TURNING

We perform turning of large industrial components, focusing on critical parts that require stability, precision, and repeatability in machining.

We have:

  • Lathe Icon Vertical lathes, especially suitable for heavy and large-volume parts.
  • Large diameters, with turning capacities up to 2,000 mm.
  • Critical parts intended for industrial machinery and high‑demand applications.

QUALITY

Precision verified at every stage of the process

01

Each part is inspected during machining and validated according to the drawing before delivery, verifying tolerances, geometries, and functional surfaces in large components.

02

Dimensional control and 3D inspection are carried out internally, ensuring full process mastery in critical and high‑demand parts.

A strategic acquisition

In 2025 we became part of the OTSABIO industrial group as a specialized unit in large‑size and high‑precision machining, integrating into a consolidated industrial structure.

This incorporation allows us to expand production resources, technical capacity, and project scope, taking on larger and more demanding work within a single organization.
