How much does the Makino UX3i 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 UX3i is the accuracy-focused member of the UX3 size class: 370 x 270 x 220 mm (14.6 x 10.6 x 8.7 in) of travel, a 600 kg (1,323 lb) workpiece limit and a 3-Sided 630 x 460 mm (24.8 x 18.11 in) table, with Makino's UXi changes aimed at thermal stability and wire control.
Temperature is handled at two levels. An internal radiator system cools the machine casting, and it works with a high-accuracy chiller that holds a constant temperature within ±0.1 °C, so the structure does not drift through a shift. The worktable is made to a higher flatness accuracy for better static accuracy, and an auto seal plate shower keeps the seal plate lubricated and clean.
The second set of changes is in the wire path. The Hyper Drive Extreme Wire Guide System tensions the wire with an AC servo motor, which gives a broader range of tension settings, and dynamic corner control is built into the cutting technology database to improve straightness, size and shape accuracy at corners. On small dies with sharp internal and external corners, corner error is often what decides whether a part passes inspection.
Threading is the third. Jet-less threading copes with interrupted or hollow parts and with extremely small start holes, the auto-threader anneals the wire to straighten it, and after a wire break the operator can rethread in the gap for some applications instead of returning to the start hole. Parts up to 770 x 590 x 220 mm Tall (30.3 x 23.2 x 8.7 in) fit the 790 mm x 611 mm (31.10 x 24.05 in) tank, with ±50 mm of U and V and wire from 0.070 mm to 0.300 mm.

Strengths & Limitations
Strengths
- Chiller holds machine temperature within ±0.1 °C, working with an internal radiator that cools the casting
- Higher flatness accuracy worktable for improved static accuracy
- AC servo wire tensioning with dynamic corner control built into the cutting database
- Jet-less threading for interrupted or hollow parts and very small start holes, plus rethreading in the gap after a break
- 600 kg (1,323 lb) workpiece limit and parts up to 220 mm (8.7 in) tall
Limitations
- X and Y travel of 370 x 270 mm (14.6 x 10.6 in) limits part footprint; the UX6i offers 650 x 450 mm (25.6 x 17.7 in)
- U and V travel of ±50 mm restricts taper angles on tall parts
- Makino quotes no accuracy or finish figures for the UX3i despite its accuracy focus

Frequently Asked Questions
01
Makino's UXi changes are about accuracy: an internal radiator cooling system for the casting, a chiller that holds temperature within ±0.1 °C, a higher flatness accuracy worktable and an auto seal plate shower. On the spec table the two are almost identical, and the UX3i table is listed at 630 x 460 mm against 630 x 450 mm on the UX3.
02
Jet-less threading lets it thread interrupted or hollow parts and extremely small start holes, and the auto-threading system anneals the wire to straighten it for consistent threading. After a wire break the operator can rethread in the gap for some applications, which shortens recovery time.
03
Makino describes it as part of the Hyper Drive Extreme Wire Guide System, which tensions the wire with an AC servo motor over a broader range of settings. The corner control is built into the cutting technology database and improves straightness, size and shape accuracy at corners.
04
