Design and Function
Grinding wheel
Knives, which are precisely positioned using the grinding arm [4]
or [5], are ground on the rotating grinding wheel. The cooling water
supply [1] provides cooling water. The guard ring [7] secures the
grinding wheel against inadvertent contact with the user and prevents water splashing.
Wet grinding belt
Knives are ground and deburred on the wet grinding belt [8]. The
grinding belt is guided over rollers and automatically tensioned.
The position of the grinding belt can be adjusted. The cooling water
flows through a channel from the tray below the grinding wheel to
the wet grinding belt. A marker shows the grinding belt's direction
of rotation. The belt safety guard [9] prevents access to the grinding belt during operation. The grinding and honing machine does
not start if the belt safety guard is not mounted.
Polishing wheel
Ground knives are deburred and polished on the polishing wheel
[17]. A marker shows the polishing wheel's direction of rotation.
6
Grinding angle device
The lift rod, scale head [19] and grinding angle display make up the
grinding angle device [18]. The grinding angle device is altered
vertically with a motor. The foot pedal controls the motor. The
grinding angle device can also be moved horizontally after loosening the clamping lever on the left-hand side of the machine. The
grinding angle device accommodates the grinding arm, which positions the knives over the grinding wheel. The vertical movement of
the grinding angle device changes the grinding angle.
Grinding arm
The grinding arm [4] is available in two different versions. Round
cutting edges can be sharpened with the radial grinding arm and
round and straight cutting edges with the universal grinding arm.
Grinding plates for clamping the knives are mounted on the mounting head [3] The grinding plate and double grinding lever [2] are
fastened here with the star handle.
SM-200 TE Grinding and Honing Machine 23
Page 24
Design and Function
6
The double grinding lever with the grinding plate is rotated into the
grinding lever support [21] on the back when workpieces are not
being machined. The grinding plate is mounted and the knives are
inserted here.
Cooling water unit
The grinding wheel and grinding belt are water-cooled. The cooling
water unit [11] provides the cooling water. The cooling water unit
on the SM-200 TE grinding and honing machine with a stand is
housed in the stand [15], otherwise it is provided. The cooling
water unit has a pump and the power is supplied indirectly via a
connection to the grinding and honing machine. A water tank contains the cooling water. The cooling water is fed to the grinding
wheel via the cooling water supply and runs off into the tray. The
cooling water is fed through a cooling water channel to the grinding
belt. The cooling water accumulates in the belt safety tank and is
fed back to the water tank through a drain and hose.
Grinding device holder
Position the UB3F or UB3F-XL belt grinding device (special accessory) on the mountings for the belt grinding device [12] on the front.
This accommodates the grinding plates that can be used to precisely
grind machine knives, such as cutter blades, on the grinding belt.
Dressing tool
Dress the grinding wheel if it is dirty or uneven. The bolt [20] next
to the grinding wheel holds the dressing tool for the grinding wheel
in place.
Mains plug
The power is supplied via the mains plug [10]. The pump of the
cooling water unit is powered by the SM-200 TE grinding and honing machine.

The control panel [16] contains the main On/Off switch [1] for the
SM-200 TE grinding and honing machine and one On/Off switch
each for the cooling water [3] and the abrasives [2], the grinding
wheel, wet grinding belt and polishing wheel.
Foot pedal
Adjust the grinding angle with the foot pedal [14]. The motor moves
the grinding angle device [18] vertically to do this. This changes

The contoured cutting edge is produced after grinding the cutting
angle. Grind three bevels for basic sharpening. The following bevel
stages are tried and tested: 17°, 13° and 9°. These grinding stages
are marked in red on the scale of the grinding device.
The grinding of bevels is similar to the V-shaped edge. However,
a burr is only formed on the cutting edge when grinding the angle
of the cutting edge.
Round the bevels in the next step on the grinding stone or on the
wet grinding belt.
Grinding the angle of the cutting edge:
1 Set the grinding angle on the grinding device to 27°.
2 Lift the workpiece off the grinding wheel with the double grind-
ing lever.
3 On/Off switch for the abrasives to position I (ON).
4 Set the On/Off switch for the cooling water to position I (ON).
5 Lower the workpiece with the double grinding lever. Move the
area to be ground back and forth over the grinding wheel with
light pressure.
NOTE
Do not stop the movement of the workpiece on the grinding
wheel.
• There is a risk that the knife will overheat and the contour will
be damaged if the workpiece remains stationary on the grinding wheel.

Machining Workpieces
NOTE
• Follow the instructions of the knife manufacturer for grinding
workpieces.
6 Repeatedly raise the workpiece and check the progress of the
grinding.
7 Complete the process when a burr has formed on the cutting
edge.
Grinding the bevels:
1 Lift the workpiece off the grinding wheel with the double grind-
ing lever.
2 Set the grinding angle on the grinding device to 17°.
3 Lower the workpiece with the double grinding lever. Move the
area to be ground back and forth over the grinding wheel with
light pressure.
4 Complete the process once a smooth bevel has formed.
5 Repeatedly raise the workpiece and check the progress of the
grinding.
6 Repeat this step for the other bevels with the grinding angles
of 13° and 9°.
7 The bevelled cutting edge profile is pregrounded.
The bevels must be rounded in the next step. This is done on the
grinding stone or wet grinding belt.
Rounding on the grinding wheel:
Round the edges of the bevels by constantly changing the grinding
angle. Never set the grinding angle at a more obtuse angle than
the angle of the cutting edge or 25°.
1 Lower the workpiece onto the rotating grinding wheel with the
double grinding lever.
2 Constantly move the grinding arm on the grinding device up
and down between 20° and 5°, thus changing the grinding
angle. The grinding angle must not be at a more obtuse angle
than the angle of the cutting edge.
3 Lift the workpiece off the grinding wheel with the double grind-
ing lever.

