2.13 Cutting Blocks
A trueing (filing) of the cutting block becomes necessary,
–
when the cutting block has been too strongly cut into by the cutting knife.
–
when two different cutting knife forms have worked on the cutting block (Illus. 2).
When trueing the cutting block care is to be taken:
–
The cutting block must be so filed that the impression of the knife blade is to
be seen everywhere very fine and exactly uniform ( Illus. 1).
–
The height of the cutting blocks may only be reduced by a maximum 1.5 mm
through filing.
–
To achieve a uniform distribution of the cutting pressure the cutting block must hit
parallel onto the cutting knife (see sketch).
One-sided cutting pressure, particularly in the area of the eye, can cause the
cutting knife to break off.
Illustration 1 shows a correctly filed, illustration 3 a badly filed cutting block.
–
After trueing one cutting block, all other cutting block used must also be reworked
to the same height dimension. Only in this way can, after a cutting block change,
work continue with the same cutting pressure. Otherwise there is a danger of
breaking the cutting knife by a change of the cutting block !
Malfunctions during cutting
After a longer period of operation the sharpness of the cutting knife is reduced. The
blade is blunt and the knife no longer cuts precisely in spite of a correctly trued cutting
block.
–
Send the knife to one of the DÜRKOPP ADLER AG for reworking.
Caution Risk of Injury !
Pull the mains plug.
Remove the cutting block only with the machine turned off.
ATTENTION !
The trueing of the cutting block must be conducted very
precisely.
Use only flawless, straight bastard files !
