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

Overview

The Makino U32j is a compact precision wire EDM with 370 x 270 x 220 mm (14.6 x 10.6 x 8.7 in) of X, Y and Z travel, a 780 x 590 mm (30.7 x 23.2 in) table and a 790 x 610 mm (31.1 x 24.0 in) work tank. Makino places it above its standard U3 and U3 H.E.A.T. models for precision and surface finish, and aims it at plastic injection moulds, precision stamping tools and medical components.

The precision case rests on figures from Makino's introduction rather than the spec table: axis accuracies of 3 µm (0.0001 in) straightness and 4 µm (0.00015 in) squareness and parallelism, reached through tighter alignment specifications at assembly. Makino also quotes surface finishes down to 0.07 µm Ra with its Crystal II Circuit. Treat that as the best the machine can reach, and ask for sample cuts in your own material if finish is the reason you are buying.

The build is aimed at thermal stability. The work table is stationary, so the weight shift of a travelling table is gone, the dielectric reservoir sits inside the base casting, and chilled air circulates inside the covers around the U, V and Z axes. The tank is a programmable rise and fall design open on 3 sides, which eases manual loading and is why Makino calls the machine automation ready.

Standard wire sizes are .08, .1, .15, .2, .25 and .3 mm, and the machine can optionally run wire down to 50 µm (0.002 in) for very small internal corners. H.E.A.T. technology for poor-flush cuts is an option, as is a 3D probe for setup. The Hyper i control, its 24” class HD touch screen and the full-function Handbox are standard. If the same finish is needed on wider plates, the U53j keeps the 220 mm Z and extends travel to 550 x 370 mm (21.6 x 14.6 in).

Strengths & Limitations

Strengths

Makino states axis accuracies of 3 µm (0.0001 in) straightness and 4 µm (0.00015 in) squareness and parallelism
Surface finish down to 0.07 µm Ra with the Crystal II Circuit
Stationary work table and a dielectric reservoir in the base casting, with chilled air around the U, V and Z axes
Programmable 3-sided rise and fall tank for loading, setup and automation
Optional fine wire down to 50 µm (0.002 in) on top of the standard .08 to .3 mm range

Limitations

220 mm (8.7 in) of Z limits the height of parts that can be cut through
H.E.A.T. for poor-flush work and the 3D probe are options, not standard
X and Y travel of 370 x 270 mm (14.6 x 10.6 in) limits plate size; wider work needs the U53j with 550 x 370 mm (21.6 x 14.6 in)
Wire finer than .08 mm needs the optional fine-wire capability

Best For

Plastic injection mould inserts and cores Precision stamping punches and die sections Medical components that need a fine finish Small internal radii with optional 50 µm (0.002 in) wire

Frequently Asked Questions

01 How does the U32j differ from the U53j?

Travel and table size. The U32j has 370 x 270 x 220 mm (14.6 x 10.6 x 8.7 in) of travel and a 780 x 590 mm (30.7 x 23.2 in) table. The U53j has 550 x 370 x 220 mm (21.6 x 14.6 x 8.7 in) and an 810 x 560 mm (31.9 x 22.0 in) table. Makino describes the two as offering the same precision and finish capability, so the choice comes down to part size.

02 What surface finish can the U32j reach?

Makino quotes finishes down to 0.07 µm Ra with the Crystal II Circuit. That is a best-case figure for the finishing passes; how long it takes depends on part height, material and the number of skim cuts, so ask for a sample in your own material before relying on it for quotes.

03 What wire sizes does the U32j use?

The spec table lists .08, .1, .15, .2, .25 and .3 mm wire. Makino adds that the machine can optionally run wire down to 50 µm (0.002 in), which allows tighter internal radii on fine details. The larger sizes are the usual choice for roughing thicker sections.

04 Is the U32j ready for automation?

Makino calls the configuration automation ready. The programmable rise and fall work tank opens on 3 sides, which gives a robot or an operator clear access for loading, and an optional 3D probe can shorten setup. The robot, pallet system and part handling are not part of the listed specification.

05 Which features are optional on the U32j?

Makino lists H.E.A.T. technology, which raises productivity on poor-flush cuts, and a 3D probe system as options, along with operation on wire down to 50 µm (0.002 in). The Hyper i control with its 24” class HD touch screen, the full-function Handbox, onboard manuals, training videos and E-Tech Doctor help are standard.
