Definitions

  • the present invention relates to an arrangement for the fastening of cutting inserts on cutting insert holders for the cutting machining of primarily metals, and cutting inserts intended to be fastened in such an arrangement.
  • Different cutting inserts and indexable cutting inserts are fastened in tool holders in several different, known ways.
  • the most usually occurring is that the cutting insert has a through central hole and the insert seat in the holder has a threaded hole.
  • a locking screw is introduced into the central hole ofthe insert and is tightened in the hole ofthe holder by a suitable torque, and frequently also a shim plate with a central hole is placed between the cutting insert and a bottom support surface.
  • the insert seat also comprises two mutually substantially perpendicular abutment surfaces, or three abutment points, for bearing against two ofthe edge surfaces ofthe cutting insert.
  • the disadvantage of that construction is that a certain play of the insert may easily arise after a period of use.
  • a further disadvantage is that one may easily happen to tighten the screw too strongly, whereby it may be damaged or even broken.
  • insert holders have a clamp or similar fastening arrangement which presses upon the upper side ofthe insert in order to clamp it in the insert seat.
  • the pressing force of the clamp may be regulated by a screw.
  • Such constructions may for instance be used for clamping cutting inserts without any central hole, as is the case for parting inserts for example.
  • a further drawback is that, even if the cutting insert has been secured in a direction perpendicular to the serrations, a vertical play may arise just as easily as in the case of two wholly planar bearing abutment surfaces, in particular during machining operations prone to vibrations.
  • a primary object ofthe present invention is to provide an arrangement for the fastening of cutting inserts, which arrangement makes possible a very strong and very stable fastening ofthe insert, without the slightest risk of moving the insert.
  • Another object ofthe present invention is to provide an arrangement that enables a stable and strong fastening o the insert in at least two. preferably three indexed positions.
  • Still another object ofthe present invention is to provide a strong, pJay-free and stable fastening ofthe insert without any costly and time-consuming grinding.
  • Yet another object ofthe present invention is to provide a cutting insert which may be directly pressed and that allows for a very strong and stable fastening in two or more insert positions.
  • a still further object ofthe present invention is to avoid the necessity of abutment surfaces or abutment points in the insert seat, which require a high dimension accuracy.
  • Figure 1 shows an insert fastening arrangement according to the invention. in the form of an exploded view in perspective, obliquely from above.
  • Figure 2 shows a bottom plan view ofthe cutting insert of Figure 1.
  • Figure 3 shows an exploded view of another embodiment ofthe invention, in perspective obliquely from above.
  • Figure 4 shows an exploded view of still another embodiment ofthe invention, in perspective obliquely from above.
  • Figure 5 shows an exploded view of still another embodiment ofthe invention, in perspective obliquely from above.
  • Figure 6 shows a cross-section of a first basic embodiment ofthe invention.
  • Figure 7 shows a cross-section of a second basic embodiment ofthe invention.
  • Fig 1 shows a boring bar or insert holder 1 whose shaft part is not essential for the present invention.
  • the front part of the holder comprises a base surface 2, on which are arranged ribs 3 which are intended to fit into grooves 4 on the bottom side of a shim 5.
  • the ribs 3 and the grooves 4 may suitably be made in accordance with Swedish patent application 9401429-7 (corresponds to WO 95/29026). which makes it possible to dispense with rear abutment surfaces or points in the insert seat.
  • this insert seat does not require any abutment surfaces, which considerably simplifies the manufacturing ofthe insert seat.
  • the shim 5 is fastened on the base surface 2 by a shim screw 6 that has an outer thread 6A threaded into the hole 9, whereby the bottom side ofthe head ofthe shim screw presses against the abutment surface 7.
  • the boundary layer or interface comprising the ribs 3 and the grooves 4 is not the boundary layer related to this invention.
  • the boundary layer that is essential for the invention is the one between the shim 5 and a cutting insert 10, which boundary layer will now be further described.
  • a cutting insert 10 in this case a triangular, single-sided insert for threading, by means of a locking screw 1 1. which is tightened into the inner thread 6B ofthe shim screw 6.
  • the insert 10 is made of coated or uncoated cemented carbide, although other materials may also occur, e.g., different ceramic materials.
