High-volume production of small, slender parts: machine tool choice Which machine gives maximum production efficiency for small, long, and slender turned parts? Choose the correct lathe type.

Concept/Approach
Sliding headstock automatic (Swiss-type) lathes support the work with a guide bushing very close to the tool, ideal for producing long, slender, small-diameter parts at high rates.

Comparison

• Watchmaker's lathe: precision hand/bench work, not highest throughput.
• Multispindle/capstan: high productivity on short parts; less ideal for very slender lengths.

Final Answer
Sliding headstock automatic lathe (Swiss-type)
