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.

Chatter Vibrations in MicroMilling Due to the fragile nature of the miniature tools, even a minute vibration in micromilling can lead to part failures. Similar to macro operations, micromilling processes also exhibit an unstable phenomenon, called regenerative chatter, due to the undulations on a previously cut surface (34).
