CASSAGNAUD PROPULSION is specialised in the realisation of onsite machining.
Types of machining
- Bore (cylinder housing, stern tube, bearing housing …).
- Machining of flat circular surface.
- Machining of conical bore.
- Grinding of flat circular surface.
- Machine centred by laser aiming (external machining references).
Unlike in-shop machining operations, on-site machining requires a specific machine designed to be directly attached to the workpiece. Therefore, it is sometimes necessary to manufacture specific adaptation parts.
The main in-situ machining is carried out on the following elements:
- Diesel engine (cylinder housing, entablature and crankshaft bearing).
- Ship propulsion system (shaft line bearing, stern tube, chair, intermediate bearing, propeller and propeller shaft).
- Vessel maneuvering system (bow thruster, rudder bearing, rudder tube, rudder).
- Compressor bearing or cylinder housing machining.
- Roller bearing bearing bore.
- Screed machining (ramp, conveyor belt, door …).
Benefits of on-site machining
Following a fault or during a scheduled technical stop, it may be necessary to perform one or more machining (s) on a relatively large or difficult to extract part. As a result, in-situ machining makes sense. This limits dismantling, handling, transport in a workshop equipped with sufficiently large machines and thus reduces costs and downtime. In addition, when machining on site is performed with a powerful machine and well adapted, it allows for work as accurate as factory.
In some cases, there are no other alternatives to in-situ machining, as the intervention must be done directly on the structure of the installation or on the hull of a ship.