  • the bottom side of the cutting insert 10 has grooves 12 in all three corners, which may be seen more clearly in Fig 2. One set of such, substantially parallel grooves is brought into engagement with a set of corresponding ribs 13 on the top side 15 of the shim.
  • ribs are formed having substantially planar surfaces or cams 14, which are intended to bear against the top side 15 of a non-ribbed portion ofthe shim in a way that may be seen more clearly at the left side in Fig 6 and 7.
  • Fig 6 and 7 show the principle ofthe present invention, viz., that the ribs 16 with their planar cams 14 fulfil a double function.
  • the ribs 16 serve for wedging and fastening between the ribs 13 ofthe shim (or ofthe insert holder, if no shim is used), and on the other hand the planar cams 14 of the ribs 16 function as bearing surfaces which bear against planar non-ribbed portions ofthe top surface 15 ofthe shim (or ofthe insert holder, if no shim is used).
  • the planar cams 14 of the ribs 16 function as bearing surfaces which bear against planar non-ribbed portions ofthe top surface 15 ofthe shim (or ofthe insert holder, if no shim is used).
  • the flange (side) surfaces 13A ofthe ribs 13 bear against the flange (side) surfaces 12A ofthe grooves 12. Contrary thereto, the tops 13B, 14 of the ribs 13 and 16. respectively, are not intended to reach the corresponding groove bottom.
  • the cutting insert 10 according to Fig 6 is provided with a central, more deeply recessed middle portion 17, which is not in contact with the shim.
  • FIG 7 Another embodiment principle is shown in Fig 7.
  • the bottom surface ofthe insert is planar and in the same level as the planar rib cams 14.
  • the shim 5 has been provided with a deeper middle portion 18, in order to obtain the statically well-defined abutment of three points or regions at the three corners ofthe insert.
  • Fig 3 shows another embodiment according to the present invention. Also this one has a boring bar 1 with a front base surface 2' and ribs 3' which cooperate with grooves 4' on the bottom side of the shim 5'.
  • an indexable cutting insert 10' is fastened on the shim 5'.
  • the indexable insert 10' is double-sided and is on both sides provided with grooves 12' and ribs 16', the latter having planar cams 14".
  • the opposite side ofthe insert is provided with similar serrated portions as the visible top surface.
  • the ribs 16' engage between ribs 13' on the top side 15' of the shim, in order to stay and stabilize the operative cutting corner 19.
  • a portion 20 on the top side ofthe shim may be somewhat raised, in order to bear against the planar rib cams 14' ofthe insert.
  • the ribs 16' ofthe insert fulfil the double function that is characteristic ofthe invention.
  • the ribs 13 and 13' are located underneath the operative cutting corner and that is also the prefe ⁇ ed embodiment.
  • the invention may also be applied to round cutting inserts.
  • the shim 5" bears against the boring bar 1" in the same way as in Fig 1 and 3.
  • the cutting insert 10" is double-sided, wherefore the bottom side ofthe insert is basically identical with the visible top side.
  • a number of radial grooves 12 " are a ⁇ anged on the two opposed main sides ofthe insert. For instance between 2 and 5. suitably 3 as shown in Fig 4, of those grooves enclose an equally large number of ribs 13' * on the top side 15" ofthe shim 5' " . whereby abutment is accomplished in the above described way on the flank surfaces ofthe grooves and the ribs, as shown in Fig 6 and 7.
  • abutment between the insert and the shim may per se take place over the whole surface 15", but preferably this surface is provided with two protruding bearing surfaces 21. which are intended to bear against co ⁇ esponding sector-shaped, planar surface portions 14" on the round insert.
  • Fig 5 shows an embodiment that is analogous to the one in Fig 4. The difference is that it lacks a shim.
  • the ribs 13" and the protrusions 21 are a ⁇ anged directly on the boring bar.
  • a new section ofthe cutting edge 22 may be indexed by untightening the locking screw and turning the round insert according to Fig 4 and 5 at lest by a twelfth ofa revolution, since the grooves 12" divide the main surfaces ofthe insert into twelve sectors. Thereafter, the locking screw is tightened again.
  • fastening anangement according to the invention is also suitable for milling and drilling.
