Machining of steel, cast iron, and aluminum
FOS POLMO specializes in the mechanical machining of steel, cast iron, and aluminum alloys for the automotive, machinery, and industrial sectors. We perform precision machining of all key parts that make up a pneumatic compressor — such as crankshafts, compressor housings, connecting rods, valve plates, valves, valve strips, and other components requiring high accuracy and repeatability. We also machine turbocharger housings and technical parts with complex geometry.
The process begins with an analysis of technical documentation, preparation of the material or casting, and performing reference operations that give the part the appropriate reference points for further machining. At this stage, operations such as turning, milling, drilling, and preparation of mounting and technological surfaces are carried out.
The next stage is precision machining, which includes producing key dimensions, holes, seats, channels, mating surfaces, and elements that interact with other components. We machine steel, cast iron, and aluminum components, ensuring durability, precise fit, and stable operating parameters. The process may also include specialized finishing operations such as grinding, honing, or thermo-chemical treatment of working surfaces.
FOS POLMO also offers contract machining of metals and aluminum according to technical drawings. We manufacture parts and components in accordance with customer documentation, selecting the machining technology to match the material, dimensional, and functional requirements of the project. This allows us to produce both standard parts and custom components for the automotive, machinery, and industrial sectors.
