Patent number: 10010942Abstract: A non-indexable, one-sided cutting insert includes opposite insert side surfaces which define an insert width therebetween, opposite insert front and rear surfaces which extend between the insert side surfaces and define an insert depth therebetween and opposite insert top and bottom surfaces which extend between the insert side surfaces and the insert front and rear surfaces. The insert top and bottom surfaces define an insert height therebetween. The insert further includes a main cutting edge formed at an intersection between the insert top and front surfaces. A maximum value of the insert width is smaller than minimum value of the insert height, and a minimum value of the insert depth. The insert includes a deep opening which opens out only to the insert bottom surface and defines an opening depth. A depth ratio defined between the opening depth and the insert height is greater than 0.3.Type: GrantFiled: June 20, 2016Date of Patent: July 3, 2018Assignee: Iscar, Ltd.Inventor: Shimon Athad

Publication number: 20170136549Abstract: A cutting tool having a tool holder, cutting insert and clamping member. The tool holder includes an elongated supporting surface extending in a rearward-to-forward direction. The cutting insert has a central portion and three cutting portions, the central portion having two opposing side surfaces and three spaced apart locating surfaces defining a first imaginary triangle. The cutting insert is indexable about a central axis intersecting the two side surfaces. Each locating surface intersects two of three bisector planes containing the central axis and bisecting respective corners of the first imaginary triangle, and the cutting edge of each cutting portion is located entirely outside of the first imaginary triangle. In each index position the clamping member is located entirely rearward of a first vertical plane containing the central axis and perpendicular to the rearward-to-forward direction, and one of the locating surfaces is in clamping contact with the supporting surface.Type: ApplicationFiled: November 18, 2015Publication date: May 18, 2017Inventor: Shimon ATHAD

Patent number: 9616585Abstract: A slitting tool configured for fine-tuning thereof includes basic body, which in turn includes a body portion and a cutting portion extending therefrom. The slitting tool includes a biasing screw which is seated in a biasing bore and is configured to adjust the position of the cutting portion. The biasing screw is configured to engage a biasing surface of the body portion to adjust the cutting portion's position. The biasing surface is oblique relative to the biasing screw for retarding movement of the biasing screw a fine-tuned position.Type: GrantFiled: June 13, 2013Date of Patent: April 11, 2017Assignee: Iscar, Ltd.Inventor: Shimon Athad

Patent number: 9409236Abstract: A turning and face grooving tool body has a pocket and a pin. The pin has a unitary one-piece construction and an elongated shape which defines a longitudinal direction along a pin axis. The pin includes pin top and bottom ends, a pin peripheral surface which extends therebetween, and a pivot protrusion which extends outwardly from the pin peripheral surface. The pin is rotationally asymmetric about the longitudinal pin axis. The pocket includes a base surface, transverse support walls, and a pin bore which opens out to the base surface and includes a pin bore inner surface. The pin is located in the pin bore and the pin top end protrudes beyond the base surface. The pivot protrusion is spaced apart from the pin top and bottom ends, offset in the longitudinal direction from a pin midway-point which is located midway between the pin top and bottom ends.Type: GrantFiled: July 23, 2014Date of Patent: August 9, 2016Assignee: Iscar, Ltd.Inventor: Shimon Athad

Patent number: 9216461Abstract: A cutting body for a metal-working machine tool includes a cutting portion extending from a body portion. The body portion is configured to fine-tune the position of the cutting portion. The body portion includes an inner sub-portion and an outer sub-portion disposed between the inner sub-portion and the cutting portion. The outer sub-portion includes adjacent first and second sections. The first section is configured to elastically bend, extends between the inner sub-portion and the cutting portion, and comprises a face adjacent the second section. The second section includes a biasing surface and a biasing sub-portion configured to hold a biasing member. When the biasing sub-portion is moved due to biasing of the biasing member against the biasing surface, the first section is configured to bend and thereby change position of the cutting portion extending therefrom and allow fine-tuning thereof.Type: GrantFiled: July 6, 2012Date of Patent: December 22, 2015Assignee: Iscar, Ltd.Inventor: Shimon Athad
