How much does the TRAK VMC7si cost?
Price estimate
We do not have a price for the TRAK VMC7si 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
The TRAK VMC7si is a 40 Taper vertical machining center with 30 x 20 x 20 in (762 x 508 x 508 mm) of travel, a 10 - 12,000 rpm spindle and a 24-tool dual-arm changer. Its table is 35.43 x 19.69 in (900 x 500 mm) and carries 1,518 lbs (689 kg).
The spindle is the centre of the specification. At 480V it is rated 41.5 hp (30.9 kW) peak and 20.1 hp (15.0 kW) continuous, and 12,000 rpm is the listed top speed with no option needed to reach it. Feeds match: rapid traverse is 1,000 ipm (25.4 m/min) and the maximum cutting feed rate is the same 1,000 ipm (25.4 m/min), so the machine can feed as fast as it positions.
Tool handling is built for longer cycles. The dual-arm changer swaps in 2.5 s and holds 24 tools, or 30 as an option. A tool may weigh 18 lbs (8 kg) with its holder and measure 3.07 in (78 mm) across. CAT40 is standard. BT40 is optional and requires a different ATC arm, so the holder standard should be settled before ordering. TRAK's table also gives a coolant-through-spindle pump of 3 kW / 4 HP at 319 psi.
A buyer comparing it with the TMC7 will find the same table and nominal travels. The TMC7 lists 15 hp (11.2 kW) peak, 8,000 rpm as standard and a 16-tool carousel, and it runs from a 208V supply. The VMC7si asks for more from the building in return for its spindle.
Specifically, it wants 480 V three-phase at 41 A, with 432–528 V acceptable. A transformer option allows 208 V at 94 A. With chip conveyor and coolant tank the footprint is 144 x 112 in (3,658 x 2,845 mm), and height is 93.5 in (2,375 mm) minimum, 108 in (2,743 mm) with the head fully up.
