The power tool includes a housing, a motor mounted in the housing and operatively connected to a tool holder arranged to hold a cutting tool bit, at least one guide post slidably mounted to the housing such that the housing is moveable between a retracted position and a plunged position, a base portion fixed to the guide post, and a height adjustment mechanism. The height adjustment mechanism includes a threaded sleeve fixed with respect to one of the guide post or the housing and an adjustment sleeve threadedly engaged with the threaded sleeve. The adjustment sleeve includes a housing stop portion configured to engage the other of the housing or the guide post in the retracted position. Movement of the adjustment sleeve with respect to the threaded sleeve is configured to adjust the distance between the housing and the base portion when the housing is in the retracted position.

The present invention relates to a transport device (100) for transporting one or more handling devices, each for handling a pallet (300) and/or a workpiece (1) on a machine tool (1000) which is set up on a base surface for machining the workpiece (1), wherein the transport device (100) is freely movable on the base surface for positioning the one or more handling devices relative to the machine tool (1000), in particular within a region in front and/or next to the machine tool (1000) and/or in front and/or next to a working space of the machine tool (1000).

A flushing duct is installed on both sides of a table of the machine tool in a longitudinal direction of the table, a slope duct is inclinedly disposed below the flushing duct toward the coolant tank, each bottom surface of the flushing duct and the slope duct is formed with a V-shaped inclined surface and a streamlined bending portion to make flows of the coolant containing the microchips smooth, and a coolant supply valve is installed at a rear end of the flushing duct to facilitate flows of the coolant being discharged by supplying additional coolant. Further, a coolant tank is installed below the slope duct, a filter is installed in the coolant tank for filtering the microchips in the coolant. The coolant containing the microchips is transported through a return pump to a centrifugal separator device where the microchips contained in the coolant are centrifugally separated. A refined coolant through centrifugal separation is supplied to the machine tool, thereby preventing abnormal wear due to penetration of the microchips into rotating and sliding portions of the machine tool.

Several problems may result from finished parts falling to the bottom of a CNC machine as each part is completed. For example, the finished parts are mixed with scrap shavings and machine coolant and must be manually separated from the scrap shavings. The manual separation process exposes an operator to the scrap shavings and the machine coolant. This problem is emphasized when the finished part is particularly small or delicate. Specifically, small, finished parts may be more difficult to manually distinguish from the scrap shavings. The presently disclosed small parts catcher is intended to be a simple, low-cost device, attachable to a CNC lathe turret, particularly to a cut-off tool, to catch small parts as they are severed from a workpiece.

A work-machine splash guard for enclosing a space for machining a workpiece, and preventing the spraying of chips and machining fluid, is equipped with: a front-surface door for opening and closing in the horizontal direction via an arc-shaped movement, and positioned on the front-surface side of the work machine; a side-surface door for opening and closing by performing an arc-shaped movement that is concentric with the front-surface door, and overlapping with the front-surface door; and door-locking switches for selectively allowing the opening/closing of the front-surface door and the side-surface door according to an opening/closing pattern.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.

The present invention relates to a chip collecting box for a machine tool and, more specifically, to a chip collecting box, in which bottom plates that open and close by means of hinges are installed on opposite sides at the bottom of a chip collecting box body having open upper and lower portions. When an opening cord is pulling while the chip collecting box body is in an upwardly raised state, the bottom plates on opposite sides become unlocked and open toward the bottom such that machine tool chips stored in the chip collecting box are discharged downward. When a closing cord is pulling after the chips are discharged, the bottom plates on opposite sides are closed by the closing cord and become hooked on a hooking means.

A filter unit is connected between a tray and a discharging duct of a spiral conveyor. The filter unit includes a first filter (perforated metal) that is fixed at a position close to the outer periphery of a conveying spiral, and a second filter (mesh filter) that rotates on the outside of the conveying spiral and the first filter. A washing nozzle sprays a washing liquid on the second filter. The chips captured by the first filter are scraped by the rotating conveying spiral and delivered back to the conveying path and the chips passing through the first filter but captured by the second filter are removed by the washing nozzle and delivered back to the conveying path. The washing liquid is sprayed at a predetermined angle from the washing nozzle and collides with vanes arranged on the outer periphery of the second filter and provides rotational force on the second filter.

The present disclosure relates to systems, devices, and methods for reclaiming cutting fluid used in a machining operation. In particular, in some embodiments, the disclosed systems include a fluid container for collecting a cutting fluid used in a machining operation. Additionally, in some implementations, the disclosed systems include a sensor for detecting a fluid level of the cutting fluid within the fluid container. Moreover, in some embodiments, the disclosed systems include an actuator and a hose assembly for moving cutting fluid from the fluid container toward a reservoir of a machine tool. Furthermore, in some implementations, the disclosed systems include a controller for initiating the actuator upon sensing that the fluid level of the cutting fluid exceeds a predetermined threshold level.

Provided is a chip collection apparatus that enables efficient chip discharge, overcomes troubles caused by chip buildup, and enables elimination of maintenance such as cleaning work. A chip collection apparatus includes a belt conveyor that transports chips to a chip discharge part, a conveyor frame designed to cause a bottom plate located below the belt conveyor to receive chips that have fallen from the belt conveyor, and a washing mechanism that ejects washing fluid for discharging chips to outside the conveyor frame. The bottom plate of the conveyor frame has such a shape in transverse cross section that the bottom plate is deeper toward the center. The washing mechanism has a bottom-plate washing nozzle that ejects the washing fluid such that chips received on the bottom plate are directed toward the chip discharge part.
