667 6-Spindle Automatic Lathe

May 01, 2011

ZPS America LLC announces its newest cam-driven 6-spindle automatic lathe with 51 to 67mm 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.

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 6th 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. The maltese cross smoothes precise indexing to increases the accuracy and longevity of the machine tool. Another new development by ZPS. 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 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 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 that have worked multiple years at the factory and prompt factory warranted spare parts are very important to multispindle users."

Related Glossary Terms

  • broaching

    broaching

    Operation in which a cutter progressively enlarges a slot or hole or shapes a workpiece exterior. Low teeth start the cut, intermediate teeth remove the majority of the material and high teeth finish the task. Broaching can be a one-step operation, as opposed to milling and slotting, which require repeated passes. Typically, however, broaching also involves multiple passes.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • computer-aided manufacturing ( CAM)

    computer-aided manufacturing ( CAM)

    Use of computers to control machining and manufacturing processes.

  • lathe

    lathe

    Turning machine capable of sawing, milling, grinding, gear-cutting, drilling, reaming, boring, threading, facing, chamfering, grooving, knurling, spinning, parting, necking, taper-cutting, and cam- and eccentric-cutting, as well as step- and straight-turning. Comes in a variety of forms, ranging from manual to semiautomatic to fully automatic, with major types being engine lathes, turning and contouring lathes, turret lathes and numerical-control lathes. The engine lathe consists of a headstock and spindle, tailstock, bed, carriage (complete with apron) and cross slides. Features include gear- (speed) and feed-selector levers, toolpost, compound rest, lead screw and reversing lead screw, threading dial and rapid-traverse lever. Special lathe types include through-the-spindle, camshaft and crankshaft, brake drum and rotor, spinning and gun-barrel machines. Toolroom and bench lathes are used for precision work; the former for tool-and-die work and similar tasks, the latter for small workpieces (instruments, watches), normally without a power feed. Models are typically designated according to their “swing,” or the largest-diameter workpiece that can be rotated; bed length, or the distance between centers; and horsepower generated. See turning machine.

  • numerical control ( NC)

    numerical control ( NC)

    Any controlled equipment that allows an operator to program its movement by entering a series of coded numbers and symbols. See CNC, computer numerical control; DNC, direct numerical control.

  • tapping

    tapping

    Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
