Charlotte, North Carolina – The twin-spindle series DZ 22, with spindle clearance of 600mm, is designed to completely and rapidly machine complex, large workpieces, including housings for electric motors and transmissions, oil pumps, and chassis components. The company also offers a 4-axis variant of the Series 22.

Featuring two workpiece-changing table variants, the 4-axis trunnion plate version handles 680mm x 1,330mm dia., up to 600kg; and the twin-spindle 5-axis version handles 2 x 599mm x 340mm dia., up to 150kg.

Key to success of the small-footprint innovative machine concept is a machine platform using a moving gantry design. The rigid machine bed and active component cooling enable the required degree of precision on the workpiece. High acceleration – X-Y-Z max. 10-10-17m/s² – in all axes and rapid response to programming inputs ensure dynamic machining. Axis travel distances are X-Y-Z max. 620-650-600mm and rapid traverse speeds X-Y-Z max. up to 120-120-90m/min.

The magazines offer space for up to 77 tools and the integrated workpiece changer loads and unloads workpieces during machining, saving cycle time. Tool change time from 3.1 sec., chip-to-chip.

Depending on the processing task, two different main spindles are used in Series 22: a fast spindle with a speed of up to 20,000rpm and a torque of up to 137N•m for workpieces made of aluminum or aluminum alloys. Or a strong spindle with a speed of up to 12,500rpm and a maximum torque of 200N•m for hard materials and large tools. The 22 series is also available as an HSK-A100 machine for further stability and performance.

The machines are operated via the Chiron TouchLine operating system.

Series 22 is available with a ball screw drive or a linear direct drive in two plate variants: A suspension plate for 4-axis machining or two face plates for 5-axis simultaneous machining. All models can also be equipped according to the application with a cooling system, suction unit, chip conveyor, and individual tool packages.

Series 22 is prepared for the integration of various SmartLine modules to optimize productivity, product quality, and machine availability.
