Spindle Speed Calculator

Formula

To calculate the spindle speed (\(SS\)):

\[ SS = \frac{CS}{\pi \cdot D} \]

Where:

\(SS\) is the spindle speed in rotations per time
\(CS\) is the cutting speed
\(D\) is the diameter

What is Spindle Speed?

Spindle speed is the rotational speed of a spindle, typically measured in rotations per unit time. It is calculated by dividing the cutting speed by the product of pi and the diameter of the spindle.

Example Calculation 1

Let's assume the following values:

Cutting Speed (\(CS\)) = 100 m/min
Diameter (\(D\)) = 10 mm

Using the formula:

\[ SS = \frac{100}{\pi \cdot 10} \approx 3.18 \text{ rotations per minute} \]

The spindle speed is approximately 3.18 rotations per minute.

Example Calculation 2

Let's assume the following values:

Cutting Speed (\(CS\)) = 200 m/min
Diameter (\(D\)) = 20 mm

Using the formula:

\[ SS = \frac{200}{\pi \cdot 20} \approx 3.18 \text{ rotations per minute} \]

The spindle speed is approximately 3.18 rotations per minute.
