Elmax Engineering came to us with 6 intricate forming roller shafts that had been machined out of tolerance where the bearings sat on the shafts. The shafts are used as a mould to manufacture aircraft parts.
CMS made use of its machinery to rotate the shafts and then wrote a robot program to spray the areas required very precisely. A nickel composite material was used as this is very hard wearing so would last the lifetime of the tooling. CMS then sprayed a coating on all areas of the 6 shafts and they were then returned to Elmax for final machining.
CMS saved expensive machined parts from being scrapped as they were able to apply a coating that could be machined back so the shafts were brought back into tolerance. This saved the customer money and time as they did not have to be made from scratch. The reason cold spray is ideal for this use is because of the very low heat used in the CMS process so it will not distort the part. CMS allowed the parts to be turned around for the customer within 2 days.
