Tech Tips for Micro Tools

1. Handle micro end mills with the utmost care so not to damage or break the tool.
2. Use only non-contact measurement systems such as a laser or non-contact tool presetter when measuring the end mill diameter and setting tool lengths.
3. Cleanliness and good housekeeping practices are paramount when assembling micro end mills in tool holders.
4. Clean tool holder to machine spindle mating surfaces before inserting a tool holder in the machine spindle.
5. Use high precision tool holder technology such as shrink fit. Shrink fit technology offers excellent rigidity, repeatability, and low T.I.R. Low T.I.R. is important to maintain a consistent load on the cutting edges.
6. Rule of thumb for calculating acceptable T.I.R. in inches is to multiply the end mill cutting diameter by .002
7. With the end mill in the tool holder measure the tool holder assembly balance. Balance should be grade G2.5 or better.
