Definitions
- the invention relates to an indexable insert for clamping in carrier tools with an upper and a lower side, wherein on each upper and lower side between a main cutting edge and a secondary cutting edge a cutting corner is arranged with a corner radius.
- the carrier tools usually have one or more plate seats, which are provided for receiving the inserts or cutting inserts provided for this purpose.
- the indexable insert used takes over the desired material removal by penetrating the workpiece surface during a rotation and feed motion of the tool or workpiece.
- Inserts are usually made of hard materials such as ceramics, mixed ceramics, hard metals, cubic boron nitride, or polycrystalline diamond.
- indexable inserts are usually fastened due to their design with hole, recess or smooth surface Screwing or clamping by means of clamping wedge or clamping claws.
- the position in the carrier tool is defined by the setting angle of the main cutting edge, as well as the chip and inclination angle depending on the main cutting edge.
- the invention has for its object to improve an indexable insert according to the preamble of claim 1 so that the endangered during use cutting corner is reinforced, the corner radius remains substantially unchanged from an indexable insert according to the prior art. At the same time, the basic shape of the indexable insert should be maintained, whereby the existing carrier tool can be used further.
- this object is achieved in that a stabilizing facet is arranged in the cutting corner, adjacent to the corner radius.
- a stabilizing facet is arranged in the cutting corner, adjacent to the corner radius.
- this allows the corner radius to remain substantially unchanged from a prior art indexable insert.
- the basic shape of the indexable insert can be maintained, whereby the existing carrier tool can be used further.
- the facet is formed substantially rectangular and extends from an upper or lower side to the center plane of the indexable insert. As a result, the facet has a maximum size.
- the facet connects tangentially at the corner radius and is rectilinear to slightly convex, seen in relation to the center of the plate, formed and merges with tangentially subsequent transition radius in the secondary cutting edge.
- the facet viewed in the circumferential direction of the cutting plate, 0.2 mm to 2.0 mm long and serves in particular as a secondary main cutting edge.
- the facet is horizontal or inclined at +/- 5 ° to the fictitious workpiece surface.
- the facets are arranged at the cutting corners opposite the center plane of the cutting plate, with respect to a line extending perpendicularly to the upper or lower side, arranged in mirror image relative to one another.
- the number of usable cutting is significantly increased.
- the corner radius of an upper or lower side of the cutting plate passes over an inwardly inclined secondary facet into the facet of the cutting corner opposite the center plane of the cutting plate.
- the indexable insert on twice as many usable main cutting edges and minor cutting edges as cutting corners and is therefore reversible.
- the indexable insert has a triangular, square or rhombic basic shape.
- the indexable insert has a five- to octagonal basic shape.
- the transition radius of the facet to the minor cutting edge is equal to or smaller than the corner radius.
- the invention comprises an indexable insert 1 with double-sided attached
- Facet 3 for stabilizing the cutting edge 2 (see Figure 1).
- the cutting corner 2 is located in each case between the so-called main cutting edge 6 and the
- Corner radius 4 formed cutting edge 2 and thus allow reinforcement and stabilization of the cutting corners 2, without the basic shape of
- Indexable insert 1 and the actual size of the corner radius 4 and affect its functionality.
- FIG. 1 shows this particular facet 3 on a triangular-shaped indexable insert with a corner angle of 60 ° shown.
- the orientation of the facet 3 is in each case specially adapted to the subsequent installation position of the indexable insert 1 in an associated carrier tool, adapted to the common functionality and forms a secondary cutting edge in terms of cutting technology and design.
- the carrier tools used are usually face milling cutters or cutter heads. The use for turning is also conceivable with suitable carrier tools.
- FIG. 3 the schematic representation of the position of an indexable insert 1 is shown in a fictitious record seat.
- the Dash-dotted lines indicate the shape of the cutting edge of a conventional indexable insert 1 with corner radius.
- the supporting cross section q of the overhang at the cutting edge 2 inevitably becomes smaller as the corner radius 4 is reduced.
- indexable insert corner 2 the more prone the indexable insert corner 2 is against breakout or complete failure due to breakage of the overhang, which in the worst case can lead to damage of the workpiece.
- a reliable and economical processing of the component is therefore not given.
- a certain overhang, or lesser substructure of the carrier tool is necessary in order not to restrict the selection of indexable inserts on the carrier tool too far.
- a small corner radius 4 or 90 ° sidewall is not always avoidable in machining and is often desirable because some workpieces or lack of machine performance require it.
