Definitions
- the invention relates to a processing disc for cutting and removing according to the preamble of claim 1 and a method for its production.
- grinding disks that are made in one piece, but have a relatively short service life and have a mineral structure and remove workpieces with the formation of grinding dust. These disks are formed over the entire surface and in one piece, so that the workpiece is not visible during processing.
- Such, in particular mineral, grinding and cutting disks are usually pressed, these disks being fiber-reinforced, for example, and the mineral constituents being held in the mold by means of appropriate binders.
- cutting and grinding discs that are made up of several parts, with cutting edges mounted on the disc.
- These disks have, for example, radially outwardly projecting segments, with cutting, for example hard metal cutting, being arranged in an area in which the respective segments come into contact with a metal workpiece to be machined.
- Cutting discs of this type have considerably improved service lives and the cutting can be used to produce chips.
- the disks have holes, which means that the workpiece is particularly visible at very high speeds during machining.
- Such disks are milled from solid, for example, after which the cutting edges are attached accordingly.
- a shaped disk is known from DE 10 2016 123 832 A1.
- This shaped disk should be designed for the machining of materials such as aluminum, copper, plastic and the like, should have a high removal rate and should work as evenly as possible with a low load on the user.
- the shaped disk itself has holes in the disk which have cutting edges protruding from one side of a wide disk of the disk. The holes should ensure good chip evacuation on the one hand and good cooling on the other. In this way, high removal rates are to be made possible.
- the holes should also allow a view of the processing point.
- the edges of the holes running in the direction of rotation should be designed as cutting edges in order to ensure intensive material removal.
- the holes are to be arranged offset from one another on adjacent circular lines, with such a configuration also being used to reduce the tendency of the shaped disk to flutter or rattle.
- the flat working area should be followed by a working area on the edge, in which a plurality of side cutting edges extend along the outer circumference, by means of which the more flat machining can be done with the help the holes are to achieve intensive machining along an elongated, line-like area. This should, for example, be able to mill weld seams.
- the shaped disk according to this prior art should be formed in one piece in order to enable simple manufacture and high stability.
- the shaped disk can be produced in one piece from a forming tool, the shaped disk made from a heat-hardened and tempered steel, in particular from a 22MnB5 or 32MnB5.
- Post-treatment such as alloying or other coatings, is intended to achieve even higher hardness and tool life of the cutting edges.
- the steel grades used are known for their high hardness, which can be achieved by so-called press hardening.
- the surface should in particular have 40-65 HRC in order to be able to process light metals or non-ferrous metals as well as plastics or fiber-reinforced plastics, as well as wood and horn.
- such grinding and cutting disks are produced by cutting the holes and / or the outer contour in the forming tool or, in the case of a multi-stage production process, in a follow-on tool.
- the cut-outs in the tool are cut in the direction of the press.
- the angles of the hole cutouts on the fully formed 3D contour result (also uneven for each 3D contour) - and are therefore also not optimal for the cutting effect.
- US Pat. No. 4,685,181 A discloses a comparable processing disk which is intended to work in the manner of a rasp, this disk also being arranged on an angle grinder and having hole-like recesses in its surface, the rear edges of the holes being shaped outwards in order to Form cutting teeth.
- a saw blade is known from US 2002/0124707 A1, which has a grooved profile.
- the grooves serve to reinforce the saw body and prevent the saw blade from being deformed, especially for saw blades thinner than 1 mm.
- a saw blade is known from US 201 1/0000475 A1 which contains slot-like recesses, the recesses mentioned contributing to the heat reduction when attaching carbide particles.
- a disk cutter is known which has radial and axial recesses, the radial cutting edges being formed from a hard metal. The above-mentioned recesses serve to remove chips and reduce the weight of the disc cutter.
