2. Safety instructions
2.1 Care obligation of customer
The sharpening machine ERM.100/3 was designed and produced after giving due consideration to
danger analysis and after careful analysis of appropriate harmonized standards, as well as the
further technical specifications. It conforms to the status of the latest technology and guarantees
maximum possible safety.
However, the specified safety level can only be achieved if the necessary measures are taken during
operation. The care obligation of the customer includes planning these measures and controlling
their execution.
The customer must especially ensure that:
-The machine is used properly according to the specification (please refer chapter 1.
Production description);

5.2 Adjusting and installing the machine
5.2.1 Preparing the index plate
Turn the knob of the Hex socket loose, (photo 3) and remove the index plate (photo 5). To replace
the index plate turn the knob clockwise until the wheel screw in index plate is facing upwards. The
index plate needs to have the same number of grooves as the number of teeth of the Euroboor HSS
annular cutter (photo 4).
Photo 3
5.2.2 Inserting the index plate
Place the index plate on the axel (photo 5). Make sure that one of the grooves on the side you want
to use is placed against de spring-loaded selector. Tighten the index plate with the Hex socket (Allen
key 2.5) (photo 3). The sharpening machine have three index plates with five different grooves
(number of teeth 6, 7, 8, 9 and 10). This machine is suitable for Euroboor HSS annular cutters with a
maximum depth of 55 mm and a diameter of 44 mm.

5.2.4 Aligning an annular cutter
While performing the adjustments, please note that the annular cutters are very sharp
and you can suffer physical injuries easily.
1) Set the cutter holder at 90 degrees;
Photo 6
2) Place the Euroboor HSS annular cutter in the cutter holder. Don’t tight the Hex screw yet. It
is important to hang the Hex screw on the round side of the cutter shank (photo 6);

10
3) Switch on the laser beam with the red button on top of the laser beam housing
4) Turn the annular cutter with the hand and place the flat teeth in one line with the 90
degrees line of the cutter holder. It is easy to do this precise with the laser (photo 7);
5) If the flat teeth is in one line, tight the annular cutter with the Hex screw;
Photo 7
6) Direct the laser beam with the help of the laser guidance rod to align it above one of the flat
teeth.
7) Rotate the core drill in the holder until the laser beam only just touches the tip of the
selected tooth.
8) Mark the first aligned tooth
SPECIAL NOTE:
While adjusting the annular cutter in the holder, please ensure that the wheel screw is not in contact
with a flat position of the Weldon shank of the cutter. To prevent the slightest of unintended
movement of the cutter the wheel screw must lie on the rounding of the cutter shank.

5.3.2 Grinding stretched surfaces
First is the grinding surface of the flat teeth. Not the market one, two teeth further. Set the column
scale (photo 9) to °5. Set the cutter holder scale (photo 10) to °14. Every time make two clicks
further, for the next tooth to grind.
Photo 9
Photo 10
After the flat tooth, grind the outer side of the V-shape tooth. Set the column scale to 7.5°. Set the
cutter holder scale to 20°. Every time make two clicks further, for the next tooth to grind.
After de reshaping the Outer V-Shape next tooth to grind V-Shape inner side. Set the column scale to
20°. Set the cutter holder scale to 5°.
SPECIAL NOTE
The value of this setting is not the same for all annular cutters.
1) Move the annular cutter along the grinding disk in stationary condition, and if necessary,
correct the angular setting (the angular setting can be in the 15 to 30 degree range).
2) After making the angular adjustments, bring the annular cutter with the guide carriage and
motor feed near the grinding disk. Grind the stretched surface with the radial diamond disk
provided for the purpose. Do not grind the tooth that was aligned (marked tooth). Instead,
grind the next stretched surface below it.

13
3) Move the annular cutter along the grinding disk in stationary condition until the stretched
surface touches the diamond disk. Set the lateral stop and the fine tuner in such a way that
the stretched surface can be ground.
4) Now grind the stretched surface set by you. Feed through the fine tuner should be low, and
it should be uniform for all the stretched surfaces. After grinding the first stretched surface,
pull the guidance carriage back and turn the knob in the clockwise direction (direction of
arrow) right up to the next section. You can position the next stretched surface in this
manner. Do not alter the motor feed and the fine tuner position. Repeat the grinding
process till all the stretched surfaces have been ground.
5.4 Replacing the grinding disk
Always pull the plug out of the mains socket before replacing the grinding disk. No core
drill should be in the holder while replacing the grinding disk.
