Definitions
- the invention relates to a polygonal indexable insert having a flat bearing surface and cutting edges on the upper side, which are alternately pointed by two or more cutting corners with consecutively connecting and blunt corner angles of less than 89 ° and more than 91 °, the cutting edges facing flat bearing surface such a straight or curved run that the thickness d of the insert in the cutting corners with acute angle is greater than the thickness d 'in the cutting corners with obtuse angle.
- Such a rhomboid or rhomboid-shaped indexable insert is described in EP 0 642 859 A.
- the cutting edges pass directly into a rake surface which first drops and then rises relative to the support surface, forming a wavy intersection curve with a central central region of the indexable insert.
- the central central region is flat, executed parallel to the support surface and is located above the highest point of the cutting edges. In this way, especially in the cutting edge area with the lower indexable insert thickness, a sharply increasing chipboard level results.
- the object of the present invention is therefore to provide an indexable insert of the type mentioned, which can also be used with large feeds, without causing premature damage to the cutting edges and reduced surface finishes.
- Cutting corners are each provided with a chamfer, which has a maximum angular deviation of 10 ° and a width between 0.5% and 3% of the length of the associated cutting edge with respect to the support surface.
- This design contributes to the fact that even at high feeds during drilling and turning, the cutting forces remain small and a good chip breaking is achieved, so that a high dimensional stability and good surface quality of the machined workpieces is achieved.
- the imaginary connecting line between the intersection of the intersection curve with the bisector of the cutting corner at an acute angle and the intersection of the bisector of the cutting edge with obtuse angle with the lowest point of the rake face, with respect to the associated cutting edge when it is rectilinear in a plane perpendicular to the support surface, or with respect to an imaginary connecting line between the starting and ending points of the associated cutting edge, when curved in the plane perpendicular to the support surface runs, has a maximum angular deviation of 5 ° in this plane, also occur low chip forces and it is achieved a good chip deformation.
- the central portion has a central, planar central area, significant improvements in the manufacture of the indexable insert result.
- knob-shaped elevations are arranged in the region of the cutting corner at an acute angle, in the direction of the bisector following the middle section, a good chip breaking behavior is achieved at smaller cutting depths.
- Figure 1 shows an indexable insert according to the invention in side view Figure 2
- the indexable insert of Figure 1 in plan view Figure 3 shows the variant of an indexable insert according to the invention in side view
- FIG. 4 shows the indexable insert according to FIG. 1 and FIG. 2 in an oblique view with surface lines
- FIG. 5 shows a further variant of a device according to the invention
- Figure 6 shows a third variant of an indexable insert according to the invention in plan view
- FIGS. 1, 2 and 4 show a rhombus-shaped indexable insert according to the invention with four equally long, substantially straight cutting edges -2- and one planar bearing surface -1.
- the cutting edges -2- go in the corners of the indexable insert, in two opposite circular arc cutting corners -3- with acute corner angles of 88 ° and in two opposite circular arc cutting corners -4- with each obtuse corner angles of 92 °, about.
- the indexable insert has its largest thickness d
- the cutting corners -4- with obtuse converging cutting edges -2- has a smaller thickness d 1 .
- the cutting edges -2- extend in a plane perpendicular to the support surface -1 - outside the cutting corners -3-, -4- accordingly as an obliquely sloping straight line.
- the cutting edges -2- are provided outside of the cutting corners -3-, -4- with chamfers -5-, which extend in relation to the support surface -1 - sloping inclined at an angle of 5 °.
- the indexable insert has a with respect to the support surface -1 - first sloping and then with a back portion -7- rising rake surface -6-.
- the rising spine portion -7- of the rake face -6- forms an intersecting curve -8- with a central portion -18- of the indexable insert.
- This intersecting curve -8- runs in such a way that in the respective regions of the cutting corners -3- at the intersection point -9- with the associated bisector -10- has a distance a from the starting point -15- of the associated cutting edge -2-.
- the intersection curve -8- from the end point -16- of the associated cutting edge -4- each has a distance b which is greater than the distance a is.
- the respective points of intersection -9- lie opposite the corresponding starting points -15- of the cutting edges -2- either at the same level or up to a maximum of 6% of the length of the cutting edge -2- lower.
- the indexable insert has a central hole -24-, which tapers conically towards the central region -18-.
- the central region -18- extends away from the intersection curve -8-, towards the central hole -24-, rising slightly and discharging into a concentric with the conical region of the central hole -4- extending flat collar surface -25-, which parallel to the support surface -1 - runs.
- the intersecting curve -8-along the respective cutting edge -2- wavy Seen from the center hole -24- to the respective cutting edge -2-, the intersecting curve -8-along the respective cutting edge -2- wavy, wherein in the region of the cutting edge center a wave crest -20- and to the areas of the cutting corners -3- and - 4-, troughs -21 - and -22- are provided. In the areas of the cutting corners -3-, immediately following the middle region -18-, a nub-shaped elevation -19- is arranged, which extends directly to the respective circular cutting corner -3-.
- FIG. 5 shows the variant of a rhombus-shaped indexable insert according to the invention, in which the intersecting curve -8- is not wavy with respect to the associated cutting edge -2- continuously curved.
- Cutting corner -3- no raised knob -19- provided, but there reaches the middle range -18- even to the immediate close to the circular cutting corner -3-.
- FIG. 6 shows the variant of an indexable insert according to the invention in hexagonal basic form, in which the intersecting curve -8- again in a wave-like manner relative to the associated cutting edge -2-, but in such a way that a wave trough is present in the region of the respective cutting corner -3 , while at the respective cutting corner -4- is the highest point of a wave crest.
