Honor Seiki VL-86AT

The Honor Seiki VL-86AT puts two 533 mm (21 in) hydraulic chucks side by side in one machine. It is the largest Twin series model that keeps hydraulic 3-jaw chucks as standard, and each spindle is listed with 1,000 mm (39.4 in) of swing, 860 mm (33.9 in) of turning diameter, 810 mm (31.9 in) of turning height and a 25-1,500 rpm speed range. Tool positions are 12+12.

A part that fills this machine weighs hundreds of kilograms; the limit is 850 kg (1,874 lb). Nobody turns that over by hand. The value of the twin layout at this size is that the part travels a short, fixed path from the first chuck to the second, by hoist, manipulator or robot, and both sides are finished before it leaves the enclosure. Truck brake drums, large wheel hubs, ring gears and motor end shields are typical.

Honor Seiki describes the series as having two spindles and two turrets that can do the same operation on both sides or separate operations in order. The capacity rows are the same as those of the single-spindle VL-86A/AR, which suggests each side is a full VL-86.

Going up to the VL-100AT changes the character of the machine: its standard chuck is a manual 4-jaw and its spindle tops out at 850 rpm. For chucked production parts the VL-86AT is therefore the practical top of the range.

A manual chuck is optional on the VL-86 series, as are high and low pressure chucking, an automatic door and a workpiece probe. Spindle power, floor space, machine weight and the standard control are not on the page.
