| 407013000 | RECTILINEAR BROACH | 13 |
| 20110020078 | HELICAL BROACH FOR ROUGHING - A helical broach | 01-27-2011 |
| 20130156513 | HELICAL BROACH - This helical broach forms a twisted groove at the inner circumference of a machined hole of a workpiece by a plurality of cutting teeth, the plurality of cutting teeth include a plurality of circumference cutting teeth which are arranged on the tip-end side of the broach body, and include a plurality of tooth thickness cutting teeth which are arranged on the rear-end side of the broach body. The plurality of tooth thickness cutting teeth include cutting edges and guiding edges, respectively. The tooth thickness cutting tooth positioned closest to the rear-end side of the broach body is provided with the guiding edge instead of the cutting edge at the intersecting ridge part between a rake face and a lateral surface facing one wall surface of both groove wall surfaces of the twisted groove of the workpiece. | 06-20-2013 |
| 20140255112 | BROACH TOOL RAKE FACE WITH A TAILORED SURFACE TOPOGRAPHY - A broach tool includes a broach tool rake face with a tailored surface topography. | 09-11-2014 |
| 20140294521 | BROACH - A plurality of cutting edges that are arranged on an outer circumference of a shaft-shaped broach body are provided with a spline teeth group, which contains a plurality of spline teeth 8 that groove a prepared hole of a work material, and a round teeth group, which is disposed in a different position from the spline teeth group along an axis direction and contains a plurality of round teeth that machine an inner circumference of the prepared hole. At least one gullet is formed to extend along the outer circumference of the broach body in a circumferential direction around the axis between the round teeth that are adjacent to one another in the axis direction in the round teeth group. The gullet extends toward the axis direction, gradually twisting toward the circumferential direction. The spline teeth group and the round teeth group are formed integrally on the outer circumference of the broach body. | 10-02-2014 |
| 407014000 | Hollow tool for surrounding workpiece | 1 |
| 20100196106 | BROACH SHAVING APPARATUS | 08-05-2010 |
| 407015000 | Including holder having seat for inserted tool | 5 |
| 20120195699 | BROACHING TOOL AND METHOD OF MANUFACTURE - A broaching apparatus includes a first tooth having a front face, a rear face opposite the front face, and a first cutting surface have a lobed shape extending along a first side of the first tooth between the front face and the rear face. A first interface defined between the first cutting surface and the front face is offset relative to a second interface defined between the first cutting surface and the rear face in a direction that is substantially perpendicular to an axis of tooth movement for broaching operations to provide tool clearance rearward from the first interface. A method of making a broach cutter is further provided. | 08-02-2012 |
| 20150147126 | TURN BROACH MACHINE - A turn broach machine includes: a machining member machining a target to be cut; and an adaptor provided under the machining member, supporting the machining member, and adjusting a position of the machining member. At the time of adjusting a position of a segment of the machining member from a plate provided in an adapter, the segment does not manually move, but moves on an adjusting plate that is mechanically defined, such that work accuracy may be improved to increase marketability and a work time may be decreased to improve work convenience and productivity. | 05-28-2015 |
| 20150336192 | HELICAL BROACH - The shell of this helical broach ( | 11-26-2015 |
| 407016000 | Annular tool | 1 |
| 20100104382 | TOOL - The invention relates to a tool for the outside milling or for the rotary broaching of tools that rotate about the longitudinal axis thereof during machining, comprising a disk-shaped tool carrier comprising peripherally arranged cutting inserts ( | 04-29-2010 |
| 407017000 | Including single tooth | 1 |
| 20090297281 | Broaching Tool - A broaching tool for machining a workpiece formed of a parallelogram shaped insert which fits within a slot formed in a body member. The insert has two juxtaposed corners either of which may be oriented at the distal end of the body member to function as a cutting edge. Repositioning of the insert to place either cutting edge in place is provided by flipping it over in its engagement within the slot. The inserts may be provided in a kit of differently configured inserts to yield different cutting widths. | 12-03-2009 |
| 407018000 | Plural tooth groups | 3 |
| 20130156514 | PUSH BROACH - A push broach, for machining a quadrilateral hole or quadrilateral groove, includes a shank portion and a cutting portion connected to the shank portion. The cutting portion includes at least one pair of cutting teeth including a first cutting tooth and a second cutting tooth arranged substantially parallel to the first cutting tooth, the first cutting tooth includes a pair of first cutting edges at two opposite edges thereof, the second cutting tooth includes a pair of cutting edges at two opposite edges thereof, when viewed from an end of the shank portion, each second cutting edge interconnects the pair of first cutting edge, and the pair of the first cutting edges and the pair of second cutting edges cooperatively form a quadrangle enclosing a periphery of the first cutting tooth. | 06-20-2013 |
