How much does the Tongtai VTX-7II cost?

Price estimate

Uncertain

We do not have a price for the Tongtai VTX-7II 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 Tongtai VTX-7II is a 30-taper vertical machining center built for short cycle times on small parts. Travels are 710 mm (28.0 in) in X, 400 mm (15.7 in) in Y and 300 mm (11.8 in) in Z, over an 850 x 400 mm (33.5 x 15.7 in) table rated for 300 kg (661 lb).

The speed figures define it. Rapid traverse is 60 m/min (2,362 ipm) on all three axes, with acceleration listed at up to 1.2 G. Tool change is 1.2 s tool-to-tool, with 1.1 s given for a full-station index of the 21-tool magazine. On a part with dozens of drilled and tapped holes, where each cut lasts a second or two, those non-cutting figures decide the cycle time more than spindle power does.

The spindle runs to 12,000 rpm with a listed maximum torque of 84 Nm (62 lb-ft). Tongtai lists two spindle types. The High Torque type is given as 13/3.7 kW (17.4/5.0 hp), with 7.5/5.5 kW (10.1/7.4 hp) as an option. The High Efficiency type is given as 26/9 kW (34.9/12.1 hp), with 34/9 kW (45.6/12.1 hp) as an option. The table does not explain how the two ratings in each pair are defined, so ask which motor and duty rating a quoted machine carries.

The limits are those of the 30-taper class. Tools may weigh no more than 3 kg (7 lb), which rules out large face mills and long heavy holders, and 300 mm (11.8 in) of Z travel restricts tall fixtures. For bigger cutters and heavier parts, Tongtai's TMV-850QII has a No.40 spindle and a 950 x 600 mm (37.4 x 23.6 in) table rated for 800 kg (1,764 lb).

Controls are the Fanuc 0i-MF Plus or Mitsubishi M80VA with a 10.4 in display. The machine measures 2,100 x 2,600 x 2,700 mm (82.7 x 102.4 x 106.3 in) in width, depth and height and weighs 3,150 kg (6,944 lb).

Strengths & Limitations

Strengths

60 m/min (2,362 ipm) rapids with acceleration up to 1.2 G
Tool change in 1.2 s tool-to-tool
12,000 rpm spindle with 84 Nm (62 lb-ft) maximum torque
Two spindle types, High Torque and High Efficiency, each with an optional power rating
Compact at 2,100 x 2,600 mm (82.7 x 102.4 in) and 3,150 kg (6,944 lb)

Limitations

Maximum tool weight is 3 kg (7 lb)
Z travel is 300 mm (11.8 in), which limits tall fixtures and long tools
The magazine holds 21 tools and no larger option is listed
Table load is 300 kg (661 lb), against 800 kg (1,764 lb) on the TMV-850QII
X travel of 710 mm (28.0 in) is shorter than the 850 mm (33.5 in) table, so the table ends cannot be reached on the spindle centreline

Best For

Drilling and tapping of small parts where 1.2 s tool changes dominate the cycle Light milling in aluminium at up to 12,000 rpm High-volume parts that fit 710 x 400 x 300 mm (28.0 x 15.7 x 11.8 in) of travel Cells where a 2,100 mm (82.7 in) machine width allows machines to stand close together

Frequently Asked Questions

01 How fast is the VTX-7II?

Rapid traverse is 60 m/min (2,362 ipm) on X, Y and Z, and acceleration is listed at up to 1.2 G. Tool change is 1.2 s tool-to-tool, and a full-station index of the magazine is given as 1.1 s. Spindle speed is 12,000 rpm. The table does not list spindle acceleration time or a chip-to-chip figure.

02 What spindle power does the VTX-7II have?

It depends on the spindle type. High Torque is listed at 13/3.7 kW (17.4/5.0 hp), with a 7.5/5.5 kW (10.1/7.4 hp) option. High Efficiency is listed at 26/9 kW (34.9/12.1 hp), with a 34/9 kW (45.6/12.1 hp) option. Maximum torque is given as 84 Nm (62 lb-ft) without naming the spindle type it applies to, so confirm that for the version quoted.

03 What tools can the VTX-7II carry?

The magazine holds 21 tools on a 7/24 taper No. 30 spindle, and each tool can weigh up to 3 kg (7 lb). That covers drills, taps, end mills and small face mills. The table gives no maximum tool diameter or length, and lists no larger magazine.

04 What size part fits the VTX-7II?

The table is 850 x 400 mm (33.5 x 15.7 in) and carries 300 kg (661 lb). Travels are 710 mm (28.0 in) in X, 400 mm (15.7 in) in Y and 300 mm (11.8 in) in Z. The Z figure is the tight one: fixture height, part height and tool length all have to fit inside it.

05 How does the VTX-7II differ from the TMV-850QII?

They are different classes of machine. The VTX-7II has a No. 30 spindle at 12,000 rpm, a 21-tool magazine and a 300 kg (661 lb) table load, and weighs 3,150 kg (6,944 lb). The TMV-850QII has a No.40 spindle, a 24-tool standard magazine, a 950 x 600 mm (37.4 x 23.6 in) table rated for 800 kg (1,764 lb) and weighs 5,500 kg (12,125 lb).
