Cylinder Heads Marked With Critical Information

摘要

When the high-speed Richter UniGrav~(TM) programmable peen marking machine was first introduced by Columbia Mlarking Tools in 2001, there was immediate interest, particularly by the automotive industry, in the machine's versatility and ability to be used as a stand-alone machine in low volume applications, as well as integrated into high production systems. Recently, Ford Motor Company took advantage of the UniGrav technology to place critical identification marks on the aluminum cylinder heads of the new 500 HP Ford GT DOHC engine. The special marking machine designed and built by Columbia Marking Tools peen marks numbers on the cylinder head bearing caps to correspond with those of the matching cylinder head position. These are critical marks to insure that quality and proper assembly sequence is maintained. Improper assembly of bearing caps can ultimately cause an engine to seize up.
