1. MACHINE DESCRIPTION AND INSTALLATION
1.1 Machine description ( FIG. 1.1 – FIG. 1.2 – FIG. 1.3- FIG. 1.4 – FIG. 1.5 )
This sharpener has been designed to simply and effectively solve the problem of sharpening knives and
scissors .
It consists of a aluminium structure (5) , a painted steel basement (15) containing the electric system and a
front paitend steel structure (14) containing the wheels (1-2-3 ) . The control button and the emergency stop (
22-21 ) are placed on the basement (15) on the left side (FIG. 1.3) . On the back of the basement (15) there
is a cable with a socket for the power supply .
The structure (5) supports 3 C40 steel shafts (7) placed horizontally and supported by 6 bearings (18). Two
helicoidal C.B.N.-coated wheels are placed on the 2 central shafts in order to sharpen knives ( 1-2 ). A
cylindrical C.B.N.-coated wheel is mounted on the right shaft to sharpen scissors (3) .The wheel-holding
shafts are moved by a system consisting of 4 toothed pulleys ( 8-10-12 ) and a double toothing belt ( 17 ) ,
placed in the basement (15).
The knives sharpening wheels (1-2) are penetrating and form a constant angle. The knives sharpening
wheels turn upwards opposing each other so that they are opposed to the edge of the blade to be
sharpened .The scissors sharpening wheel (3) turns anticlokwise. On the structure is mounted a reference
inclined surface for scissors sharpening ( 4 ) ( FIG. 1.2 ).
A connection to insert the vacuum cleaner tube is mounted on the right side of the front structure (14).
The machine can be provided by a system ( Optional ) that allows to keep the blade of the knife in the right
position during the sharpening operation ( Right Position System ) ( FIG. 1.5 ) .
The machine was designed and constructed to sharpen only metal knives ans scissors . The
sharpening of any other cutting and/or working tool is forbidden.
The following blades can be sharpened: knives : flat blades with straight or convex edge ;
scissors : flat blades and straight edge .
The following blades cannot be sharpened: deformed or non-flat blades, broken or splintered blades,
blades with concave edge, hook-shaped blades, too long and thick blades (max. thickness 4 mm,
max. length 400 mm) , serrated blades , blades with hardness < 50 Hrc , cleavers , heavy butcher
knives , half heavy butcher knives .

SHARPENING ( FIG. 3.3 – 3.4 – 3.5 – 3.6 – 3.7 – 3.8 – 3.9 )
Carry out the following operations to obtain a satisfactory result :
Blades with straight and smooth edge (Figure 3.3 – 3.4 ):
1.
2.
3.
4.
5.
6.
take the knive by the handle and place the blade parallelly to the horizontal surface keeping the tip
foreward;
approach the blade to the middle of the helicoidal wheels and keep it as straight as possible;
move the blade backward and foreward three times or more pressing it slightly .
remove the knive by lifting it;
check the obtained result ;
repeat the operation until obtaining the required edge.
WARNING : Light pressure works best , let the grinding wheels do its job . Extra pressure will
reduce the wheels and knife life . Extra pressure may cause a machine block .
Blades with convex and smooth edge (Figure 3.5 – 3.6):
1.
2.
3.
4.
5.
6.
take the knife by the handle and place the blade with a slope of about 10 degrees with respect to the
horizontal surface and keep the tip foreward ;
approach the blade to the middle of the helicoidal wheels without damaging the tip. Keep the tip as
straight as possible ;
move the blade backward and foreward three times or more pressing it slightly. Follow the blade
profile avoiding a too steep slope of the knive and pay attention not to damage the tip;
remove the knive by lifting it ;
check the obtained result by vertically cutting a piece of paper ;
repeat the operation until obtaining the required edge.
WARNING : Light pressure works best , let the grinding wheels do its job . Extra pressure will
reduce the wheels and knife life . Extra pressure may cause a machine block .
Right Position System ( R.P.S. ) ( Optional ) ( FIG. 3.9 )
The R.P.S. allows to keep the blade of the knife in the right position during the sharpening operation . The
sharpening operation should be done in the same way as explained leaning the reference of the R.P.S. on
the back side of the blade . In this case the free hand can be leaned on the top part of the R.P.S. , but
without any pressing . During the sharpening operation the R.P.S. will follow the movement .

After sharpening the knive it is advisable to remove the featheredge by running the edge on both sides on a
fine grain sharpening steel. The blade should form an angle of max. 20 degrees with respect to the
sharpening steel axis.
WARNING : At the end of the downward movement the blade tip should be moved away form
the sharpening steel so that it does not touch the handle in order to avoid dangers.
Take the sharpening steel vertically with one hand. With the other hand seize the knive handle and lay the
blade on the sharpening steel tip without exceeding the suggested 20 degree angle. Slide the blade on the
sharpening steel along the edge performing an arched movement.
It is of great importance that the sharpening steel has a very fine grain. The commonly used sharpening
steels are not suitable for this operation.
We suggest the use of the ceramic-coated sharpening steel produced by our company (art. FR300-300) .

Operations and personnel in charge
WHEEL REPLACEMENT (FIG. 4.1)
When the wheel efficiency decreases the wheel metal becomes visible or the sharpened blade is overheated.
In this case it is necessary to replace the wheels.
WARNING : use only wheels supplied by the manufacturer , the removed wheels should be
disposed of as scrap and not in the environment .
Wheel disassembly:

remove the screws from the machine front side (14);
insert a 7/8 mm diameter pin into the 10 mm hole on the helicoidal wheel (1). The pin should be
inserted into the hole on the alluminium structure;
unloose the eight M6 socket head screws of the wheel fixing system (16) ;
repeat the same operation on the fixing system of the wheel (2) ;
mantaining the pin into the wheel (2) it is possible unloose the eight M6 socket head screw of the
fixing system of the wheel (3) ;
remove the two helicoidal wheels from the shafts.
Wheel assembly:
WARNING : Before assembling check the status of the new wheels , if damage has occorred
on the wheel profiles the wheels should be changed . Otherwise metal part splitting can occur .
WARNING : The wheel marked with D/R must be mounted on the right side shaft , the wheel
marked with S/L must be mounted on the left side shaft , the profile of the wheels will move in the
opposite direction of the operator . Wrong assembling the profile will move towards the operator
creating a dangerous situation , approacing the sharpening with the tip the knife could be ejected .
Clean the wheels housing and lubricate the shafts before the wheels assembly . Check that both
parts (7) are in correct position .

place the two helicoidal wheels (1-2) on the shaft . The wheel screws should fit one into the other.
ATTENTION : The wheel marked with D/R must be mounted on the right side shaft , the wheel
marked with S/L must be mounted on the left side shaft ;
insert the 7/8 mm pin into the 10 mm hole on the helicoidal wheel (1). The pin should be inserted into
the hole on the alluminium structure;
the wheel (1) should be fixed correctly; simultaneously tighten the 8 socket head screws of
the wheel fixing system pushing the pulley and keeping the wheel against the shaft end ;
when fixed it must be any movement to the shaft direction ;
remove the 7/8 mm pin and insert it into the helicoidal wheel (2). Turn the fixed wheel (1) so that the
screw crest of one wheel is in the middle of the other screw. It is very important to avoid any contact
between the screws. Repeat the same operations did before ( see point 3) ;
mantaining the pin into the wheel (2) it is possible loose the eight socket head screw of the fixing
system of the wheel (3) ;
remove the 7/8 mm pin from the wheel (2) ;
check the rotation of the wheels manually , any contact should be between the wheels ;
assemble the front structure (14) and the basement (15).
