Overview
The DMG Mori NTX 2500 is the large-capacity model in the NTX turn-mill lineup, stepping up from the NTX 2000 with a bigger work envelope for shops that need to handle larger-diameter and longer workpieces. It handles parts up to 700 mm (27.6 in) diameter and 1,538 mm (60.6 in) turning length, making it suitable for large aerospace shafts, energy components, and heavy industrial parts.
The main spindle delivers 30 kW (40 hp) at 4,000 RPM with 478 Nm of torque through a 12-inch chuck. The sub-spindle provides 22 kW (30 hp) at 5,000 RPM. Bar capacity is 80 mm (3.1 in). The compactMASTER turn-mill spindle runs at 12,000 RPM with 18.5 kW (25 hp) through a Capto C6 interface, with HSK-A63 available. A 20,000 RPM option is offered for high-speed work.
The B-axis swivels through 240 degrees (plus/minus 120 degrees) via Direct Drive Motor. Axis travels are 755 mm (29.7 in) in X with extended range, 300 mm (11.8 in) in Y (plus/minus 150 mm), and 1,610 mm (63.4 in) in Z. Rapids hit 40 m/min on all main axes. The standard tool magazine holds 38 stations, expandable to 76. An optional lower turret with 10 live tool stations adds parallel processing.
The 3rd Generation brings CELOS X as standard, improved thermal displacement control, and 400V turning spindle. Control is Fanuc 31iB5 (Siemens CELOS optional on 3rd Gen). Floor space is approximately 4,380 x 3,080 mm, weight around 17,500 kg (38,581 lb). Pricing starts around $500,000 with production configs running $600,000-$750,000.

Strengths & Limitations
Strengths
- 700 mm turning diameter and 1,538 mm length handle large-diameter shaft and flange components that the NTX 2000 cannot accommodate
- 30 kW main spindle with 478 Nm torque provides significantly more cutting power than the NTX 2000 22 kW for heavy roughing in tough materials
- 755 mm X-axis travel with extended range provides exceptional flexibility for off-center and large-diameter machining operations
- 300 mm Y-axis travel (plus/minus 150 mm) matches the NTX 2000, maintaining full off-center milling capability on larger workpieces
- 38-to-76 tool magazine with 10-station lower turret option supports complex parts with parallel processing capability
- 80 mm bar capacity is a step up from the NTX 2000 65 mm, covering more production bar stock sizes
- 3rd Generation brings CELOS X, improved thermal control, and 400V turning spindle for better long-run accuracy
Limitations
- Starting at $500K, the step up from the NTX 2000 ($400K) needs to be justified by actual part size requirements
- At 17,500 kg, foundation requirements are more demanding than the NTX 2000 15,270 kg, adding to installed cost
- 4,000 RPM main spindle speed is lower than the NTX 2000 5,000 RPM, limiting high-speed small-diameter turning
- 4,380 x 3,080 mm floor space is 15-20 percent larger than the NTX 2000, requiring more shop real estate
- DMG Mori service and parts costs scale with machine size; expect higher annual maintenance budgets than the NTX 2000

Frequently Asked Questions
01
A new NTX 2500 starts around $500,000. Adding the 20,000 RPM milling spindle, lower turret, expanded 76-tool magazine, and automation pushes to $600,000-$750,000.
02
The NTX 2500 has a larger turning diameter (700 mm vs 670 mm), more powerful main spindle (30 kW vs 22 kW), larger bar capacity (80 mm vs 65 mm), more X-axis travel (755 mm vs 675 mm), and is heavier (17,500 vs 15,270 kg). Both share the same turning length and milling spindle.
03
The CTX gamma 1250 TC has a mineral-cast bed for superior vibration damping, more powerful main spindle (44 kW / 1,260 Nm vs 30 kW / 478 Nm), wider Y-axis (320 mm vs 300 mm), and runs Siemens exclusively. The NTX 2500 uses Fanuc (Siemens optional on 3rd Gen) and has longer Z-axis travel.
04
Most NTX 2500s run Fanuc 31iB5 with MAPPS. The 3rd Generation models offer Siemens-based CELOS X as an alternative.
