) workpiece rating. Its generator delivers 40A as standard, with 80A as an option, so out of the box it is a machine for fine detail and small cavities more than for heavy roughing.
Much of what Makino lists for the EDGE2i is aimed at running without an operator. The automatic tool changer is built into the machine structure underneath the X and Y axes, and the table lists its capacities as 4,8,16. An integrated Flame Sensor and Fire Suppression system is standard, the EDGEi-Series comes standard with a dielectric chiller unit, and the dielectric reservoir is part of the base casting.
The work tank is 650 x 450 x 300 mm (25.6 in x 17.7 in x 11.8 in), a 4-sided programmable rise-and-fall design, and the table also lists a drop tank. The work table is stationary. Electrodes can weigh up to 50 kg (110 lb), and rapid traverse is 5,000 mm/min (197 ipm).
On the process side the machine carries SuperSpark4 and IES (Intelligent Expert System), adaptive power and jump controls meant to stabilise the discharge and keep electrode wear down. The SuperSurface and SuperEdge generator technologies aim at a uniform finish free of pin holes or pitting. The Hyper-i control has a 24” wide HD touch screen and a Handbox with LED display and Emergency Stop button, and its Project function walks the operator through creating a program step by step.
If parts outgrow it, the EDGE3i has 450 x 300 x 320 mm (17.7 x 11.8 x 12.6 in) of travel and a 600 x 450 mm (23.6 in x 17.7 in) table.

Strengths & Limitations
Strengths
- Flame Sensor and Fire Suppression system is standard, as is a dielectric chiller unit, which suits unattended running
- Tool changer integrated underneath the X and Y axes rather than in the work zone
- 500 kg (1,100 lb) workpiece rating on a compact 500 x 350 mm (19.7 in x 13.8 in) table
- 4-sided programmable rise-and-fall work tank plus a drop tank for access
- SuperSpark4 and IES adaptive power and jump controls aimed at a stable process and low electrode wear
Limitations
- Standard generator is 40A; the 80A generator is an option
- Travels of 300 x 250 x 250 mm (11.8 x 9.8 x 9.8 in) limit it to small inserts and electrodes
- Electrodes are limited to 50 kg (110 lb)
- Parts wider than the 300 mm (11.8 in) X travel need the EDGE3i, which has 450 mm (17.7 in)

Frequently Asked Questions
01
40A as standard, with an 80A option. The SuperSurface and SuperEdge generator technologies aim at a uniform finish free from pin holes or pitting, and SuperSpark4 with IES adapts power and jump control to keep the process stable and electrode wear low.
02
Makino configures it for unattended operation. An integrated Flame Sensor and Fire Suppression system is standard, a dielectric chiller unit is standard on the EDGEi-Series, and the automatic tool changer sits under the X and Y axes, out of the work zone.
03
Size. The EDGE2i has 300 x 250 x 250 mm (11.8 x 9.8 x 9.8 in) of travel and a 500 x 350 mm (19.7 in x 13.8 in) table. The EDGE3i has 450 x 300 x 320 mm (17.7 x 11.8 x 12.6 in) of travel and a 600 x 450 mm (23.6 in x 17.7 in) table. Both list a 5,000 mm/min (197 ipm) rapid traverse.
04
650 x 450 x 300 mm (25.6 in x 17.7 in x 11.8 in). It is a 4-sided programmable rise-and-fall tank, which opens the work zone on every side for loading, and the table also lists a drop tank. The work table itself is stationary.
05
Workpieces up to 500 kg (1,100 lb) and electrodes up to 50 kg (110 lb). The table is 500 x 350 mm (19.7 in x 13.8 in), so check the fixture footprint as well as the weight.
