Break-in procedure: For long blade life
-
For extended blade life, less blade changes and
best payback of your tool cost, special break-in procedures
should be adhered to.
-
Overload of the razor-sharp tooth tips should be
avoided at the start of cutting operation. Aggressive
cutting with new blades will lead to premature tooth breakage.
-
Correct break-in will control the gentle rounding
of the cutting edges.
-
Starting feed should be half of the final feed
rate at the recommended cutting speed for the first 150 - 200 cm2
cut surface. After that, feed rate should be gradually increased
for maximum cutting rate as mentioned above.
