How much does the Seibu MM35UP cost?
Price estimate
We do not have a price for the Seibu MM35UP that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Seibu MM35UP is a compact ultra-precision wire EDM for water-specification work, with an axis travel range of 350 × 300 × 230 mm (13.8 × 11.8 × 9.1 in) and a 350 kg (772 lb) workpiece limit. Only the MEX15, a far smaller machine with 150 × 150 × 120 mm (5.9 × 5.9 × 4.7 in) of travel, sits below it in the water range.
Short travel does not mean a small opening. The maximum workpiece is 700 × 630 × 220 mm (27.6 × 24.8 × 8.7 in), about twice the stroke in each plan direction. A mould plate with its features grouped in one area fits, even though it could never be cut from edge to edge.
Seibu rates taper cutting at ±10° for a work thickness of 220 mm (8.7 in). The U-V axes travel ±60 × ±60 mm (±2.4 × ±2.4 in), and ±45° at 40 mm (1.6 in) is an option. Wire from Φ0.05 to Φ0.3 mm can be run. Φ0.2 mm is standard.
Two neighbours are worth a look before deciding. The M35HP shares the frame, 1,640 × 2,060 × 1,955 mm (64.6 × 81.1 × 77.0 in) and 2,700 kg (5,952 lb), and differs in the table only by its Φ0.07 mm minimum wire. The M35LP is the oil-specification machine of the same outline, with less height: its travel is 350 × 300 × 170 mm (13.8 × 11.8 × 6.7 in) and its U-V travel ±40 × ±40 mm (±1.6 × ±1.6 in).
Smart NC control, the MPSC-20 power supply and the MF35-01 filtration device are listed for the model.

Strengths & Limitations
Strengths
- Ultra-precision class machine at 2,700 kg (5,952 lb) and 1,640 × 2,060 × 1,955 mm (64.6 × 81.1 × 77.0 in)
- Accepts workpieces up to 700 × 630 × 220 mm (27.6 × 24.8 × 8.7 in)
- Wire range of Φ0.05 to Φ0.3 mm
- Full ±60 × ±60 mm (±2.4 × ±2.4 in) U-V travel, more than the ±40 × ±40 mm (±1.6 × ±1.6 in) of the oil-specification M35LP
- ±10° taper rated at the full 220 mm (8.7 in) work thickness
Limitations
- Workpiece weight is capped at 350 kg (772 lb)
- Maximum work thickness is 220 mm (8.7 in); the MM50UP accepts 300 mm (11.8 in)
- Travel in plan is 350 × 300 mm, about half the permitted workpiece size
- ±45° taper at 40 mm (1.6 in) is listed as an option only

Frequently Asked Questions
01
The axis travel range is 350 × 300 × 230 mm (13.8 × 11.8 × 9.1 in). The table allows a workpiece up to 700 × 630 × 220 mm (27.6 × 24.8 × 8.7 in) and 350 kg (772 lb), so the practical limit for a part cut all round in one setup is the 350 × 300 mm stroke.
02
Seibu lists the MM35UP under its water-specification wire EDM heading. The oil-specification machine of the same 350×300 size is the M35LP, which has a shorter third axis and ±40 × ±40 mm (±1.6 × ±1.6 in) of U-V travel.
03
The listed range is Φ0.05 to Φ0.3 mm, with Φ0.2 mm as the standard wire. For finer wire Seibu's water range offers the MEX15, which is listed from Φ0.03 mm but takes only a 12 kg (26 lb) workpiece.
04
Both tables list the same travel, workpiece size, taper rating, dimensions and 2,700 kg (5,952 lb) weight. The MM35UP runs wire from Φ0.05 mm and the M35HP from Φ0.07 mm. Seibu heads the MM35UP as an ultra-precision machine and the M35HP as a precision machine.
05
The control device is listed as Smart NC, paired with the MPSC-20 power supply. The filtration device named for this size is the MF35-01. Seibu's product page does not describe the control's functions in public; that part of its site is for registered members.
