Precision machining · Granollers · since 1974
The part,
in microns.
We turn and mill metal and plastic parts to tolerances as tight as ±0.005 mm: five microns. From a single prototype to 50,000 parts a year.

A 9,400 m² plant in the Vallès.
38 CNC machines, 12 of them 5-axis, running three shifts. Josep Rierol opened the workshop in 1974; today it is run by Carla Rierol and Andreu Pons.

Four processes, a measured limit for each.
The tolerance bar is proportional: the shorter the bar, the finer the limit.
Four sectors, parts that allow no deviation.

Dimensional inspection in a room at 20 °C ± 1 and scheduled delivery.
We measure at 20 °C ± 1.
The coordinate measuring machine sits in a separate climate-controlled room. 20 °C is the reference temperature of ISO 1: the dimensions on the drawing refer to it.
How we inspect →Audited, with customers in four countries.
