How much does the Makino U6 H.E.A.T. Extreme 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 U6 H.E.A.T. Extreme is a mid-to-large wire EDM with 650 x 450 x 420 mm (25.6 x 17.7 x 16.5 in) of X, Y and Z travel, a 4-Sided 910 x 710 mm (35.8 x 28.0 in) table and a 1,500 kg (3,307 lb) workpiece limit. Its distinguishing row is the wire list, which runs from 0.100 mm (0.004 in) to 0.400 mm (0.016 in); the UX6 and UX6i on the same travels list wire only up to 0.300 mm (0.012 in).
A 0.400 mm wire is a roughing choice. It is stiffer and carries more energy than finer wire, which suits thick sections where removal rate matters more than small corner radii. Makino's short introduction says the design was aimed at precision, running cost, speed and maintenance, but it gives no figures for any of them, so cutting speed and finish have to come from a quotation or a test cut.
The workpiece limit is 1000 x 800 x 400 mm Tall (39.4 x 31.5 x 15.8 in), inside a 1,070 mm x 880 mm (42.12 x 34.64 in) tank. A part can overhang the 910 x 710 mm table, and with a table open on all 4 sides it can be clamped from any edge. Part height stops just under the 420 mm (16.5 in) of Z. U and V travel of ±75 mm (±3.0 in) sets how much taper can be cut on a tall section.
Parts beyond this envelope go to the U86, which lists 800 x 600 mm (31.5 x 23.6 in) of X and Y on a 1220 x 910 mm (48 in x 35.8 in) table.

Strengths & Limitations
Strengths
- Takes wire from 0.100 mm to 0.400 mm (0.004 in to 0.016 in), heavier than the 0.300 mm (0.012 in) limit of the UX6
- 650 x 450 x 420 mm (25.6 x 17.7 x 16.5 in) of travel on a 4-Sided 910 x 710 mm table
- 1,500 kg (3,307 lb) workpiece limit and parts up to 1000 x 800 x 400 mm (39.4 x 31.5 x 15.8 in)
- U and V travel of ±75 mm (±3.0 in) for taper work on tall sections
Limitations
- Makino's page gives no taper angle, finish or accuracy figures, so those must come from a quotation or test cut
- Workpiece height is limited to 400 mm (15.8 in)
- X and Y travel of 650 x 450 mm (25.6 x 17.7 in) is shorter than the 800 x 600 mm of the U86 for long die plates

Frequently Asked Questions
01
The travels are the same, 650 x 450 x 420 mm (25.6 x 17.7 x 16.5 in), with ±75 mm (±3.0 in) on U and V. The U6 H.E.A.T. Extreme takes wire up to 0.400 mm (0.016 in) where the UX6 stops at 0.300 mm, and it has a 4-Sided table where the UX6 has a 3-Sided one of the same 910 x 710 mm size. Its listed workpiece height is 400 mm (15.8 in), against 420 mm on the UX6.
02
Makino lists 1,500 kg (3,307 lb) and a maximum workpiece of 1000 x 800 x 400 mm Tall (39.4 in x 31.5 in x 15.8 in Tall). The work tank is 1,070 mm x 880 mm (42.12 in x 34.64 in), so a part at the size limit leaves little room to the tank walls; check fixturing and clamping space.
03
0.100, 0.150, 0.200, 0.250, 0.300 and 0.400 mm (0.004, 0.006, 0.008, 0.010, 0.012 and 0.016 in). The 0.400 mm size is what sets this machine apart. The fine end is 0.100 mm, so work that needs very small internal radii belongs on a fine-wire machine.
04
Makino's introduction says engineering attention went into precision, running cost, speed and maintenance, but the page publishes no accuracy, finish or cutting-speed figures for this model. Ask for those figures, and a test cut, as part of any quotation.
