A metal chip conveyor having an internal chip removal structure includes an endless conveyor belt. An accommodating room of a machine body is divided into an inner space and an outer space. Two sides of the conveyor belt are provided with chains each having chain links. Each chain link has a first opening facing the inner space and a second opening facing the outer space. Two support bushes are disposed at opposite sides of the casing. The conveyor belt passes around the support bushes and is supported by the support bushes. The support bushes cover the first openings of the chain links corresponding in position to the support bushes when the conveyor belt is running, thereby preventing the metal chips in the chain links from falling back into the inner space through the first openings and ensuring that the metal chips in the inner space to be discharged stably.

A dust-collecting plant of a circular sawing machine is combined with a circular sawing machine, which contains a machine base and a working platform. The dust-collecting plant includes an upper fundamental seat, a slide seat and a lower fundamental seat. The upper fundamental seat is provided with plural slide rods inserted out of the slide seat, which has one side provided with a transmission unit containing a saw blade and another side disposed with a dust-collecting plant containing an accommodating groove and a dust-collecting mouth. The lower fundamental seat is fixed at another end of the slide rods and provided with a lifting unit for moving the slide seat up and down. When the slide seat is moved up and down, the saw blade and the dust-collecting mouth can maintain equidistance, letting scraps sawed eject directly to the dust-collecting mouth for enhancing efficiency of dust collection.

A method of forming a compact includes removing material from a workpiece, transferring metallic dust released during the material removal into a conduit, operating a plurality of slide gates to selectively control movement of the dust from the conduit to either one of a primary collector and a back-up collector, drawing the dust through the conduit to a compactor, and compacting the dust in the compactor.

Provided is a device discharging chips, which is configured to allow smooth transfer because it is possible to absorb transformation of connecting pins due to a force generated while chain driven belts are operating as well as smoothly discharging a coolant and chips.

A pump having a cutting wheel (20) and a pre-cutter (26) driven by a shaft portion (24) that projects axially from the cutting wheel (20) and has a plurality of wings (28) that extend radially from the shaft portion (24), wherein the wings (28) differ in their axial arrangement on the shaft portion (24).

An apparatus for collecting dust from a cutting unit is provided. The apparatus includes a rotary valve operatively connected to the cutting unit, a conduit in fluid communication with the rotary valve, and a compacting machine disposed downstream from the conduit and configured to receive dust from the conduit. A blower is configured to pull air downstream to carry the dust into the compacting machine. The compacting machine produces a compact from the dust.

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.

A machine tool including a machining device configured to perform machining on a workpiece in a machining chamber, a chip conveyor including a reservoir tank into which machining chips generated by workpiece machining in the machining device flow, together with a coolant, the chip conveyor being configured to discharge the machining chips to an outside of the machine tool, a coolant tank in which the chip conveyor is incorporated, the coolant tank being configured to accumulate the coolant flowing out of the reservoir tank, a sub-tank provided to surround an outer side of a discharge window for the coolant, the discharge window being formed on a side surface of the reservoir tank, and a machining chip removal section in which a magnetic separator made of a magnet is accommodated in the sub-tank and an opening portion configured to filter the coolant is provided around the magnetic separator.

A machining system including a base; multiple work modules arranged in an arrangement direction on the base, at least one of the multiple work modules being a processing module, which processes a work with a tool, provided with a main shaft head including a main shaft on which a tool is attached and a main shaft rotating device that rotates the main shaft; a head raising and lowering device that moves the main shaft head in a vertical direction; a head moving device that moves the main shaft head in a horizontal plane by moving it in two perpendicular directions; and a work table that holds a work; the processing module being configured so as to be pulled from the base along a path extending in an intersecting direction, which is a direction perpendicular to the arrangement direction.
