| 20110027031 | Processing Head - The present invention relates to a processing head for processing machines, preferably tooth milling and tooth grinding machines, comprising a direct drive which is arranged in a processing head bed of a processing machine, wherein the direct drive comprises at least two motors actuatable in synchronism with each other. | 02-03-2011 |
| 20120263549 | GEAR MACHINING MACHINE - A gear machining machine has a cutter head with improved rigidity. The machine is equipped with a movement base that is movably supported and rotatably supports a rotation table on which an external gear or an internal gear is mounted; a bridge section of a gate-shaped column provided at a location above the movement base; a saddle which is supported by the bridge section in a vertically movable manner; and a cutter head on the front surface of the saddle, the lower end of which rotatably supports a tool. A protrusion which projects forward is provided on the front surface of the cutter head. The tool is disposed so that the front thereof protrudes further forward of an end surface which is the most forward projecting portion of the protrusion. | 10-18-2012 |

| 20080206007 | Slotting cutter and inserts for same - The present invention is directed to an insert, a slotting cutter assembly and a method for machining a plurality of slots in a metallic alloy part. The insert may comprise a cutting edge, at least one primary radius, at least two secondary radii and a clearance angle. The cutting edge may form a narrow outer end at a tip of the insert and a larger width region at a distance inward from the narrow outer end. The clearance angle may extend rearward from the cutting edge. The slotting cutter assembly may comprise a plurality of inserts and a cutter body. The cutter body may comprise a plurality of retaining slots and a plurality of support portions. The retaining slot may be configured to receive the insert. The support portion may provide support for the insert. | 08-28-2008 |
| 20090041555 | MACHINING A RACE GEAR OF A CONSTANT-VELOCITY JOINT - Race grooves and lobe outer surfaces of a constant-velocity race gear centered on a gear axis are finished by engaging a first groove of the race gear with a rotating groove-machining tool and relatively moving the race gear and rotating groove-machining tool arcuately to finish the first groove while holding the race gear against rotation about its gear axis. Then the first groove of the race gear is disengaged from the rotating groove-machining tool while holding the race gear against rotation about its gear axis. Then the race gear is rotated about its gear axis to align a second groove with the rotating groove-machining tool while engaging a first lobe outer surface with a rotating surface-machining tool to finish same. These steps are repeated in the same order to finish the second groove and a second lobe outer surface and so on until all the grooves and lobe outer surfaces of the race gear are finished. | 02-12-2009 |
| 20120207558 | TOOTH PLANE MACHINING METHOD - Provided is a method for machining a tooth plane that is formed on a circumferential surface of a cylindrical toothed member and that extends along a center axis of the toothed member. The method includes: cutting the tooth plane by a peripheral cutting edge of an end mill while keeping a rotation axis of the end mill at a predetermined steady orientation and moving the end mill parallel to the center axis of the toothed member; rotating the toothed member by a predetermined angle around the center axis of the toothed member; and cutting the tooth plane by the peripheral cutting edge of the end mill while keeping the rotation axis of the end mill at the steady orientation and moving the end mill parallel to the center axis of the toothed member. | 08-16-2012 |

| 20120076598 | MILLING MACHINE FOR PRODUCING TOOTHED WHEELS - A milling machine for producing toothed wheels has a workpiece receiver for receiving a workpiece to be toothed, which workpiece receiver can be pivoted relative to a machine frame about a workpiece pivot axis. To produce the tooth system, two machining units with two tool spindles are provided to receive milling tools. A first tool spindle can be moved linearly relative to the workpiece receiver in at least two directions and can be pivoted about a spindle pivot axis, which runs parallel to the workpiece pivot axis. A second tool spindle can be moved linearly relative to the workpiece receiver in at least two directions. The milling machine has high manufacturing productivity and flexibility and, in particular, also allows the production of tooth systems with an uneven number of teeth. | 03-29-2012 |

| 20150043985 | GEAR MACHINING APPARATUS - A gear machining apparatus causes a machining tool and a workpiece to rotate at a high speed in synchronization with each other to machine a highly accurate gear through cutting. The machining tool is manufactured such that each of pitches between tool blades of the machining tool is an integer multiple of a pitch between teeth of the gear, the integer multiple being equal to or larger than double. By using the machining tool for cutting performed by the gear machining apparatus, the number of the tool blades of the machining tool, which are brought into contact with the workpiece at the same time, is reduced. Thus, it is possible to suppress occurrence of self-excited vibrations during cutting by reducing the cutting resistance. Thus, it is possible to enhance the tooth trace accuracy of the gear. | 02-12-2015 |
