Definitions
- the present invention relates to a cutting disc with a diameter of more than 500 mm, which can be clamped between clamping flanges, with a mixture of abrasive grit, binder and, if appropriate, fillers, which extends from the outer edge of the cutting disc to the central bore, the cutting disc being provided on the side with steel sheets or steel grids is.
- the grinding wheel shown in US Pat. No. 1,600,064 has lateral supports of the same area with the clamping flanges. These conditions are therefore not able to distribute the clamping forces over the clamping flanges over a large area. A radial one Increasing the number of supports shown in US Pat. No. 1,600,064 would reduce the possible depth of cut.
- the steel sheets or steel grids are inserted flush in recesses in the side surfaces of the cutting disc and have a minimum thickness of 0.5 mm and a radial extension that exceeds the radial extension of the clamping flanges.
- the steel sheets or steel grids which are inserted flush on the sides into the axial end faces of the cutting disc, result in a large-scale distribution of the clamping forces emanating from the clamping flanges. Since the steel sheets or steel grids extend radially further outwards than the clamping flanges, the cutting disc is stabilized over a large area. Due to the flush embedding of the steel sheets or steel grids, which ensures an unchanged cutting depth up to the clamping flanges, a sufficient minimum thickness of at least 0.5 mm can be selected, which ensures an optimal distribution of forces.
- the steel sheets or steel grids are glued to the cutting disc.
- the steel sheets or steel grids can thus also optimally absorb the bending stresses occurring in the edge zones of the cutting disc, so that wobbling is effectively prevented.
- the steel sheets or steel grids have a substantially round shape.
- the cutting disc can have at least one fabric insert in a manner known per se.
- the method according to the invention provides that first a steel sheet or steel grid with a minimum thickness of 0.5 mm and with a radial extension of the Extending clamping flanges placed on a press plate, then the mixture of abrasive grain, binding agent and possibly fillers is applied and finally compacted so that the steel sheet or steel grid is inserted flush in the side surface.
- This manufacturing process is particularly cheap in terms of production technology and at the same time ensures a firm hold of the steel sheets or steel grids.
- This hold can be further improved by providing the steel sheets or steel mesh with an adhesive, in particular epoxy adhesive, on the side facing the cutting disc before the pressing.
- FIG. 1 is an exploded view of a cutting disc according to the invention
- Fig. 2 is a section through the cutting disc along the line A-A in Fig. 3 and Fig. 3 is a side view of the cutting disc.
- the cutting wheel 1 shown in the figures is a synthetic resin-bonded grinding wheel.
- Various phenolic resins are used as synthetic resin, through their specific selection in conjunction with the choice of abrasive and fillers, the grinding behavior and the degree of hardness of the cutting disc are adapted to the respective requirements.
- abrasives such as silicon carbide and corundum are preferably used as abrasives.
- Solid lubricants such as pyrite and graphite, as well as customary powdered materials for plastic reinforcement such as calcium carbonate or glass powder are used as fillers.
- the diameter d of the cutting disc 1 is typically between 800 mm and 1800 mm.
- the ratio of diameter d to width b is over 80, preferably even over 100. This ratio is to be increased still further on the basis of the present invention. It should be noted that the width b of the cutting disc 1 is drawn many times too large in relation to the diameter d in the figures for reasons of clarity.
- the cutting disc 1 has depressions 3 in the lateral end faces, which extend over a diameter range of the diameter d from 45% to 80%.
- the steel sheets or steel grids 2 are inserted essentially flush into the recesses 3.
- the steel sheets or steel grids 2 have a minimum thickness of 0.5 mm and can be up to 3.0 mm thick, the usual values being between 1.0 mm and 2.0 mm.
- the steel sheets form a closed surface, whereas steel grids are understood to mean structures which have recesses, in particular rectangular recesses.
- the steel sheets or steel grids 2 are glued to the remaining cutting disc 1.
- the steel sheets 2 are round, as can be seen from FIG. 3. Even if the round shape is favorable for smooth concentric properties, any other shapes, in particular polygon shapes, are also conceivable.
- Fig. 1 the two cooperating clamping flanges 5a and 5b are shown, with which the power transmission to the cutting disc 1 takes place.
- the steel sheets or steel grids 2 mean that the introduction of force is not only limited to the area of the clamping flanges 5a and 5b, but extends essentially over the entire area covered by the steel sheets or steel grids 2. The stabilization of the cutting disc 1 thus extends radially outward.
- the cutting disc 1 has a fabric insert 6. It is a resin-impregnated glass fiber fabric.
- the fabric insert 6 stabilizes the cutting disc 1 and prevents the occurrence of stray disc fragments if the disc fails.
- the present invention allows only one or at least a few fabric inserts 6 to be used. A variant without a fabric insert is also conceivable. This is advantageous insofar as the volume of the fabric can be replaced by abrasive grain when the fabric layers are reduced, which improves the grinding properties.
- the cutting disks according to the invention are produced in such a way that
- a steel sheet or steel grid 2 is first placed on a round press plate and then
