If a shop is running high volume parts and needs the ability to run lights out, then a Swiss type-lathe is totally worth it. Swiss lathes are great for large quantity batches and family groups of parts. Changeover on a Swiss lathe is minimal, especially when running a family group of similar style parts together. With the exception of changing out collets, an operator can load a new program and start cutting in typically a few hours at the most. A family of parts means that if a lathe is running a particular part, and a new part comes along that is similar to the existing part, it is easier to set up because the parts are similar enough that the machine is already tooled-up to be able to switch from one part to another with minimal downtime for setup. Another added benefit of Swiss machining are components that are reliably turned to meet high accuracy specifications. Cutting these on a Swiss, as opposed to a conventional lathe, reduces costs related to returned parts, such as shipment and restocking expenses as well as delayed lead time and retooling costs.
