Hello, I'm looking to see if anybody else has any experience with this or if anybody has any thoughts on what might be causing it, so far our support lines haven't been able to help.
When milling with either the Roland 51 or 52 we are getting really noticeable parting line issues and the milling quality on the margin side of the parting line tends to be extremely rough and sometimes also has margin chipping. The results were even worse on the 52 and support had us send it back to Roland to have the Y axis ball screw replaced. The pictured results are from both mills and after the 52 was fixed. We have tried both 2019 and 2020 strategies in Millbox some provided by Zahn and some coming directly from Roland. So far those haven't made a difference. I have used Roland mills for over 10 years and have seen them mill much better than this and the fact that two different mills are getting the same results indicates to me that it is likely a strategy issue. I should also mention that we have tried different burs including what is recommended by Zahn (our reseller)
We have also done various other trouble shooting things such as calibrations and cleaning and greasing the poles that the milling part slides on (sorry for not knowing the technical terms here)
Anyways, any thoughts on what may be going on would be appreciated.
