How many speeds are available in when using stepped cone pulley drive in a lathe?

A stepped cone pulley drive in a lathe typically offers multiple speeds, commonly ranging from 3 to 12 different speed settings, depending on the design and number of steps on the pulley. The variation in speed is achieved by shifting the belt onto different diameters of the pulley, allowing for a range of rotational speeds for the spindle. This flexibility enables the operator to select the appropriate speed for various machining operations.
