4.7 Start the grinding wheel motor and slowly hand traverse the grinding carriage along the
length of the bedknife, with very light contact.
Set the traverse stops on the front of the machine chassis, so that the grinding stone just
clears the ends of the blade.
Preliminary setting up passes, with hand traverse during set up, may be made without
coolant. Similarly, initial grinding can be carried out without coolant. For the latter stages, a
moderate ow of coolant should be directed onto the bedknife, as close as possible to the
point of contact with the grinding stone.
Ensure that the ground surface is parallel along the whole length of the bedknife.
With the auto traverse engaged, grind the bedknife until it “sparks out” (only occasional
sparks seen as grinding stone passes the blade – no real metal removal).
4.8 Grinding the Front Face of the bedknife
Rotate the mounting bar forwards, continue through 0°,
through 90° until both displays show Front when the front
face has reached 5°.
As for the top face, grind the front face parallel from end to end.
Check that the cutting edge is sharp and remove any burr as necessary.
4.9 Unbolt the bedbar from the bedknife mounting brackets. Switch off the electromagnets and
remove the bedknife assembly from the Anglemaster.
