CNC turning: Turned-parts manufacturer uses sliding-head lathe instead of multi-spindle auto

摘要

Turned-parts sub-contractor iNRO is using the speed of its Star EGAS 20 CNC sliding-head lathe to produce some of the lower-volume work that might previously have been put on its six cam-type multi-spindle automatics. The result, according to founder and senior partner Roger Innes, is more economic production through shorter set-up times, allowing him to offer more-competitive prices, win extra business and prevent work going overseas. In the case of two stainless-steel components, mill-turning cycle times on the Star are actually shorter than they would be on the multi-spindle machines. Specialist fixings and fasteners for the construction industry, as well as precision turned parts for the leisure, defence, ironmongery and safety equipment industries, form the mainstay of INRO's business. Stainless steel accounts for 80% of the machined parts, with most of the remainder being made from steel, brass and aluminium. The company operates from 12,000ft{sup}2 premises in Chingford, and uses eight Star sliding-head lathes, as well as other machines.
