OUR IN-SITU MILLING SERVICES

The two images below relate to an extensive metal stitching and milling exercise. Following a large diesel engine failure which was severely damaged, leading to major bedplate and cylinder block casting breakages. In-situ Machining Solutions. were invited by a leading diesel engine manufacturer to conduct a feasibility study to establish whether the damaged castings could be reclaimed as no pre-used or second hand bedplates or cylinder blocks were available after a world wide search. Subsequent to the feasibility study it was confirmed that a repair solution was viable and In-situ was awarded a contract to refurbish both, bedplate and cylinder block. New cast iron parts were produced and profiled to templates taken during the initial study prior to them being fitted, metal stitched and finally machined to the damaged areas of the engine. These photographs show the milling set up’ s and the milling work being undertaken. An allowance had been left on the fitted parts for final machining to enable these new parts to be machined perfectly flat and blended into the existing joint faces of the bedplate and cylinder block. The two pictures below relate to work being carried to the top plate of a steel fabricated cylinder block of a large marine diesel engine. Due to many years in arduous service, areas in way of the fuel pump locating areas on two of the main engines ( 18 in total) had worn/ fretted to a degree that engine efficiency and fuel usage was being compromised. In-situ Machining Solutions were contracted by the ship repairer to remedy the worn fuel pump seating areas. Since access to the top plate surfaces on this engine is very restricted, particularly when the cylinder head is in place, a special purpose milling machine was produced to undertake the milling work. 1mm + / - 0.025 was removed from each of fuel pump seatings to make good the wear/ fretted areas. Shim plates 1mm thick were produced to make up for the material removed by machining. Photographs show the machining equipment in place ( left) and several fuel pump locations after machining ( right) .
