Definitions

  • This invention relates to a cutting insert intended for chip removing machining, which is delimited by a top side, a bottom side and a number of side surfaces extending there between, and which has at least one cutting edge between said top side and a side surface serving as a flank, grooves which are mutually separated and open upwards, are provided in said top side, in connection with the cutting edge, for feeding cooling liquid in the direction towards the cutting edge.
  • the material of the workpiece vary between tenths of a millimetre to a few millimetres backwards from a shear zone which is near the cutting edge. In doing so, the hot material is strongly adhered in a thin layer, above which the proper cutting of the chip takes place by shearing in a secondary shear zone (frequently designated weld zone).
  • a so-called friction zone follows, along which the chip is in forceful frictional contact with the cutting insert before leaving this.
  • some sort of chip deflector is provided; e.g. in the form of bumps or projections on the top side of the actual cutting insert and/or in the form of specific bodies on the tool, in particular clamps for the retention of the cutting insert.
  • the modern high-pressure cooling-liquid technology aims at introducing the cooling-liquid jet into the substantially wedge-shaped space provided between the bottom side of the chip and the top side of the cutting insert at the point where the chip is initially separated from the cutting insert.
  • the idea being to form a so called hydraulic wedge between the chip and the top side of the cutting insert, and that said wedge should contribute to "break out” the chip and, as far as possible, reduce the extent of the contact length of the chip along the cutting insert.
  • a fundamental aim with the introduction of high-pressure cooling liquid between the chip and the cutting insert is, of course, also to cool these as effectively as possible.
  • the attempts to improve the cooling and the flow of the chip away from conventional cutting insert carried out hitherto have not been entirely successful.
  • a primary object of the invention is, therefore, to provide a cutting insert which permits access of high- pressure liquid jets to the area below the zone along which the chip is separated from the cutting insert, at the same time as the chip should be broken out from the top side of the cutting insert as effectively as possible.
  • Another object is to provide a cutting insert that guarantees the intended improvement of the cooling and the removal of chips by means of simple and thereby inexpensive means, more precisely by providing the cutting insert with a new geometric shape.
  • at least the primary object is attained by the features defined in the characterizing part of claim 1.
  • the preferred embodiments of the cutting insert according to the invention are further defined in the dependent claims.
  • a cutting insert specially constructed for forming threads is previously known through DE 3 740 814, the said insert has a number of grooves for feeding cooling liquid in the direction towards the cutting edge of the cutting insert in the top side thereof. More precisely, three comparatively wide grooves are recessed in the top side of the cutting insert and arranged to co-operate with a separate clamp having the purpose of holding the cutting insert in the appurtenant seat and, at the same time, serving as a chip deflector.
  • the grooves together with the bottom side of the clamp therefore, define ducts to which cooling liquid is fed from a central main duct in the frame of the cutting tool. This implies, among other things, that the cooling liquid may not be fed in the form of jets with high pressure. Furthermore, this way of feeding the cooling liquid is limited to only the cutting inserts being held by clamps.
  • FIG. 1 a perspective view of a first, simple embodiment of a cutting insert according to the invention
  • Fig 2 a planar view from above of the cutting insert according to fig 1 ,
  • Fig 4 a planar view corresponding to fig 2 of a cutting insert according to a second, alternative embodiment of the cutting insert
  • Fig 5 a planar view showing a third embodiment of the cutting insert according to the invention
  • Fig 8 an enlarged, detailed view showing an individual groove in cross-section
  • Fig 9 an enlarged, detailed section showing a cutting insert according to fig 5-8 during the turning of a workpiece
  • Fig 10 a planar view showing a fourth, alternative embodiment of the cutting inserts.
  • a cutting insert 1 is shown, which is delimited by a top side 2, a bottom side 3 as well as a number of side surfaces 4 extending therebetween In the example shown, the number of side surfaces is four.
  • the straight cutting edge portion 5 transforms into a rounded cutting edge portion 5'.
