4.1 The angle of cut is adjusted by rotating the mounting bar assembly, complete with
bedknife, so that it is presented to the grinding stone at the required angle. Take the weight
of the assembly on the control lever, loosen lock-down lever then use the control lever to
rotate the assembly to the required angle, tighten the lock-down lever.
4.2 Applying a cut
The Bedknife blade is adjusted parallel to the grinding access. The mounting bar is
paralleled by drawing the mounting bar / bedknife assembly towards the grinding stone, by
means of the two handwheels
Once the bedknife has been set, the cut is applied via the single point feed handwheel on
the grinding head/carriage.
Handwheels must be moved equal amounts. If one is moved considerably more than the
other (during set up for instance) mounting bar misalignment could result in the slide block/
feed screws jamming.
4.3 Rotate the mounting bar so that the bedknife is vertical.
4.4 If not already done, release the motor unit from the traverse chain using the lever at the
front left hand side of the motor unit.
The guard mounted on top of the motor unit can be adjusted so that you can see the
contact point of the stone to the bedknife. Slacken the locating screws to move this and
retighten. The guard should only be move the minimum to allow visibility. This will need
adjusting as the stone wears over time.
Scratch across the top face of the bedknife (by hand with the grinding motor off, or with
experience with the grinding stone motor running).
Adjust the mounting bar so that the grinding stone scratches the full worn face of the
bedknife from edge to edge in one spot (You have effectively found the datum relationship
between reel and bedknife).
4.5 Press reset button to set the current position of bedknife
– left hand “Where you are” display shows zero. Now the
bedknife’ blade and machine are both set to 0°
(On a brand new bedknife, scratch across the new face and reset display to 0°, then hold
reset button whilst using the + and - buttons to adjust the “when you are” display to the
correct angle for that bedknife according to it’s size:
–7°, small units; –9°, medium units; –12°, large units.
As the blade has no wear the angle will be correct as applied by the manufacturer).
