Steel turning

A&B works on different kinds of steel turning, to produce and treat cnc steel parts. The most commonly requested steel grades, and therefore the mostly turned, are the free cutting steels: better known in Italy under the acronyms AVP, AVZ and PR80, these steel grades are used for motor shafts for self-starters, fittings, brake fittings for the oil-hydraulic industry, grease nipples, bearings, screws, nuts, bolts, for the furniture industry and for small metal parts in general.
Among the stainless steels we find AISI 303, 304L, 316L and 430F which are broadly used in the chemical, petrochemical and food industries, as well as if the production of paper, in the bio-medical and pharmaceutical industries, in the automotive sector, on the off-shore platforms, and can be found in all our home appliance, in the housing sector and urban design. We can offer personalized solutions in steel turning processes: we also turn other steel grades if the component shape and dimension falls within the type of components we turn.
