Set up of Traverse
The reversing bar is located in the aperture to the front panel of the machine. Rotate
hand wheels anti-clockwise to move grinding wheel away from reel, unscrew the traverse
engagement screw until it is released from the traverse chain, traverse the grinding wheel
by hand, using the Traverse Engagement Screw until it is at the extreme point of desired
travel. Ensure that the traverse reversing bar is also moved in that direction and slide the
reversing stop up to the grinding wheel traverse assembly and tighten. Move the grinding
wheel to the opposite end of the desired travel and repeat the operation ensuring that the
reversing bar has also been moved in the opposite direction. This is critical where the
grinding wheel cannot pass beyond the end plates if they protrude below the maximum
diameter of the reel.
NOTE On the EXPRESS DUAL it is not necessary for the whole width of the grinding wheel to
pass the end of the reel and it SHOULD NOT DO SO EVEN IF SPACE PERMITS (see
Fig. 6.4).
Ensure that the leading edge
of grinding stone passes the
end of the reel - but clearance
must be maintained between
stone and end frame of unit.
NOTE: The reversing bar will move approximately 1/2” (13mm) before the direction of travel is
reversed and will allow the grinding wheel to move with it. It is therefore
ESSENTIAL
that
this is taken into account when setting the maximum point of travel.
Should the reversing bar be dragged by the traverse assembly in the direction of travel
during the grinding processes, causing the stone traverse to reverse prematurely, it will be
necessary to adjust the reversing bar damper as indicated in the service bulletin (No.003).
