Honor Seiki VL-600CM

At the top of Honor Seiki's VL tables stands the VL-600CM: 7,000 mm (275.5 in) of swing and turning diameter, 2,600 mm (102.3 in) of turning height, a 100,000 kg (220,459 lb) workpiece limit, 24 tool positions and a live spindle listed at 50-2,250 rpm.

No other column combines the largest envelope with driven tools. The VL-600C matches the size and weight but turns only, with 16 tool positions. The VL-500CM matches the tool count and the height but stops at 6,000 mm (236.2 in) and 80,000 kg (176,367 lb).

Why put a live spindle on a machine this large? Because the alternative is a floor-type boring mill and a second setup for a hundred-tonne part. A main bearing ring or tower flange has to be turned on its faces and diameters and then drilled around its full circumference. Doing both under one ram keeps the hole circle concentric with the turned bore by construction, and it removes a lift that needs the heaviest crane in the building.

The page describes the structure in one sentence: a wide span column, box ways and the patented Solid lock tool clamping mechanism, for huge workpieces and hardened material, the wind power industry above all. A manual 8-jaw table is standard, as is the cabinet air conditioner on the CM series.

Everything else is open. Honor Seiki publishes no live spindle power or taper, no table diameter or speed, no travels and no machine weight for the VL-600CM. A dual speed gearbox for the live spindle, high-pressure coolant through the tool holder, extended Z travel and a Siemens controller are listed options.
