8-spindle CNC Production Center

February 8, 2011

ZPS America offers the new 8-spindle ZPS 867 CNC multispindle production center, which can accommodate stock diameters up to 72 mm.

Provided with a double Siemens 840 D CNC, the machine has up to 72 CNC axes and can perform nearly any metal cutting operation on precision parts, from drilling and tapping to milling, spline gear cutting, broaching, and hobbing.

With a cast-iron base and total weight of more than 20 tons, this machine is extremely rigid, the company reports.

The machine features eight independent, AC-driven, CNC horizontal spindles; eight independent compound slides (X and Z); eight independent tool carriers with eight 12,000-RPM driven tools; five backworking tools (three driven); and presettable VDI tooling for quick changeover to increase flexibility.

Each of the machine’s eight spindles is linked by a composite shaft to its own motor into the spindle drum, which employs a precise Hirth coupling. This makes it unnecessary to reverse-index the drum at the end of each 360-degree cycle. It’s also unnecessary to connect and disconnect the motors to the spindles with each indexing and cool the drum to dissipate the heat generated by the spindle motors.  The result is greater precision and reliability across high duty cycles, the company reports. Spindle indexing takes 1 second.

Optional equipment includes a CNC pickup spindle with up to five tools (three driven) for backworking, attachments for radial and axial drilling and milling operations from cut-off slide, parts handling gripper or ejection slide, parts conveyor, barstock feeding, and high-pressure tool coolant system.
