Crankshaft Repairs£º
Deyang Marine Engineering can provide a full range of equipment for orbital machining, superfinishing and polishing journals in the range 125mm to 1100mm in diameter. Full quality in accordance with OEM tolerances is assured. As an example we can conduct crankshaft journals 0.15mm/metre straightness to shaft axis, 0.02mm roundness and parallel with a surface finish better than 0.2¦Ìm Ra.
Axis tolerances achieved by electronically controlled level systems.
Diameter controlled by calibrated micrometer which measured and recorded.
Flatness controlled by engineers' blue.
Crack detection via Magnetic Particle Inspection system.
Hardness checked by using portable electronic devices..
