Cam-Driven, Six-Spindle Lathe Offers Speed, Reliability

ZPS America offers a cam-driven, six-spindle automatic lathe with a 20-mm bar capacity. The rigid machine is designed for continuous or series production of precision-turned parts. A solid base casting ensures maximum rigidity and stability, the company says.

The ZPS line of cam-driven multispindles is said to accomplish a variety of precision metalcutting operations quickly, consistently and accurately. The machine includes six frontal slides with as many as 110 working strokes; six cross-slides; four compound slides with clamping; and bar stop in the sixth station. An independent cam controls each slide. Stroke is adjustable on the rocker arm of the corresponding drive. The machine is available with different spindle speed ranges depending on material type and size.

Designed for precision, safety and long, reliable operation, the machine features four safety clutches prevent the slides from overloading. A Hirth coupling is said to provide repeatable, precise spindle drum locking. A barstock guide is standard, and the machine can also include automatic bar loaders and bar magazines for unattended operation.

Spindles are driven by Siemens’ Simodrive variable-speed motors, and the machines are controlled through a Siemens S7. Optional equipment includes NC drive of the pick-up spindle; barstock 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.
