ZPS America LLC is introducing a cam-driven, 8-spindle automatic lathe with 32- or 42-mm bar capacity that’s designed for continuous or series production of precision turned parts. The machine is designed and built in Europe with a solid base casting that ensures maximum rigidity and stability during operation. The builders ensure that all ZPS machines are “designed for precision, safety, and long, reliable operation.”
The ZPS 832 includes eight frontal slides with up to 110 working strokes, and eight cross slides plus four compound slides with clamping, and bar stop in the eighth station. An independent cam controls each slide. Stroke is adjustable on the rocker arm of the corresponding drive. ZPS will customize the machine for different spindle speed ranges, depending on material type and size.
Four safety clutches prevent the slides from overloading, and three rims with spur gearing achieve spindle-drum locking. A bar stock guide is standard, and the machine can also include automatic bar loaders and bar magazines for long, unattended operation.
The machine’s eight spindles are driven by Siemens’ SIMODRIVE variable speed motors and the machines are controlled through a Siemens S7 automation package.
ZPS will outfit the machines with a range of optional equipment, including NC drive of the pick-up spindle, bar stock feeding and clamping in the fourth station, attachments for high-speed drilling, reaming, tapping and broaching, and multi-spindle drilling heads on the frontal slides.
“Because ZPS America is the factory, we can help you upgrade your cam machines with CNC slides and Siemens controls, and even help evaluate whether to exchange your ZPS cam machine for one of our CNC multis,” stated Olaf Tessarzyk, managing partner and president of ZPS America. “To help customers maintain trouble-free performance, we also offer full preventative maintenance plans for each of our machines. Prompt factory service from local resident service and applications engineers and spare parts are very important to multi-spindle users,” he pointed out.
