Custom CNC machining services for precision metal parts. Grinding, lapping and treatments

Each production starts from technical analysis of the customer’s drawing. Sarbo technicians evaluate geometries, materials, tolerances and production volumes, defining the optimal machining cycle. This industrialization phase allows us to reduce waste, optimize time and costs and guarantee repeatability and quality of the final product.

Sarbo collaborates with leading European producers of certified bar material. Bars in brass, free-cutting steel, stainless steel, aluminum or bronze alloys are chosen based on mechanical characteristics and the intended use of the component. Each batch is traced and accompanied by certificates of conformity.

This is the heart of Sarbo’s production process. Thanks to a state-of-the-art machine park, consisting of multi-spindle lathes, twin-spindle lathes, CNC turning centers and sliding headstock lathes, we manufacture complex components with tolerances up to ±0.01 mm. Lean Production logic and OEE (Overall Equipment Effectiveness) monitoring guarantee efficiency and process continuity.

For components requiring even tighter finishes and tolerances, we perform grinding and lapping. These operations allow us to obtain perfectly uniform surfaces, precise couplings and controlled sliding, fundamental in sectors such as medical, hydraulics and pneumatics.

Parts are subjected to vacuum washing with modified alcohols and ultrasonics, a technology that ensures complete removal of residues and contaminants. This process is essential to guarantee the cleanliness and technical compliance of components intended for sensitive sectors such as medical and automotive.

In collaboration with qualified partners, Sarbo performs or manages heat treatments (to increase hardness and wear resistance) and surface treatments (zinc plating, nickel plating, anodizing, burnishing, passivation). Each treatment is chosen to improve mechanical strength and component durability.

All parts undergo 100% or sampling controls, based on customer specifications. We use three-dimensional CMM measuring machines, optical systems, roughness testers and automatic sorting equipment. Sarbo’s quality system is ISO 9001:2015 certified, and each part is traceable throughout the entire production cycle.

Component packaging is customized based on customer needs: from standard packaging to custom packaging with dedicated labeling, shock protection or technical bagging. The goal is to preserve machined surfaces, guarantee part integrity and facilitate subsequent handling or assembly phases. Thanks to an integrated logistics management system, Sarbo ensures fast delivery times.
