How much does the Makino UPN-01 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 UPN-01 is a small ultra-precision wire EDM for fine-wire work: 160 x 160 x 50 mm of X, Y and Z travel, ±7 mm (±0.28 in) of U and V, and a workpiece limit of 150 x 150 x 40 mm (5.9 x 5.9 x 1.6 in) and 8 kg (17.6 lb). It runs wire from 0.100 mm (0.004 in) down to 15 µm (0.0006 in), and its horizontal wire drive layout can thread start holes as small as 30 µm (0.001 in).
The motion system is what separates it from a conventional wire EDM. Makino pairs pneumatic static pressure guideways with linear motors to minimise friction and inertia, and claims sub-micron accuracy from the combination. Feedback comes from a 0.01 µm (10 nm) scale, giving a minimum programmable increment of 0.1 µm (0.000004 in) and a mechanical movement roundness of 0.2 µm (0.000008 in).
The dielectric is oil, which Makino says gives greater control of the spark gap and improves part accuracy, surface finish and metallurgical quality, with finishes down to 0.02 µm Ra (1 µin Ra). The whole work zone is enclosed and temperature controlled, so long unattended runs are not upset by changes in the shop.
An integrated rotary C-axis indexes to ±2 arc seconds (±0.00056 degrees) and also exchanges workpieces automatically, and an automatic slug ejection system can be added to extend unattended running further. The control is Makino's Hyper i, shared with its sinker EDMs, on a 24” class HD touch screen. The limits are just as clear: 50 mm of Z and an 8 kg part weight make this a machine for small, thin, high-value parts and nothing else.

Strengths & Limitations
Strengths
- Wire from 0.100 mm (0.004 in) down to 15 µm (0.0006 in), with start holes as small as 30 µm (0.001 in)
- Pneumatic static pressure guideways and linear motors, with a 0.01 µm scale and a 0.1 µm (0.000004 in) minimum increment
- Oil dielectric and finishes down to 0.02 µm Ra (1 µin Ra)
- Integrated rotary C-axis indexing to ±2 arc seconds (±0.00056 degrees) with automatic workpiece exchange
- Enclosed, temperature-controlled work zone for long unattended runs
Limitations
- 50 mm of Z travel and a 40 mm (1.6 in) part height limit restrict it to thin, small parts
- Workpiece weight is limited to 8 kg (17.6 lb)
- Automatic slug ejection is additional equipment, not part of the base machine
- Running on oil means parts leave the machine oily and the shop must handle dielectric oil

Frequently Asked Questions
01
Makino gives a range from 0.100 mm (0.004 in) down to 15 µm (0.0006 in), and says the horizontal wire drive layout can reliably thread start holes as small as 30 µm (0.001 in). That makes it a machine for micro features rather than general wire EDM work.
02
The maximum workpiece is 150 mm x 150 mm x 40 mm Tall (5.9 in x 5.9 in x 1.6 in Tall) and 8 kg (17.6 lb). Travel is 160 x 160 x 50 mm, with ±7 mm (±0.28 in) of U and V. The work tank measures 275 mm × 430 mm × 330 mm (10.82 in x 16.92 in x 12.99 in).
03
Makino describes the UPN-01 as capable of sub-micron accuracy. It uses a 0.01 µm (10 nm) scale feedback system and a minimum programmable increment of 0.1 µm (0.000004 in), and quotes a mechanical movement roundness of 0.2 µm (0.000008 in), achieved with pneumatic static pressure guideways and linear motors.
04
Makino says the oil dielectric gives greater control of the spark gap, which improves part accuracy, surface finish and metallurgical quality. The quoted finish is down to 0.02 µm Ra (1 µin Ra). The work zone is also enclosed and temperature controlled to limit thermal change during long runs.
05
The integrated rotary C-axis indexes to ±2 arc seconds (±0.00056 degrees) and also handles automatic exchange of the workpiece. An automatic slug ejection system is available as additional equipment to extend unattended machining further.
