Re-tipping of cutting plates is only allowed by specialists who are experienced in brazing
and who can assess the influence of the brazing process concerning the tensions in the
body and the cutting material.
When debrazing damaged tips and afterwards brazing new tips, it shall be ensured, that
the cutting elements are correctly fastened and that critical tension won’t be created in the
body due to the brazing process.
The design of composite tools (e.g. tools with brazed tips) is not allowed to be changed at
the servicing.
Tool labellings, which have been affected by modification / re-tipping, have to be updated.
Name/ logo of the modifying / re-tipping company have to be added.
1.6.2 Sharpening
TC-tipped circular sawblades principally should be resharpened from the cutting area on
and from the clearance face on in order to optimally use the tooth.
When resharpening the clearance faces reduce the tool body diameter to maintain the
tooth height.
Grinding only the cutting area reduces the number of possible resharpenings.
DP-tipped circular sawblades exclusively are sharpened on the clearance face.
For safety reasons circular sawblades with a tooth height less then 1 mm have to be
scraped.
Ask the tool manufacturer for the sharpening instruction.
