Abstract:
The invention provides a method and apparatus relating to fluid cutting in which a cutting jet of fluid is directed through a nozzle (2) on a jet path, the jet path passing through a cutting zone in which a work piece (10) is placed in use and subsequently to a baffle area (6), the baffle area providing a baffle element which deflects the jet from the jet path on to a deflected path, the atmospheric pressure being greater in the area of the cutting jet path prior to deflection than in the area of the jet on the deflected path. In this way, the invention provides for reduced generation of spray or aerosols and/or assists in containing and removing such spray and/or aerosols from the air.
Abstract:
A cutting tool device for a machine tool having a cutting tool (2) for cutting a plane fixed to the tip end of a rotating shaft (1) and provided with a suction cover (10) covering airtightly the surrounding portions, except for a tip face (a), of the cutting tool (2), wherein a hood (19) is attached to the tip opening edge of the suction cover (10) so as to further extend forward therefrom and to be displaceable longitudinally within a limited range, and an urging means (24) for urging the hood (19) forward is provided, whereby chips (w1) produced by the cutting tool (2) can be positively sucked and discharged when the tool is used in any of a roughing step and a finishing step.
Abstract:
To improve chip extraction, and in particular the removal of chips remaining in the mortised groove, a mortising machine having a dust-extraction device (10) with a suction opening (11) surrounding the cutting tool comprises a second suction opening (25) which can be applied to the workpiece (7) in the region of the mortised groove (8) during operation. A deformable object, in particular a brush (28), penetrates the groove (8) and restrains the chips at the exit from the groove (8). The chips are removed by the section connection pieces (18) and the connecting sleeve (17) for a suction tube. The section device is suitable for all types of mortising machines, in particular recessing and shaping machines.

In this way, the invention provides for reduced generation of spray or aerosols and/or assists in containing and removing such spray and/or aerosols from the air.
Abstract:
Apparatus for collecting swarf from a machine tool operation such as a vertical milling cutter (1) is formed from a chamber (5) substantially surrounding the milling cutter and pneumatic conveying means having a nozzle (13) arranged to suck swarf from the chamber. The chamber is provided with a flexible skirt (12) having at least a distal portion that is generally frusto-conical in shape which deforms on contact with the workpiece (4) providing partial sealing to the chamber and enhancing the pneumatic conveying of swarf from the chamber without risk of contact with the machine tool.
Abstract:
The present invention relates to a method and a device in the chip-removing machining of a work-piece (3) by means of a rotatable tool (4) with an arbor arranged in a headstock. The tool (4) is displaceable both in an axial direction towards and away from the work-piece (3) and in a plane substantially perpendicular to the arbor. Arranged around a machining point (2) is an enclosure (1), which has a first opening (6), designed to bear tightly against the work-piece (3) around the machining point (2). A second opening (9) in the enclosure (1) is made in a wall (8) substantially perpendicular to the arbor and is designed, during machining, to bear tightly against a plane plate (10) arranged behind the tool (4) and around the headstock, substantially perpendicular to the arbor, so that during machining there is a substantially enclosed space in the area around the tool (4) and the machining point (2). The device comprises means of delivering cutting fluid to the machining point (2) and the enclosure (1) has an outlet opening (12) through which chips that are removed are evacuated from the enclosure (1) by means of the cutting fluid delivered.
Abstract:
Eine Splitterschutzvorrichtung für eine Holzbearbeitungsmaschine weist eine Streifenmatte (8) aus einem flexiblen reißfesten Material auf, wobei die Streifenmatte (8) über wenigstens zwei Lagen (39) mit einer Anzahl von Streifenfingern (42) verfügt und wobei die Streifenfinger (42) benachbarter Lagen (39) seitlich gegeneinander versetzt sind. Dadurch wird ein im wesentlichen spaltfreies und damit betriebssicheres Umschließen eines Massivholzkörpers (24) sowie ein Abdecken von Fallenfingern erzielt.
Abstract:
The present invention relates to a method and a device in the chip-removing machining of a work-piece (4) by means of at least one tool (2) capable of rotating with an arbor arranged in a headstock, which tool is displaceable in an axial direction towards and away from the work-piece (4). An enclosure (1) is arranged surrounding the tool (2), which enclosure is open towards the work-piece (4) around a machining point (6) associated with each tool (2). The enclosure (1) is designed to bear tightly against the work-piece (4) around the machining points (6). An opening (8) accomodating each tool (2) is designed, during machining, to bear tightly against the headstock or the arbor of each tool, so that there is a substantially enclosed space in the area around the tool (2) and the machining points (6). The device comprises means for the optional delivery of cutting fluid to the machining points (6), and the enclosure (1) has an outlet opening (10) intended for the evacuation from the enclosure (1) of chips that are removed and any cutting fluid delivered.
Abstract:
A recovery system (10) is disclosed for recovering a treating material (12) for treating a surface (20) with a vacuum source (25). The treating material (12) may be a cleaning material such as sand, water or may be a coating material such as a paint or a plasma coating. The apparatus (10) comprises a housing (16) having a housing opening (18) for projecting the treating material (12) from a nozzle (14) through the housing opening (18) onto the surface (20). A fluid seal means (30) provides a seal between the housing (16) and the surface (20). The vacuum source (25) is connected to the housing (16) for withdrawing the treating non-adhering material (12A) from the housing (16).
