인서트의 외경이 드릴 몸통부위 보다 최소0.3mm(0.012)이상 커야 함. RPM = Revolution per minute (rev/min)
Check that the insert outer diameter is a minimum 0.3mm(0.012″) M/mm = Surface meter per minute (M/min)
larger than the holder body diameter. DIA = Diameter of drill (mm)
mm/rev = Feed rate (mm/rev)

상기표의 추천 Speed와 Feed는 이상적인 조건이며 장비의 상태와 작업

38 여건에 따라 Speed와 Feed는 줄여서 작업을 하십시오. Holder Extended Long XL 3XL
“The recommendations for speeds, feeds and other parameters Speed 0.90 0.85 0.80 0.75
Feed - 0.95 0.90 0.90
presented in this chart are nominal recommendations and shold

be condidered only as good starting points.”

초기 작업시 Speed는 약20%, Feed는 약10%줄여서 자업조건을 설정

하시기를 바랍니다. Recommended Speed and Feed Example :
“If recommended speed and feeed is 30M/min and 0.50mm/rev
When initial operation, speed and feed reductions (20% reduction
for a standard length holder, then the speed and feed using a
in speed and 10% reduction in feed)are recommended. 3XL holder in the sam application would be 22.5M/min and
0.45mm/rev”
Formulas = (RPM)×(π)×(DIA)
1000 ex)30×0.75 = 22.5m/min, 0.50×0.90 = 0.45mm/rev

mm/min = (RPM)×(mm/rev)

RPM = 3.1415×(M/min)
