    摘要： A tool for metal cutting comprising a first part, one or several cutting means (8) being detachably mountable on said first part, and an axially opposite male part (9) that is applicable in a seat in a clamping unit, through which a cooling medium for said cutting means (8) may be fed, via a channel, to at least one nozzle (28), through which the cooling medium is allowed to be ejected in direction towards said cutting means. The cooling medium channel communicates with an essentially radially directed hole (15) that emerges in an envelope surface (23) of the male part (9), said hole (15) due to its radial location guaranteeing that cooling medium of extra ordinary high pressure is allowed to be fed in without applying any axial forces worth mention to the tool.

    摘要： A toolholder (10) for use in a metalworking operation, with a body (105) extending along a longitudinal axis (110) and a recess (120) extending within the first end (115) of the body. Adjacent an insert pocket (125) adapted to receive a cutting insert (130) in the recess (120) is at least one wall (135) with a portion having a surface with multiple interruptions (142) to form a chip ejection segment (145). The chip ejection segment (145) may be an integral part of the toolholder body (105) or may be a discrete piece removably attached to the toolholder body. A method of imparting to a toolholder (100) such a chip ejection segment (145) is also disclosed.

    摘要： A metal cutting tool assembly (1) having an automatically adjustable chipbreaker (23) is provided that comprises a cutting insert (11) for cutting a relatively rotating workpiece, a holder (3) for holding the insert (11), an insert driver (5) for applying a cutting force between the insert (11) and the workpiece, a chipbreaker (23) having a surface (27) that is effective in breaking chips (55, 56) of different thicknesses when positioned at different distances from the cutting edge (19) of the insert (11), and a mounting mechanism (30) for movably mounting the chipbreaker (23) onto the holder (3). The mounting mechanism (30) includes a spring (50) for automatically adjusting the distance between the chipbreaking surface (27) of the chipbreaker (23) and the cutting edge (19) of the insert (11) in response to the forces applied to the chipbreaker (23) by the metal chips (55, 56) that result from the cutting operation. The mounting mechanism (30) may allow the chipbreaker (23) to either slidably reciprocate on the holder (3) toward and away from the cutting edge (19), or to pivotally move with respect to the cutting edge (19). In both cases, the deflection of the spring (50) is proportional to the thickness of the metal chips (55, 56) engaging the chipbreaking surface (27), which in turn automatically provides the appropriate chipbreaking geometry. The inventive tool assembly allows the same chipbreaker (23) to effectively break chips (55, 56) of widely varying thicknesses which are created when the cutting insert (11) is used to make a variety of different types of cuts in a machining operation.

    摘要： The present invention relates to a cutting insert (3) for chip removing machining, the cutting insert (3) comprising an elongate centre part (7), cutting edges (5A, 5B) being arranged at the opposite ends of the centre part (7), the cutting insert (3) being provided with engagement members(10) along two longitudinal, opposite sides, the cutting edges (5A, 5B) forming, in an end view of the cutting insert (3),a mutual angle(α). The invention also relates to a tool, which comprises a cutting insert according to the present invention. Characteristic of the cutting insert according to the present invention is that the rake faces (9A or 9B) associated with the respective cutting edge (5A or 5B) are facing the opposite direction in the vertical direction (H)of the cutting insert (3), and that the mutual angle (α) is in the interval of 10°
