Capability · heavy machining
Heavy parts machined to 0.03 to 0.05 mm form-position, workpiece to 50 t, documented
You send a casting, forging or weldment, or just the drawing. You receive a finished part with the material certificate, the CMM dimensional report and the NDT protocol where specified, under one PO. Workpiece to 50 t static, 30 t rotary, envelope 9 x 3 x 2.5 m. Stratosteel owns the outcome.
