Internal Grinding

B&B Precision have dedicated Internal Grinding machines which allows us to grind intricate internal work including multi-diameter and tapered bores. We have in house capability to manufacture special jigs enabling us to hold items which would otherwise be difficult to hold in a chuck or on a permanent magnet.

Bores from 10mm (0.4″) up to 500mm (20″) in diameter can be ground up to 500mm (20”) deep. Internal Grinding ensures that the ground bores run true to the component face.

B&B have a CMM to check all critical dimensions and roundness and can produce bespoke inspection reports if required.
