How much does the Makino U6i 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 U6i on this page is a mid-size wire EDM with listed travels of ~600 x ~400 x ~310 mm (23.6 x 15.7 x 12.2 in), a table of ~900 x 600 mm (35.4 x 23.6 in) and a workpiece limit of ~700 kg (1,543 lb). It is not in Makino's current lineup, the table could not be matched to a Makino source, and several of its rows are marked as approximate. Read every figure here as a starting point for inspecting a used machine, not as a specification.
The taper axes are listed at ±80 mm (±3.1 in) on U and V with a taper angle of +/-30 degrees, and the wire range at 0.05 - 0.30 mm (0.002 - 0.012 in). The fine end of that range is what small internal radii need; the heavy end is for thick sections. The table also names a Makino Hyper-i touchscreen control and an adaptive AC discharge generator, without a version for either, so confirm both on the machine.
The tightest rows are the ones to verify. The table lists positioning accuracy of +/-0.001 mm (+/-0.00004 in) and a surface finish of 0.05 um Ra (2 uin Ra). Neither could be checked against a Makino source, so ask for the machine's accuracy records and a test cut in your own material before relying on them.
For scale, the current UX6i lists 650 x 450 x 420 mm (25.6 x 17.7 x 16.5 in) of travel and a 4-Sided 910 x 710 mm table, so it is larger on every axis. The listed machine weight of ~5,000 kg (11,023 lb) sets the floor and rigging requirement.

Strengths & Limitations
Strengths
- Listed ~600 x ~400 mm (23.6 x 15.7 in) of X and Y travel on a ~900 x 600 mm (35.4 x 23.6 in) table
- Listed U and V travel of ±80 mm (±3.1 in) with a taper angle of +/-30 degrees
- Listed wire range of 0.05 - 0.30 mm (0.002 - 0.012 in) covers fine detail as well as general cutting
- Listed Z travel of ~310 mm (12.2 in) for moderately tall die blocks and mould plates
Limitations
- Not in Makino's current lineup, and the listed figures could not be checked against a Makino source
- The travels, table, part weight and machine weight are all given only as approximate values
- The listed ~700 kg (1,543 lb) workpiece limit is below the 1,500 kg (3,307 lb) of the current UX6i
- Listed machine weight of ~5,000 kg (11,023 lb) needs a floor and rigging plan

Frequently Asked Questions
01
No. The U6i is not in Makino's current lineup, and this page's table could not be matched to a Makino source. Anyone buying one is buying a used machine, so the travels, accuracy and finish rows should be checked on the machine itself rather than taken from this page.
02
The listed travels are ~600 x ~400 x ~310 mm (23.6 x 15.7 x 12.2 in) on a table of ~900 x 600 mm (35.4 x 23.6 in), with a listed workpiece limit of ~700 kg (1,543 lb). Measure the actual tank and Z stroke before quoting a part near those limits.
03
The current UX6i lists 650 x 450 x 420 mm (25.6 x 17.7 x 16.5 in) of travel, a 4-Sided 910 x 710 mm table and a 1,500 kg (3,307 lb) workpiece limit. On the listed figures the U6i is smaller on every axis and carries less weight, so it is not simply an older name for the same machine.
04
Positioning accuracy of +/-0.001 mm (+/-0.00004 in) and a surface finish of 0.05 um Ra (2 uin Ra). Both are unverified and tighter than a buyer should assume without proof, so ask for the machine's latest accuracy check and cut a sample in your own material.
