How much does the HNK VTC-30/40 cost?
Price estimate
We do not have a price for the HNK VTC-30/40 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
A 4,000 mm (157.5 in) swing, a 30,000 kg (66,138 lb) table and a milling spindle built for torque over speed: the HNK VTC-30/40 marks the change from mid-size to large in the VTC series. Its table is 3,000 mm (118.1 in) across.
The milling spindle drops to about 2,000 rpm and its motor rises to A.C 22/26 kW (29.5/34.9 hp), cont/30min, still on an ISO 50 taper. At the same time the ram stops being one size. HNK lists 300 x 300, 350 x 350 or 400 x 400 mm (11.8 x 11.8, 13.8 x 13.8 or 15.7 x 15.7 in), and a Z travel of 1,300/1,500/2,000/2,200/2,500 mm (51.2/59.1/78.7/86.6/98.4 in). For milling, ram section is the thing to press on, because a spindle hanging 2,000 mm below the rail on a slim ram will chatter long before the motor runs out of power.
Turning figures: about 100 rpm in two steps, A.C 60/75 kW (80.5/100.6 hp) on the table, 2,200 mm (86.6 in) of turning height and a rail that moves 250 mm (9.8 in) x 6 steps. X travel is -200 to +2,225 mm (-7.9 to +87.6 in).
The C-axis runs at 0 to 0.5 rpm with 0.001 degree indexing. Fanuc 31i-B and Siemens 840D are the listed controls.

Frequently Asked Questions
01
HNK lists 300 x 300/350 x 350/400 x 400 mm (11.8 x 11.8/13.8 x 13.8/15.7 x 15.7 in) and does not say which is standard. As a rule the larger section resists milling forces better at long extension, so state the deepest milled feature when asking for a quotation.
02
03
Table diameter 3,000 mm (118.1 in), swing and cutting diameter 4,000 mm (157.5 in), turning height 2,200 mm (86.6 in), table load 30,000 kg (66,138 lb) and a table speed up to about 100 rpm in two steps.
04
Table speed for indexing is 0 to 0.5 rpm. Indexing is in 0.001 degree increments. The low speed reflects the mass of a 3,000 mm (118.1 in) table and whatever is clamped to it.
