Danobat IED-500

Two turrets working at once define the Danobat IED-500. Where the ID models of the Overbeck ID/IED series grind a bore and then an outside diameter, the IED brings what Danobat calls a dual-turret design for simultaneous ID and OD grinding, and credits it with cutting cycle times by up to 50%. It is the production variant of the family.

The second slide shows in the spec table as its own pair of axes. X and Z travel 220 mm (8.66 in) and 550 mm (21.65 in); X2 and Z2 travel 320 mm (12.60 in) and 450 mm (17.72 in). No other machine in the series lists X2 and Z2 strokes.

Capacity is balanced between inside and outside. Bores up to 300 mm (11.81 in) are ground to a length of 150 mm (5.91 in), and outside diameters up to 300 mm (11.81 in) to a length of 250 mm (9.84 in). Swing is 300 mm (11.81 in) and the part with its clamping can be 250 mm (9.84 in) long, so the IED-500 gives up the 560 mm (22.05 in) swing of the ID-500 in exchange for the second wheel in the cut. Workpiece weight including clamping is listed as 80 kg (176 lb) / 100 Nm to 180 kg (397 lb) / 300 Nm.

Everything else is shared Overbeck practice: natural granite base, linear motors with active cooling, a direct-drive workhead built in-house, and grinding spindles with integrated motors. Danobat's turret description for the series is a direct driven unit with a 300° swivelling range and up to 4 spindles and one measuring probe. At 220 x 250 x 255 cm (86.61 x 98.43 x 100.39 in), height x width x depth, the machine is deeper than the ID-500 and narrower.
