Guide for Helical milling

For helical milling, use between Min. cutting dia. and Max. cutting dia. Exceeding Max. Cutting Dia. Under Min. Cutting Dia.

DescriptionMin. Cutting Dia. Max. Cutting Dia.For helical milling, use between Min. cutting dia. and Max. cutting dia. Keep machine depth (h) per rotation less than
max. ap (S) in the cutter dimensions chart. Use caution to eliminate incidences caused by producing long chips.

Recommended cutting conditions

It is recommended to reduce feed by 25% of recommendation until the center core is removed when traversing after drilling. Axial feed rate recommendation per revolution is f < 0.1mm/rev.

The number in bold font is recommended starting conditions. Adjust the cutting speed and the feed rate : 1st recommendation : 2nd recommendation within the above conditions according to the actual machining situation. Cutting with coolant is recommended for ni-base heat resistant alloy and titanium alloy. Cutting with coolant is recommended to get good finished surface.
