  • Patent number: 6783444
    Abstract: The tool comprises a tool wheel (5) which is mounted on a holding arm (4) and has a tool-wheel parent body (6) having a machining body (7) arranged at the outer margin. In one embodiment variant, this machining body is designed as an abrasive body. A base body for accommodating the bearing arrangement is designed in one piece with the holding arm (4), which also has the supply lines (8) for the hydrodynamic bearing arrangement and the hydraulic drive. A tool-centering interface (11) permits the presetting of the tools outside the machine tool.

  • Patent number: 6062969
    Abstract: A grinding wheel is disclosed with a disk-like, cylindrical shape, whose perimeter is equipped with a grinding abrasive and has at least one spiral groove. The groove extends essentially around the perimeter at an acute bevel angle of inclination less than 45.degree. to a radius line normal to the axis of wheel rotation. Preferably the bevel angle is designed as an acute angle and is sized so that the groove extends over at least one full circumference of the grinding wheel. The face of the ribs may be tapered and the corners chamfered. Multiple parallel or non-parallel grooves may be employed. Improved cutting, service life and surface characteristics of the processed workpiece are obtained.

  • Patent number: 5476436
    Abstract: The invention concerns a chain magazine designed to hold the machining tools for machining devices, in particular tooling machines. The magazine comprises a continuous chain fitted with holder devices for the machining tools and driven by at least two sprockets and guided by guide elements up to the point of contact with the pitch diameter of the drive or guide sprocket wheel. The chain magazine further comprises chain links consisting of a connecting bar and, joined to the bar, two tubular sleeve elements of different diameter which form the flexible couplings between the links. Holder devices for machining tools are disposed coaxially to the hinge axes in the mutually encircling tubular sleeves under a small motion clearance. Shaft-like cutouts are furnished in each of the tubular sleeves and exhibiting parallel faces disposed spaced apart and directed toward the center axes of the holder devices.

  • Patent number: 5437592
    Abstract: Device for metal cutting a workpiece in a clamping fixture by using tools (WZ) which are removable in alternating sequence from a tool magazine with a sequence control of the machining steps and with a tool spindle unit changing device (4) and with a tool changing device comprised of a movable and rotatable as well as pivotable tongs-type grasp (ZG), the grab jaws (28, 29) of which being aligned to the respective tool removal axis and spindle axis (Z), and a mirror-image jaw profile (30) to receive tools (WZ) with more than two different shank or taper sizes with at least three adjoining arched sections (a, b, d), the radii (ERa, ERb, ERd) of which match the different diameters of at least three shank or taper sizes, and in which the tool spindle unit (10) which is in the working position is insertable into and removable from a receptacle and exchanged for a tool spindle unit (11) in a stand-by position.
