    • A cutting tool, comprising a body which has a seat for a cutting insert (5) in a forward part and a channel (8') for the feeding of a coolant to at nozzle (12) in a rear part, the channel comprises a through bore (15) with orifices for inflow and outflow and which is mounted in a forward part (10) which is exposed towards a cutting insert seat so that a jet (33) of fluid is directed towards the area of the seat, said channel (8') opens out into a cavity (9) behind said front part (10) which communicates with the bore of the nozzle. The nozzle comprises a nozzle insert (14) with a rotationally symmetrical shaped enveloping surface which can be rotated round its own centre axis between different angularly rotational positions in relation to a similar rotationnally symmetrically shaped hole (20) in the front part (10) and fixable in one of these positions so that a jet of fluid (33) from the nozzle body which is eccentrically positioned in relation to the centre axis of the nozzle insert can be set up, as required, to impinge on different points of impact (T, T1).
    • 一种切削工具,包括:主体,其具有用于前部的切削刀片(5)的座和用于将冷却剂供给到后部的喷嘴(12)的通道(8'),所述通道包括 通孔(15)具有用于流入和流出的孔口,并且安装在朝向切削刀片座暴露的前部(10)中,使得流体的射流(33)被引向座椅的区域,所述通道 (8')打开到与喷嘴的孔连通的前部(10)后面的空腔(9)中。 所述喷嘴包括具有旋转对称形状的包封表面的喷嘴插件(14),所述喷嘴插件(14)可相对于所述前部(10)中的类似的旋转对称形状的孔(20)在不同的角度旋转位置之间围绕其自身的中心轴线旋转, 可固定在这些位置中的一个位置,使得可以根据需要将来自喷嘴体的相对于喷嘴插入件的中心轴线偏心定位的流体喷射流(33)设置成撞击不同的冲击点(T ,T1)。

    • A cutting tool comprises, on one hand, a front part (4) for a cutting insert (5) and, on the other hand, a rear part (6), which is detachably secured in a holder, as well as a plurality of nozzles which are supplied with high pressure cooling liquid via a duct system (21) inside the tool and of which at least a first one (13) has the purpose of spraying a jet (14) towards the area of a upper surface on the cutting insert (5) with the purpose of forming a hydraulic wedge between the upper surface of the cutting insert and a chip (17) emanating from a workpiece in order to lift and distance the chip from the cutting insert. According to the invention, a second nozzle (15) co-operates in pair with said first nozzle (13) in order to direct a second high pressure cooling liquid jet (16) towards a point at a level above the cutting insert (5) in order to impinge on the chip (17) at a distance from the cutting insert and thereby apply a mechanical force on the chip which aims to deflect the chip in an upwards/backwards direction.
    • 切削刀具一方面包括用于切削刀片(5)的前部(4),另一方面包括可拆卸地固定在保持器中的后部(6),以及多个 喷嘴,其通过工具内部的管道系统(21)供应有高压冷却液体,并且至少第一喷嘴(13)具有朝向切割处的上表面区域喷射喷流(14)的目的 插入物(5),目的是在切削刀片的上表面和从工件发出的切屑(17)之间形成液压楔,以便将切屑从切削刀片上提起并且将其远离。 根据本发明,第二喷嘴(15)与所述第一喷嘴(13)成对配合以便将第二高压冷却液体射流(16)朝向切削刀片(5)上方的高度的点引导, 以便在离开切削刀片一定距离处撞击在芯片(17)上,并由此在芯片上施加机械力,旨在使芯片在向上/向后方向上偏转。
