How much does the Makino U3 Wire EDM cost?
Estimated price range
Our best estimate for a wire edm in this class — not a quote from Makino. Configuration moves it a long way.
Overview
The Makino U3 Wire EDM on this page is a small wire EDM with listed travels of 350 x 250 x 220 mm and a listed workpiece limit of 500 kg. The U3 is not in Makino's current lineup, and the table could not be checked against a Makino source, so read every figure here as the listed figure for an older, used machine rather than a confirmed specification.
That envelope suits die inserts, punches and small plates. The 220 mm of Z sets the tallest part that can be cut through, and 500 kg is more than a steel block that fits within 350 mm of X is likely to weigh. The listed wire range is 0.1 – 0.3 mm, with a taper figure of ±30° / 100 mm and a Makino Hyper-i control. The nearest current machine is the U32j, which lists 370 x 270 x 220 mm of travel: slightly more on X and Y, the same Z.
On a used U3, ask for the control version, the installed options and a test cut in your own material. The listed cutting speed of 380 mm²/min and the Ra 0.1 µm finish are best-case numbers that depend on wire, material and part height. The listed machine weight is ~3,800 kg, so check floor loading and rigging before you commit.

Strengths & Limitations
Strengths
- Listed travels of 350 x 250 x 220 mm and a 500 kg workpiece limit cover typical die inserts and punches
- Listed wire range of 0.1 – 0.3 mm runs from fine detail wire to general cutting wire
- Listed taper figure of ±30° / 100 mm for die clearance and draft work
Limitations
- Not in Makino's current lineup, and the listed figures could not be checked against a Makino source
- The 220 mm Z travel caps the height of parts that can be cut through
- At a listed ~3,800 kg, the machine needs a floor and rigging plan before delivery

Frequently Asked Questions
01
It is not in Makino's current lineup, so a U3 today is a used machine. The figures on this page are the listed ones and could not be checked against a Makino source. The nearest current model is the U32j, which lists 370 x 270 x 220 mm of travel and a 780 x 590 mm (30.7 x 23.2 in) table.
02
The listed travels are 350 x 250 x 220 mm and the listed workpiece limit is 500 kg. Height is set by the 220 mm of Z. The table on this page gives no table or tank size, so measure the actual machine before quoting a large plate on it.
