Honor Seiki PL-350CM

The Honor Seiki PL-350CM is the largest machine in the PL series, with 4,000 mm (157.4 in) of swing and turning diameter, 2,000 mm (78.7 in) of turning height and a 35,000 kg (77,160 lb) workpiece limit. Like the two smaller PL models it pairs a vertical lathe with a gantry-type Y-axis mechanism for machining that Honor Seiki likens to a bridge type machining center.

In size it falls between two of the maker's Large vertical lathes. The VL-300CM turns 3,600 mm (141.7 in) and carries 30,000 kg (66,138 lb); the VL-400CM turns 4,500 mm (177.1 in) and carries 40,000 kg (88,183 lb). All three share the 2,000 mm height. What the PL-350CM has that those do not is the Y axis, and with it the ability to treat a turned part like a job on a large gantry mill.

The jump from the PL-200CM is large: nearly three times the load of that machine's 12,000 kg (26,455 lb) and a much wider table. Parts at this scale include machine tool beds and columns with turned locating bores, large ring gears with milled joints, press frames and segments of turbine housings. Each would otherwise be split between a vertical lathe and a floor-type or gantry mill.

The published table is brief. Tool positions are given as R16+L60 without explanation, and the speed row, though labelled live spindle speed, carries figures that track table size and is not repeated here. No Y travel, table diameter, spindle power or machine weight is listed.

Standard equipment includes a lubricant chiller for the spindle bearing and gear, a cabinet air conditioner, a table with manual 4-jaw chuck and a coolant bed shower system.
