Information on the grinding wheels
The machine is designed for using grinding wheels with
150
mm
diameter, 20 mm thickness
and
12,7
mm center
-
bore, suitable for material being worked on
.
Only use wheels which have a marked rotation
speed equal to or greater than 2850 /min.
Protect the wheels from blows, crushes, as well as oil.
Mounting the grinder on a workbench
It is highly recommended
that you bolt this bench grinder securely to a
workbench to gain maximum
stability for your machine.
•
Using the base of the grinder as a template, mark the
bench through the holes
(
16
)
in the
casting.
•
Drill the holes and bolt the bench grinder to the
bench with bolts, washers and nuts
(not supplied).
•
To reduce vibration, mount the
bench grinder
on a vibration
absorbing mat.
Installing the tool rests
•
Fix the tool rest
(
12
)
to the grinder with washer and
thumb screw (
13
).
Repeat for the other side.
•
Adjust each tool rest frequently to compensate for wear of the grinding wheel. Keep the distance not
more than 2 mm.
•
Ensure that the tool rest is firmly
fixed and horizontal.
•
One of the tool rests
has an angled grove to allow you to sharpen the drill bits.
Installing the spark deflectors
•
Fit both spark deflectors
(
2, 10
)
to the
grinder
using washers and screws
(
9
)
.
•
Adjust each spark deflector
frequently to compensate for
wear of the grinding wheel
.
Keep the
distance not more than 2 mm.
Installing the eye shields
•
Attach right
eye shield arm
(
8
)
to
the bench grinder using bracket
(
7
), flat washer
and screw (
6
)
.
•
Fit the lens
with holder
(
11
)
to the arm
(
8
).
•
Repeat for
the
left
side eye shield.
•
Adjust the eye shields to an
appropriate distance from the
tool rests to avoid
interference during
operation.
•
One of the eye shields has a magnifier lens.
Dressing the grinding wheel
When the grinding wheels start to become clogged with debris, use the dresser tool
(
5
) to clean and
renew (dress) their working surface.
•
Start the machine and let the wheels reach their full rotation speed.
•
Place the dresser tool (
5
) on the tool rest with the dresser wheels facing the
grinding wheel.
•
Slide the dresser tool forward until contact is made with the grinding wheel
and maintain a light
pressure to clean the debris from the grinding
wheel.
•
After dressing, adjust the tool rests and spark deflectors to keep the clearance at no more than 2
mm
from the wheel face.
Replacing the grinding wheel (Fig.
B)
Replace the grinding wheel as soon as its residual material
thickness
does not allow keeping
a safe
clearance (maximum of 2
mm) between the wheel face and the spark deflector or the tool rest
.
•
Loosen the screws (
18
) and
rotate and remove the wheel cover
(
17
)
.