- DE 695 23 909 T2 describes a rotatable cutting tool which comprises a convexly designed cutting disk, the cutting disk having an arrangement of cutting teeth on the outside or convex side. Perforations are provided in the cutting disc for air movement so that chips are removed more effectively. The holes mentioned also serve to improve the visibility of the workpiece to be cut and help to swirl and move the air.
- a disk cutter is known from US Pat. No. 4,776,402, which has a plurality of rectangular recesses which serve for the visibility of the workpiece to be cut.
- the recesses are arranged diagonally and enable precise cutting control so that even shallow cuts can be made precisely.
- the grinding or cutting disks known from the prior art are either relatively inexpensive, but have a short service life and tend to develop dust when working on workpieces and do not have an optimal cutting edge geometry on all cutting edges, also because the peripheral edges show through can greatly change the machining of a workpiece.
- Expensive discs have a long service life and good chip formation, but are very expensive for this and also do not always have an optimal cutting edge geometry.
- the object of the invention is to provide a machining wheel which is wear-resistant and chip-forming and is suitable for both surface removal and piercing, separating machining, the workpiece being visible during machining and permitting high removal speeds, with defined cutting angles in all three directions, ie are also provided in the Z direction, both on the holes and on the outer edges.
- a processing disk is produced from a heat-hardenable, tempered steel, preferably a 20MnB8 or a 22MnB5 with a defined geometry and curvature, which enables both flat and piercing removal, in a hot forming process or the press hardening known per se.
- the processing disc can be used for surface and / or piercing machining, i.e. e.g. for grinding or roughing surfaces and / or for grooving and cutting workpieces or for cutting and cutting e.g. Profiles.
- a coated, in particular metal-coated, press-hardening steel material means that there is no need for a re-coating in the manufacturing process and the product is equipped with corrosion protection, which also applies to the storage of such a product until use, but also in use, especially in humid conditions Environment, is an advantage.
- a coating based on aluminum such as AISi alloys or a coating with an alloy based on zinc are possible as coating materials.
- Zinc alloys are advantageously applied to the strip in a molten state by means of a hot-dip galvanizing process.
- a galvanized material is used, the disk does not need to be descaled and surface-treated after press hardening, and no protective gas atmosphere is required as a protection against scaling during press hardening
- the machining wheel is machined by laser cutting, the inner holes and the outer edges being introduced, so that the machining wheel is made in one piece.
- the trimming takes place on all holes and outer cutters with optimally defined cutting angles in all three directions, including in the Z direction. The trimming is also possible in the course of the cutting edge.
- a changing cutting contour means that the required cutting angle (above all the cutting angle) for the desired removal rate, the desired chip type, the desired chip discharge, etc., via the curved processing disc (see claim 1: " ... outer radial circumference ... ”) is implemented. As mentioned, it depends heavily on the respective area of application which geometry is optimal.
- the shape of the disk and the cutting edges can be manufactured variably depending on the application and with the desired properties.
- the disk can be balanced and in particular integrated into the laser processing.
- laser cutting makes it possible to provide the disk next to the holes, if necessary in line-like recesses, in order to effectively control and suppress natural vibration of the disk.
- FIG. 1 a plan view of an embodiment of a machining wheel according to the invention
- FIG. 2 a further top view of a processing disc according to the invention with a section;
- Figure 3 shows a cross section of the disc of Figure 2
- FIG. 4 an enlarged detail from FIG. 3;
- Figure 5 the section Y-Y of Figure 2;

- Figure 7 the processing wheel of Figure 6 in a side view;
- FIG. 10 a cross section of the processing disk according to FIG. 6;
- Figure 1 1 the processing disc of Figure 6 in a further side view.
- a machining disk 1 according to the invention has a basically circular or circular disk-shaped base body with a receiving area 2 and, within the receiving area 2, a central bore 3 that is oriented axially to the Z axis.
- the receiving area 2 and the bore 3 serve to connect the Machining disc
- the processing disk 1 has an outer radial circumference 4 which runs perpendicular to the Z axis and a curved area 5.
