Asquith Butler are world leaders in the design and manufacture of Auto Indexing Heads. The automatically Articulating heads can be used to allow machining in a variety of different angle and planes. This is particularly useful to minimise multiple workpiece settings and transfers from machine to machine. Particularly useful for large prismatic milling and boring of components for the aerospace, oil and gas, and automotive manufacturers.
