Sodick AG200L

The Sodick AG200L is a very large sinker EDM built around a 2,500 × 1,550 mm (98.4 × 61 in) table and a 3,000 × 1,800 × 1,150 mm (118.1 × 70.9 × 45.3 in) work tank. It carries workpieces up to 10,000 kg (22,046 lb) and electrodes up to 100 kg (220 lb), and the machine itself weighs 19,000 kg (41,888 lb). It is the machine for moulds and dies that will not fit any smaller sinker in the range.

The next size down is the AL100G, with a 63.0 in × 39.37 in (1,600 × 1,000 mm) table, an 11,023 lb (5,000 kg) workpiece limit and a machine weight of 27,557.78 lb (12,500 kg). The AG200L doubles that workpiece rating but keeps the same 100 kg electrode limit, so the extra capacity goes into the part rather than into heavier electrodes. Both list 0.65 MPa air, 0.0001 mm step resolution and 4 controlled axes.

The fluid level adjusts from 520 mm (20.5 in) to 950 mm (37.4 in). Even the lowest setting is deep, so every job needs a large volume of dielectric; Sodick's table gives no capacity figure, so ask for it when sizing filtration and the oil supply.

The table sits 1,440 mm (56.7 in) above the floor, too high to load from the shop floor, so parts go in by crane and operators need a platform. The machine occupies 4,770 × 5,220 × 4,605 mm (187.8 × 205.5 × 181.3 in), and at 4,605 mm tall it needs crane hook height above that. Sodick's table also gives no X, Y or Z travel, so ask for the strokes before planning a large die: table size alone does not say how much of it the electrode can reach.
