Machining

Our machining department offers specialisation in vertical and horizontal turning, broaching, drilling, milling and is an aid to the fabrication and welding function both during and after fabrication. Broadbent's particular skill lies in machining large complex components to the tight tolerances required for smooth centrifuge operation.
