4.3 MANUAL BACK GAUGE.
The back gauge consists of a left and right hand shafts fitted
with a rack and pinion. Mounted on each shaft is a sliding
block that slides along the rack shaft carrying the back gauge.
The racks are connected by a shaft and handwheel. When
turning the hand wheel the back gauge is moved in and out.
The shaft can also be used for adjusting the synchronizing of
the two ends of the back gauge to keep them parallel.
The right rack shaft is fitted with a scale with graduations of
0.5mm. When installing the machine for the first time or af-
ter grind ing the blade, you should carefully adjust the “zero”
position,
The two sliding blocks are fitted with clamping handles. After
the adjustment of the gauge distance, re-clamp the handles.
Digital Readout
Some machines are fitted with a digital readout on the back-
gauge (Fig.4.2). The adjustment can be set using the display.
The display unit can be changed between inch or metric and
allows for “Zero” to be selected in any position.
It also has a button (ABS) which allows a switch between
absolute and incremental measurement.
E.G. First cut is at 100mm, and the second cut is at 400mm
when ABS is pressed then the total of the two is displayed as
“500”mm.
The digital display is attached to the right hand shaft and does
not need to be reset as the scale can be “Zero” in any position.
After the adjustment of the gauge distance, re-clamp the
handles.
