New Twin Spindle VMCs from CHIRON


The latest twin spindle VMC in CHIRON America’s line-up is the DZ15WM IWW, featuring an 800mm trunnion bridge plate with a swing circle of 450mm. Other recently introduced twins include the DZ 15 KW MAGNUM IWW high speed vertical machining center with an envelope of 15.75" x 15.75" x 16.75" (400 x 400 x 425mm) in the X, Y, and Z axes as well as the CHIRON tool changer with 2 x 12 tools (SK 40/HSK 63). The twin-spindle DZ 15K W Magnum IWW has an X, Y, and Z envelope of 27.58" x 15.75" x 14.18" (700 x 400 x 360mm) and 2 x 24 HSK-A 63 tools in the chain magazine. Typical applications for twin spindle VMCs include steering systems, and engine, drive train, and chassis parts.

The standard chain magazine allows the use of as many as 48 tools (up to 60 mm diameter) in the smallest amount of space. This provides enough tools for complex processing, with immediate access. Using digital direct drives, a complete tool change cycle takes only 0.9 seconds. Within this time both spindles are stopped, both tools exchanged, and accelerated back to maximum rotation, which results in a chip-to-chip time of 2.4 seconds.

Just like the base single spindle models, the twin-spindle-machining centers are equipped with a workpiece changing table for parallel loading and off-loading, the workpiece changer is integrated into the machine base, and it is equipped with self learning speed control. The simultaneous use of two high-performance spindles automatically promises twice the productivity while saving much needed floor space.

Headquartered in Charlotte, North Carolina, CHIRON America, Inc., is a supplier of German- and American-built high speed single and twin-spindle vertical machining centers and fully automated turnkey production cells for markets in the U.S., Canada, and Mexico. The parent company is CHIRON Werke GmbH & Co. KG of Tuttlingen, Germany.
