Abstract: A cutter build and truing machine (22) comprising a mechanism (52, 54) to position cutting blades (98) by moving the blades in either direction in a mounting slot (96) of a cutter head (94). The machine further includes a torque spindle (62) and driver (66) to automatically tighten or loosen clamp bolts (102).

Abstract: A low profile peripheral cutter (18) with stick blades (6). The cutter has a cutter body (30) and a flexible clamping disk (20) to clamp all blades. The flexible clamping disc includes a slot (24) between each cutting blade (6) in order to provide a plurality of blade clamping web wings (26) each of which acts like a deflection beam to hold the blades in position. Preferably, each web wing (26) covers one stick blade (6) and each web wing has two contacting pads (36, 38) to press each blade into its seating surface (44, 46) thereby holding the blade in position.

Abstract: A method of grinding the tooth slots of a workpiece with a freshly dressed grinding wheel wherein dual-machining of tooth slots is eliminated. The method comprises grinding the first few slots of a gear at a corrected depth amount which accounts for the rapid wear and other conditions of the freshly dressed grinding wheel wherein for a first number of tooth slots (e.g. 1, 2, 3 or more), the grinding wheel is fed-in relative to the workpiece by the corrected depth amount.

Abstract: A cutter head (40) having cutting blade positioning slots (50, 52) wherein a portion of the positioning slots accommodate cutting blades (42) for right-hand cutting and another portion of the positioning slots accommodate cutting blades (46) for left-hand cutting.

Abstract: A bevel gear manufacturing face cutter head (2) for face hobbing and face milling wherein the cutter head includes positive blade seating surfaces (16, 18) and the capability to clamp the blades (8) tight to the positive seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.

Abstract: A method of machining a bevel gear (22) having teeth with a pitch angle greater than 90 degrees comprising providing at least one tool (42, 44) rotatable about a tool axis with the tool comprising a disc-shaped body (43) having a periphery (49) and at least one stock removing surface (45, 47) arranged about the periphery. The tool is rotated and fed relative to the gear to effect machining of at least one tooth surface wherein the machining is carried out in a non-generating manner.

Abstract: A bevel gear manufacturing face cutter head (2) for face hobbing and face milling. The cutter head has blade positioning slots (20) having a four-sided shaped cross-section and positive blade seating surfaces (22, 24). The cutter head also has the capability to clamp cutting blades (8) tight to the positive blade seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.

Abstract: A skiving tool comprising a cutter head (2) having a plurality of cutter blade mounting and positioning slots (8) arranged spaced, preferably equidistant, about the periphery (7) of the cutter head with the blade slots, and hence the cutting blades (4), preferably oriented perpendicular to the axis of rotation (A) of the cutter head. Alternatively, the blade slots may be inclined from the perpendicular orientation by less than 50 degrees, preferably less than 20 degrees, thereby forming a conical shaped cutter. Additionally, the blade slots may be positioned to extend radially from the cutter head axis whereby the longitudinal axis of a cutter blade will intersect the cutter head axis, or the blade slots may be radially offset from the cutter head axis. The blade slots may have any cross-sectional shape such as square, rectangular or those types having generally V-shaped seating surfaces (10) comprising a pair of angled mounting surfaces (12, 14) each less than 90 degrees.

Abstract: A bevel gear manufacturing face cutter head (2) for face hobbing and face milling wherein the face cutter head includes a positive blade seating and stick-type rectangular or square cross-section cutting blades (6) are clamped tight to the positive seating surfaces (14, 18). The cutting blades are adjustable radially by axial movement by a non-self-locking system.

Abstract: The invention concerns a method for the machining of toothed workpieces, in particular for the plastic reshaping of the tooth edges at the ends of the teeth through a meshing tooth engagement with a tool that is rotatable with free-running mobility about its axis of rotation, in particular a chamfering tool, wherein between the machining of one workpiece and the next, the tool is subjected to a traverse movement, whereby the tool is caused to perform a rotary movement so that, if a tool region (6a, 6b) that is designed for the initial engagement with the work pieces is not suitably positioned, it is brought into a position that is suitable for the machining of the next work piece, wherein the rotary movement is effected by coupling the rotary movement at least in sections to the traverse movement.

Abstract: A method and a device for the fine-machining of a toothed workpiece with a toothed finishing tool (10) which meshes with the workpiece in mutual tooth engagement are, for the purpose of producing conically modified tooth flanks, designed according to the invention in such a way that in the dressing process the finishing tool (10) and the dressing tool (11) are set at a position of reduced center distance (a) that is offset from a position of maximum center distance.

Abstract: A fluid supply apparatus (2) for a machine tool comprising a header portion (4) and one or more fluid manifolds (6, 8) attachable to the header wherein the fluid manifolds are quickly and easily replaceable on the header without the use of tools.

Abstract: A motion which creates an end relief and which is integrated into the plunging cycle of non-generated bevel gears. The tool, after feeding to the correct tooth forming position in case of non-generated gears, is swung sideways out of cutting or grinding contact with the slot instead of along a withdraw path which is identical to the plunge path but opposite in direction.

Abstract: Generating cutting processes for producing bevel gears and employing a single rotary disc cutter (36) wherein a portion of the generating cutting process effectively includes a reduction (38) of the workpiece roll angle (40) during generating thereby reducing or eliminating cutting action on the clearance side (42) of the rotary disc cutter.

Abstract: Method and apparatus for lapping gears which includes an active torque system to substantially improve the lapping process with respect to run-out and other longer-term motion transmission errors without compromising tooth-to-tooth performance. Motion transmission error measurements provide the basis for calculating a corrective active torque component which is combined with conventional process torque to reduce or eliminate part run-out.
