Honor Seiki VL-400C

With a 4,500 mm (177.1 in) swing and turning diameter, the Honor Seiki VL-400C sits second in the Large vertical lathe range. It keeps the 2,000 mm (78.7 in) turning height and 16 tool positions of the VL-300C and raises the workpiece limit to 40,000 kg (88,183 lb).

Notice how the two rows move. Diameter grows by a quarter over the VL-300C at 3,600 mm (141.7 in), while load grows by a third over that machine's 30,000 kg (66,138 lb). The VL-400C is the same machine concept stretched for a wider ring, not a taller or radically heavier part. If the work is a larger-diameter version of what a VL-300C already does, this is the natural column. If the part is much heavier, the next step is steep: the VL-500C carries 80,000 kg (176,367 lb).

Ring-shaped parts are the stated purpose. Honor Seiki describes the range as built with a wide span column, box ways and its patented Solid lock tool clamping mechanism for huge workpieces and hardened material, with wind power named as the main application. The standard table has a manual 8-jaw chuck.

The VL-400C is a turning machine. The live spindle row is blank, and the cabinet air conditioner that comes with the CM series is an option here. An optional dual spindles model is mentioned for the range without figures.

Nothing on the page gives the table diameter, table speed, drive power, ram section or machine weight. At this size those numbers decide the foundation, the crane and the building, so the published table is a starting point for a conversation with the maker and not a full specification.
