Our cylindrical grinding capability centres on the Jones & Shipman 1212 grinder supplemented by two Suprema CNC universal grinders for precision round finishes. These deliver micron-level concentricity on shafts, rollers and pins, with automated precision across steels, stainless alloys and non-ferrous metals.

We provide precision surface grinding using four Jones & Shipman 540L, three 540 and two 1400 grinders, each equipped with OptiDress or DiaForm wheel-dressing systems for complex profiles. These are complemented by Okamoto surface grinders (1000 × 500 mm and 600 × 300 mm). All machines are housed in temperature-controlled bays to minimise thermal variation, ensuring consistent, high-accuracy flatness, profiles and surface finishes across steels, stainless alloys and non-ferrous metals, meeting the tightest tolerances for tooling and sub-contract components.

Precision jig grinding is powered by our Moore 2C CNC jig grinder, featuring Heidenhain control for sub-micron positional accuracy, and a fleet of ten further Moore 2C jig grinders complete with all auxiliary attachments and high-rise columns. This setup allows us to grind complex bores, slots and contours in tool steels, stainless alloys and non-ferrous materials with exceptional repeatability, surface finish and concentricity.
