Trouble Occurrences of trouble Countermeasures
•Surface is good but rough 1. Decrease feed
2. In case using 2 flute, increase to 4 flute
•Small chip welding 1. Increase cutting speed TOOL HOLDERS
2. Utilize wet cutting air blow(ample supply) TOOL HOLDERS
3. Carry out fine honing
4. Up cut → Down cut
Inferior finished surface 5. Increase feed or enlarge finish allowance
•With transverse streaks 1. Carry out fine honing
2. Use water insoluble cutting fluid
3. Down cut → Up cut
