The blades should be ground in a special grinder to achieve the correct cutting edge and
accurate centring of the rotor shaft.
Correct grinding and adjustment of the Multicutter or granulator is necessary in order to
achieve a satisfactory result and a long working life (Please study the grinding instructions
below).
Cutting and grinding Theory
Reconditioning your cutter as specified in these instructions will restore its orginal precise
cutting capability.
The cutter works on a rotary cutting principle. Material is cut at the interface between a
fixed bed knife and rotor-mounted knives to provide two or six cuts for each complete rota-
tion of the rotor.

FIG.1
Knife Clearance
True cutting requires the clearance between the rotor and bed knives be less than the
thickness of the material being cut.
The resharpening and knife setting methods result in knife clearances down to 0.0064 mm/
0.00025 in (0.0127 mm/0.0005 in for MC 5000) with no knife contact. Cutters set to this
clearance will cut all types of thin films.
Very close clearances also provide longer useful knife life. The closer the starting clea-
rance, the longer will be the operating time before the knives wear to the point they will no
longer cut.
The rotor knives of the model MC cutters or granulators are at a shear angle. This reduces
both the cutting force and the operating noise level.
