How much does the HNK VTC-25/30 cost?
Price estimate
We do not have a price for the HNK VTC-25/30 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
On the HNK VTC-25/30 a 20,000 kg (44,092 lb) part can be turned, milled and drilled without leaving the table. The machine has a 2,500 mm (98.4 in) table, 3,000 mm (118.1 in) of swing and cutting diameter and 2,000 mm (78.7 in) of turning height.
It is the largest VTC that still mills at about 2,500 rpm. From the VTC-30/40 up, the milling spindle is limited to about 2,000 rpm. The motor here is A.C 18.5/22 kW (24.8/29.5 hp), cont/30min, with an ISO 50 taper. It is also the largest size with a single, stated ram: 240 x 240 mm (9.4 x 9.4 in), with 1,200 mm (47.2 in) of Z travel. Above it the catalogue lists alternatives.
The C-axis slows as tables grow. Here the table speed for indexing is 0 to 1 rpm, half that of the VTC-20/25, with 0.001 degree indexing. For positioning drilled holes that hardly matters. For C-axis contour milling on a large radius it sets the feed available at the cutter, so check it against the job.
Turning speed is about 130 rpm in two steps from an A.C 45/55 kW (60.3/73.8 hp) motor. The rail moves 250 mm (9.8 in) x 4 steps and X travel is -200 to +1,700 mm (-7.9 to +66.9 in). Controls: Fanuc 31i-B, Siemens 840D.

Frequently Asked Questions
01
The table is rated for 20,000 kg (44,092 lb). Swing and cutting diameter are 3,000 mm (118.1 in) and turning height 2,000 mm (78.7 in), on a table of 2,500 mm (98.4 in).
02
0 to 1 rpm for indexing, with 0.001 degree as the indexing increment. The VTC-20/25 lists 0 to 2 rpm and the VTC-30/40 lists 0 to 0.5 rpm, so the figure falls steadily with table size.
03
A 240 x 240 mm (9.4 x 9.4 in) ram with 1,200 mm (47.2 in) of vertical travel and a 40 x 40 mm (1.6 x 1.6 in) shank for turning tools. The next size, the VTC-30/40, lists rams from 300 x 300 to 400 x 400 mm (11.8 x 11.8 to 15.7 x 15.7 in).
04
The VTC-25/30 runs its milling spindle to about 2,500 rpm; the VTC-30/40 stops at about 2,000 rpm but has a larger A.C 22/26 kW (29.5/34.9 hp) motor. Small drills and end mills favour the higher speed.
