Price estimate

Uncertain

We do not have a price for the DMG Mori CTX 2500 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 DMG MORI CTX 2500 is a universal turning center built in two lengths around a 12 station VDI turret and a choice of two main spindles. Both lengths take workpieces up to 430 mm (16.9 in) in diameter and bar up to 102 mm (4 in), with 260 mm (10.2 in) of X travel and 100 mm (3.9 in) of Y travel. Type 700 has 795 mm (31.3 in) of Z travel and a maximum workpiece length of 734 mm (28.9 in). Type 1250 has 1,345 mm (53 in) of Z travel and takes parts up to 1,284 mm (50.6 in) long.

The spindle choice is a trade between speed and torque. The standard main spindle runs to 4,000 rpm with 387.2 ft lb. The optional one is limited to 3,500 rpm and delivers 880.6 ft lb, more than twice the torque. Large-diameter roughing in steel reaches its surface speed at low rpm and runs out of torque first, so shops cutting near the 430 mm (16.9 in) limit should look at the option; bar and small chuck work is served by the standard spindle.

Three turret drives appear in DMG MORI's Highlights. The 12 station turret with VDI interface is standard and drives tools at 6,000 rpm with 13.4 hp and 26.6 ft lb. The torqueDRIVE turret keeps 6,000 rpm and is rated 31.5 hp with a maximum torque of 62.7 ft lb, which is the one for face mills and larger drills. The speedDRIVE turret is optional and reaches 12,000 rpm with 26.8 hp and a maximum of 41.3 ft lb, for small tools that need the speed.

A counter spindle with up to 5,000 rpm, 42.9 hp and 265.6 ft lb is optional, as is the star turret that goes with it, so the base machine finishes one side of the part. The guideways are 3.1 in. wide, and coolant circulates through all cast components to keep the temperature shift uniform.

The CTX 450 has more cross travel, 310 mm (12.2 in) in X and 130 mm (5.1 in) in Y, with 825 mm (32.5 in) of Z. The CTX 550 has the same X and Y as the CTX 450 and 1,225 mm (48.2 in) of Z, which is shorter than the Type 1250 here.

Strengths & Limitations

Strengths

Two lengths: Type 700 with 795 mm (31.3 in) of Z travel and Type 1250 with 1,345 mm (53 in)
Standard main spindle with 4,000 rpm and 387.2 ft lb, or an optional spindle with 3,500 rpm and 880.6 ft lb
12 station turret with VDI interface as standard, driving tools at 6,000 rpm with 13.4 hp and 26.6 ft lb
torqueDRIVE turret with 6,000 rpm, 31.5 hp and a maximum torque of 62.7 ft lb for heavier milling
Guideways 3.1 in. wide, with coolant circulation through all cast components
Bar capacity of 102 mm (4 in) on a machine that also chucks 430 mm (16.9 in) blanks

Limitations

The 880.6 ft lb main spindle is an option and is limited to 3,500 rpm; the standard spindle has 387.2 ft lb
The 12,000 rpm speedDRIVE turret is optional, and its maximum torque of 41.3 ft lb is below the 62.7 ft lb of the torqueDRIVE turret
Counter spindle and star turret are options, so second-side machining is not part of the base machine
Y travel is 100 mm (3.9 in), against 130 mm (5.1 in) on the CTX 450 and CTX 550

Best For

Chuck parts up to 430 mm (16.9 in) in diameter Shafts up to 1,284 mm (50.6 in) long on the Type 1250 Bar-fed work with stock up to 102 mm (4 in) Heavy roughing with the optional 880.6 ft lb main spindle Turn-mill parts using the 6,000 rpm driven-tool turret

Frequently Asked Questions

01 What is the difference between the CTX 2500 Type 700 and Type 1250?

Length only, as far as DMG MORI's table shows. Type 700 has 795 mm (31.3 in) of Z travel and a maximum workpiece length of 734 mm (28.9 in). Type 1250 has 1,345 mm (53 in) of Z travel and takes workpieces up to 1,284 mm (50.6 in). X travel of 260 mm (10.2 in), Y travel of 100 mm (3.9 in), the 430 mm (16.9 in) maximum diameter and the 102 mm (4 in) bar capacity are common to both.

02 Which main spindle should I choose on the CTX 2500?

The standard main spindle has 4,000 rpm and 387.2 ft lb. The optional spindle has 3,500 rpm and 880.6 ft lb. Choose the option for large diameters and heavy roughing, where torque limits the cut; keep the standard spindle for bar work and smaller parts that benefit from the higher top speed.

03 What turret options does the CTX 2500 have?

The standard turret has 12 stations with VDI interface and a 6,000 rpm drive rated 13.4 hp and 26.6 ft lb. DMG MORI also lists a torqueDRIVE turret with 6,000 rpm, 31.5 hp and a maximum torque of 62.7 ft lb, and an optional speedDRIVE turret with 12,000 rpm, 26.8 hp and a maximum of 41.3 ft lb.

04 Can the CTX 2500 machine both sides of a part?

Only with the optional counter spindle, which DMG MORI rates at up to 5,000 rpm, 42.9 hp and 265.6 ft lb. A star turret is listed as an option alongside it for complete machining. Without them the part has to be turned around by hand or in a second operation.

05 How does the CTX 2500 compare with the CTX 450?

The CTX 450 has 310 mm (12.2 in) of X travel, 130 mm (5.1 in) of Y and 825 mm (32.5 in) of Z, and takes workpieces up to 480 mm (18.9 in) in diameter. The CTX 2500 has 260 mm (10.2 in) of X and 100 mm (3.9 in) of Y, but its Type 1250 reaches 1,345 mm (53 in) of Z, which the CTX 450 does not offer.
