Estimated price range
Our best estimate for a cnc lathes / turning center in this class — not a quote from Doosan Machine Tools. Configuration moves it a long way.
Overview
The Doosan VTC 300M is a vertical turning center listed with a 22 kW (29.5 hp) spindle that runs to 2,000 RPM and produces 1,432 N·m, an A2-8 spindle nose and a 12-station VDI 40 turret of the ram type. DN Solutions, formerly Doosan Machine Tools (the name changed in 2022), does not list the VTC 300M in its current lineup, and it may be an older model.
The work envelope is where the table needs care, because it holds figures that do not sit together. The chuck appears as 300 mm (11.8 in) and also as 15 inch. Turning capacity appears as 350 mm (13.8 in) of height in one row and 690 mm of length in another, beside a maximum turning diameter of 830 mm and a table diameter of 600 mm (23.6 in). Travels are 500 mm (19.7 in) in X and 450 mm (17.7 in) in Z, which fits the 350 mm height far better than it fits 690 mm. Measure the chuck and read the manual before accepting a job against the larger numbers.
On the spindle side the rows agree. A torque of 1,432 N·m under a 2,000 RPM ceiling suits discs, hubs, flanges and rings: short, heavy parts that sit face-up in the chuck, where gravity helps seat them and loading is easier than on a horizontal lathe. Live tooling is optional, at 4,500 RPM and 3.7 kW (5 hp). That is enough for bolt-circle drilling and light milling, not for heavy slotting.
Rapid traverse is 15 m/min (591 ipm) in X and 12 m/min (472 ipm) in Z. Positioning accuracy is ±0.005 mm (±0.0002 in) and repeatability ±0.003 mm (±0.00012 in). The control is Fanuc 0i-TF with Doosan Smart Turning. The machine weighs 11,000 kg (24,251 lb) and carries 400 L (106 gal) of coolant.

Strengths & Limitations
Strengths
- 1,432 N·m of spindle torque with 22 kW (29.5 hp) for heavy facing and boring cuts
- 12-station VDI 40 turret, listed as a ram type
- Positioning accuracy of ±0.005 mm (±0.0002 in) and repeatability of ±0.003 mm (±0.00012 in)
- Vertical layout loads short, heavy parts face-up into the chuck
- 400 L (106 gal) coolant capacity
- Fanuc 0i-TF control with Doosan Smart Turning
Limitations
- The 2,000 RPM maximum limits surface speed on small diameters
- Live tooling (4,500 RPM, 3.7 kW (5 hp)) is optional, so a given machine may have none
- Chuck size is listed both as 300 mm (11.8 in) and as 15 inch, and turning capacity as 350 mm (13.8 in) of height and as 690 mm of length; confirm on the machine
- Z travel of 450 mm (17.7 in) rules out tall parts
- Not in DN Solutions' current lineup

Frequently Asked Questions
01
The table is not consistent on this. One row gives a 300 mm (11.8 in) hydraulic vertical chuck and another gives a chuck size of 15 inch. The table diameter is listed as 600 mm (23.6 in). Measure the chuck on the machine being offered before quoting work against either figure.
02
A maximum turning diameter of 830 mm is listed. Turning height is given as 350 mm (13.8 in) in one row and turning length as 690 mm in another. With 500 mm (19.7 in) of X travel and 450 mm (17.7 in) of Z, the smaller height figure is the safer one to plan with.
03
The spindle is listed at a maximum of 2,000 RPM, 22 kW (29.5 hp) and 1,432 N·m, with an A2-8 nose. That is a low-speed, high-torque combination for large-diameter facing and boring.
04
Live tooling is listed as optional, at up to 4,500 RPM and 3.7 kW (5 hp), on the 12-station VDI 40 turret. Check the turret on the individual machine, since the option may not have been ordered.
05
The control is Fanuc 0i-TF with Doosan Smart Turning. The machine weighs 11,000 kg (24,251 lb) and has a 400 L (106 gal) coolant capacity, so plan the floor loading and the coolant fill together.
