Definitions
- the invention relates to a roughing wheel.
- a relatively thick circumferential grinding wheel which consists of several reinforced with tissue, the entire surface glued together individual discs, wherein in the adhesive layer, an elastic insert may be provided. Such packages have a higher grinding performance than a one-piece compact disk.
- a compact disc is also known, each having abrasive-free zones in their radially outer regions, which are formed by annular spacers, which may optionally be removed again, so that a significant gap between the adjacent regions is formed , These abrasive-free zones lead to a particularly cool grinding during circumferential grinding and also produce additional chip space, which allows a substantial increase in the grinding performance with otherwise identical disk composition.
- a roughing grinding wheel is known whose diameter is at least a factor of 10 greater than its thickness.
- Such roughing wheels are used on hand-held, pneumatically or electrically operated angle grinders.
- strong vibrations occur in the grinding insert, which can cause considerable physical damage to the hand-arm system of the user.
- an annular separating layer is arranged between individual layers in an outer working region. Within this workspace, it has a compact design on. The separation layer has primarily the function of reducing the amplitude of vibration during grinding.
- the invention has for its object to provide a vibration-damped roughing grinding wheel for hand-guided use, which is particularly simple in construction and thus is particularly easy to produce.
- planar design of the roughing grinding wheel and the attachment of a hub in this makes it particularly advantageous to provide an internal thread in the hub, by means of which a screwing onto an external thread of an output shaft of a hand-held grinding machine is possible.
- a flat configuration no nut protruding beyond the roughing wheel is required for attachment to the drive shaft of the grinding machine, so that a flat or approximately planar use of the roughing grinding wheel according to the invention is also possible.
- This configuration of the hub can of course also be used in flat grinding wheels, which do not have the structure of the invention.
- FIG. 1 shows a hand grinder with a roughing wheel according to the invention in the grinding insert
- FIG. 5 is a side view of a roughing wheel according to the invention mounted on the output shaft of a hand grinder.
- roughing wheels 1 are used on hand grinders 2, namely so-called angle grinders.
- the grinding wheel 1 has for this purpose a central opening 3, in which a hub 4 is inserted.
- This hub 4 has a
- the grinding wheel 1 consists in its basic structure of several, namely two to ten, thin part discs 8 with an outer diameter D. Each part disc 8 has on its two outer sides depending on a reinforcement 9,
- the reinforcements 9, 10 consist of one with the binder of the abrasive grain
- a plurality of planarized dividing disks 8 are stacked on top of one another, wherein in each case an adhesive layer 12, generally thermosets, is applied in an annular region around the central opening 3.
- This adhesive layer 12 with a diameter d is in each case so thin that when the package is pressed from a plurality of dividing disks 8 into a roughing grinding disk 1, the adhesive is absorbed in the surface roughness of the adjoining dividing disks 8.
- the dividing disks 8 in the region of the adhesive layer 12 with the diameter d are fixedly connected to each other, and that they are not connected to each other outside of the respective adhesive layer 12, but are close together.
- the hub 4 passes through the central opening 3 of the grinding wheel 1 on one side, on the side facing away from the grinding machine 2, only slightly with a flanged edge 14, so that the roughing grinding wheel 1, although not cranked, but completely flat is formed, as a roughing grinding wheel 1, ie in the manner described above and shown in Fig. 1, can be used obliquely. But it is also a surface grinding possible in which the roughing grinding wheel 1 with its the edge 14 of the hub associated end face 15 is used flat or approximately flat on a workpiece 16. If the roughing grinding wheel 1 is inserted obliquely as shown in FIG.
