Milling Cutter Usage Precautions:

1. Before using the cutter, please check the cutter's runout. If the runout accuracy exceeds 0.01MM, please correct it before cutting;

2. The shorter the projection of the cutter from the chuck, the better. If the projection is long, it is necessary to reduce the spindle speed, feed rate, or cutting depth;

3. In case of abnormal vibrations or noise during cutting, please lower the spindle speed and feed rate until the situation improves;

4. For cooling of steel materials, spray or jet cooling methods are preferred, which can effectively enhance the milling cutter's performance and lifespan.
