Honor Seiki VL-100A/AR

The Honor Seiki VL-100A/AR tops the High Speed Series and behaves differently from the three sizes under it. Its chuck is listed at 1,000 mm (40 in), nearly double the 533 mm (21 in) of the VL-86A/AR, and the spindle range drops to 5-850 rpm. Swing is 1,320 mm (52 in), turning diameter 1,100 mm (43.3 in) and turning height 920 mm (36.2 in).

The standard workholding changes too. Every smaller model in the series ships with a hydraulic 3-jaw chuck; the VL-100 comes with a manual 4-jaw chuck, and the hydraulic chuck with rotary cylinder moves to the option list. A 4-jaw lets the operator dial in castings, fabrications and rings that are not round enough for self-centring jaws. It is slower to load, so a shop planning repeat production should cost in the hydraulic option from the start.

One figure has not grown in step with the chuck. Maximum workpiece weight is 1,000 kg (2,205 lb), only a little above the 850 kg (1,874 lb) of the VL-86A/AR. A solid steel disc that fills a 1,100 mm turning diameter reaches that limit at modest thickness, so this is a machine for large, relatively light parts: rings, thin flanges, covers, wheel-type castings. Honor Seiki's Heavy Duty Series covers the same diameters with far higher load ratings, for instance 3,500 kg (7,716 lb) on the VL-100C.

The turret has 12 tool positions with coolant through the turret as standard. The low end of 5 rpm suits large-diameter facing at controlled surface speed. Spindle power, torque, travels and the standard control are not printed on the page.
