In response to the automotive and aerospace industries demand for dynamic, precise, and highly productive complete machining processes for their larger structural parts, the Chiron Group introduced the DZ 28 twin-spindle vertical machining centers featuring 1,200 mm spindle clearance and tool magazine with space for up to 60 tools.

“With the 28 Series, we are addressing new customers and workpieces,” said Kristoffer Siegmann, head of global account management automotive at Chiron Group. “Previously, only single-spindle manufacturing could be used for components of this size, but the new DZ 28 twin-spindle machines permit considerably shorter cycle times – while delivering optimum part quality.”

There are two versions of the twin-spindle machining center available: The DZ 28 P five-axis with pallet changer for high quantities and short cycle times, and the DZ 28 S five axis for direct loading.

This new machining center series can be flexibly configured to completely machine larger-sized structural parts which require maximum surface quality and dimensional accuracy, as well as high production rates and minimal downtime. Users will benefit from the machine’s compact layout, available robot or gantry automation, and fully independent Z and X-direction spindles.

The DZ 28’s design allows Chiron’s characteristic speed and precision to be applied to more part families such as side beams, battery cases and housings for power electronics, as well as blades, blisks and impellers for engine and turbine building. 

High axis acceleration and rapid traverse ensure more dynamic machining has previously been possible with workpiece dimensions in this range. The portal construction, rigid machine bed and active component cooling enable the required degree of precision on the workpiece.

A major advantage to the 28 Series, especially with large workpieces, is that operating and loading take place on separate sides. This means the operator has clear access to the working area and an unobstructed view into the machining process. 

The DZ 28 is operated via Chiron’s TouchLine, the established operating system from the Chiron SmartLine portfolio. A large display panel allows easy monitoring of the machine condition at all times and as with all of the Chiron Group's new series, the 28 Series is prepared for integration of all SmartLine modules. For example, this includes ProtectLine for preventive protection against machine crashes and ConditionLine for automatic condition monitoring of relevant machine components.
