· Check the tool holder for lateral play. Lateral play often causes ridges and matching grooves when a rotor is resurfaced. To
check for lateral play, grab the tool arm assembly and try and rotate it diagonally. There should be no motion. If there is motion,
you will need to adjust the gib.
Brake performance is dependent upon rotor surface finish as well as minimizing lateral run-out. The
Pro-Cut lathe is designed to give you a superior surface finish on any rotor as long as proper maintenance
is followed.
Minimizing vibration during machining is the key to high-quality surface finish. It is critical that all con-
tact points between the rotor and the lathe are secure – specifically, the connections between lathe and
adapter; the slide plate and the lathe; the cutting head and the plate; and the tips and the tool holders.
Looseness in any of these areas will compromise lathe performance and surface finish.

TROUBLESHOOTING ASSURING A SMOOTH FINISH
The Pro-Cut VBG640 should
provide a smooth surface
finish on every cut, free of
chatter, tone, or roughness.
If your machine leaves a sub-
standard, “chattery” or rough
finish, you need to find the
problem. The following pages
are the common sources of
poor surface finish and ways
to remedy the problem.
NOTE
· To adjust the gib, first loosen all four set screws by freeing the 7mm lock nut and loosening the allen set screw. Then remove the
plate and gib completely, and clean the contact surfaces. Use steel wool or a sharp tool if buildup is difficult to remove. Once
these surfaces are clean, slide the plate back on and perform the adjustment. The procedure is to locate the plate in the middle
of the rail, and then tighten each allen set screw individually until you feel it snug against the gib. Lock the screw down with the
7 mm lock nut. After tightening each nut, slide the plate to make sure you have not over-tightened the screw. If you have, then
the plate will be seized and you will not be able to force it to move. When the gib is adjusted properly, the plate will have some
resistance as it slides. There will be no lateral movement possible.
· To re-attach the feed block, position the slide plate as far in as it can travel, and wind the feed block in using the feeder wheel.
This ensures that the feed block will mount squarely. Wind the head back out and the machine is ready to go.
