3.10 Micro-adjust boring head
The micro-adjust boring head offers the possibility to micro-adjust readily available
off-the-shelf square shank tooling for boring. The micro-adjust travel is 0.5" (13
mm), and the ability to slide the tool without having to change the setup provides a
total tool travel of more than 2" (51 mm) per setup.
To set the tool to the desired diameter, simply feed the dial screw until reaching it
and then lock the middle dove tail set screw with the provided T handle hex drive.
Each division in the dial screw resolves in 0.001" (0.025 mm) change in diameter.
The dove tail adjustment set screws are set to the correct load by CLIMAX and
should not be necessary to re-adjust them. These set screws have Vibratite-VC3 in
order to avoid losing tension during vibration. The lock also has this compound, and
it might be necessary to re-apply it occasionally, if necessary.
The BB6100 micro-adjust boring head comes with a 3/4" (19 mm) square shank tool
holder. A bolt-on shim is provided the 3/4 tool holder so that it can be easily
converted to a 1/2" (13 mm) tool holder.
To set up leading and trailing, simply shift the boring heads against the mounting
screws in opposite directions.
There is a small set screw that stops the tool carriage from being removed from its
holder, and the boring head should never be operated without it on.
Proper maintenance would involve cleaning and lubricating the dove tail surfaces and
the dial screw threads and groove, and if the lock set screw feels loose after a while,
applying the provided Vibrative VC-3.
