How much does the Oscar EDM EX 750 cost?
Price estimate
We do not have a price for the Oscar EDM EX 750 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 Oscar EDM EX 750 is a mid-size die-sinker EDM: 700 mm (27.6 in) of X travel, 500 mm (19.7 in) in both Y and Z, and a 1000 x 600 mm (39.4 x 23.6 in) table rated for workpieces up to 3,000 kg (6,614 lb). It pairs that envelope with a 60 A maximum working current, and the combination says a lot about the work it is meant for.
A 3,000 kg block burned at no more than 60 A is a mould base or die shoe with moderate-sized cavities in it, not a part that needs a huge electrode face roughed at high current. The travels let the head reach features spread across a big block, and the 250 kg (551 lb) electrode limit allows long or ganged electrodes, but removal rate on any single burn is bounded by the current. Shops that mostly rough large-area cavities should weigh that before the table size.
Vertical room is generous. Z travel is 500 mm and the chuck-to-table distance runs 80 - 580 mm (3.1 - 22.8 in), so the chuck comes down to 80 mm above the table and a short electrode can still reach a thin plate without risers. The dielectric fills to 355 mm (14.0 in), which is the practical ceiling for a submerged burn. Maximum workpiece dimensions are 1370 x 850 mm (53.9 x 33.5 in), larger than the table in both directions.
The fluid system matches the size of the machine: 1,090 L of dielectric and 6 filter elements at 20 μm. Power consumption is 10 kVA. For rigging, the machine is 4,500 kg (9,921 lb) and the generator is listed separately at 350 kg (772 lb). The control is a Windows 10 system on an industrial i3 (or above) 64-bit CPU, with up to 6 axes (XYZCUV) when a rotary table is fitted.

Strengths & Limitations
Strengths
- 3,000 kg (6,614 lb) workpiece capacity on a 1000 x 600 mm (39.4 x 23.6 in) table
- Chuck-to-table distance starts at 80 mm (3.1 in), so short electrodes reach low workpieces without risers
- 500 mm (19.7 in) of Z travel and a 355 mm (14.0 in) dielectric fill height for deep ribs and tall blocks
- Electrodes up to 250 kg (551 lb), enough for long or ganged electrodes
- 1,090 L dielectric tank filtered by 6 elements at 20 μm
Limitations
- Maximum working current is 60 A, modest for a machine that takes 3,000 kg (6,614 lb) blocks; large-area roughing will be slow
- X travel of 700 mm (27.6 in) is about half the 1370 mm (53.9 in) maximum workpiece length, so the longest parts need a second setup
- At 4,500 kg (9,921 lb) plus a 350 kg (772 lb) generator, it needs proper rigging and a checked floor
- 6-axis operation (XYZCUV) is quoted with a rotary table, which the listing does not describe as standard

Frequently Asked Questions
01
It depends on electrode area, not on block size. The EX 750 holds workpieces up to 3,000 kg (6,614 lb) but its maximum working current is 60 A, so it is suited to heavy blocks carrying small and medium cavities. If most of your burns use large electrode faces that need high-current roughing, 60 A will make those cycles long.
02
The chuck-to-table distance is 80 - 580 mm (3.1 - 22.8 in), matching the 500 mm (19.7 in) Z travel. Workpiece, electrode and holder together must fit within 580 mm. The dielectric fills to a maximum of 355 mm (14.0 in), so the area being burned needs to sit below that level.
03
Between the EX 430 and the EX 1060 on table size and weight. The EX 430 has a 650 x 350 mm (25.6 x 13.8 in) table and weighs 1,200 kg (2,646 lb). The EX 1060 has a 1250 x 750 mm (49.2 x 29.5 in) table and weighs 5,500 kg (12,125 lb). The EX 750 is 1000 x 600 mm (39.4 x 23.6 in) and 4,500 kg (9,921 lb).
04
The dielectric tank holds 1,090 L and uses 6 filter elements rated at 20 μm. Power consumption is listed at 10 kVA. Allow for the first fill of dielectric at commissioning, and hold a set of six replacement filters so a filter change does not stop the machine.
05
A Windows 10 control on an industrial i3 (or above) 64-bit CPU. Oscar EDM lists up to 6 axes (XYZCUV) with a rotary table, on top of the 700 mm (27.6 in) X, 500 mm (19.7 in) Y and 500 mm (19.7 in) Z travels. Confirm on the quotation which axes are included.
