SEMT Pielstick is a diesel engine manufacturer based in France. They have been making diesel engines for over 30 years and have a long reputation for quality. Some of the companies that regularly use ‘Pielstick’ engines in their products are Rolls Royce, Fairbanks Morse, Hyundai Heavy Industries and DHICO (Doosan Heavy Industries Construction Co).

These engines are used all over the world in a number of different applications. We have recently committed significant resources to the design and development of a process for machining the fuel pump seats on a Pielstick engine.

This process involved designing a three axes milling rig. The requirements were that the rig allowed right and left hand milling heads. This was to ensure that the corners could be machined flush on adjacent bulkheads, negating the need to remove the cylinder heads when machining.

The modular design of the rig we designed allows for a very fast set up time and quick turnaround. As a result we are now able to offer a comprehensive Pielstick fuel pump seat machining service. This includes surveying the engine prior to machining, and the full in-situ machining process.

If you’d like any more information about our Pielstick fuel pump seat machining service, or any of our other workshop services, please don’t hesitate to give us a call.
