For milling and indexable tools, the following three numbers are required:
(1) Rotation speed (min-1)
How many revolutions per minute .
In NC code, it is expressed by "S". Example: 300 revolutions per minute = S300
(2) Feed speed Vf(mm/min)
What does cutting speed mean?
Cutting speed is the speed at which the outermost part of the tool moves in one minute.
Symbols are denoted by Vc. The unit is (m/min).
The feed rate is the number of millimeters that the tool moves in one minute.
The unit of feed velocity (Vf) of the drill is (mm/min).
The feed rate can be calculated by multiplying the rotation speed listed in the catalog by the feed amount.
The feed amount is the distance of how many millimeters the tool has traveled in
Rotational speed means how many revolutions the tool makes in one minute.
In the machining program that moves the machine tool, it is expressed by "S". In calculations, "n" may also be used. The unit is (min⁻¹). Example: S2000 → 2000 revolutions in 1 minute
The expression of the speed of rotation is different from t
Cutting Data Table Meaning of Numbers "Speed of Rotation" and "Speed of Movement"
When machining by machine, it is necessary to set specific figures.
In the case of rotary tools such as drills, Tap ,
It can be calculated using the following calculation method.
Vf (feed rate) = fz (feed amount per blade) × z( number of flutes ) × n (rotational speed)
number of flutes : Please check from the specifications of your indexable cutter or end mill.
Rotation speed (n): It can be calculated from the
The catalog condition table is an efficiency-oriented condition.
If you value more stable machining and tool life, we recommend the following adjustments.
・ Check the cutting conditions (rotation speed) of drills and taps from the bottom of the condition range in the catalog.
The amount of feed per rotation of the drill (mm/rev) is likely to affect the shape of the
