Abstract: 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.

Abstract: An adjustable cartridge to be mounted in the end of a boring bar, the cartridge including an anvil rotatably affixed to said boring bar, said anvil including a pocket into which a indexable insert is affixed. The anvil is secured in an axially oriented slot which includes an arcuate seating face which includes a key and key way slot. Rotation of the anvil within the slot effects radial adjustment of the insert a key pin serves to pivotally secure the cartridge within the pocket. In addition, the level or back taper of the insert can be adjusted.

Abstract: A boring head having a diametrical bore adjacent the working end thereof for insertion and removal of two or more interchangeable cutter holders. The cutter holders are restrained against rotational movement within the bore but not axial movement, whereby rotation of a first drive member having threaded engagement with an internally threaded longitudinal bore in the cutter holder will cause radial adjustment of the cutter holder relative to the boring head. Rotation of the first device member is accomplished by rotation of a second drive member having a gear drive connection with the first drive member. A first micrometer dial on the outer end of the first drive member provides for rough orientation of the cutter holder during such radial adjustment thereof, whereas a second micrometer dial on the outer end of the second drive member provides for extremely precise measurements of such radial adjustment.

Abstract: A hollow housing (20) slidingly retains an extendable body (22) through an open end allowing forward and aft movement. A rotatable tool holding head (34) is adjustably connected to the body (22) and is free to rotate up to 180 degrees. Extendable adjustment in the form of a threaded shaft (44) and handwheel (46) provide the manual expansion movement by rotation of the wheel (46) located on the opposite end as the body (22). Radial movement is afforded by a similar handwheel (50) attached to the head (34) through a drive shaft (48). A slidable end (36) is attached to the head (34) and contains a removable cutting tool (38) that rotatably cuts away material from a rotated workpiece. In a variation of the body (20) an angular shape is added with or without a mounting slot. Also, a pair of servo motors (62) and (64) may replace the handwheels for electromechanical adjustment of the device incorporating another embodiment.

Abstract: A linearly and angularly adjustable holder for a cutting tool having primary and secondary cutting edges includes a basic element, a receptacle element for the cutting tool rotatably mounted on the basic element, and a setting element slidably mounted on the basic element.The receptacle element is mounted on the basic element so as to be pivotal about the point of intersection of the primary and secondary cutting edges of the cutting bit. An adjustment screw 50 whose threaded portion is seated in the basic element and whose head engages a recess in the receptacle element serves to perform the angular adjustment. The linear adjustment is accomplished with the aid of a double threaded adjustment screw which connects a wedge and the basic element and which slidably engages the setting member to control the length of the holder.

Abstract: The head has a transverse groove in its leading face in which two cutting blade holders with interchangeable cutting blades are clamped by means of a set screw. After loosening of the set screw, the cutting blade holders can be radially and axially adjusted by means of adjusting screws. This enables precise positioning of the cutting blades, to eliminate unequal chip formation, and rough operation due to unequal loading of the blades.
