Also, if you think you are going to make round circles (g02 03) and not have problems, forget it. Part of the circle will be climb milling and it will make a big mess of the part, possibly break the tool etc. (Don't ask how I know:{(
Just some food for thought. |
My mill is almost brand new, so the screws are still tight. I'm guessing that it will last a long time, by then maybe I'll update to ball screws. Circle interpolating should not be a problem with this machine. Keep in mind that I'm not going to try and make accurate holes. Profile tolerances of .005in+ at minimum, usually more on the order of .015in. For accurate work I'll run a boring bar down through the roughed out hole. Mostly I'm looking to make parts with intricate outside profiles. i'm currently sending this out to another guy and I want this machine to make prototypes and test parts.
