03 / 05 Quality

Measured,
not assumed.

We are ISO 9001:2015 certified. Material is inspected before, during and after machining, so every part that leaves the shop is proven to spec.

Quality assurance

Inspected at
every stage.

RENISHAW probing and TESA metrology, inspecting material before, during and after machining.

Beyond standard inspection tooling, RENISHAW probes measure tools and features in the machine, while TESA altimeters verify heights, diameters, hole spacing, steps and groove widths.
