 Recommended grain  sizes:

• B126, B151 for sharpening.
• B181, B252 for correcting the profile of saw teeth or for profiling if necessary.

The advantages of using galvanic borazon grinding wheels include:

-Very long lifespan and sharpening efficiency.
-No need for truing the wheel, as required with ceramic grinding wheels.
-No deformation of the saw teeth during the sharpening process.
-Reduction in sharpening costs.

Usage guidelines:

The optimal peripheral speed  for these grinding wheels (20-30 m/s) is crucial for sharpening efficiency and wheel longevity.

Recommended types of cooling oil:

-ACP-2-E non-emulsifying – ORLEN
-WECO EP-10 (or EP-15) – PROMASZ

 

Notes:
It is not recommended to use oil-water emulsions due to the sensitivity of borazon grain to water. In low ambient temperatures, it is advisable to heat the machine oil to reduce its viscosity. During the sharpening process, the coolant stream should be directed directly at the grinding wheel (not at the saw teeth) to remove metal swarf promptly and prevent clogging of the working surface. The flow of cooling oil must be continuous. Periodically, it is recommended to clean the grinding wheel with motor oil.
Before starting the sharpening process, check the alignment of the grinding wheel with respect to the saw blade. The grinding wheel profile should contact the working part of the saw (tooth) along its entire length, only reaching the bottom of the saw’s gullet. The grinding wheel profile must be adjusted to match the profile of the teeth of the saw being sharpened. Tooth shapes may vary depending on the manufacturer and the type of wood being processed.
