Abstract
A cutting device includes an accommodation chamber having a through hole, a cover plate covering the accommodation chamber, and a cutting unit carrying a cutting element that is partially submerged in a cooling fluid in the accommodation chamber. A liquid level display is provided in fluid communication with the through hole in the accommodation chamber for indicating the level of the cooling fluid so that a user can conveniently ascertain in real time, from outside the cutting device, the current amount of the cooling fluid retained within the accommodation chamber and can add cooling fluid to the accommodation chamber as needed in real time, thus achieving improved performance in cooling and lubricating the cutting element.
