How much does the Seibu M35LP cost?
Price estimate
We do not have a price for the Seibu M35LP 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 M35LP is an oil-specification ultra-precision wire EDM with an axis travel range of 350 × 300 × 170 mm (13.8 × 11.8 × 6.7 in). It appears on Seibu's Japanese product page, between the MEX15 and the M25LP in the oil lineup. The English page does not list it.
It is the largest of the oil machines in that table. The M25LP has 250 × 250 × 200 mm (9.8 × 9.8 × 7.9 in) of travel and a 150 kg (331 lb) workpiece limit. The M35LP takes 350 kg (772 lb) and a workpiece up to 700 × 630 × 150 mm (27.6 × 24.8 × 5.9 in), which makes it the candidate when a job calls for an oil dielectric on a plate-sized part.
Its outline is that of the water-specification MM35UP, 1,640 × 2,060 × 1,955 mm (64.6 × 81.1 × 77.0 in) at 2,700 kg (5,952 lb), but the working figures are tighter. The MM35UP has 230 mm (9.1 in) on the third axis and ±60 × ±60 mm (±2.4 × ±2.4 in) of U-V travel. Here the third axis is 170 mm (6.7 in) and U-V travel is ±40 × ±40 mm (±1.6 × ±1.6 in). Taper cutting is listed as ±10° at a thickness of 60 mm (2.4 in), with conical cutting.
One thing is missing. The Japanese page prints no wire diameter row, so the wire range has to be confirmed with Seibu before the machine is matched to a job. Smart NC, the MPSC-20 power supply and the MF35LP-00 filtration device are listed.

Strengths & Limitations
Strengths
- Largest travel among Seibu's oil-specification models: 350 × 300 × 170 mm (13.8 × 11.8 × 6.7 in)
- 350 kg (772 lb) workpiece limit, against 150 kg (331 lb) on the M25LP
- Accepts workpieces up to 700 × 630 × 150 mm (27.6 × 24.8 × 5.9 in)
- Same 1,640 × 2,060 × 1,955 mm (64.6 × 81.1 × 77.0 in) outline and 2,700 kg (5,952 lb) weight as the MM35UP
- Dedicated MF35LP-00 filtration device with the Smart NC control and MPSC-20 power supply
Limitations
- The source table gives no wire diameter range for this model
- Third-axis travel is 170 mm (6.7 in); the water-specification MM35UP has 230 mm (9.1 in)
- U-V travel is ±40 × ±40 mm (±1.6 × ±1.6 in), and the taper rating is given only at a 60 mm (2.4 in) thickness
- Not shown on Seibu's English product page, so availability outside Japan should be confirmed

Frequently Asked Questions
01
It is Seibu's 350×300 size wire EDM in oil specification, headed as an ultra-precision machine on the maker's Japanese product page. The axis travel range is 350 × 300 × 170 mm (13.8 × 11.8 × 6.7 in) and the maximum workpiece weight is 350 kg (772 lb).
02
The water-specification MM35UP has the same outline and weight but more height and more wire tilt: 350 × 300 × 230 mm (13.8 × 11.8 × 9.1 in) of travel and ±60 × ±60 mm (±2.4 × ±2.4 in) of U-V travel. The M35LP lists 170 mm (6.7 in) on the third axis, ±40 × ±40 mm (±1.6 × ±1.6 in) of U-V travel and a workpiece height of 150 mm (5.9 in).
03
Seibu's Japanese product page, the only page that lists this model, has no wire diameter row in its tables. The range is therefore not stated here. Ask Seibu for the standard wire and the permitted range before planning work for the machine.
04
The M35LP. Its travel in plan is 350 × 300 mm and it takes 350 kg (772 lb). The M25LP has 250 × 250 × 200 mm (9.8 × 9.8 × 7.9 in) of travel and a 150 kg (331 lb) limit, though it has more travel on the third axis and weighs more, at 3,100 kg (6,834 lb).