  • a number of mutually separated grooves 8, are provided in connection with the cutting edge 5 and said grooves open upwards in the top side of the cutting insert.
  • the projections 9 are arranged between adjacent grooves 8 in a manner which is characteristic for the invention, these projections protrude from the top side of the cutting insert and together form a chip deflector for each chip cut loose by the cutting edge.
  • the individual grooves extend from an area close to the central hole 6, all the way to the flank 4.
  • each individual groove opens up into the flank 4.
  • the embodiment according to fig 4 differs from the embodiment according to fig 1 -3 only in the fact that sets of grooves 8 are arranged along each one of the four side cutting edges or cutting edges of the cutting insert.
  • the cutting insert according to fig 4 constitutes an indexable insert.
  • figs 5-8 illustrate a third, alternative embodiment of the cutting insert according to the invention.
  • the only fundamental difference between this cutting insert and the cutting insert being visualised in fig 1 -3 is that the individual grooves 8 end at a certain distance from the appurtenant cutting edge 5. Accordingly, in this case, the cutting edge 5 extends unbroken between two corners of the cutting insert.
  • the individual groove 8 has an upwardly diverging cross-sectional shape. More precisely, the groove is delimited by two oblique side walls 10, 10', which at the bottom transform into a mutual bottom surface 1 1 having a rounded shape.
  • the individual groove should have a depth that is larger than the width thereof on a level with the top surface of the cutting insert 2. In practice, on a level with the top surface 2, the groove can have a width in the range of 0,2-0,4 mm, whilst the depth - calculated from the bottom surface 11 to the level of the top surface 2 -can be in the range of 0,4-0,6 mm.
  • numeral 12 designates a land between two adjacent grooves 8.
  • the width of this land portion should be at least twice as large as the width of the individual groove 8 on a level with the land portion. In practice, therefore, the width of the land portion amounts to 0,8-1,2 mm or more.
  • the shape of the individual chip deflector projection 9 should be generally rounded. Thus, as may be seen in fig 6, a convexly rounded crown surface transforms into the top surface 2 and a land portion 12, respectively, via concavely rounded transition surfaces. Laterally, the individual projection may advantageously be delimited by extensions of the cutting edge-shaped, diverging side surfaces 10, 10', defining the groove 8.
  • fig 9 How a rotating workpiece 14 is submitted to a turning operation by means of the cutting insert 1 together with the appurtenant tool 7 is schematically shown in fig 9.
  • the cutting insert cuts a chip designated by 15.
  • the separation of this chip 15 from the workpiece 14 is initiated in a primary shear zone, which is outlined in fig 9 by means of the dotted line 16.
  • a secondary shear zone In a portion of the chip, designated by 17, there is a secondary shear zone, along which the chip finally is separated.
  • the material adheres to the top side of the cutting insert in a thin layer below this shear zone, and a friction zone then follows this before the chip finally leaves the cutting insert.
  • the number 18 designates a cooling-liquid jet which is ejected at high pressure from a nozzle (not shown) included in the tool and directed against the area between the under side of the chip 15 and the top side of the cutting insert.
  • the pressure in the cooling liquid which leaves the nozzle can to advantage be within the range of 250-1 000 bar, or even more.
  • the cooling-liquid jet 18 can be led into the space below the chip 15. More precisely, a feeding of the cooling liquid to the immediate vicinity of the cutting edge takes place in the form of a number of partial flows in each of the grooves 8. This implies that the jet operating with high pressure is given improved capability to affect the chip mechanically, inasmuch as this in at least the friction zone is broken up at a steeper angle to the top side of the cutting insert than with previously known technology. This means that the contact length of the chip, from the cutting edge to the point when it separates from the cutting insert, may be reduced. At the same time, the steeper the breaking angle of the chip the easier it is to break it into smaller pieces.
  • the embodiments according to fig 1 and 4 have the advantage that the cooling liquid supplied can pass out through the ends of the grooves 8, which open, into the flank 4.
