Definitions
- Delta, eccentric and orbital sanders for example, are known for grinding surfaces. To process the surface, these have a motor-driven sanding plate made of PU foam, to which an abrasive body is applied.
- the abrasive wheel is an abrasive paper or abrasive cloth on which abrasive grains are applied. On its side facing away from the abrasive grains, the abrasive paper or abrasive cloth has a piece of velor with which it is connected to the abrasive plate by means of a Velcro strip attached to it.
- a short service life can be achieved with the known grinding wheel, since the grinding grains are quickly worn out when grinding hard surfaces or quickly become clogged when grinding coated surfaces. Such grinding tools must then be replaced.
- the removal rate Even when the grinding wheel is fresh, low, so that the same area has to be worked on for a very long time until the desired grinding result is achieved.
- An inventive abrasive wheels with the features of claim 1, an inventive abrasive having the features of claim 6 and a Inventions' according to electric grinding tool having the features of claim 8 have, by contrast, they have the advantage of a high lifetime and removal.
- a steel strip is used as the carrier plate instead of a sandpaper or "abrasive web on which an abrasive grain is deposited hard metal grain.
- the use of a steel tape as a support plate that this is compressed and thereby deforms like a Ziehhar- onika is avoided,
- the use of a steel band makes it possible to use a hard metal abrasive grain which is applied to the steel band by means of a special soldering process.
- this soldering process is not decisive for the invention, its further explanation is dispensed with in the context of this application.
- the use of a carbide grit as an abrasive grit means that an extremely long service life is achieved since the wear is hardly noticeable, even when sanding surfaces that are coated with varnish
- the grinding wheel should not be disposed of after it has clogged up with paint, but the paint can simply be brushed or tapped off. The grinding wheel is then ready for use again and is practically in its original condition. Moreover the use of carbide grit also increases the aggressiveness when grinding, so that a high stock removal rate is achieved.
- the abrasive body With a thickness of 0.3 mm, the abrasive body has approximately the same weight as the conventional abrasive paper made of sandpaper with abrasive grains and a velor layer. The thinner the steel strip, the greater its tensile strength must be in order to prevent compression.
- FIG. 2 is a plan view of the abrasive from direction II in Figure 1,
- FIG. 3 shows a section through the abrasive of FIG. 2 along the line A-A
- FIG. 4 shows a perspective view of the abrasive from FIG. 2,
- Figure 5 shows an abrasive body 1 for an orbital sander.
- the grinding body 1 for the delta sander essentially only by its outer shape.
- Deep-drawn first suction holes 4 are also formed here. Its surface is coated with a hard metal grain 11.
- the grinding body 1 for the orbital sander is also glued to the base plate (not shown) made of PU.
