Exceptional performance and flexibility have already earned a production vertical turning centre with linear motor powered axis drives a high reputation in the automotive industry.

Exceptional performance and flexibility have already earned the CTV linear Series a high reputation in the automotive industry and similar high productivity sectors. With specific tooling these high-speed vertical turning machines from DMG can also perform auxiliary operations such as milling, drilling and tapping. This versatility has already enabled manufacturers to reduce unit cost significantly making them much more competitive.

With the addition of the new CTV400 linear to the range DMG has opened up this potential to larger diameters.

With a chuck capacity of up to 400mm this top-of-the-range machine has dual-track loading and unloading that can reduce handling time by up to 40%.

The high performance of the machine is complemented by a wear-free linear drive on the 1,620 X-axis that accelerates at 1G for rapid traverses up to 100m/min.

In common with its forerunners, the new CTV400 has an integrated spindle drive whose advantages are significantly greater output, high machining forces and no power loss when the spindle is idle.

Maximum torque is 730Nm and swing diameter, 500mm.

High precision and resolution are assured by the machine's direct measuring systems that also dispense with the need for time-consuming reference positioning.

The fast indexing servo turret - 0.21s for 30 and with 11.3kW on driven tools - greatly reduces idle times.

This is especially true for eccentric drilling and milling operations for which the turret can be equipped with optional Y-axis featuring a +/-100mm stroke.

To ensure good accessibility and maximum security during three-shift operation, the machine base is divided in two.

The compact and rigid base is of cast-meehanite and supported by a cast mineral foundation.

Unusual in a machine of this class, the design provides superior damping capability and a very high machine weight of 13,000kg.

This stability, in combination with the vertical spindle arrangement that supports optimum swarf clearance, creates the ideal conditions for dry and hard machining.

The inclusion of an optional multi-function T-slot plate in the work area greatly enhances the capability of this new heavyweight.

It allows additional tools to be installed in fixed or driven configuration for milling, grinding and boring as well as multi-spindle drill heads or linear tool mounts.

The modular design of this machine allows it to be easily adapted for specific customer needs.

A range of automation options is available to achieve the desired performance.

The machine is controlled by the Windows-based Siemens 840D controller that is of course compatible with the full DMG range of Powertools software support packages including DMG Netservice.
