ZPS America LLC is introducing a cam-driven 8-spindle automatic lathe with 32 or 42 mm bar capacity. Built with a sold-base casting that ensured maximum rigidity and stability, the machine is designed for continuous or series production of precision turned parts.
ZPS America supplies multispindle production technology based on a wide range of multis for precision parts manufacturing. Since May 2009, Indianapolis-based ZPS America is the sole factory-authorized North American source for full customer support, including service, machine rebuilding, applications support, parts, training, and sales for the ZPS line of cam-driven multispindle automatic lathes.
ZPS cam-driven multispindles can accomplish a wide variety of precision metalcutting operations quickly, consistently, and accurately. The new machine 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. Machines in the range are provided with different spindle speed ranges, depending on material type and size.
The ZPS machines are designed for precision, safety, and long, reliable operation. Four safety clutches prevent the slides from overloading. Spindle drum locking is accomplished by a triad of rims with spur gearing. A bar stock guide is standard, and the machine can also include automatic bar loaders and bar magazines for long, unattended operation.
Spindles are driven by SIMODRIVE Siemens variable-speed motors and the machines are controlled through a Siemens S7.
To accomplish nearly any operation, the machines can be provided 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,” said 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 multispindle users,” he pointed out.
