The ship building industry reflects the national manufacturing technological level, which is now becoming the focus of the market. Among the key components of ships, the marine diesel engine is the core part of the ship building industry which promotes the development and innovation of lathe industry, in particular, the heavy-duty lathe and requires the measuring machine could be able to match the measuring requirements of large precision parts. The main components of the marine diesel engine are box type components, such as upper and lower crank case, connecting rod, flying wheel shell, crankshaft, cylinder cover etc. compared with other components, they feature large dimensions, more measuring items, high measuring precision etc. Therefore, Large size bridge measuring machine (View 15X X12 series) and large-size high precision gantry measuring machine (Discovery) are the best solution to complete the measuring for the components of marine diesel engine, in particular, the key engine body.

The engine body is the base of the diesel engine which supports the whole engine. All the components and auxiliary system are directly or indirectly connected to the engine body, forming the compact external shape that is easy to service. Therefore, the engine body testing is the most complex measuring, containing the most measuring items.

More importantly, the CMM could cover all the components to be managed in a unified way under the social mass production while the test efficiency and production efficiency are improved.

To sum up, large power and high speed diesel engine features high precision, complex structure and large measuring difficulty. During the application of the measuring machine, the users should consider such contents as calibration and application of probes, correction method of parts, application of multi-stepped plane in small plane, short benchmark solution, relation calculation skills, and correction method for problems in shape and position tolerance assessment etc.
