Here are a few thoughts of where to look for problems when you're breaking small cutters: 1. Start By Attacking Runout. Inexpensive machines typically have more spindle runout than higherend CNC's. Runout is a real problem when micromilling because you should think of runout as a % of the cutter's diameter.
