Cutting tools and holders

A cutting tool includes a holder and at lest two first cutting inserts. The holder has a number of insert pockets in order to receive those cutting inserts. The cutting inserts are mounted in the holder such that their radially outermost portions lie substantially in an imaginary circle. The circle constitutes an effective diameter of the cutting tool. The cutting tool, in addition, includes at least one second cutting insert provided for a machining operation different from that of the first cutting inserts. The second cutting insert is spaced radially inwardly from the circle.

Machine tool for the production of base structures for false teeth

The invention relates to an automatic machine tool (10), for the production of base structures (68), for false teeth, in particular, for tooth crowns and/or tooth bridges of exact three-dimensional shape. Said base structures (68) may be fixed to prepared natural and/or artificial tooth stumps. The machine tool (10) comprises a machine frame (12, 14), or a body, a work piece carrier, with a rotation shaft (38), at least one digitisation unit (46), at least one machining unit (52) and an electronic arithmetic and control unit (50) for all drive lines. A carrier for the workpiece, a blank (42), and/or for the machining unit(s) (52), serves as displacement unit, with three translational axes in the x-, y- and z-directions. The digitisation of the preparation model (44) and the machining of the blank (41) are carried out on the same machine tool (10), at different times. The machining paths for the blank (42) are calculated from the measured and stored digitised data and a predetermined material-specific scaling factor, before the machining of the blank.

Method and an arrangement for the production of insert bodies for the artificial rebuilding of teeth and human limbs

ABSTRACT An arrangement is used for the efficient mass production of individual bodies for the artificial rebuilding of teeth, for example. The arrangement comprises a first pair of co-rotating elements, of which the first element (1) is so arranged as to support a replica (21) of a body which is to be produced, and the second element (2) is so arranged as to support a blank from which the body is to be produced. The replica and the blank are caused to rotate synchronously about the axis of rotation (3, 4) of the respective element. In a second pair of elements a third element supports a sensing device (31) which is capable of interacting with the external contour of the replica, and a fourth element supports a tool (52) by means of which the blank is capable of being machined. The first and second pairs of elements are capable of being displaced relative to one another. The fourth element is adjustably connected to the third element (29) in such a way that the tool executes movements which correspond to the shape of the external contour of the replica sensed by the sensing device (31).

Cutting tool and a holder for chip removing machining

Cutting tool and holder

The present invention relates to a cutting tool and a holder for chip removing machining. The cutting tool (10) comprises a holder (11) and at least two first cutting inserts (12A-12D). The holder (11) comprises a number of insert pockets (17) in order to receive the cutting inserts (12A-12D). The cutting inserts are mounted in the holder (11) such that their most peripheral parts relative to a center axis (CL) of the holder lie substantially in a circle (C). The circle (C) constitutes a diameter of the cutting tool 810). The cutting tool (10) in addition comprises at least one second cutting insert (13-16) provided for another machining than the first cutting inserts, said second cutting insert being provided radially inside of the circle (C).

Device for engraving intaglio printing cylinders

A device for engraving intaglio printing cylinders is provided having the engraving needle cutting the small screen cups in the intaglio printing cylinder and the scanning element applied to the cylinder jointly supported in a holding device. The scanning element is engaged by a damping element having a piston supported on a pressure spring and guided in a cylindrical casing. A tappet is connected to the piston and engages the scanning element or a handwheel mounted on such element. Motions of the scanning element in the direction of its longitudinal axis are damped by the damping element thereby eliminating undesirable vibrations of the holding device and thus of the engraving needle.

Improvements in or relating to a copying metal cutting machine

471,108. Hydraulic transmission of power; fluid - pressure servomotor - control systems. KAIN, C. H. Jan. 27, 1936, No. 2563. [Classes 69 (ii) and 135] [Also in Group XXII] In a metal-cutting copying-machine having a tool and tracer traversed over the surface of the work and pattern, hydraulically controlled means are provided actuated by the tracer to cause movement of the cutter to or from the work, and further means actuated by phase movement of the tool relatively to the tracer are provided to maintain the tool and tracer in fixed relationship in the direction to or from the work and pattern. As applied to a milling or boring machine, the pattern 6 and work 7, Fig. 1, are mounted on a common support 5 capable of being traversed along a carriage 3 which is movable to and from a fixed column 2 carrying the tracer 21 and cutter 15. The saddle 14 carrying the tracer and cutter spindles is movable vertically on the column 2 by a screw 12, this screw and the mechanism for traversing the support 5 and carriage 3 being controlled by hand levers 8, 11, &c. The cutter spindle 16 is driven through a splined shaft 17 from a motor 18. The tracer casing 27 is secured to a slide 20 adjustable relatively to the saddle 14 to vary the distance between tracer and cutter according to the size of pattern and work by means of a screw jack 22 locked by a nut 24. The tracer tip 21, Fig. 7, is mounted on a shank 60 slidable in a tube 61 and is pressed towards the pattern by a spring 89, the tube 61 being universally mounted by means of a ball joint 62 in a tube 26 slidable within an extension 46 of the casing 27. A rod 66 is attached at one end to the shank 60 and at the other to a piston valve 70 slidable within a piston 41 which is slidable within the casing 27 and is attached to a tube 40 passing through a gland 44 in the casing 27. A piston 47 sliding in a cylinder 28 attached to the casing 27 is secured to the tube 40 which passes through a gland 43 in the cylinder and receives ...
