Example Embodiment
[0035] The first embodiment is an elastic emery cloth with a convex arc and an annular shape, which is produced by the following process:
[0036] 1 Select elastic modified plastic as the raw material of elastic layer 3; diamond or cubic boron nitride and brittle resin are used as abrasive particles 1, and the bottom of the abrasive particles is placed in the base cloth 2;
[0037] 2. Abrasive cloth: the base cloth with abrasive grains 1 is formed into a ring shape by rubber and plastic molding method and elastic layer 3
[0038] The emery cloth can also be uniformly bonded on the elastic layer 3 by applying glue to form an annular emery cloth.
[0039] Such as figure 2 , image 3 , Figure 4 , Figure 5 As shown, the shape of the outer convex arc annular elastic gauze 4 is the same as the shape of the outer edge of the support base 5, and its size is slightly smaller than the size of the outer edge of the support base 5. A raised ring is provided at both ends of the elastic laye...
Example Embodiment
[0041] Embodiment 2 is a roller-shaped grinding wheel, and its processing process is as follows:
[0042] Material selection: use silica gel as the elastic layer 2, cotton cloth as the base cloth 2, and silicon carbide particles as the abrasive particles 1;
[0043] 2. Abrasive cloth: evenly bond the abrasive grains 1 on the base cloth 2, and cut them into abrasive cloth strips with the same width as required;
[0044] 3. Forming: Put the cut emery cloth strip into the mold, inject silica gel to form the elastic layer 3, and make the sand cloth strip with abrasive 1 and the silica gel integrally form to form a roller-shaped elastic emery cloth 7;
[0045] 4. Suit: Put the roller-shaped elastic emery cloth 7 on the support base 8 to form a roller-shaped elastic grinding wheel.
[0046] Such as Figure 6 , 7 As shown in and 8, a raised ring 31 is provided at both ends of the elastic layer 3 of the roller-shaped emery cloth 7, and a grooved ring 81 is provided on the upper and lower ...
Example Embodiment
[0047] Example 3, such as Picture 9 with 10 Shown. It is a waist drum-shaped elastic emery cloth, and the elastic emery cloth 9 is sleeved on the supporting base 10. It can be used to grind and polish various curved surfaces.
