How much does the DMG Mori CTX 450 cost?

Price estimate

Uncertain

We do not have a price for the DMG Mori CTX 450 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 450 is a universal turning center for workpieces up to 480 mm (18.9 in) in diameter and 800 mm (31.5 in) long. X travel is 310 mm (12.2 in) and Z travel 825 mm (32.5 in). The Y-axis has 130 mm (5.1 in) of travel, given by DMG MORI as a ±65 mm stroke, so a flat or a row of holes can sit up to 65 mm either side of centre.

The main spindle described in the Highlights is the ISM80: an integrated spindle on an A2-8 nose with a hollow cylinder of Ø 80 mm, a drive rating of 25 / 32 kW (100 / 40% duty cycle) and 4,000 rpm. The technical-data table, however, states a bar capacity of 102 mm (4 in). A 102 mm bar does not pass an Ø 80 mm bore, so anyone buying for large bar should ask which spindle the bar figure belongs to before ordering.

For work on the second side DMG MORI describes a counter spindle built as an ISM 65 integrated spindle motor: partially hollow at Ø 65 mm, rated 13/14 kW, 5,500 rpm. It has roughly half the drive rating of the main spindle, which suits finishing the cut-off side more than heavy stock removal. Confirm in the quotation whether the counter spindle and the star turret are part of the configuration offered.

The High Precision Turrets are ready for 50 bar coolant pressure, have air/oil lubrication and a 100% duty cycle in milling. The DirectDrive turret drive is optional: up to 10,000 rpm with a drive rating of 10/11 kW. Direct measuring systems in the X-axis and Y-axis are standard, the C-axis is measured on the front bearings, and the spindle motors are water-cooled. An integrated shaft unloading device and an interface for Robo2Go and Matris Light prepare the machine for automation.

The CTX 550 keeps the same X and Y travels and extends Z to 1,225 mm (48.2 in). The CTX 450 4A is slightly smaller in travel, 280 mm (11 in) in X and 760 mm (29.9 in) in Z, and the CTX 350 is the smaller machine at 250 mm (9.8 in) of X, 100 mm (3.9 in) of Y and 550 mm (21.7 in) of Z.

Strengths & Limitations

Strengths

ISM80 integrated main spindle rated 25 / 32 kW with 4,000 rpm on an A2-8 nose
130 mm (5.1 in) of Y travel, a ±65 mm stroke
Optional DirectDrive turret drive with up to 10,000 rpm and a 10/11 kW drive rating
Turrets ready for 50 bar coolant pressure, with air/oil lubrication and 100% duty cycle in milling
Integrated shaft unloading device and an interface for Robo2Go and Matris Light
Direct measuring systems in the X-axis and Y-axis as standard

Limitations

The Highlights describe an Ø 80 mm hollow cylinder while the table lists 102 mm (4 in) of bar capacity; the bar size must be confirmed
The counter spindle is rated 13/14 kW, about half the 25 / 32 kW of the main spindle
The 10,000 rpm DirectDrive turret drive is an option; no speed is given for the standard turret drive
Maximum turning length is 800 mm (31.5 in); the CTX 550 goes to 1,225 mm (48.2 in) of Z travel

Best For

Chuck parts up to 480 mm (18.9 in) in diameter Shafts and bar parts up to 800 mm (31.5 in) long Turn-mill parts with features inside the ±65 mm Y stroke Milling-heavy parts with the optional 10,000 rpm DirectDrive turret drive Automated shaft production with the integrated shaft unloading device

Frequently Asked Questions

01 What main spindle does the CTX 450 have?

The Highlights describe the main spindle as an A2-8 integrated spindle, type ISM80, with a hollow cylinder of Ø 80 mm, a drive rating of 25 / 32 kW (100 / 40% duty cycle) and 4,000 rpm. The motor is water-cooled, and the C-axis is controlled by a measuring system on the front bearings.

02 What bar diameter can the CTX 450 take?

DMG MORI's table lists a bar capacity of 102 mm (4 in). The main spindle in the Highlights, the ISM80, has a hollow cylinder of Ø 80 mm, which is smaller than that. If bar capacity decides the purchase, have the spindle and its bore stated in the quotation.

03 Does the CTX 450 have a Y-axis?

Yes. Y travel is 130 mm (5.1 in), described by DMG MORI as a ±65 mm stroke. Direct measuring systems in the X-axis and Y-axis are standard. That stroke covers keyways, flats and off-centre holes on parts up to the 480 mm (18.9 in) maximum diameter, within 65 mm of the centreline.

04 What is the counter spindle on the CTX 450?

An ISM 65 integrated spindle motor, partially hollow at Ø 65 mm, with a rating of 13/14 kW and 5,500 rpm. DMG MORI presents it with a star turret for complete machining. Check the quotation to see whether both are included in the machine offered.

05 How does the CTX 450 differ from the CTX 550?

In length. Both have 310 mm (12.2 in) of X travel and 130 mm (5.1 in) of Y travel and take 480 mm (18.9 in) in diameter. The CTX 450 has 825 mm (32.5 in) of Z travel and an 800 mm (31.5 in) maximum workpiece length; the CTX 550 has 1,225 mm (48.2 in) of Z travel.
