Dressing A Stone - Axminster AW8G2 User Manual

Fig 10
!
If the grindstones wear unevenly, producing crests, dips or rounded edges, they
should be dressed out using a suitable wheel dressing tool. (A selection of stone dressing
tools are available in the Axminster catalogue.)
Switch the grinder on and allow it to run for at least one minute. Rest the dressing tool on
the tool rest and advance it to the stone until it touches the maximum diameter; gently move
the dresser back and forth across the face of the stone until all irregularities have been
removed and the edges of the stone are nice and sharp.

PLEASE NOTE
This is not a procedure that can be
rushed, it must be carried out
slowly and steadily.

Changing a grinding wheel...
Reset the spark guards & tool rest for "setting up the
grinder" instructions. Reconnect the grinder to the
mains supply, give the grinder a 'short burst', by
switching it on and off quickly. Check the grinder is
not subject to any undue vibration . If the grinder
does vibrate, strip it down again and check that the
bush (if fitted) is correctly positioned and is the cor-
rect size for the stone and the spindle. Check the bore
of the stone is correct. If these all seem correct refit
and carryout the 'quick burst' procedure again. If the
machine is still vibrating, discard the stone and
replace with another one. Run up to speed normally.
Leave the machine running for at least one minute
before carrying out any work. Apply a workpiece and
check that the spark guard is correctly positioned and
that the tool rest is securely fixed.
If necessary dress the new stone lightly to ensure a
'good face' and concentricity.
