摘要

Even in the world of long-running, high-volume production on cam-driven automatics, quick-change tooling makes sense. Cam-driven, multi-spindle automatic machines are still the epitome of efficient, high-volume production equipment for small precision turned parts. When it comes to spitting out parts in quantities in the thousands or even millions, Davenports, Brown & Sharpes, New Britains, Acmes and other cam-driven machines excel in terms of parts-per-hour or other measures of cycle time. However, the changing manufacturing landscape in the United States - JIT and smaller batches - makes it challenging to use equipment originally designed for high-volume jobs. Faster setups are crucial to increasing a machine's flexibility. Traditional multi-spindles are difficult to change-over and setup, requiring a high level of skill that is becoming increasingly scarce. The setup time for some multi-spindle machines, for example, can take the better part of a day, while replacing worn tools can also be time-consuming and complex.
