This case study demonstrates our capability of realising a mass production facility in a very short timeframe. Within six months, Smithstown Light Engineering installed 24 Cincom sliding-headstock CNC bar autos. The major investment followed Smithstown’s receipt of a contract from a multinational medical firm for machining multiple variants of two types of endoscopic device parts from 303 stainless steel bar. Annual capacity is currently 18 million for the production of nine million assemblies. Having first identified the need in 2017, we machined sample parts on a 20 mm bar capacity Cincom L20 installed three years previously to fulfil another contract (which is still running) for turning a 316 stainless steel spindle for a medical delivery device. Discussions progressed and to develop the process further, we bought on-spec a 12 mm bar capacity Cincom L12, which is of more appropriate size for producing the endoscope parts in short cycle times. The lathe was installed in August 2017 in our second facility which had just been acquired and extensively refurbished.
