and Badger Knives
When grinding moulder and planer knives, factors such as grinding wheel types and grit are often a matter of personal preference. A grinder operator may be able to get the same results using different abrasives by altering the RPM of the wheel and the rate of feed. There are, however, some important guidelines that should be followed in order to guarantee the safest and best operation.
Always be sure to read the operation instructions for your grinder as well as any information from the manufacturer of your abrasives and grinding wheels. Be sure to observe all safety instructions with regard to protective devices and proper ventilation.
Whether you choose to grind using a single wheel, or rough grind with a coarse wheel followed up with a finish grind, the knife bevel that you maintain will play an important role in your success.
Generally, a 35 degree bevel will give the best results for most planing or moulding applications using High Speed steels or Karbo Krome. See illustration.
Grinding OPTI® Knives
Never grind or hone the face on Opti knives as this may remove
the ultra hard surface of the knife. A better finish will be obtained
on Opti knives if the grinding wheel RPM is increased by 500 RPM
for the rough and finish grind.
