20130251463 | CUTTING TOOL WITH COOLING MECHANISM AND A CUTTING INSERT AND TOOL HOLDER THEREFOR - A cutting insert ( | 09-26-2013 |
20120230787 | CUTTING TOOL, CUTTING TOOL HOLDER, AND A CUTTING INSERT THEREFOR - A cutting tool holder configured for mounting a cutting insert to form a cutting tool that extends along a central axis and comprises a mounting portion having a seat surface oriented generally perpendicular to the central axis. The tool holder has at least two securing extensions projecting from the seat surface in a direction generally parallel to the central axis. Each of the extensions are formed, at an end remote from the seat surface with a latch portion extending towards the central axis. The latch portion has an under and top surface, both oriented generally transversely to the central axis such that the under surface is disposed between the seat surface and the top surface. Each of the extensions is formed with a side surface extending between the under and side surfaces to form a securing pocket defined between the seat, side, and under surfaces. | 09-13-2012 |
20110305532 | CUTTING TOOL, CUTTING TOOL HOLDER AND CUTTING INSERT THEREFOR - A cutting tool holder adapted for mounting thereon a cutting insert to form a cutting tool. The cutting tool holder comprises an insert seat defined by a base and at least one side wall extending from the base to define an insert seat space adapted for receiving the cutting insert. The cutting tool holder further comprises a support element extending into the insert seat from the base. The support element is (i) integrally formed with the insert seat or (ii) at least during operation, fixedly attached to the insert seat. The support element is formed with an undercut surface extending, at least during operation, at an acute angle to the base and away from the side wall. The insert seat is formed with a bore configured for receiving a fastening member for engagement with the insert seat. The fastening member is displaceable with respect thereto between a mounting position configured for allowing the cutting insert to be mounted onto the insert seat and a securing position adapted for securing the cutting insert within the insert seat. | 12-15-2011 |
20100310329 | CUTTING TOOL WITH PROTRUSIONS, AND METHODS OF USE THEREOF - A cutting element adapted for removing a chip from a surface of a workpiece has at least one cutting edge defined by an intersection line between a rake and a relief surface and is formed with one or more workpiece deforming protrusions. At least a portion of the protrusions is spaced from the cutting edge such this portion protrudes, along a plane perpendicular to the relief surface and passing through the cutting edge, in a direction transverse to the relief surface beyond the cutting edge. At least the projecting portion of at least one of the protrusions is constructed so as to deform the workpiece before its contact with the cutting edge. | 12-09-2010 |
20100183364 | ATTACHMENT MECHANISM - Provided is an attachment arrangement including a first member for securely attaching thereon a second member having a top face, a bottom face and formed with a second member bore having an inner surface extending between the top and the bottom face. The first member includes an attaching portion defined by a bottom surface and at least one side wall angled to the bottom surface, an attaching portion bore with a bore axis, and a securing mechanism. The securing mechanism includes a securing pin within the attaching portion bore and has a body with an outer surface extending between a proximal end and a distal end of the body. The securing mechanism further includes a displacement arrangement for axially displacing the securing pin along the bore axis of the attaching portion bore between at least a first, attaching, position and a second, securing, position. | 07-22-2010 |
20100111621 | CUTTING TOOL HOLDER AND A CUTTING INSERT THEREFOR - Disclosed is a cutting tool holder for mounting a cutting insert having a top face, a bottom face and an insert bore having an inner surface extending between the top and the bottom faces. The holder includes a seat having a bottom surface and at least one side wall angled to the bottom surface, a seat bore with a bore axis having an open end at the bottom surface of the seat, and a securing mechanism for securing the cutting insert in the seat. The securing mechanism includes a securing pin within the seat bore and a body with an outer surface extending between a proximal end and a distal end of the body. The securing mechanism includes a displacement arrangement separate from the securing pin for axially displacing the securing pin along the bore axis of the seat bore between a first, mounting position and a second, securing position. | 05-06-2010 |
20090092451 | Cutting tool holder and a cutting insert therefor - A cutting tool holder adapted for mounting thereon a cutting insert having a top face, a bottom face and formed with an insert bore having an inner surface extending between the top and the bottom face. The holder comprises a seat defined by a bottom surface and at least one side wall angled to the bottom surface, a seat bore with a bore axis having an open end at the bottom surface of the seat, and a securing mechanism for securing the cutting insert in the seat. The securing mechanism comprises a securing pin received within the seat bore and having a body with an outer surface extending between a proximal end and a distal end of the body and defining a pin axis therealong. The securing mechanism further comprises a displacement arrangement adapted for axially displacing the securing pin along the bore axis of the seat bore between at least a first, mounting position in which the distal end protrudes from within the seat bore through the bottom surface into the seat to a first extent so as to allow the cutting insert to be placed within the seat, having its bottom face aligned against the bottom surface, and a second, securing position in which the distal end protrudes from within the seat bore through the bottom surface into the seat to a second extent, greater than the first extent, so as to engage the inner surface of the insert bore, thereby securing the insert in place. | 04-09-2009 |
