Description
The Vicmarc CBN Sharpening Station is another ground-breaking innovation from
Vicmarc Machinery. The 1HP (0.75kW), fan-cooled slow speed grinder runs at
1450RPM and comes with 2 X 200mm CBN wheels of your choice (80, 180, or
240 grit). With both wheels mounted on the same side of the shaft, the space-
saving footprint of this system is unlike any other on the market.
Important: when grinding V10 or any other High Speed Steel tools you must
make sure that the tool doesn’t get too hot and change colour (brown or blue) as
this will weaken the steel and shorten the life of your tool. You should
periodically dip the tip of the tool in water when it begins to get warm but before
it gets hot.
Safety Information
1. Read and understand this instruction manual before operating the Grinding
System.
2. Always wear eye protection.
3. Do not wear neckties, jewellery or loose clothing.
4. Do not operate without guards in place.
5. Tighten all handles before operating.
6. Make sure the grinder is off and has stopped rotating before making any
adjustments.
7. Do not operate while under the influence of drugs, alcohol or medication.
8. Some of the guards in this manual have been removed for photographic
purposes. Always use the guards as supplied and specified with your
grinder.
Please note: the following setting up instructions are a guide only. Personal
grinding setting can be achieved by adjusting the positions and angles to suit
your own preferences.

Setting up the Station and CBN wheels
1. Slide your CBN wheels onto the grinder shaft making sure that the bushes
are in their correct position.
2. Tighten CBN wheels
3. Line up the rest platform so that the centre of the rest plates is in line with the
centre of the CBN wheels ensuring that the gap on either side of the wheel and
front face is equal and then tighten the M8 knob. See Picture below.
Page 5
4. Tighten down the motor to the base and the motor base to the station base.
See below.
5. Check again that the CBN wheels are square and centred to the grinding
rest.
6. Your setup is complete and you can begin sharpening

Setting up your Grinding Rest
Use the Grinding
Rest to grind this
angle
1. To initially shape the top angle of the bowl gouge, place the Vicmarc Quick
Tool Setter so that both radii contact the grinding wheel as shown below.
2. Then adjust the Grinding Rest to meet flush with the bottom of the Vicmarc
Quick Tool Setter as shown below. Lock the table and the bottom slide in
place. Make sure that the table does not touch the wheel. There should be
approximately 2mm clearance between the wheel and the rest.

The Grinding Rest Quick Tool Setter can
be used to set and grind other popular
angles (22, 33, 44& 66).
To set the desired angle, place the
Grinding Rest tool setter with numbers
facing the right hand side & the text flat
on the Grinding Rest. Both radii should
be touching the wheel & the rest must be
positioned as close to the wheel as
possible. If the rest is too far away from
the wheel the angle may vary. The
diagram to the left shows how to set 66

3. Place your gouge upside down on the rest and grind the top of the tool away
until it meets the bottom of the flute. This pre-grind makes your tool look
like the profile below.
4. Important: Make sure that the tool does not get too hot and change
colour (brown or blue) as this will reduce the hardness of the metal and
shorten the life of the tool. To prevent this, make sure you periodically dip
the tool in water. If you find the tool heating up too quickly then you may
need to re-dress your wheel or apply less pressure on the grinding wheel.

The triangle slide gauge has some pre-set angles to enable you to grind precise
angles as shown below.
23/37.545/90
Skew Chisels - 23
Set the rest to 33and then use
the provided gauge as a guide.
To sharpen simply hold the tool
against the gauge and slide it
back and forth over the wheel.
Straight Edge Scraper - 66
Use the 90gauge and rest the scraper
along the edge. Move the scraper from
left to right to grind the front angle of
the scraper.
Parting Tools - 33& 44
Set the rest to 33or 44and
then place the chisel against the
rest. To sharpen simply slide
the 90gauge along the tool
slide.
Roughing Gouge & Round End
Scraper - 66
Set the rest to 66then rotate the
roughing gouge or pivot the round end
scraper on the rest to grind the bevel.
You can also use the V-gauge provided

Setting up your Sharpening Jig
1. To set-up for a 55grind, place the Vicmarc Quick Tool Setter into the
pivoting point. Then slide the slide plate out so that the two radii on the
gauge (on the 55angle side) both touch the grinding wheel. Then lock the
slide plate into position.

2. Place your bowl gouge into the Sharpening Jig and set it to protrude 55mm
by using the Depth Gauge as shown below. Lock the gouge into position
by tightening the black knob.
Page 10
3. Line up the angle on the Sharpening Jig to the 55mark as shown below.
This is done by holding the jig locating bar and the gouge, and manually
adjusting the angle.
Note: Do not loosen the nuts and bolts for this adjustment.

4. Place the Sharpening Jig in the pivoting point and swivel from side to side
until you have roughed out the bevel profile and removed most of the
material. Rotate the Jig constantly from right to left to avoid flat spots and
overheating
5. Important: Make sure that the tool does not get too hot and change
colour (brown or blue) as this will reduce the hardness of the metal and
shorten the life of the tool. To prevent this, make sure you periodically dip
the tool in water. If you find the tool heating up too quickly then you may
need to re-dress your wheel or apply less pressure on the grinding wheel.