- oval machining holes 6 are arranged offset to one another, where cutting edges 7 are formed in one piece along the circumference 4, the cutting edges 7 being formed by slots 8 in the circumference.
- the receiving area 2 and the circumference 4 lie on the XY plane, with a bulge extending from the receiving area 2, which is flat, out of this plane in the Z direction and then outwards Scope 4 drops.
- the curvature is rounded with a radius from the receiving surface
- the slope 9 to the apex 10 takes up about 1/3 of the total radial extent of the curvature, while the descending area 12 takes up about 2/3 to the outside.
- the area 12 slopes outwards in particular at an angle a (FIG. 10), the angle increasing in the area of the circumference due to the bend in the direction of the plane of the receiving area 2 by an angle ⁇ , so that there the inclination of the sum of the Corresponds to angles a and ⁇ (FIG. 10).
- the circumference 4 is preferably the largest in the area of the cutting edges 7, with a cutting back 13 being formed to ensure a suitable machining projection from the actual cutting edge 7, which is reduced towards the trailing cutting edge 7 so that the The circumference 4 in the form of the cutting back 13 is reduced to the subsequent slot 8.
- the side cutters preferably each have a cutting edge running in the direction of rotation, which extends at an angle g to the radial direction which is between + 10 ° and -10 °, preferably between + 5 ° and -5 ° (FIG. 6).
- the processing disc can be used for surface and / or piercing machining, i.e. e.g. for grinding or roughing surfaces and / or for grooving and cutting workpieces or for cutting and cutting e.g. Profiles.
- the preparation of fillet welds can be used particularly advantageously with the properties claimed and can be pierced with the side cutting edge and at the same time with the cutting edge on the top of the disc.
- the cutting edge on the broad side surface has a cutting edge angle g 'to the tool reference plane which is between + 10 ° and -10 °, preferably between + 5 ° and -5 ° (FIG. 11).
- the processing disc therefore has a first angle g and a second angle g 'which is in each case between + 10 ° and -10 °, preferably between + 5 ° and -5 °. Thanks to this positive rake angle, improved chip removal can be achieved with good cutting qualities and tool life at the same time.
- a bare or preferably galvanized steel strip is punched correspondingly to machining disc blanks 1 and the corresponding blanks are then shaped into the machining disc in a corresponding tool, for example a press hardness or hot-forming tool.
- the holes and the outer contour are then cut into the machining disk by laser, both the holes 6 and the slots 8, the cutting edges 7 and the cutting back 13 being cut by laser and provided with optimal cutting angles in all three orientations.
- Both the trimming of the holes and the external trimming take place in a cutting angle that is optimally selected for the respective area of use (FIGS. 4, 5).
- the processing disks 1 can optionally also be balanced as required.
- the concentricity can be considerably improved by balancing, preferably integrated in the laser trimming process.
- the measurement of the unbalance can preferably be carried out integrated into the laser machining process by means of a laser recording with corresponding force sensors or alternative optical measurement sensors.
- An advantage of the invention is that machining disks can be produced very precisely and with cutting edges optimally adapted to the area of application.
- the processing disk can have a metal-coated steel material as the base material.
- the coating can be selected from an alloy based on zinc or an alloy based on aluminum (such as AlSi).
- a galvanized, in particular hot-dip galvanized, press-hardenable steel sheet is used as the base material, it is also possible to produce a corrosion-protected processing disk which does not have to be descaled after forming and, moreover, does not corrode in practical operation, for example on a construction site.
- balancing it is advantageous that an existing imbalance of the machining disc can be implemented very easily by influencing the expansion of individual holes by means of laser balancing. It is also possible to easily create additional balancing holes or counterbores. These balancing holes or counterbores can be made in particular by means of laser cutting, but it is also conceivable to introduce them effectively using other machining processes, such as turning, drilling, milling, etc. This balancing method can be particularly advantageous for precision applications, i.e. higher-priced processing disks with a longer service life can be used.
