Oscar EDM NX 550

Q: How much does the Oscar EDM NX 550 cost?

The price estimate for the Oscar EDM NX 550 is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/oscar-edm-nx-550#price; the request is passed to Oscar EDM or an authorised dealer.

Overview

The Oscar EDM NX 550 is a small-to-medium die-sinker EDM with 500 x 400 mm (19.7 x 15.7 in) of X-Y travel, 350 mm (13.8 in) of Z-axis servo travel and an 800 x 450 mm (31.5 x 17.7 in) table. It is run from a 21.5 in multi-touch screen on a movable controller, backed by a color touch-screen remote control box.

In table size it sits between two EX machines. 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 750 has 1000 x 600 mm (39.4 x 23.6 in) and 4,500 kg (9,921 lb). At 1,950 kg (4,299 lb) the NX 550 stays much closer to the small machine in mass while offering a noticeably bigger table. All three name the same Windows 10 control on an industrial i3 (or above) 64-bit CPU.

Load figures are high for the footprint. Workpieces may weigh 1,350 kg (2,976 lb) and measure 1100 x 630 mm (43.3 x 24.8 in), and the head takes electrodes of 220 kg (485 lb). The generator is the limiting figure: maximum working current is 60 A on 6 kVA of power consumption, which favours detailed cavities and moderate electrode areas over heavy roughing.

Two vertical figures deserve a question to the supplier. Dielectric fills to 260 mm (10.2 in). The chuck-to-table distance is listed as 100 - 600 mm (3.9 - 23.6 in), a wider span than the 350 mm of servo travel, so ask how the rest of that range is set before planning tall setups.

The dielectric tank holds 520 L with 3 filter elements rated at 20 μm, and the generator weighs 320 kg (705 lb).

Strengths & Limitations

Strengths

21.5 in multi-touch screen on a movable controller, plus a color touch-screen remote control box
800 x 450 mm (31.5 x 17.7 in) table on a 1,950 kg (4,299 lb) machine
Workpieces up to 1,350 kg (2,976 lb) and 1100 x 630 mm (43.3 x 24.8 in)
Electrode weight limit of 220 kg (485 lb)
Chuck-to-table distance listed up to 600 mm (23.6 in)

Limitations

60 A maximum working current restricts roughing rate on large electrode faces
Z-axis servo travel is 350 mm (13.8 in), less than the 100 - 600 mm (3.9 - 23.6 in) chuck-to-table range implies
Dielectric fill height is limited to 260 mm (10.2 in)
The listing gives no axis count beyond the X, Y and Z travels

Best For

Mould inserts and electrodes of moderate area within the 60 A working current Work spread over 500 x 400 mm (19.7 x 15.7 in) of X-Y travel Operators who want a 21.5 in touch screen and a hand-held remote on a compact machine Dense blocks up to 1,350 kg (2,976 lb) on a small footprint

Frequently Asked Questions

01 How is the NX 550 operated?

From a 21.5 in multi-touch screen on a movable controller and a color touch-screen remote control box. The control runs Windows 10 on an industrial i3 (or above) 64-bit CPU. On an 800 x 450 mm (31.5 x 17.7 in) table machine the remote box is mainly a convenience for touching off and checking electrodes at the tank.

02 What is the difference between the NX 550 and the ZX 550?

The headline mechanical figures are the same: the ZX 550 also has an 800 x 450 mm (31.5 x 17.7 in) table and a 1,950 kg (4,299 lb) machine weight. The NX 550 listing names a Windows 10 control with a 21.5 in multi-touch screen and a color touch-screen remote control box. Ask Oscar EDM for the ZX 550 control details to compare the two.

03 How deep can the NX 550 burn?

The Z-axis servo travel is 350 mm (13.8 in), which is the most the electrode can feed in one stroke. The chuck-to-table distance is listed as 100 - 600 mm (3.9 - 23.6 in) and the dielectric fills to 260 mm (10.2 in), so the top of the cavity has to sit below that fluid level.

04 What workpiece and electrode weights does the NX 550 allow?

Workpieces up to 1,350 kg (2,976 lb) and electrodes up to 220 kg (485 lb). The maximum workpiece size is 1100 x 630 mm (43.3 x 24.8 in), larger than the 800 x 450 mm (31.5 x 17.7 in) table. The machine weighs 1,950 kg (4,299 lb) and the generator 320 kg (705 lb).

05 What power and dielectric does the NX 550 need?

Power consumption is listed at 6 kVA and maximum working current at 60 A. The dielectric tank holds 520 L and uses 3 filter elements rated at 20 μm.
