2014 MIYANO BND51SY2 CNC LATHES

Technical Description

The Miyano BND-51SY2 is a twin-spindle, Y-axis CNC turning center built by Miyano (now marketed by Citizen Machinery, Miyano's parent/OEM distributor) for complex bar and chucked-part machining. Per Citizen Machinery Europe's official technical data, the machine handles bar stock up to 51 mm (2.01 in) in diameter, with an optional package extending capacity to 65 mm. It is equipped with a back (sub) spindle and an independently driven Y-axis, letting rotary tools be mounted at any turret position. Maximum turning diameter over the main-spindle chuck is 175 mm (6.89 in), maximum turning length is 414 mm (16.30 in), and the distance between the main and sub spindles is 454 mm (17.87 in). The main spindle (SP1) takes a 250 mm (10 in) chuck and the sub spindle (SP2) a 120 mm (5 in) chuck. The machine runs on a Fanuc 18i-TB CNC control, has a floor footprint of 2,605 x 1,740 mm (102.6 x 68.5 in), and weighs approximately 4,600 kg (10,141 lb). The bed uses precision-scraped square slideways and a 30-degree slant-bed structure for rigidity. Spindle power, maximum spindle speed, and tool-station count were not published in the source.
