Abstract
Abstract A chips-deoiling machine, which is characterized in that a group of separators consisting of a number of single separators being spaced controllably in equal intervals in relation to the neighboring separators, which group of separators is provided within a carrying passage through which chips thrown into a chips-charging port are carried toward a chips-discharging port with the aid of the rotation of a screw shaft, and that the cutting oil contained in said chips is separated through the respective gaps between said single separators in the process of said chips passing from one side of the interior of said group of separators toward the other side.
