To rotate the REV eccentric bushing easily for alignment corrections, we recommend that the operator oil the bushing when the tool is assembled.
If an alignment error is detected on the processed workpiece and a correction needs to be made by rotating the eccentric bushing, we recommend first of all loosening screws (10) and (11) and then screw (8). When the correction has been made, proceed with tightening the first screw (8) and then screws (10) and (11).
It is advisable, but not essential, to widen (as precisely as possible) one of the threaded holes on the boring bar hatch so as to insert a larger flat point grub screw (10) and therefore guarantee a large supporting surface and, accordingly, perfect tool positioning. In particular, we suggest using a 16 mm screw or larger.
We recommend making sure that all screws have the required surface for clamping the tool perfectly flat and in no way damaged or deformed. Otherwise, immediately replace with new screws.
During assembly, the screw with spherical end (9) must be tightened all the way without forcing and then unscrewed by two revolutions so that the spring remains loaded on the tool. These screws, in fact, do not clamp the tool on but simply hold it in position during eccentric bushing rotation.
