A radius e. g of 5mm is to be ground. To do this, the tool must be moved by 5mm to the
front and 5mm to the side. Using the micrometer screw a 5mm traverse is to be adjusted.
After that, the clamp of the clamping plate is to be loosened and shifted forward by the set
value.

Adjusting the radius:
In order to move the tool by 5mm to the side, the cross table is shifted with the assistance
of the micrometer screw. To do this, the clamp of the upper slide is to be loosened at first.
A 5mm traverse means turning the micrometer screw by 10 revolutions. After that, the
clamp of the upper slide is to be tightened again.

Adjusting the clearance angle:
Before starting to grind the radius, the clearance angle of e. g. 10 degrees must be
adjusted.

Figure 13-6: Adjusting the clearance angle
Turning angle:
With the assistance of the stoppers and the two scales, the turning angle around the
rotational axis is to be adjusted, for example, if the tool must have a corner angle of 70
degrees. For this, a turning angle of 110 degrees must be adjusted. Scale 1 is to be set to
10 degrees and scale 2 is to be set to 110 degrees.
Figure 13-7: Turning angle
Handling:
After everything has been adjusted, you can start to grind the radius. For this, the tool
must be brought into contact with the grinding wheel. It is advisable to open the central
clamp of the universal swivel holder and to move the entire swivel holder to the correct
position. Only in this case the infeed is done by the fine adjustment.

Figure 13-8: Grinding the radius
Grinding the radius:
The radius is created by swivelling the tool around the rotational axis. With the assistance
of the stopper A for the tilting movement, the position is to be set in which a continuous
rolling of the radius on the grinding wheel can be carried out. After every complete swivel
movement, in this case e. g. 110 degrees, infeed is carried out by means of the fine
adjustment and the grinding process is repeated.
SM-1-03/02
Figure 13-9: Grinding the radius
Another method to grind the radius is to separate the rotary movement and the infeed.
Clamping is carried out in the initial swivel position and a larger material fraction is ground
off. After that, the material removal process is repeated with a new turning angle . This is
continued until the entire turning angle area is covered. After that the radius grinding is
finished in one go.

Grinding the radius
Figure 13-10: Grinding the radius
To check the gound radius the entire clamping plate can be removed from the swivel
holder. The dimension of the radius is measured under a profile projector. Using the
micrometer screws on the cross table and/or on the clamping plate, the correction value
can be set and the grinding of the radius can be finished. Different grinding wheels can be
used for pre-grinding or finishing the grinding.
Halving the cutter:
At first set the graduated scale to 0 degrees. Then clamp the cutter and align it ny means
of the centering bracket. Set both turning angle scales to 0 degrees, set the stoppers and
clamp them against a rotary movement. Set the clearance angle scale to 0 degree. Bring
the cross table of the swivel holder into the central position (the surface must be flush) so
that the rotary axes of the dividing apparatus and the swivel holder intersect.
Figure 14-1: Halving the cutter
Set the dividing apparatus to 90 degrees. Make the contact to the grinding wheel. Adjust
the stopper for maximum insertion depth and start the grinding process with fine infeed.
By moving the swivel holder back and forth, material is removed by the grinding wheel.
Continue fine infeed until the cutter has been halved.

Grinding the cutter:
After the cutter has been halved, the dividing apparatus has to be reset to the 0 degree
position. Now the actual cutter grinding can be started.
Figure 14-3: Grinding the cutter
Setting the turning angle:
You want to have a cutter with e. g. a structural tip shape with an angle of 60 degrees.
For this the scale 1 must be set to 30 degrees and the 2 stoppers must be clamped.
SM-1-03/02
Figure 14-4: Setting the turning angle
Setting the turning angle:
You want to have, for example, a cutter with a face cutting edge or a conical structure
shape, then the turning angle must also be set in the other direction. This stopper can e,
g, be set to 93 degrees. This corresponds to a clearance angle of 3 degrees at the face
cutting edge.

Setting the clearance angle:
Before grinding can be started, the cutting angle of the cutter must be set. The cutting
angle depends on the material e. g. between 15 and 25 degrees.

Grinding the cutter:
Clamp the turning angle at 30 degrees. Adjust the stopper for the insertion depth. After
that, make contact to the grinding wheel and start the grinding process. Remove material
by means of fine infeed during which time the swivel holder is to be moved back and
forth.

Figure 14-8: Grinding the cutter
Handling:
The picture figures the procedure of grinding a cutter with a pointed structural shape. It is
advisable to hold the dividing apparatus with both hands in order to carry out the grinding
process. The left hand carries out the back and forth movement for grinding while the
right hand carries out the rotary movement.

Grinding the cutter relief:
The grinding of a relief of a milling cutter is carried out by uniformly turning the collet
chuck over the entire rotary range and infeed by the fine adjustment screw of the swivel
holder. This automatically carries out relief grinding.
Figure 14-10: Grinding the cutter relief
SM-1-03/02
When the grinding of the relief has been finished make sure that, when the dividing
apparatus turns back, the cutting edge of the milling cutter is not damaged. This could
happen if the dividing apparatus is turned too far. The scale of the dividing apparatus
indicates the current position.

Milling cutter:
Almost all optional shapes of milling and engraving cutters can be produced. Cylindrical,
pointed or conical structural shapes, front and side cutting edges as well as rounded
shapes can be easily and quickly ground. The quick change unit for the grinding wheel
offers the possibility of being able to use the optimal grinding wheel for every case of
application.
The coolant pump and the coolant tank are integrated into the base of the machine. Only
emulsions based on water may be used. The coolant system may not be operated with
flammable liquids under any circumstances. The tank must be pulled out of the base for
the purpose of checking the level. The maximum filling quantity amounts to approx. 7
liters. The coolant pump is electrically connected in the way that it can only be started
together with the grinding spindle.
A splash guard which is located beneath the pan can be attached to the edge of the pan
and offers the operator protection during wet grinding.
Figure 15-1: Coolant unit
A flexible plastic hose serves as the supply line for the cooling liquid. A ball-type spigot
serves to regulate the coolant flow and to shutt off the line. There are drain holes in the
machine pan which are connected to the coolant tank via a return line.
