摘要:
An adjustable tool holder having a block portion adapted for mounting on a boring bar or the like. Tool-holding means is adjustably attached to the block portion and movable with respect thereto to vary the relative spacing between the cutting edge of a tool carried thereby and the boring bar to vary the bore diameter. Adjustment means carried in the tool holder is cooperable with the block and accessible from an outer edge of the tool holder so that adjustment may be made without removal of tool holder from the boring bar.

A milling cutter body of basically cylindrical shape has a plurality of grooves of a circular cross-section each of which intersects the envelope surface of the cutter body. These grooves receive insert-carrying cartridges of a corresponding circular cross-section. Each cartridge is adjustably rotatable about an axis of its respective groove and is also axially adjustable along such axis. The groove axes are not parallel to the axis of rotation of the cutter body but are inclined to it. A precise positioning of the parallel land angle of the cutting edges is obtained by turning the cartridge about the groove axis and/or axially adjusting the cart ridge along that axis.

This invention relates to face milling tools used to create a generally planar/face surface on a workpiece. Embodiments of this invention allow more teeth per unit tool diameter for certain types of cutting insert mounting styles and generally for larger cutting inserts. In particular, this invention allows the aforementioned while keeping manufacturing cost lower than it could be with some other designs, mainly by allowing manufacture of the face mill using larger tools that approach the face mill from mainly or exclusively the axial direction, thus requiring the equipment used to manufacture the cutter body to be a lower cost three-axis machine as compared to four- and five-axis machines that may be otherwise needed. Embodiments of the invention also permit adjustment of the axial positions of multiple cutting inserts and their support pockets by way of adjustment in the face mill manufacturing process. Other embodiments allow the adjustment to be made by the end-user in the field on a case-by-case basis after manufacture of the face mill is complete.

In a cutting tool for chip removing machining a holder for a cutter has a body received therein and movable with surfaces to bear against the cutter for defining the position of the cutter in the direction of an intended axis of rotation of the holder as well as a screw which may be screwed in a threaded bore in the holder. Spring members are arranged to act between the holder and the body for biasing the body against said screw portions.

摘要:
A tool for machining workpieces, having at least one cutting edge which is fastened to a main body of the tool. A respective deburring device removes the burrs produced by each cutting edge during machining. The deburring device is supported at the main body near the cutting edge and is movable by an actuatable piston between a retracted storage position in the tool body and an extended active position out of the tool body for deburring after surface machining.