4 Check that a smooth surface has formed without edges.
5 Complete the process when a smooth bevelled contour has
formed on the surface.
6 Place the double grinding arm in the support facing backwards.
7 Take the knife out of the grinding plate.
8 Check the ground knife with the grinding template provided by
the knife manufacturer.
Rounding on a wet grinding belt
• Follow the instructions in chapter 9.7 “Grinding hand knives
and cleavers” for working with the wet grinding belt.
1 Place the double grinding lever in the support facing backwards.
2 Take the workpiece out of the grinding plate.
3 Grind the contoured surfaces on the wet grinding belt.
Constantly change the grinding angle.
4 The grinding angle must not be at a more obtuse angle than
the angle of the cutting edge. If the grinding angle gets closer
to the angle of the cutting edge, the grinding noise changes
slightly and the pressure of the water jet drops. Then switch to
a steeper grinding angle.
5 Complete the process when a smooth bevelled contour has
formed on the surface.
NOTE
9.5 Deburring and polishing machine knives
Deburr and polish the machine knives after sharpening. Use the
polishing wheel to do this.
WARNING
Risk of injury. Guide the knives by hand when deburring and
polishing. The knives are always sharp and can cause cuts.
• Never place knives against the cutting edge on the polishing
wheel.
• Wear cut-resistant gloves.
• Never grip the cutting edge.
• The workpiece can become hot.
SM-200 TE Grinding and Honing Machine
52
Page 53
Machining Workpieces
NOTE
The fins of the polishing wheel must not get wet.
Moisture damages the lamellar buffing wheel and makes it unusable.
Holding and guiding the knife
Hold and guide the knife by hand when polishing and deburring.
• Hold the knife close to the body.
• One hand holds the workpiece in such a way that it can be
polished safely on both sides by turning the hand. There is no
change to the grip on the workpiece during this process.
• The other hand changes the position when the workpiece is
rotated. It supports the other hand in guiding the workpiece.
The hand is placed on top of the workpiece in each case and
exerts the required pressure for the polishing. The cutting
edge of the knife is parallel to the polishing wheel shaft. The
surface to be polished is tangential to the polishing wheel
and at an obtuse angle to the previous bevel.
Applying polishing compound
Apply polishing compound to the lamellar buffing wheel for the polishing.
1 Press the block of polishing compound against the polishing
wheel while it is running.
• Apply the polishing compound shortly before starting up the
polishing wheel and using it to avoid contamination caused
by flying particles of compound.
• Repeat the process if the polishing effect wears off or the polishing compound is no longer present.
Deburring knives
Polish the ground cutting edge alternately on both sides for the
deburring.
1 Hold the workpiece in the hands and guide it onto the polish-
ing wheel.
2 Guide the knife over the polishing wheel.

3 Rotate the workpiece so that both sides of the cutting edge
are machined evenly.
4 Hold the workpiece at a steep angle and under considerable
pressure on the polishing wheel at the beginning.
5 Repeatedly check the condition of the burr.
6 If a burr is no longer visible, guide the workpiece 3-4 times in
a flat position over the polishing wheel while applying pressure. This will polish the cutting edge.
Polishing the surface
1 The hands take their positions on the knife.
2 Guide the knife back and forth from side to side over the pol-
ishing wheel.
3 Exert only a little pressure.
• Prepare the ground surface by pregrinding it on the wet grinding belt to reduce the polishing time.
9.6 Sharpening circular blades
NOTE
WARNING
Circular blades have a sharp cutting edge around the circumference. They could cause serious injuries.
• Wear cut-resistant gloves when working with circular blades.
• Work with due care and attention.
Specific preparations are needed depending on the diameter of the
circular blade. Information regarding the steps are provided in
chapter “8.11 Setting up special solutions for circular blades”,
page 45.
Start sharpening the circular blades if all preparations have been
completed.
1 Lift the circular blade off the grinding wheel with the holder.
2 Press the I (ON) button on the main On/Off switch.
3 Move the grinding angle on the grinding device to 25° or to the
grinding angle specified by the manufacturer.

Machining Workpieces
4 Set the On/Off switch for the abrasives to position I (ON).
5 Set the On/Off switch for the cooling water to position I (ON).
6 Lower the circular blade onto the grinding wheel and apply
light pressure.
The circular blade immediately rotates automatically as a result of
the relative movement to the rotating grinding wheel. If this does
not happen, lift the circular blade again immediately and adjust the
settings.
7 Continue sharpening until a burr has formed on the circumfer-
ence of the blade.
8 Repeat the grinding on the other side on circular blades with
a symmetrical bevel. To do this, remove the circular blade
from the special clamping device, rotate it and mount it again.
Deburr the circular blade after sharpening it.
9 Lower the grinding arm slightly. Place the circular blade on the
grinding wheel while applying very little pressure to the grinding lever. The circular blade rotates. Remove the burr by alternately placing a sharpening steel on both sides of the cutting
edge at an angle of 15°-20°.
