Lifter Bore Mode 3 Axis
Lifter Bore programs are built the same as described in the Bore Mode 3 Axis. Only the differences will
be discussed in this section.
In / Out Zero
The In/Out zero position for Lifters is the center line of the Cam Bore. An easy way to find the center of
the cam line is to use the electronic probe. The following is an example of this procedure. Install the
probe into the holder and the holder into the spindle. Bring the probe down until it is in the approximate
center of the cam Bar Vertically. Press the Vertical Zero button now (this is only a temporary Vertical Zero
position). Using the In/Out handwheel bring the probe up to the Cam Bar until it lights. Press the In/Out
zero button here. Move the spindle up enough to clear the Cam Bar, move the probe to the other side of
the Cam Bar. Bring the vertical down to the zero position. Hand wheel the probe into the Cam Bar until
the light comes on. Note the In/Out position reading. Divide this reading by two. Bring the spindle up
until it can clear the Cam Bar. Use the In/Out handwheel and move the In/Out position until it matches
the divided number. This is the center line of the Cam Bar. Press the IN/Out Zero button now. The In/
Out zero position has been set. The following illustration visual shows the above description.
Start Boring Height
Pay particular attention when setting this height, there are often protrusions in the casting that will not
allow the End Mill to travel unobstructed all the way to the start of the lifter bore. It is safest to set the
Start Boring Height above the Deck.
Lifter Bore Angle
Rottler has specific Lifter Bore spacers that are installed on the Cam bar to set the correct angle for lifter
boring when using the Performance Fixture.
