Definitions

  • the base plate has second suction holes, which are arranged for engagement under the first suction holes of the steel strip. This ensures optimal extraction of the dust generated during operation. This leads to a low burden on the user.
  • FIG. 2 shows the distribution of the first suction holes 4 in the carrier plate 2. They lie on a circle 10 around the center 9 of the support plate 2.
  • the coating with hard metal grain 11 is on the entire surface of the steel strip 12, wherein the first suction holes 4 are of course not coated.
  • the channel-like first suction holes 4 are visible in the steel strip 12.
  • the walls 6 of the deep-drawn first suction holes 4 are shown cut.
  • the coating with hard metal grain 11 extends over the entire surface of the steel strip 12.
  • the walls 6 of the first suction holes 4 are formed so that they can engage in second suction holes not shown in a base plate of the delta sander, not shown. This serves as adjustment aid in order to be able to arrange the first suction holes directly above the second suction holes and thereby achieve the best possible suction of the grinding dust.
  • FIG. 5 shows an abrasive body 1 for an orbital sander.
  • the said differs from the grinding wheel 1 for the delta sander substantially only by its external shape. Again, deep drawn first suction holes 4 are formed. Its surface is coated with a hard metal grain 11.
  • the grinding wheel 1 for the orbital sander is also glued to the base plate (not shown) made of PU.
