Manufacturers often cite lack of rigidity as the greatest single obstacle in successfully turning small diameter parts such as those produced on Swiss-style lathes. Invariably, marginal, or in some cases, complete lack of rigidity results in vibration issues. The vibration in turn, results in poor surface finish and often, parts that are out of tolerance. Recognizing the difficulties associated with turning small diameter parts, Nomura long ago adopted a manufacturing philosophy centered on strict design and development parameters aimed specifically at the inherent problems encountered in this type of machining.
