HelloI have run into the problem of cracked woodworking knife holding rotor and would really appreciate opinion of professionals. Machinery has been in service since 2007 and has been used for 16 hours a day since that. It is most likely that this part should be replaced sooner or later as it is under immense dynamic loads and possible that cracking has occurred due to metal fatigue. I am currently looking for a temporary repair solution, so that I could delay purchasing of this expensive component. What I know is that the disc is made out of C45 steel and as I understand this grade of metal hardens if any thermal effects are applied. This eliminates the option of simply welding , as the hardened part would most likely crack again. I have been thinking about some machined solution for keeping the crack closed and preventing it from moving around. I have thought about using lock n stitch threaded inserts. What would be your opinion and take on this problem? I can mention that the disc is 1300mm in diameter, about 50mm in height and weighs about 400kg. Also I will try to attach some pictures of the crack, sketch of the cracked place.
