20090238649 | Indexable insert and use of the indexable in a solid drill - The invention relates to an indexable insert for solid drills comprising four identical cutting edges ( | 09-24-2009 |
20090283975 | Junction Between Two Components of a Rotating Tool System - The invention relates to a junction ( | 11-19-2009 |
20100183384 | Machine tool and cutting ring for a machine tool - The invention relates to a machine tool for use in tool machines, comprising a cutting element which is preferably configured as a cutting ring and at least two insert seats that are provided in the cutting element at distance to each other in the circumferential direction. The insert seats are fitted with at least one group of at least two identical insert tips that are detachably arranged therein and that have one working edge each, the effective working edges of the insert tips of one group being cut to the same nominal size. The insert tips are configured as indexable inserts, every single indexable insert of a group being associated with a defined insert seat in all possible positions of adjustment, and the indexable inserts of a group having at least two working edges each, one of these edges being always in the effective and at least one other edge being in the ineffective position, depending on the position of the indexable inserts in the associated insert seats. The indexable inserts of a group assume identical positions of adjustment in which defined working edges of every indexable insert of a group have the same orientation in the associated insert seat, the working edges of the indexable inserts of a group being cut to a nominal size in all common positions of adjustment. | 07-22-2010 |
20110116877 | ROTATING CUTTING TOOL WITH SUPPORT ELEMENT - The invention relates to a rotating cutting tool, in particular a boring tool for use in machine tools. The cutting tool comprises at least one cutting insert, designed as an indexable insert, that has an active main blade located near a corner of the insert, the outer end of said blade defining a circular flight path radius (R) as the blade rotates, said blade penetrating into a work piece at a pre-determined cutting depth (t) near a pre-formed round hole. Also provided is a secondary blade that is disposed opposite to an advancing direction and that aligns with the outermost end of the main blade, the entire length of said blade having a smaller radius than the circular flight path radius (R) of the main blade, wherein a secondary blade free surface aligns with the secondary blade opposite to the direction of rotation. A unique characteristic of the invention is that the secondary blade free surface comprises a support part disposed at a distance from the secondary blade, the peripheral radius of said part being larger than the circular flight path radius R of the active main blade by an overshoot amount (Y). | 05-19-2011 |
20110123281 | MACHINE TOOL WITH ADJUSTABLE CUTTING PLATE - The invention relates to a machine tool with an adjustable cutting plate. The rotating machine tool substantially comprises a base member with a rotating axis, at least one pocket formed in the base member and at least one blade support holding a cutting plate. Two side surfaces of the blade support sit against a side support surface, respectively, said blade support side surfaces making an angle between them, and the base of the blade support sits against a base support surface of the pocket, the blade support being clamped in the pocket removably by way of a clamp element. The cutting plate protrudes over the blade support with an effective blade and over the base member outward. In order to enable a fine-adjustment of tangential cutting plates in the base member, it is proposed that the base support surface form a wedge surface that includes an acute angle together with a shift axis, said wedge surface disposed at an adjusting member that can shift relative to the base member along said shift axis, the base of said blade support, in the shape of a complementary wedge, abutting against said wedge surface. Also, the two side support surfaces form guide surfaces for the blade support that are directed substantially perpendicular relative to the shift axis of the adjusting member when said blade support makes a shifting motion by way of a shifting of the adjusting member. | 05-26-2011 |
20120200050 | JUNCTION BETWEEN TWO COMPONENTS OF A ROTATING TOOL SYSTEM - A junction between two components of a tool system, that rotates about an axis of rotation, includes a conical seat, on the first component, coaxial to the axis of rotation and which is defined by an annular front face. The second component carries a coupling having a conical surface complementary to the conical seat and an annular end face resting against the front face. A tie bolt axially projects beyond the free end of the coupling pin and engages, in a cavity adjacent to the seat. The junction also has tensioning elements that are actuated from the exterior for mutually bracing the components, which are radially guided in the first component, and which act upon the tie bolt and are functionally linked with joint actuating means for adjustment between detached and tensioned positions. The tensioning elements include ejection portions that can be fitted with a rotatably received rolling element. | 08-09-2012 |
