摘要： Provided are a new tool radius adjusting method in a machine tool and a new machine tool that are capable of automatically adjusting a tool radius differently from a prior-art automatic adjusting method. At a contact step, a reference portion 52c of a movable body 52 and a position adjusting reference member 83 are brought into contact by sliding the movable body 52 relative to a housing 51 so that the position of a cutting blade 70 comes to a predetermined position in a direction to go away from a rotational axis. Then, at an adjusting step, the position of the cutting blade 70 relative to the rotational axis is adjusted by changing the relative position between a tool spindle 2 and the position adjusting reference member 83 in a direction to come close to each other by drive means that is used for positioning a spindle head 102 relative to a workpiece in machining the workpiece with the cutting blade 70.

摘要： The invention relates to a reamer. Said reamer comprises a base (3), at least one cutting tip (13) and an adjusting device having an adjusting screw which acts upon the cutting tip (13) and passes adjusting forces into a lateral face of the cutting tip (13) in an area of contact. The cutting tip is arranged substantially parallel to a face (11) of the reamer (1). It has a geometrically defined major (27) and a geometrically defined minor cutting edge (29) and is held by a tightening screw (39) penetrating the cutting tip (13) on a support face (19) of the base (3) of the reamer (1), a back (17) of the cutting tip (13) resting on said support face (19). The reamer is characterized in that the recess (35) penetrating the cutting tip (13) and receiving the tightening screw (39) has a clamping region (57) and in that the distance of the clamping region (57) to the back (17), measured at a right angle to the back (17) of the cutting tip (13), is the same as the distance of the contact region of the adjusting forces to the back (17) of the cutting tip (13), measured at a right angle to the back (17) of the cutting tip (13).

摘要： The invention relates to a drilling tool comprising a tool holder, on whose front face interchangeable cutting attachments are fixed and which has a shaft part on the opposite end to said attachments and an adjusting device for minimizing the tolerance measurement determined by the drilling system. In order to improve the aforementioned adjusting device, the invention is characterized in that the tool holder (1) has groove-shaped recesses (5, 8), which lie on respective diametrically opposed sides and which are eccentrically arranged on a plane that is perpendicular to the longitudinal axis of the tool holder. Said groove-shaped recesses have a half-cylinder extension on each of the sides facing the longitudinal axis of the tool holder. A bolt (2, 3), whose dimensions correspond to the size of the cylinder, is located in each extension. The first bolt (2) is connected to a tapered adjusting element (9) using a double-threaded screw (11) which is positioned radially in relation to the tool holder (1). Said tapered adjusting element lies within a cone-shaped cavity running from the outside of the tool holder (1), in such a way that the distance to the first bolt (2) can be adjusted by rotating the double-threaded screw (11), whereby the distance that has been set determines the degree to which the groove-shaped recess (8) located on this side is further expanded or slackened, and in such a way that the second bolt (3) can be tightened in relation to the tool holder (1), using a threaded bolt (4) that engages with a continuous threaded bore of said second bolt. The latter thus counteracts the corresponding strain on the tool holder (1) in the vicinity of the groove-shaped recess (5) which lies on this side.

摘要： The invention relates to a chip removing tool comprising a tool shank (1) which acts as a support for a perforated plate (3). The perforated plate (3) is tensed by means of a screw connection passing through the orifice (19) of the perforated plate (3) and a through hole (22) of the tool shank (1), containing a screw (17) which is introduced from the side of the perforated plate, and a corresponding nut (18) positioned beneath the tool shank (1) inside the seat (4) of the tool shank (1). The tensed perforated plate (3) is adjusted in an effective manner in a direction of adjustment (3) which is substantially radial in relation to the axis of rotation (8) of the tool shank (1), whereby the contact surfaces between a) the screw head (23) and the perforated plate (3) and b) the head (24) of the corresponding nut (18) and the tool shank (1) enable a pivotable movement of the screw connection following on from the adjustment movement, said screw connection consisting of a screw (17) and a corresponding nut (18), as a result of crowning.

摘要： The invention relates to an advancing system for a rotary cutting tool which is driven by a spindle (6) and can be moved in the direction of advancement by means of a regulating device. Said regulating device is driven by an operating spindle (25) which can be driven by means of its own advancing motor (56), synchronously with the spindle (6) or with a speed difference predetermined in relation to said spindle (6). When the operating spindle (25) and spindle (6) are driving the regulating device synchronously no advancement will occur, whereas when a speed difference is set by means of the regulating device, the cutting tool is moved. The operating spindle (25) and the spindle (6) operate at the same speed again after the desired position of the cutting tool has been set.

摘要： A tool head, in particular a fine adjustment head for use in machine-tools, may be coupled to a rotary machine spindle (26) and has a slide (16) that may be adjusted transversely to the axis (12) of the base body and is provided with a projecting tool-receiving part (14) on its front face. A measurement arrangement (18) is provided for directly measuring the adjustment path of the slide (16) in relation to the base body (10). The tool head further has an adjustment motor (20) that acts on the slide (16) in the direction of adjustment and an external current supply arrangement (22) for electronic components integrated into the tool head and for the adjustment motor (20). In order to obtain a compact design with high adjustment precision, the adjustment motor (20) is arranged with its cylindrical housing (45) in a recess (46) of the base body (10) that extends transversely to the direction of adjustment of the slide (45) and to the axis of the base body. The recess (46) extends across the axis (12) of the base body and the driven shaft (48) of the motor extends parallel to the recess (46).
