■ Cutting Conditions Calculation Formula
Center Drilling
CTDA / CTDAL / TA-CTDA / TA-CTDAL / TA-CTDACW / TA-CTDAR
TA-CTDA, TA-CTDAL, TA-CTDACW, and TA-CTDAR can process with cutting speed increased by about 20 to 50%.
NC Spot Drills
NCSPD / G-NCSPD / TA-NCSPD / TA-LS-NCSPD / TC-HNCSPD
G-NCSPD, TA-NCSPD, TA-LS-NCSPD, and TC-HNCSPD can process with cutting speed increased by about 20 to 50%.
For TA-LS-NCSPD, use with feed amount lowered by about 20 to 30%.
Countersinks
Model Number
G-CS3M / TA-CS3M / TA-LS-CS3M / TA-CS1M / TA-CSHM
TA-CS3M, TA-LS-CS3M, TA-CS1M, and TA-CSHM can process with cutting speed increased by about 20 to 30%.
When machining aluminum alloy, TA-CS1M and TA-CSHM can process with cutting speed increased further by about 20 to 30%.
