How much does the DMG Mori CTX 750 cost?

Price estimate

Uncertain

We do not have a price for the DMG Mori CTX 750 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 750 is a large universal turning center for workpieces up to 700 mm (27.6 in) in diameter and bar up to 127 mm (5 in), built in two lengths. Type 1250 has 1,300 mm (51.2 in) of Z travel and takes parts 1,290 mm (50.8 in) long. Type 2000 has 2,050 mm (80.7 in) of Z travel and takes 2,040 mm (80.3 in). X travel is 435 mm (17.1 in), and the Y-axis has 170 mm (6.7 in) of travel as a ±85 mm stroke.

The two spindles are not equals. The left spindle runs up to 3,250 rpm and delivers up to 1,975 Nm, enough torque to rough a 700 mm (27.6 in) blank at low speed. The right spindle is an ISM 80 with 4,000 rpm and max. 360 Nm; an ISM 102 with 3,250 rpm and max. 770 Nm is optional. Even with the option the right side has well under half the torque of the left, so heavy stock removal belongs in the first clamping and the right spindle finishes the other side. DMG MORI describes this as 6-sided complete machining of workpieces up to Ø 700 x 2,040 mm.

Driven tools sit in a VDI 50 turret with 4,000 rpm and 84 Nm. Two further turrets are optional: a high speed turret with 6,000 rpm and 66 Nm, which gives up torque for speed, and a Direct Drive turret with 6,000 rpm and 86 Nm, which gives up neither.

Direct scales by Magnescale in X, Y and Z belong to the cooling and accuracy concept, positioning accuracy is stated as within 6 microns and 12 arcseconds, and the linear guides are up to 55 mm wide. GREENMODE covers energy monitoring, automatic shutdown, synchronous spindle drives, class IE3 motors and inverter technology for hydraulics and coolant, for up to 10% reduced energy consumption.

The CTX 550 is the next size down, with 310 mm (12.2 in) of X, 130 mm (5.1 in) of Y and 1,225 mm (48.2 in) of Z.

Strengths & Limitations

Strengths

Left spindle with up to 1,975 Nm at up to 3,250 rpm for heavy turning
Two lengths: Type 1250 with 1,300 mm (51.2 in) of Z travel and Type 2000 with 2,050 mm (80.7 in)
170 mm (6.7 in) of Y travel, a ±85 mm stroke
Direct scales by Magnescale in X, Y and Z, with positioning accuracy within 6 microns and 12 arcseconds
Bar machining up to Ø 127 mm
Optional Direct Drive turret with 6,000 rpm and 86 Nm

Limitations

The right spindle has max. 360 Nm as an ISM 80, or max. 770 Nm with the optional ISM 102, far below the 1,975 Nm of the left spindle
Both 6,000 rpm turrets are options; the VDI 50 turret drives tools at 4,000 rpm
The left spindle stops at 3,250 rpm, which is slow for small-diameter work
DMG MORI's Highlights give spindle speed and torque but no spindle power figure

Best For

Large chuck parts up to 700 mm (27.6 in) in diameter Shafts up to 2,040 mm (80.3 in) long on the Type 2000 Bar work up to 127 mm (5 in) Heavy roughing with up to 1,975 Nm on the left spindle Large turn-mill parts with features inside the ±85 mm Y stroke

Frequently Asked Questions

01 What lengths is the CTX 750 available in?

Two. Type 1250 has 1,300 mm (51.2 in) of Z travel and a maximum workpiece length of 1,290 mm (50.8 in). Type 2000 has 2,050 mm (80.7 in) of Z travel and a maximum workpiece length of 2,040 mm (80.3 in). Both have 435 mm (17.1 in) of X travel, 170 mm (6.7 in) of Y travel and a 700 mm (27.6 in) maximum workpiece diameter.

02 How much torque do the CTX 750 spindles have?

The left spindle has up to 1,975 Nm at up to 3,250 rpm. The right spindle is an ISM 80 with 4,000 rpm and max. 360 Nm, or optionally an ISM 102 with 3,250 rpm and max. 770 Nm. Rough on the left spindle and use the right one for the second side.

03 What turrets are offered on the CTX 750?

DMG MORI lists a VDI 50 turret with 4,000 rpm and 84 Nm for the driven tools. A high speed turret with 6,000 rpm and 66 Nm and a Direct Drive turret with 6,000 rpm and 86 Nm are both optional. The Direct Drive turret is the one that raises speed without losing torque.

04 How accurate is the CTX 750?

DMG MORI states positioning accuracy within 6 microns and 12 arcseconds. The Highlights tie that to a cooling concept with direct scales by Magnescale in X, Y and Z, and to linear guides up to 55 mm wide.

05 What does GREENMODE do on the CTX 750?

GREENMODE is DMG MORI's package for up to 10% reduced energy consumption. It covers energy monitoring and automatic shutdown, synchronous spindle drives and class IE3 motors, inverter technology for hydraulics and coolant, minimized compressed air consumption and low-friction linear guides with grease lubrication.
