How much does the DMG Mori CTX 450 4A cost?

Price estimate

Uncertain

We do not have a price for the DMG Mori CTX 450 4A 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 4A is a universal turning machine with two tool carriers, two spindles and up to 36 tool positions. It takes workpieces up to 430 mm (16.9 in) in diameter and bar up to 102 mm (4 in), with travels of 280 mm (11 in) in X, 130 mm (5.1 in) in Y and 760 mm (29.9 in) in Z.

Both turrets can work on both spindles, one at a time or simultaneously, so two tools can cut the same part or each turret can serve its own spindle. The upper turret carries the 130 mm Y-axis, a stroke of ±65 mm. As a VDI 40 turret it has 12/16 tool stations with driven tools at up to 12,000 rpm or 38 Nm, and an optional VDI 30 version has 20 tool stations with the same speed and torque. The lower turret is a VDI 40 with 12 tool stations, 12,000 rpm and max. 38 Nm. Its optional VDI 30 version has 16 tool stations but only max. 11 Nm. The 36-position total therefore means both VDI 30 turrets, and on the lower one it costs most of the driven-tool torque.

The left spindle is an ISM 80 with 4,500 rpm and 280 Nm, or optionally an ISM 102 with 3,500 rpm and 620 Nm. The right spindle is an ISM 65 with 5,500 rpm and max. 171 Nm, or optionally an ISM 80 with 4,500 rpm and 280 Nm. Bar machining is listed up to Ø 102 mm, so check which left spindle that figure assumes.

DMG MORI states positioning accuracy within 6 µm and 12 arcseconds. Direct scales by Magnescale in X1, X2, Y1 and Z are optional. The integrated unloading device takes workpieces up to Ø 100 x 350 mm and 4 kg, which covers bar parts but not the larger chuck work. The machine does all this on 10.8 m² of floor.

The table gives a maximum workpiece length of 800 mm (31.5 in), while the Highlights describe 6-sided complete machining of workpieces up to Ø 430 x 700 mm; plan two-spindle jobs around the shorter figure. The CTX 450 has 310 mm (12.2 in) of X and 825 mm (32.5 in) of Z and takes 480 mm (18.9 in) in diameter.

Strengths & Limitations

Strengths

Two turrets that can work on both spindles individually or simultaneously
Up to 36 tool positions with the optional VDI 30 turrets: 20 tool stations above and 16 below
Driven tools at up to 12,000 rpm or 38 Nm on the VDI 40 upper turret, and 12,000 rpm with max. 38 Nm on the VDI 40 lower turret
Left spindle ISM 80 with 4,500 rpm and 280 Nm; an ISM 102 with 3,500 rpm and 620 Nm is optional
130 mm (5.1 in) Y-axis on the upper turret, a stroke of ±65 mm
Integrated unloading device for workpieces up to Ø 100 x 350 mm and 4 kg

Limitations

The optional 16-station VDI 30 lower turret has max. 11 Nm of driven-tool torque, against max. 38 Nm on the VDI 40 lower turret
Direct scales by Magnescale in X1, X2, Y1 and Z are optional
The right spindle as an ISM 65 has max. 171 Nm against 280 Nm on the left ISM 80; equal spindles need the optional ISM 80 on the right
The unloading device stops at Ø 100 x 350 mm and 4 kg, so heavier chuck parts need another way out of the machine
The Y-axis is listed for the upper turret only

Best For

Bar parts up to 102 mm (4 in) finished on both sides in one cycle Simultaneous cutting with two turrets to shorten cycle times Jobs that need many tools set up at once, up to 36 tool positions Chuck parts up to 430 mm (16.9 in) in diameter Small bar parts unloaded automatically, up to Ø 100 x 350 mm and 4 kg

Frequently Asked Questions

01 How many turrets and tool positions does the CTX 450 4A have?

Two tool carriers with up to 36 tool positions. The upper turret has 12/16 tool stations as a VDI 40 turret or 20 tool stations as the optional VDI 30 turret. The lower turret has 12 tool stations as a VDI 40 turret or 16 tool stations as the optional VDI 30 turret. Both turrets can work on both spindles, individually or simultaneously.

02 What spindles does the CTX 450 4A have?

Left spindle: ISM 80 with 4,500 rpm and 280 Nm, optionally ISM 102 with 3,500 rpm and 620 Nm. Right spindle: ISM 65 with 5,500 rpm and max. 171 Nm, optionally ISM 80 with 4,500 rpm and 280 Nm. With the optional ISM 80 on the right, both spindles have the same speed and torque.

03 How much torque do the driven tools have on the CTX 450 4A?

On the VDI 40 turrets, upper and lower, DMG MORI gives up to 12,000 rpm and 38 Nm. The optional VDI 30 upper turret with 20 tool stations has the same 12,000 rpm or 38 Nm. The optional VDI 30 lower turret with 16 tool stations is rated 12,000 rpm and max. 11 Nm, so heavier milling belongs on the upper turret in that configuration.

04 What is the largest workpiece for the CTX 450 4A?

The table gives a maximum workpiece diameter of 430 mm (16.9 in), a maximum workpiece length of 800 mm (31.5 in) and a bar capacity of 102 mm (4 in). For 6-sided complete machining DMG MORI's Highlights quote workpieces up to Ø 430 x 700 mm. Z travel is 760 mm (29.9 in).

05 How does the CTX 450 4A differ from the CTX 450?

The CTX 450 4A has two tool carriers and slightly less travel than the CTX 450: 280 mm (11 in) in X and 760 mm (29.9 in) in Z, against 310 mm (12.2 in) and 825 mm (32.5 in) on the CTX 450. Y travel is 130 mm (5.1 in) on both. The CTX 450 takes workpieces up to 480 mm (18.9 in) in diameter, the CTX 450 4A up to 430 mm (16.9 in).
