Surface Grinding Machine for Grinding of Sealing Surfaces

Surface grinding machine like CPM eliminate and prevent water and gas leakages. Thanks to in-situ grinding and milling of cylinder heads, liners and engine blocks, valuable time can be saved.

Grinding and machining of sealing surfaces according to engine makers’ specifications is very important as failure to do so means jeopardizing engine performance. Lower engine performance and possible down-time is costly and should be avoided. The good news is that there is a variety of machines available to make maintenance accurate and efficient.
