How much does the DMG Mori NT 4300 DCG cost?
Estimated price range
Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from DMG Mori. Configuration moves it a long way.
Overview
Bar capacity is the reason to pick the DMG MORI NT 4300 DCG over the NT 4250 DCG. It passes 90 mm (3.5 in) bar where the NT 4250 DCG passes 80 mm (3.1 in), and gives up a little length in return: the longest workpiece is 1,498 mm (59 in) against 1,542 mm (60.7 in) on the NT 4250 DCG. The rest of the table is shared, with travels of 750 mm (29.5 in) in X, 420 mm (16.5 in) in Y and 1,650 mm (65 in) in Z and a 660 mm (26 in) maximum workpiece diameter.
For a shop that feeds bar, the larger bore widens the range of parts that can run unattended from stock. For chuck work the two machines are interchangeable, and the choice can be made on the longest shaft in the order book instead.
The machine is a turn-mill center with a B-axis tool spindle. A direct drive motor (DDM) in the B-axis gives ±120° of rotation and allows simultaneous 5-axis machining, and the tool spindle is built to the Capto specification with 2-face contact. Z travel of 1,650 mm (65 in) is longer than the 1,498 mm (59 in) maximum part, which leaves room for the tool spindle to work past the end of a full-length shaft.
DMG MORI describes the frame as a Box in Box structure Driven at the Center of Gravity, with Octagonal Ram Construction (ORC) to manage heat at high feed rates. A digital tailstock comes as standard. The operation panel is movable and swivels, and a power-saving setting and reduced lubricating oil consumption are listed under energy saving.

Strengths & Limitations
Strengths
- 90 mm (3.5 in) bar capacity, against 80 mm (3.1 in) on the NT 4250 DCG
- Same 750 mm (29.5 in), 420 mm (16.5 in) and 1,650 mm (65 in) travels as the NT 4250 DCG, so nothing is lost in reach
- Direct drive motor in the B-axis with a ±120° rotation range
- Digital tailstock as standard and a movable, swivelling operation panel
- Capto tool spindle with 2-face contact for cutting performance and accuracy
Limitations
- Maximum workpiece length is 1,498 mm (59 in), shorter than the 1,542 mm (60.7 in) of the NT 4250 DCG
- Even at 90 mm (3.5 in), bar capacity covers only a small part of the 660 mm (26 in) diameter range; larger blanks are chucked
- Workpieces over 660 mm (26 in) in diameter need the NT 5400 DCG, with 1,040 mm (40.9 in) of X travel
- DMG MORI specifies a Capto tool spindle, so tool holders must be bought to that interface

Frequently Asked Questions
01
Choose on bar size and part length. The NT 4300 DCG takes 90 mm (3.5 in) bar and workpieces up to 1,498 mm (59 in) long. The NT 4250 DCG takes 80 mm (3.1 in) bar and workpieces up to 1,542 mm (60.7 in). Travels and the 660 mm (26 in) maximum diameter are identical.
02
750 mm (29.5 in) in X, 420 mm (16.5 in) in Y and 1,650 mm (65 in) in Z. The B-axis rotates ±120° and is driven by a direct drive motor, which DMG MORI lists as the basis for simultaneous 5-axis machining.
03
Capto. DMG MORI specifies a tool spindle with 2-face contact Capto and credits it with higher cutting performance and machining accuracy. Its Highlights give no Capto size, spindle speed or power, so ask for those with the quotation.
04
Yes, a digital tailstock is equipped as standard. DMG MORI lists it under ease of operation along with the movable, swivelling operation panel, and it serves shaft work up to the 1,498 mm (59 in) maximum workpiece length.
