Embodiment Construction
[0050] In the figures, the same elements are denoted by the same reference numerals.
[0051] Figure 1 to Figure 6 An embodiment of a turning tool 1 according to the disclosure is shown. The turning tool 1 allows optimized cooling of the cutting insert 2 during external turning as well as during internal turning. The basic body of the turning tool 1 is formed by a tool body 4 carrying an insert seat 3 for receiving a cutting insert 2 . In order to mount the cutting insert 2 in the insert seat 3 of the tool body 4, the turning tool 1 also has a clamp 5 which is screwed onto the tool body 4 by means of a mounting screw 6 passing through a hole in the clamp 5 and engages in a threaded hole in the tool body 4. Apart from the actual clamping function, the holder 5 comprises a cooling duct with two outlets 7a, 7b to spray a jet of cooling fluid from the holder 5 onto the chip surface 8 of the cutting insert 2 .
[0052] The cutting insert 2 in the illustrated embodiment has a r...

The present disclosure relates to a turning tool comprising a tool body having an insert seat to accommodate a cutting insert and a mounting means for mounting the cutting insert at the tool body, a guiding block movably mounted between a first position and a second position at the tool body, and a fluid passage with an inlet end and at least one outlet which is arranged to guide a cooling fluid from the inlet end to the at least one outlet, wherein the at least one outlet is arranged to eject a jet of the cooling fluid onto a clearance surface associated with the cutting edge at the cutting insert, wherein a first section of the fluid passage extends through the tool body, wherein a second section of the fluid passage extends through the guiding block, and wherein the at least one outlet forms an end of the second section of the fluid passage in the guiding block. It is an aspect of the present disclosure to provide a turning tool allowing an optimized cooling of a clearance surface of the cutting insert during an external turning operation while at the same time allowing internal turning with the same turning tool. According to the present disclosure this aspect is addressed by a turning tool as outlined above wherein at least the tool body or the guiding block is arranged such that when the guiding block is in the first position the jet of cooling fluid is ejected along a first line and such that when the guiding block is in the second position the jet of cooling fluid is ejected along a second line, wherein the first line and the second line have different orientations and intersect each other at a position in a downstream direction from the outlet.
Description
technical field [0001] The present disclosure relates to a turning tool comprising: a tool body having an insert seat for receiving a cutting insert having a cutting edge and a clearance surface associated with the cutting edge; a guide block, The guide block is mounted on the tool body and is movable between a first position and a second position; and a fluid channel having an inlet end and at least one outlet arranged to channel cooling fluid from the inlet end Leading to the at least one outlet, wherein when the cutting insert is received on the insert seat, the at least one outlet is arranged to spray a jet of cooling fluid towards the region where the clearance surface is located, wherein the first section of the fluid channel extends through A cutter body, wherein the second section of the fluid channel extends through the guide block, and wherein the at least one outlet forms an end of the second section of the fluid channel in the guide block.
