USEFUL INFORMATION
Resharpening the Diamond Cutting Tool
Due to the complex process of manufacturing the cutting tool, it is cheaper to
purchase a new tool rather than try to rework the existing tool. Contact your
distributor or local shop for information on obtaining a new cutting tool.
Direction of cutting passes
When cutting move the bit from the right to the left and back. You can repeat
this operation as many times as necessary until the surface of the comm is
smooth.
Depth of cut
We recommended you adjust the cutting depth only one notch per pass.
Minimum comm diameter
You can cut the comm as long as there is a visible copper layer.
Number of cutting passes
You can run the bit across the comm as many times as necessary until the
desired cut is achieved.
For the automatic comm lathe we recommend you run the cutting tool across
the comm 2-3 times at maximum speed, then 1-2 times at minimum speed to
finish.
Length of cut
Adjust the comm lathe's adjustable stop screw to keep the cutting tool a safe
distance from the wiring tabs. Never hit the tabs! This will break the cutting
tool.
Cutting fluid and lubricant
The combination of Hudy Comm Lathe + plastic clips + Diamond Cutting Tool
makes a perfect cut without using cutting fluid or lubricant. However, you may
use any cutting fluid if you want to.
If you are using a Hudy Comm Lathe with hardened V guides, lubricate the
contact area with graphite powder to reduce friction between the guides and
the armature, and extend the lifetime.
