20080298914 | Actuated material removal tool - Material removal tool with a translating bar having an actuation surface shaped as a cone or frustum, wherein an axial position of the cone or frustum along a length of the translating bar corresponds to a position of a push rod in operable contact with a first flexibly mounted cartridge on which a cutting insert is mounted is disclosed. The translating bar is actuated between a first and second position to place different combinations of flexibly mounted cutting inserts and fixedly mounted cutting inserts in a radially outermost position. The material removal tool optionally includes a support for the translating bar to reduce radial variation during machining operations. Various combinations of flexibly mounted cutting inserts and fixedly mounted cutting inserts are disclosed along with various methods for removing material using the disclosed material removal tool | 12-04-2008 |
20100014933 | BACKBORE TOOL WITH COOLANT ACTUATION - A material removal tool with a cutting insert mounted in the seating pocket is disclosed. The translating bar is operably connected to the at least one radially pivotable arm by a mechanical linkage and translates under fluid pressure applied to one side of a piston head by an actuating fluid, where the actuating fluid is also coolant for the material removal tool. With the translating bar in a first position, the radially outermost edge of the cutting insert is radially inward from the first active volume, and with the translating bar in a second position, the radially outermost portion of the cutting insert is radially outward from the first active volume and the axially rearmost portion of the cutting insert is rearward of an axially rearmost portion of the arm. A method of removing material from a workpiece with the material removal tool, such as by backboring, is also disclosed. | 01-21-2010 |
20100054879 | MATERIAL REMOVAL TOOL WITH ACTUATED GUIDE PADS - A material removal tool including a housing body having an active portion, at least one seating surface for a cutting insert operatively positioned on the active portion, and a guide pad positioned in a cavity in a circumferential surface of the active portion is disclosed. The guide pad is radially adjustable between a first radial position and a second radial position by a differential pressure across the guide pad. The differential pressure is created by an actuation fluid supplied to one side of the guide pad. A method for removing material from a workpiece with the rotating material removal tool is also disclosed. | 03-04-2010 |
20100183382 | MATERIAL REMOVAL TOOL WITH NOISE REDUCTION FEATURES - Rotary material removal tool mounted to a shaft for rotational motion includes a body and a plurality of radially extending arms. Each arm includes a radially outward peripheral edge, and, relative to a direction of rotational motion of the body, a leading side and a trailing side. Radially outward peripheral edges include a cutting insert mounting structure that projects axially below a bottom side of the body. The rotary material removal tool includes at least one of the following features to reduce measured air pressure (P | 07-22-2010 |

20130294853 | Cartridge with Fine Adjustment Means - Cartridge for supporting at least one cutting insert and for being received on a tool body is disclosed. At least a first portion of the cartridge may be stationary mounted and the cartridge includes at least one pocket for receiving a cutting element. A coarse and a fine adjustment means are provided by means of which at least a second portion of the cartridge including the pocket may be moved with respect to the tool body and wherein the coarse and the fine adjustment means are merely provided at the cartridge | 11-07-2013 |
20140050544 | Device and Method for Generating Microstructures in Cylindrical Surfaces - Tool and method for generating microstructures within cylindrical surfaces with a higher degree of efficiency, thereby allowing to provide cylindrical surfaces with a corresponding microstructure in much shorter cycle time. Cutting elements of the tool are arranged within seats to be radially displaceable in said seats during rotation of said tool body. The cutting elements are radially displaceable at least between two different radial positions, namely a radially retracted and a radially extended position. The cutting elements can be evenly distributed about the circumference of the tool at the same radial distance such that the tips of the cutting teeth and also the seats define a common cylindrical envelope surface the axis of which coincides with the axis of the tool body. | 02-20-2014 |
20140186128 | Cubic Cutting Insert for Boring or Plunging - Cutting insert comprising a cuboid body having a substantially square top face and bottom face, said top face and bottom face connected by four peripheral adjoining side surfaces, wherein at least two cutting edges are formed at the transition of the top face to at least two side surfaces, that cutting edges defining a plane of the top face. To provide a cutting insert and a corresponding tool suited to produce valve seat surfaces with high precision but still having a rather simple construction and being precisely mountable with ease and less efforts of adjustment, the plane defined by the top face cutting edges of the cutting insert has maximum dimensions of 7 mm×7 mm, the bottom face has a supporting surface formed exactly parallel to the plane defined by the top face cutting edges by means of grinding within a tolerance of less than 5 angular minutes. | 07-03-2014 |
