I've been running a Hurco VM20i (2014) for a few years with good results and recently picked up a used 2007 VMX30 for a great price. The machine works really well, except it leaves a wavy surface finish when side milling. Face milling looks great, it's only side milling that has an issue. The machine interpolates a circle just fine (aside from the wavy surface finish) and it's to size and not out of round. It's definitely the machine/control as I've eliminated all other variables: I can take the same tool, holder, program, material, etc. over to my other Hurco and the finish is great. Plus this happens on all parts, different tools, holders, etc. The programable surface finish (G05.3) is set to 10 in this particular program, so that's not the issue. Any ideas?
