Today, a crankshaft grinding machine is undoubtedly one of the most, and maybe even the most expensive item in the entire range of engine shop machines. Moreover, this item is also the most accurate, since grinding accuracy is no longer fractions of a millimeter, but microns. And in general, for a grinding machine, an accuracy of 5 microns is somehow not even a conversation about anything (because it should be more accurate). Unfortunately (or fortunately), the times when you could grab an ancient machine from the distant Soviet Union for next to nothing are long gone. Today, you can no longer find such machines, and they do not meet modern requirements.
You can already hear exclamations: how come they do not meet? What if you look for them? Indeed, it would be nice to understand all this and find out what crankshaft grinding is and how to deal with it…
