Processing center processing oblique oval
For example, your circular tolerance to be controlled in the 2 silk, then you use the cutter is extremely difficult to milling out, because the milling circle is theoretically irregular circle
Second, the workpiece is not fixed clamping tight, which was moving during the process, resulting in the final milling into the oval.
If the oval deformation is very powerful, there are several possibilities, the arbor is not installed, or the arbor itself is not good, causing the swing is too large, naturally processed out of the oval.
First of all do not know what you have that round there is no, if not just through the hole, it does not matter, if there is, how much tolerance is.
