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 cutting speed (Vc) can be calculated from the outer diameter (Dc) and rotational speed (min⁻¹) of the tool.
Formula for calculating cutting speed (Vc)
Vc: Cutting speed π: Pi 3.14 dc: Tool diameter N: Rotational speed
When to use cutting speed (Vc)
By using the cutting speed (Vc), it is possible to calculate the rotation speed (min⁻¹) of a size that is not listed in the condition table of the catalog.
・ The cutting speed (Vc) that has been successfully processed can be expanded to different sizes.
Both ▲A φ20 drills and ▲B φ10 drills are A, Vc ⇒ 6.28m/min B, Vc ⇒ 3.14m/min Even at the same 100 revolutions, the distance the cutting edge moves is different. |
