TECHNICAL FIELD

[0001] The utility model relates to a polishing technical field, concretely is a kind of diamond thinning sheet. BACKGROUND

[0002] Diamond thinning sheet adopts resin and diamond micro powder, cutting force is strong, grinding effect is good, long in service life, is used to the polishing process of ceramic sheet, sapphire glass, sapphire cover plate, sapphire substrate sheet, ceramic sheet, reduce scratch processing before polishing, it is the product of ceramic, sapphire, silicon wafer, glass, crystal and so on precision grinding thinning.

[0003] The existing polishing sheet adopts fiber net to fix polishing particles in the processing process, the thickness is larger, and the fiber net can be easily separated, and the service life is shorter.

[0004] Therefore, it is necessary to provide a diamond thinning sheet to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of diamond thinning sheet to solve the above background technique proposed in the processing process of the existing polishing sheet that adopts fiber net to fix polishing particles, thickness is larger, and the fiber net can be easily separated, and the service life is shorter Problem.

[0006] To achieve the above object, the utility model is realized by the following technical scheme: a kind of diamond thinning sheet, including base body, the outer side of the base body is covered with adhesive layer, the outer side of the adhesive is bonded with diamond micro powder layer, the both sides of the base body are provided with fixed slot.

[0007] Preferably, the center of the base body is provided with assembly ring, the assembly ring is protruded to the both sides of base body, and the thickness of protrusion is same with the thickness of diamond micro powder layer.

[0008] Preferably, the center line of the fixed slot coincides with the diameter of base body, and the fixed slot is evenly distributed on the base body in radial direction.

[0009] Preferably, the thickness sum of the adhesive layer and diamond micro powder layer is 0.5 millimeter.

[0010] Preferably, the edge of the base body is evenly provided with tooth part.

[0011] Compared with prior art, the utility model provides a kind of diamond thinning sheet, with the following beneficial effects:

[0012] The diamond thinning sheet, by setting diamond micro powder layer outside base body, since diamond micro powder particle diameter is small, can be combined with adhesive layer uniformly, no longer use fiber net to fix, more light and thin, directly contact with adhesive layer, increase the degree of firmness, prolong use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figs. 1-3 As shown, a diamond thinning sheet includes a substrate 4, an adhesive layer 3 covering the outer side of the substrate 4, and a diamond micro powder layer 1 bonded to the outer side of the adhesive layer 3. Fixing grooves 5 are provided on both sides of the substrate 4. By setting the diamond micro powder layer on the outside of the substrate, due to the small diameter of the diamond micro powder particles, it can be evenly bonded to the adhesive layer. During production, the diamond micro powder is first evenly distributed on the outer side of the adhesive, and then cured at ultra-high temperature. This effectively forms a complete structure between the adhesive layer 3 and the diamond micro powder layer 1, preventing separation during use and eliminating the need for fiber mesh fixation. This results in a thinner and lighter sheet, while direct contact with the adhesive layer increases its strength and extends its service life.

[0019] An assembly ring 2 is provided at the center of the substrate 4. The assembly ring 2 protrudes to both sides of the substrate 4. The thickness of the protrusion is the same as the thickness of the diamond micro powder layer 1. The assembly ring 2 is used to connect with the grinding device. The protrusion of the assembly ring 2 can be on the same plane as the diamond micro powder layer 1.

[0020] The centerline of the fixing groove 5 coincides with the diameter of the substrate 4. The fixing groove 5 is evenly distributed radially on the substrate 4. The fixing groove 5 coincides with the tangent of the substrate 1, which can increase the friction and ensure the firmness of the diamond micro powder layer 1.

[0021] The combined thickness of the adhesive layer 3 and the diamond micro powder layer 1 is 0.5 mm, making the thinner sheet lighter and thinner overall while still achieving the desired polishing effect.

[0022] The edge of the base 4 is uniformly provided with a tooth part 6, which increases the friction force at the edge and has a certain cutting function.
