CAM-DRIVEN 6-SPINDLE LATHE FOR SPEED, PRECISION, ACCURACY ON TURNED PARTS

The multispindle includes six frontal slides with up to 142 working strokes, and six cross slides plus four compound slides with clamping, and bar stop in the 6^th station.

This cam-driven 6-spindle automatic lathe from ZPS America LLC (Indianapolis, IN) has 51 to 67 mm bar capacity. The rigid, European-built machine is designed for continuous or series production of precision turned parts. Solid base casting ensures maximum rigidity and stability.

This leading line of cam-driven multispindles can accomplish a wide variety of precision metalcutting operations very quickly, consistently, and accurately. The machine includes six frontal slides with up to 142 working strokes, and six cross slides plus four compound slides with clamping, and bar stop in the 6^th station. An independent cam controls each slide. Stroke is adjustable on the rocker arm of the corresponding drive. The 667 machines are provided with different spindle speed ranges (200 to 3200 rpm), depending on material type and size.

Through the Hirth coupling with the spindle drum being fine bored in the casting positioning errors are eliminated. Another development includes the Maltese cross that smoothes precise indexing to increases the accuracy and longevity of the machine tool.

These machine tools are designed for precision, safety, and long, reliable operation. Four safety clutches prevent the slides from overloading. Spindle drum locking is accomplished by a Hirth coupling for ultimate concentricity, repeatability and precision. 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 Siemens variable speed motors and the machines are controlled through a SIMATIC S7-300.

To accomplish nearly any operation, the machines can be provided with a wide range of optional equipment, including NC drive of the pick-up spindle, bar stock feeding and clamping in the third station, attachments for high-speed drilling, reaming, tapping and broaching, and multi-spindle drilling heads on the frontal slides.

“Because ZPS America is our 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, the 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 that have worked multiple years at the factory and prompt factory warranted spare parts are very important to multispindle users.”

ZPS is a leading producer of multispindle cam driven machines, with more than 350 operating in the U.S. alone. In all, the company offers ten different models of exciting high precision cam multis. As of May 2009, ZPS America became 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.

Founded in 1903 for the production of shoe machinery, ZPS started to build multispindle machines in the 1950s and was acquired by the TAJMAC Group in 2000. Today, the company employs more than 2,500 associates globally and sells its CNC lathes around the world.

TAJMAC Group has operations in Italy, Czech Republic, France and USA. In addition to the ZPS multispindle CNC machines, the Group produces a wide array of metalworking machine tools including machining centers, Swiss turning machines, automatic lathes, gantry-type milling and turning centers, special machines as well as contract manufacturing for other machine tool suppliers. TAJMAC-MTM, the headquarters of the group, develops concepts for turnkey CNC multispindle lathes and machining solutions. www.zpsamerica.com
