— I've machined with both a grinding wheel and a milling machine, and I've found that the grinder is the more accurate machine tool. If you just want to remove material, either cutting tool will do, but you'll need the grinder if you want close tolerance in your parts. That's why grinding is preferred for more precise manufacturing processes.
