Abstract: The invention relates to a deburring tool for deburring abutting edges at orthogonally and obliquely extending transversal boreholes having a diameter of less than 10 mm in a component, such as an engine block, an injection system for combustion engines, a valve block and a camshaft or transmission shaft. The deburring tool is moved in a rotational and/or translatory manner and comprises a tool shaft (1), which is provided with a clamping end (2), and a tubular shaft part (5), characterized in that said tubular shaft part holds one or several cutting bodies (11) with a cutting blade (3), the cutting bodies being mounted in a movable manner in a passage (10), and in that a substance that is pressed under pressure into the through-bore (7) of the tool shaft (1) displaces the blade(s) to the exterior. The deburring tool is configured as a single piece and can be produced at low cost. Different blade geometries remove the burr by means of high speed deburring.

Abstract: The invention pertains to a deburring tool for deburring the interior and/or exterior of work pieces, for example, abutting edges on intersecting bores or on longitudinal and transverse grooves in bores or on transverse bores in a deep-hole bore with different diameters of an engine block, tubular work piece ends, edges on and in flat work piece surfaces or surfaces of a toothed wheel or a sprocket wheel. The deburring tool can be used in machine tools and is pressure-controlled. The cutting forces can be variably adapted to the burr dimensions that change during the machining process and to different materials. Corresponding embodiments of the deburring tool ensure the deburring of different work pieces with a good quality and in a short period of time. The inventive deburring tool is particularly advantageous in that it can be used in intermittent assembly lines with the latest manufacturing technologies.

Abstract: Adjustment system for positioning a cutting insert on a cutting tool has a rotatable first rod with a surface having a plurality of flatted areas arranged radially, each at a different radial distance from an axial center of the first rod relative to a sequentially adjacent flatted area, a translatable second rod with an axially tapered surface, wherein a face of the first end of the second rod contacts one of the plurality of flatted areas, a biasing element positioned to exert a force to bias the face of the first end of the second rod to contact the flatted area, and a translatable push pin, wherein a face of the first end of the push pin contacts the tapered surface and wherein a face of the second end of the push pin operatively contacts a cartridge mounted on the cutting tool and in which the cutting insert is seated.

Abstract: An adjustable cartridge to be mounted in a boring bar, the cartridge including an anvil rotatably affixed to said boring bar, said anvil including a pocket into which a lay-down indexable insert is affixed. The anvil is secured in an axially oriented slot which includes an arcuate seating face. Rotation of the anvil within the slot effects radial adjustment of the insert.

Abstract: A cutting tool is described which comprises at least one exchangeable cutting blade mounted on a parallellepiped cutting blade holder which in turn is adapted to be fixed by a setscrew at a tool body. The setscrew passes through the cutting blade holder such that the holder is pressed flat against a first recess surface and, at the same time, in the direction of a second recess surface extending at an angle with respect to the first one, the setscrew penetrating the cutting blade holder with clearance for freely adjustable fastening such that it includes an angle of substantially the same size with both recess surfaces and presses the cutting blade holder against the second recess surface by two adjustable support members of which at least one is designed as a rotatable eccentric pin the axis of which extends substantially parallel to the associated second recess surface and which is supported in a fitting recess of the cutting blade holder or of the tool body.

Abstract: A boring bar is disclosed having an elongated body adapted to be rotatably driven around a predetermined axis. A longitudinally extending bore is open to at least one end of the body and has an axis which intersects the body axis at an acute angle. A cutting tool has an elongated shank with a cutting edge at one end while the other end of the shank is slidably received within the bore so that the radial displacement of the cutting edge with respect to the cutting axis is directly proportional to the longitudinal position of the shank within the body bore. A nut threadably secured to the body engages a radially extending pin secured to the shank in order to adjust the longitudinal position of the shank within the bore.

Abstract: A boring head (10; 50) for internal machining of bores in workpieces comprising an insert holder (16; 41) and an operating means (18; 27; 51, 52) resting thereagainst. The operating means is adapted to adjust the insert holder (16; 41) radially when turned about its longitudinal axis. The boring head (10; 50) is associated with control means (21; 28; 63), which are adapted to turn the operating means (18; 27; 51, 52). To advantage the boring head might be provided with a cutting insert, the cutting edge of which comprises a straight forward portion (68) and a convex rear portion (69).

Abstract: An adjustable insert cartridge is described in which a toolholder shank is threadedly engaged in a threaded adjusting sleeve having a flange with a rearwardly facing face. The rearwardly facing face is in rotatable sliding engagement with a forwardly facing face on a mounting collar which is attached to a boring bar. The rearwardly and forwardly facing faces are held in abutment by a spring which is compressed between a rear face of the mounting collar and an adjusting ring threadedly engaged on the adjusting sleeve.

Abstract: The present invention relates to a boring device for boring internal surfaces of hollow workpieces of the kind which comprises radially adjustable insert-provided holders, there being provided pressure means, such as steering pins so as to effect radial adjustment of the insert holder from an outer active working position to an inactive position. The radial adjustment occurs by having each insert holder via said steering pins supported against a bushing of non-circular cross section actuatable by a shaft member centered within the bushing, said bushing upon its rotation effecting said radial adjustment.

Abstract: Tool holder with controlled tool movement, comprising two members adapted to be moved angularly away from each other against a resilient force, one member carrying the tool and being movable away from the other, a push member adapted to control this movement extending through one of said members, at least one lever being interposed between said push member in order to scale the control action between said push member and said tool holder, said lever being housed longitudinally within the central passage of a tubular bore machining bar. The machining bar in conjunction with a corresponding tool-bit constitute the aforesaid members that are movable away from each other.
