How much does the TRAK VMC12si cost?
Price estimate
We do not have a price for the TRAK VMC12si 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 VMC12si is a 40-taper vertical machining center with 50 in (1,270 mm) of X travel, 27.5 in (698 mm) of Y and 25 in (635 mm) of Z over a 51.18 x 23.62 in (1,300 x 600 mm) table. Its spindle runs from 10 to 12,000 rpm and is rated 67 hp (50.0 kW) peak and 26.8 hp (20.0 kW) continuous at 480V. The table carries 2,530 lbs (1,148 kg), and the machine itself weighs 15,400 lbs net (6,985 kg).
Y travel is longer than the table is deep, 27.5 in against 23.62 in, so the Y stroke covers the full depth of the table. X is the tighter axis: the table is 51.18 in long and X travel is 50 in. Vertically, the spindle nose sits between 3 in (76 mm) and 28 in (711 mm) above the table, and the fixture, the part and the longest tool all have to fit inside that 28 in. TRAK also gives the travel with soft limits as 50.07 x 27.70 x 25.06 in (1,272 x 704 x 637 mm).
The VMC10si and VMC7si share the 10 - 12,000 rpm speed range on smaller frames. The VMC10si has a 44.09 x 19.69 in (1,120 x 500 mm) table, a 2,024 lbs (918 kg) load limit and 41.5 hp (30.9 kW) peak, with 24 tools as standard and 30 optional. The VMC12si starts at 30 tools, with 40 optional. The TMC12 has the same 51.18 x 23.62 in table size, but a 16-tool carousel ATC, 22.5 hp (16.8 kW) peak and an 8,000 rpm standard top speed with 12,000 rpm optional.
Tooling is CAT40 as standard. BT40 is optional and requires a different ATC arm, so the holder type has to be settled before the machine is tooled up. The dual-arm changer has a 2.5 s arm change time and accepts tools up to 3.07 in (78 mm) in diameter and 18 lbs (8 kg) including the holder. Tool clamping force is 2,200 lbs (998 kg) at 90 psi. The coolant-through-spindle row lists a 3 kW / 4 HP pump at 319 psi, and coolant capacity is 78 gal (295 L).
For installation, power is 480 V three-phase at 69 A, with 432 to 528 V acceptable, and TRAK states that a 208V option is not available. The footprint is 168.25 x 126.50 in (4,274 x 3,213 mm) with the chip conveyor and coolant tank, and height reaches 119.25 in (3,029 mm) with the head fully up.

Strengths & Limitations
Strengths
- Spindle power of 67 hp (50.0 kW) peak and 26.8 hp (20.0 kW) continuous at 480V, against 41.5 hp (30.9 kW) peak and 20.1 hp (15.0 kW) continuous on the VMC10si
- 27.5 in (698 mm) of Y travel over a table 23.62 in (600 mm) deep, so the Y stroke is longer than the table depth
- Table load of 2,530 lbs (1,148 kg), compared with 2,024 lbs (918 kg) on the VMC10si and 1,518 lbs (689 kg) on the VMC7si
- 30-tool dual-arm ATC with a 2.5 s arm change time, and a 40-tool magazine as an option
- Coolant through the spindle is listed with a 3 kW / 4 HP pump at 319 psi, alongside 78 gal (295 L) of coolant capacity
- Spindle range of 10 - 12,000 rpm on a 40 taper, the same range as the smaller VMC10si
Limitations
- Runs on 480 V three-phase only (432 to 528 V acceptable, 69 A); TRAK states the 208V option is not available, so a 208 V shop cannot connect it directly
- Continuous spindle power is 26.8 hp (20.0 kW), 40% of the 67 hp (50.0 kW) peak, so long roughing cuts have to be planned around the lower figure
- BT40 is an option that requires changing the ATC arm; CAT40 is the standard holder
- Tools are limited to 3.07 in (78 mm) in diameter and 18 lbs (8 kg) including the holder, which rules out large face mills and heavy boring bars
- Needs a 168.25 x 126.50 in (4,274 x 3,213 mm) footprint with chip conveyor and coolant tank, and 119.25 in (3,029 mm) of height with the head fully up

Frequently Asked Questions
01
Travels are 50 in (1,270 mm) in X, 27.5 in (698 mm) in Y and 25 in (635 mm) in Z. With soft limits TRAK lists 50.07 x 27.70 x 25.06 in (1,272 x 704 x 637 mm). The table is 51.18 x 23.62 in (1,300 x 600 mm) and takes up to 2,530 lbs (1,148 kg). The spindle nose is 3 in (76 mm) from the table at its lowest and 28 in (711 mm) at its highest.
02
Both have a 40-taper spindle with a 10 - 12,000 rpm range. The VMC12si has the larger table, 51.18 x 23.62 in (1,300 x 600 mm) against 44.09 x 19.69 in (1,120 x 500 mm) on the VMC10si, and carries 2,530 lbs (1,148 kg) against the VMC10si's 2,024 lbs (918 kg). Spindle power is 67 hp (50.0 kW) peak and 26.8 hp (20.0 kW) continuous, where the VMC10si is rated 41.5 hp (30.9 kW) peak and 20.1 hp (15.0 kW) continuous. Tool capacity is 30 with 40 optional, against 24 with 30 optional. The VMC12si is also much heavier: 15,400 lbs net (6,985 kg) against 9,900 lbs net (4,491 kg) for the VMC10si.
03
CAT40 is standard. BT40 is optional, and TRAK notes that it requires changing the ATC arm. The dual-arm tool changer holds 30 tools, or 40 as an option, with a 2.5 s arm change time. A tool can be up to 3.07 in (78 mm) in diameter and up to 18 lbs (8 kg) including the holder. Tool clamping force is 2,200 lbs (998 kg) at 90 psi.
04
No. The listed requirement is 480 V three-phase at 69 A, with 432 to 528 V acceptable, and TRAK states that a 208V option is not available. The spindle power figures of 67 hp (50.0 kW) peak and 26.8 hp (20.0 kW) continuous are given for 480V.
05
The footprint is 168.25 x 126.50 in (4,274 x 3,213 mm), width by length, with the chip conveyor and coolant tank in place. Height is 106 in (2,692 mm) minimum and 119.25 in (3,029 mm) with the head fully up, so check ceiling and door clearance against the higher figure. The machine weighs 15,400 lbs net (6,985 kg) and 15,900 lbs shipping.
06
The table size is the same, 51.18 x 23.62 in (1,300 x 600 mm). The VMC12si has a 30-tool dual-arm ATC where the TMC12 has a 16-tool carousel ATC, and a 10 - 12,000 rpm spindle where the TMC12 runs 50 - 8,000 rpm as standard with 12,000 rpm optional. Spindle power is 67 hp (50.0 kW) peak against 22.5 hp (16.8 kW) peak on the TMC12, and table load is 2,530 lbs (1,148 kg) against 2,200 lbs (998 kg).
