| 082100200 | RADIALLY MOVING ROTATING TOOL INSIDE BORE | 10 |
| 20090249925 | Tool Head with Adjusting Motor - A tool head includes a working slide which can be adjusted relative to a basic body, and an electric adjusting motor which acts on the working slide via gears. The motor includes a stator and a rotor which runs round in the stator, bears an output shaft and is mounted in two pivot bearings arranged at a distance from one another, wherein one of the pivot bearings is arranged with an outer ring in a basic body-mounted stator housing and with an inner ring directly or indirectly on the output shaft. The stator housing includes a sleeve which engages and is fixed to the stator for rotation and displacement, and a bearing cover which closes off the sleeve on the gear side and bears the outer ring of the first pivot bearing. The second pivot bearing is arranged in a separate centring ring fastened inside the stator. | 10-08-2009 |
| 20110303057 | PRESSURE-ACTIVATED ID GROOVING TOOL - A pressure-activated ID grooving tool includes a tool body having a channel, a front cross slide slot, a rear cross slide slot projecting, and two legs extending from a piston bore. A piston is disposed within the piston bore. A slide arm has an extension face and a retraction face. A cross slide has a cross slide pocket with a slide engaging face immediately opposing the extension face of the slide arm and a slide retracting face immediately opposing the retraction face of the slide arm. When fluid within the channel and the piston bore is pressurized, the piston moves toward the plunger, which in turn causes the extension face of the slide arm into contact with slide engaging face of the cross slide to cause the cross slide to move in an outward radial direction, thereby pushing the insert into contact with a workpiece. | 12-15-2011 |
| 20110303058 | MECHANICAL-ACTIVATED ID GROOVING TOOL - A mechanical-activated inner diameter (ID) grooving tool includes a shank, a body, a stopper, an insert cartridge, a bushing and an end cap. The shank includes a tapered piston having an extension surface and a retraction surface. The insert cartridge includes a tapered piston pocket having a piston-engaging face and a piston-retracting face. Axial movement of the tapered piston in a first direction causes the extension surface of the tapered piston into contact with the piston-engaging face of the insert cartridge, thereby causing the insert cartridge to move in a radially outward direction. Axial movement of the tapered piston in a second, opposite direction causes the retraction surface of the tapered piston into contact with the piston-retracting face of the insert cartridge, thereby causing the insert cartridge to move in a radially inward direction. | 12-15-2011 |
| 20130167695 | TOOL HEAD FOR USE IN MACHINE TOOLS - The invention relates to a tool head for use in machine tools, comprising a main body which can be rotated around an axis of rotation. The tool head has a slide. The slide can be moved by means of a pull rod axially oriented in the main body. The slide can be fitted with at least one tool or one tool holder. At least one adjustable toothed plate is fixedly arranged on the slide. The toothed plate comprises a helical gearing functioning as a gear means for engaging with a helical gearing of the pull rod which is complementary thereto. According to the invention, the slide has an adjustment unit for moving the at least one toothed plate and the helical gearing thereof into the complementary helical gearing of the pull rod. | 07-04-2013 |
| 20150020654 | BORING AND FACING HEAD - A boring and facing head, rotatively driven by the mandrel of a machine tool, with a turning tool mounted on a mounting slide, which may be controllably driven transversely of the axis (X) of the head body by a threaded shaft ( | 01-22-2015 |

| 20110023667 | METHOD AND DEVICE FOR BORING NON-ROUND HOLE - A non-round hole boring device capable of machining a work in a desired cross sectional shape by a simple configuration. The non-round hole boring device ( | 02-03-2011 |
| 082100400 | Tool simultaneously moving axially | 4 |
| 20100083799 | Device for inner turning - The invention relates to a device, rotating and with variable diameter, for the inner machining of pieces. In one embodiment, the device includes a fixing body, a rotating support generally in the shape of a cup suited to house a tool carrier spindle and set it in rotation, and a mechanism for the radial translation of the tool carrier spindle in the cup-shaped rotating support. The tool carrier spindle is housed in the cup-shaped support and translates in a radial direction with respect to the axis of the cup-shaped support. The cup-shaped rotating support rotates around its own axis and is preferably set in rotation by a stepping or variable-speed electric motor controlled via PLC. | 04-08-2010 |
| 20110079120 | LONG SHAFT INNER SURFACE MACHINING APPARATUS AND METHOD THEREFOR - A long shaft inner surface machining apparatus of the present invention includes: a long shaft support device | 04-07-2011 |
| 20110265615 | INTERNAL MACHINING APPARATUS FOR HOLLOW WORKPIECE - In an internal machining apparatus for machining an internal surface of a hollow workpiece, a machining unit holding a cutting blade is configured to be inserted into the hollow workpiece. A pair of unit holding arbors which are capable of non-rotatably holding the machining unit, inserted in the hollow workpiece, at both sides thereof are respectively supported by a work head and a foot stock to advance and retract in an axial direction thereof. A turning mechanism is provided to be supplied with a drive power transmitted through the interior of one of the unit holding arbors for turning the cutting blade held on the machining unit about an axis orthogonal to an axis of the unit holding arbors. | 11-03-2011 |
