■Engine machining equipment

Machining lines supply parts to the engine assembly process. Machining is performed to prepare casted or forged parts such as cylinder blocks and cylinder heads for assembly. This process requires a very high level of precision, sometimes with a tolerance of microns. Our machining lines are equipped to carry out such detailed operations.
