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 and tool rest as 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 correct 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.
