Yesterday I was using an econo-import 3” fly cutter with econo-import (1/2”?) tool shank & carbide insert to fly cut .007” off some 6061 aluminum. The mill is a PM-25MV on the factory stand bolted to the concrete floor with 2 bolts.
The quill was locked in the fully retracted position the whole time. After dialing in the cut, I would tighten the two z-axis locking bolts.
While it was cutting, both z-axis locking bolts would loosen enough to allow the head to drop. This would cause the DOC to increase up to .025” or so (too much for a fly cutter!).
Can you guys think of any way to fix this problem?
