Hinckley-based aero engine pipework specialist B&D Patterns is using a twin-spindle CNC lathe to increase flexibility and output. The front-loading Biglia B200F has the footprint of a standard CNC lathe and can carry out two operations sequentially with no floor time. For processes with a long-first and shorter-second operation, two parts can be machined simultaneously, with the second operation done on another machine. Parts are made from a mix of bar and forgings with 80% turning and 20% second-operation milling and drilling. The single-operator machine is as productive as two machines and two operators, its supplier says.
The Star SV-32J is designed for rapid mill-turning of complex components. Its supplier, A&SPrecision, says it combines the traditional precision, speed and flexibility of a sliding headstock lathe with the larger diameter bar capacity of a modern CNC lathe. It has a continuously rated 5.5kW 7,000rpm main spindle, an eight-station turret and a gang tool post with seven stations.
The Kitamura KNC series of two-axis CNC lathes offers automatic loading options ranging from simple gravity feed to integrated robot workpiece handling. The machines can be linked to barfeeders for turning from bar stock.
