Abstract: A machine tool for machining a workpiece clamped in the working space of the machine tool by means of a tool. The machine tool includes a machine bed, which has a chip collection region having at least one conveying channel open on the working space side for collecting chips that drop during the machining of the workpiece, and a conveying device for leading away chips that have dropped into the chip collection region in the at least one conveying channel. The conveying device has a stationary supporting shaft, which extends in the at least one conveying channel in the longitudinal direction of the conveying channel, wherein a spiral element is rotatably supported on the stationary supporting shaft, and wherein the conveying device also comprises a drive for driving the rotational motion of the spiral element about the stationary supporting shaft.

Abstract: A device for treating cooling lubricants and chips of machine tools. The device includes a container for receiving the untreated mixture of cooling lubricant liquid and solids, an endless conveyor installed in the container for carrying off the collected solids from the container, at least one filtration unit disposed in the container for separating the cooling lubricant liquid from the solids, whereby the filtration unit is formed so as to be mobile and can be positioned as an insertion in the container over the lower run of the endless conveyor.
