Multispindle Automatic Lathes Advance Precision Manufacturing

A multi-spindle automatic lathe is a precision turning machine equipped with multiple work spindles. Each spindle holds an independent workpiece, and a rotating drum indexes the workpieces through a series of machining stations. Because several tools cut different workpieces simultaneously, the machine can complete one finished part per cycle.

• Synchronized operation: Multiple workpieces are indexed through separate stations while tools work on them at the same time, allowing one finished part to emerge after each machine cycle.
• Higher output: Compared with single-spindle lathes, multi-spindle equipment can typically raise production capacity by four to six times when handling high-volume orders, according to the company.
• Integrated processes: A single machine can perform turning, drilling, tapping, milling and other complex operations, reducing the time required for secondary machining.

The combination of simultaneous cutting and in-machine process integration can reduce secondary-operation time and support a more continuous flow from raw material to finished part.

Davenport Machine, a machine tool builder with more than 130 years of industry history, according to the company, offers a line of multi-spindle machines for high-volume production. Its core models differ in control, rigidity and secondary-operation focus.

According to the company, the Model B has been in use since 1900, while the Chucker is aimed at secondary operations rather than primary turning alone.

Davenport's multi-spindle machines are designed to perform a range of operations beyond basic turning. The company lists forming, backworking, drilling, reaming, broaching, cross milling, flat generation, cross drilling, thread rolling, shaving, burnishing, polishing, keyway milling and grooving among the available processes.

That breadth of in-machine work is intended to limit the need to move parts between separate machines, reducing handling time and supporting a more efficient transition from raw material to finished component.
