Correct Grinding, Cause Of Faults And Correction - Westfalia 82 60 24 Original Instructions Manual

If longer grinding is necessary, take breaks for cooling
down. After grinding one side of the drill bit, secure the
control screw (5) tightly. This defines the same position
for the other side.
6. Loosen the lock screw (1) and take out the drill bit. Turn
it, so that now the other flank lies against the stop. Turn
back the adjustment screw (4) and repeat the grinding
process. If necessary, e.g. when the drill bit is much
worn, repeat the grinding process.
If this still does not achieve the desired appearance of
the drill bit point, repeat the grinding with the drill bit
pushed out further beyond the stop (by more than one
drill bit diameter). See further instructions about the
correct sharpening of drill bits in the chapter below.
Correct Grinding, Causes of Faults and Correction
 Despite machine assistance using the pre-set grinding
angles and movements, the correct grinding of a drill bit
definitely requires some experience, and particularly
care, during the handling of the drill bit.
 Below you will some hints about the correct grinding of
the drill bit and how to avoid faults. However, this infor-
mation cannot guarantee the correct grinding of the drill
bit – in the end, your own skill, adherence to the operat-
ing instructions, the state of the drill bit and the grinding
disc will determine the outcome.
