  • Publication number: 20140216216
    Abstract: In a method for machining a workpiece using a tool, the tool engages with the workpiece and between the two a cutting motion is induced. Furthermore, a relative first vibration motion between workpiece and tool, which is superimposed on the cutting motion, is induced in such a way that one or more characteristic values of the first vibration motion and one or more characteristic values of the cutting motion are adjusted in relation to one another. The superimposed vibration motion can also be induced in such a way that distinctive surface zones of the workpiece are generated.

  • Publication number: 20140010606
    Abstract: A milling insert and a milling tool for the milling of a slot in a work piece. The milling insert includes an under side, an opposite upper side that forms a chip surface and is parallel to an extension plane, and an edge side disposed between the upper side and the under side. A cutting edge, which extends between the edge side and the chip surface, has a primary main cutting edge, a secondary main cutting edge, and an end cutting edge. The end cutting edge connects the primary main cutting edge and the secondary main cutting edge and borders on the primary main cutting edge at a primary transition point and on the secondary main cutting edge at a secondary transition point. A normal to the extension plane of the chip surface forms an acute clearance angle with the edge side along the cutting edge. The end cutting edge is curved from the primary transition point to the secondary transition point.

  • Publication number: 20130272807
    Abstract: A cutting tool for machining a workpiece. The cutting tool comprises a holder and at least two cutting inserts which are separated from each other by a spacer element. The cutting tool may be used to produce two or more bevels (and/or joints and/or grooves) at precisely defined spacings in only one operation. Through the use of spacer elements of different lengths, it is possible to produce bevels at different spacings. The spacer element preferably has an interface which comprises only radial contact surfaces, which run parallel to a longitudinal axis of the spacer element, and a substantially flat axial contact surface, which runs transverse to the longitudinal axis. The length of the spacer element can therefore be shortened on the rear side of the spacer element without destroying said interface.

    Abstract: A boring bar, such as for internal turning, includes a front pocket that is defined by a shelf-like surface and a ramp surface, an insert seat that is countersunk in the shelf surface and disposed asymmetrically in relation to a center axis, a chip flute that is countersunk in the outside of the bar is disposed on the same side of the center axis as the insert seat, and an internal channel that supplies a fluid to the front part of the bar. The fluid channel ends in an outlet mouth disposed on the side of the bar that is opposite the insert seat in order to guide a flow of the fluid past the insert seat toward the front opening of the chip flute.

  • Patent number: 7306412
    Abstract: An end mill 10 is a tool for milling a metal block such as a metal mold and is placed in a machine tool such as a milling machine when in use. The end mill 10 is used to provide a rotary milling cutter and a milling method using the same, in which it is possible to perform orthogonal milling and pocket milling to efficiently form four corners with small radius, without repeatedly milling using a small-diameter end mill. The end mill 10 has two cutting edges 11a and 11b at its distal portion, and an edge angle D1 formed by the two cutting edges 11a and 11b is 70.53 degrees.

  • Publication number: 20070189866
    Abstract: A tool assembly for a thermoforming machine has a tool holder having an abutment face and a tool having an abutment part. The tool and holder have a groove and a rail fittable in the groove for fitting the tool to the holder into a working position with the abutment part abutting the abutment face. A part-conical seat centered on a tool axis is formed on the tool. A pin formed with a part-conical head face complementary to the seat and centered on a pin axis is carried on the holder. The seat and head are positioned on the tool and holder such that in the working position the axes are generally parallel but slightly offset from each other and the part-conical head face is axially engageable with the seat.

  • Patent number: 7052215
    Abstract: A cutting tool with a sensor according to the present invention includes an electrically conductive substrate, an insulation film provided on a surface of the electrically conductive substrate, and a sensor circuit of an electrically conductive film provided on the insulation film. The insulation film includes two consecutive insulation layers. Even if the plural insulation layers each have defects such as cracks and pinholes which possibly impair the insulation property impair the insulation film, the defects present in the plural layers are unlikely to be continuous. Therefore, the insulation film has an improved insulation reliability, thereby ensuring proper function of the sensor circuit in the cutting tool.

  • Patent number: 7037049
    Abstract: Rotary cutting tool, in particular for high speed machining with nano-lubrication. The lubricant is fed to the end surface of the cutting part (12) of the tool through a central lubrication channel (22) drilled along the axis of rotation (10) of the tool, with one non-through end, located just near the end surface, which is connected to the latter by secondary channels (24) opening near each end cutting edge (20). Cutting parameters relating, in particular, to the end dedendum angle, the width of end clearance and the width of the circular land of each cutting edge further improve the quality of the work carried out.

  • Publication number: 20030180105
    Abstract: A tool-holding seat includes a seat body having a flat bottom face and a flat top face opposite to the flat bottom face. The seat body is formed with a plurality of parallel spaced apart bit-retention holes which extend inwardly from the flat top face. Each of the bit-retention holes is capable of retaining a workpiece-driving bit therein, and defines an axial line along the length thereof. The axial line of each of the bit-retention holes is inclined relative to the flat bottom face at an acute angle. A magnetic piece is embedded in the seat body adjacent to the flat bottom face.