- This invention is based on the object to reinforce the endangered cutting edge 2 by attaching a facet 3, with the advantage of the actually desired small corner radius 4 of 0.2 mm to 1, 2 mm in principle at the
- This facet 3 is due to the position in the carrier tool (see Fig. 7) and the required setting angle of 90 ° asymmetric and later Direction of action horizontally attached to the cutting edge 2. Experience has shown that this asymmetry reduces the number of usable cutting corners 2 by half in the case of a negative indexable insert 1.
- the facet 3 is also mirror-inverted on the opposite, rear area of the cutting corner 2, that is, mounted on both sides. This is illustrated in Fig. 5 and further explained.
- the reference signs provided with the appendix a or b such as 3a, 3b or 4a, 4b or 6a, 6b or 7a, 7b or 8a, 8b or 9a, 9b respectively denote identical but mirror-image arranged objects.
- the facets 3 are arranged mirror-symmetrically to one another at the cutting corners opposite the center plane 12 of the cutting insert 1, with respect to a line running perpendicularly to the upper or lower side.
- the secondary facets 8a and 8b between the facets 3a / 3b and corner radii 4b / 4a are slightly angled in the transition to the opposite mirrored arrangement, protrude out of the lateral surface of the corner radii 4a / 4b and serve according to the invention the stabilizing support of the corner radii 4a / 4b. Without these special secondary facets 8, the functioning of the main cutting edges 2 and the secondary cutting edges formed by the facets 3 and the resulting double cutting edge number would not be possible.
- the actual corner radius 4, which merges into the main cutting edge 6 from the facet 3, should be mentioned, which can later also be recognized as a feature on the machined workpiece.
- the transition radius to call 9 At the opposite end of the facet 3 is still the transition radius to call 9, the tangent from the Leads out facet and with almost similar size as the corner radius 4a, 4b itself merges into the minor cutting edge 7.
- the facet 3 is usually between 0.2 mm and 2.0 mm long and ideally straight or slightly convexly curved.
- the cutting edge 2 is usually placed between the main cutting edge 6 and the minor cutting edge 7, wherein the main cutting edge and the minor cutting edge are at a defined angle to one another.
- this angle is 120 °.
- z As rhombic and square shapes are mentioned here, the inscribed angle is 35 °, 55 °, 75 °, 80 ° or 90 °.
- the orientation of the facet 3 is as shown in this case, for example between 89 ° and 91 ° to the main cutting edge 6th
- These facets 3 and secondary facets 8 and radii (corner radius 4 and transition radius 9, as well as the entire circumferential area of the indexable insert 1 are usually attached by hard machining, such as grinding or laser machining.) Also a direct pressing and pressing with appropriately shaped punch and Matrizen-, and injection mold tool sets, or other non-cutting or material-removing processes and subsequent sintering processes and hard machining is conceivable.
- the special feature of this described triangular indexable insert 1, with the facets 3 and secondary facets 8 according to the invention lies in the special suitability for use in milling by rotating carrier tools. It allows z. B. by the adjustment angle ew of 90 ° of the main cutting edge 6 and suitable chip and tilt angles of 5 ° to 15 ° of the main cutting edge 6, the production of a rectangular shoulder on the machined components (see Fig. 7).
- the inventive position and length of the facet 3 achieved in the cutting corner 2, which preferably at an angle from 80 ° to 95 ° to the main cutting edge 6, the function of a secondary main cutting edge. After the cutting operation, this results in a high surface quality with low roughness depths on the plane surface of the workpiece.
- this special facet 3 can also by means of small corner radii 4 of 0.2 mm to 0.4 mm in a roughing or roughing finishing an excellent surface quality on the workpiece, with high feed values and due to the small corner radius 4 conditionally, with less effort be calculated from the machine.
- the user's desire for cost-effective inserts, with as many usable cutting edges and cutting corners as possible for machines with low power levels, can be met herewith. It can be realized by the use of this stabilizing facet 3 and the supporting secondary facets 8 with high feed values at the same time lower power consumption, a comparatively faster processing time compared to conventional indexable inserts 1 of this basic form. With comparable or even better surface quality, a more efficient and economical machining of the workpiece is possible.
- the facets 3a and 3b, the transition radii 9a and 9b and the corner radii 4a and 4b are the same size. In the figure 5 the surfaces are distorted by the perspective view.
- WO 03/013770 A1 shows an insert with a clamping recess, which is circular and has a spherical or circular elevation in the middle.
