The main business is the machining of engine blocks in situ.

This means for example:

• Repair of the liner landings by just skimming them or make a repair ring or shim into the block
• Machining of the upper and or the lower bores for the cylinder liner sealing surfaces to mount a repair sleeve in the block.
• Design and manufacturing of the repair rings
• Line boring of the main, or cam shaft bearing pockets
