Measures to eliminate machining faults of end mill

Fault
Occurrence situation
Measures
The machined
surface is not good
The surface is smooth, but there
are concaves and convexes
¡ñReduce feed.

¡ñIf it is double-flute, change it to 4-flute.
Chips are short and thin,
but there are sticky chips.
¡ñ Increase cutting speed.

¡ñUse wet or compressed air (increase flow)

¡ñMake miniature rounding passivation treatment.

¡ñChange from conventional milling to climb milling.

¡ñ Increase feed or cutting allowance.
There are cross cutting marks
¡ñMake miniature rounding passivation treatment.

¡ñUse non-water soluble cutting fluid.

¡ñChange from climb milling to conventional milling
There are excess cutting
marks left.
¡ñReduce cutting allowance.

¡ñIncrease cutting speed.

¡ñReduce feed.
Profile precision
is not good.
The size of finish machining
is smaller.
¡ñ Change from conventional milling to climb milling.

¡ñReduce cutting allowance.

¡ñReplace chuck or spring collet.

¡ñReduce overhanging volume of end mill.

¡ñIncrease cutting speed
Square trowel is not good.
¡ñReduce cutting allowance.

¡ñReplace chuck or spring collet

¡ñReduce overhanging volume of end mill.

¡ñIncrease cutting speed.

¡ñChange from double-flute to 4-flute.

¡ñReduce feed.

¡ñCheck wear, replace tools.
Vibrating
 
¡ñIncrease feed (reduce if more than 0.04mm/tooth)

¡ñTry changing cutting speed.

¡ñReplace chuck or spring collet.

¡ñReduce overhanging volume of end mill.

¡ñRough milling uses double-flute, finish milling uses 4-flute.

¡ñChange from climb milling to conventional milling.
