  • Patent number: 10335980
    Abstract: A dust suction drill includes: a drill tip with cutting edge portions; a shaft joined to the drill tip and configured to rotate about an axis; and a dust suction passage that is generated when the cutting edge portions rotate, the dust suction passage being formed inside the shaft. The cutting edge portions are provided on a distal end surface of the drill tip and spaced apart from each other in a circumferential direction. Cutting edges, each of which is formed by a joint ridge between a rake face and a relief face of a corresponding one of the cutting edge portions, are arranged radially, and at a center of the drill tip, form a chisel point, which is a pointed end. A dust suction hole, which communicates with the dust suction passage, is formed in the rake face or the relief face closely to the chisel point.

  • Patent number: 10183339
    Abstract: A depth limiting device for a drill includes a main body, an axial braking structure, and a limited shrinking structure. The axial braking structure is attached to the main body. The limited shrinking structure surrounds a drill rod of the drill, is slidably attached to the main body, and is in a home position or a compressed position. The axial braking structure axially brakes the drill rod such that the drill rod moves together with the depth limiting device. When the drill rod enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the drill rod from entering further into the subject.

    Abstract: The present invention relates to a chamfer device for machining a weld bead surface, which specifically carries out a chamfering process on the welding bead surfaces of objects to be processed (such as metal sheet materials and pipes). In the present invention, immediately after a chamfering-amount-adjustment unit has been rotated and released, a position-setting pin is inserted into a securing recess in the chamfering-amount-adjustment unit, while the chamfering amount is adjusted in precise units and simultaneously locked at a predetermined chamfering amount which is automatically maintained, and the adjustment of the chamfering amount is achieved in a straightforward fashion with just one touch. When the chamfering-amount-adjustment unit is operated, a mobile cutter shaft moves vertically and as it does so the chamfering amount is adjusted in such a way that the chamfering amount can be immediately and rapidly adjusted while continuously operating without regard to any cutter rotation action.

    Abstract: A drill countersinking and seal groove machining tool to accommodate an accurate drill countersinking and seal groove machining operation. The linear compensator tool applies sufficient force to react to the drilling or seal groove machining process, but not so much force as to distort the work piece being drilled or machined. The tool ensures that the reactant force does not exceed the machine force override allowances. Varying spring rates and/or air pressures on the linear compensator system will accommodate most applications. The tool absorbs over travel of the machining tool, in order to ensure that the surface to be machined is always in contact with the machining tool.

  • Patent number: 7607871
    Abstract: A floating tool-bit depth controlling nosepiece for a spring loaded tool holder is used to countersink holes of equal size when the height of the work piece material changes. The floating tool-bit depth controlling nosepiece, driven by a cnc machine, is rigidly coupled to the floating portion of the tool holding element. The floating depth controlling nosepiece has a bearing on the end to allow an area of the nosepiece to stop rotating when the nosepiece is pressed against the work-piece surface. Since the area of the nosepiece that comes into contact with the work-piece is no longer spinning in relationship with the work-piece, the possibility of scratching the work-piece surface is reduced. Additionally, the nosepiece has cutouts therein to expel machined chips during countersinking of holes.

  • Patent number: 7513722
    Abstract: A stop for a drill bit having a shaft, the stop having a first member which includes a collet. The collet is configured to receive the shaft of the drill bit and is positionable along the shaft of the drill bit. The stop also has a second member which includes a clamp, for clamping the first member in a desired position along the shaft of the drill bit by securing the collet in a desired position along the shaft of the drill bit. The stop further has an abutment surface on one of the first and second members, for limiting the depth of penetration of the drill bit into an object, the abutment surface being disposed in a fixed position along the shaft of the drill bit by the clamping of the first and second members.

  • Patent number: 7507058
    Abstract: A tool positioning device and a machining element have simple structures which can reduce running cost. In addition to a hole that engages with a shank of an end mill, a channel is provided so that it penetrates through the device such that one end thereof communicates with an upper face of the device and the other end communicates with a lower end of the device. In this case, it is more effective to provide a concave portion that is opened to the upper face and communicates with the hole. The same effect may be obtained by making a cylindrical hole, for example, instead of the channel.

  • Publication number: 20090010726
    Abstract: A machining method for machining a superficial portion of a laminate using machine tool having a depth limiter which restricts a maximum depth of the machine tool. A guide frame having an inner guide contour restricts a maximum dimension of the superficial portion, and is secured over the superficial portion. The superficial portion is machined while the machine tool is guided by the guide contour. From another point of view, a machining apparatus for machining a superficial portion of a material is provided. The machining apparatus comprises a guide frame, an inner guide contour for guiding a machine tool, an attachment member for securing the guide frame to an attachment member, adjacent to the superficial portion, of the material.

  • Publication number: 20080247833
    Abstract: A countersinking-carrier nozzle has a flat front surface with a central hole via which emerges a countersinking drill, such that said flat front surface establishes a limit to the penetration depth of the countersinking nozzle. The nozzle includes a flexible retainer for the nozzle front surface so that it swivels when making contact with a curved countersinking surface, adapting itself tangentially to it while the headstock presses against the countersinking surface. The flexible retainer is defined by a ball-and-socket joint including a curvo-concave retaining receptacle, with the possibility of swivelling, with a complementary curvo-convex portion provided in the rear part of the flat front surface. This portion projects with respect to the receptacle to allow it to swivel when pressed against the countersinking surface, at which moment the complementary curvo-convex portion of the rear part of the front surface swivels in the receptacle of the headstock.

  • Patent number: 7261499
    Abstract: An adjustable drill microstop apparatus is employed with a drill and a drill bit to limit the depth of a hole drilled into an object surface by the drill bit. The apparatus has a housing and a nose piece that is mounted for reciprocating axial movement in accordance with a plurality of user selectable depths of cut. The nose piece projects from one end of the housing and is positioned adjacent the object surface to receive the drilled hole. The nose piece has an opening into which the drill bit is inserted, and an engagement surface that engages with the object surface during the drilling operation. During the drilling operation, the drill pushes the nose piece into the housing as the drill bit performs the drilling operation. A pre-selected distance that the nose piece reciprocates in the housing limits the depth of the hole drilled by the drill bit into the object surface.
