specific Embodiment approach 1

[0005] Specific embodiment one: the ultra-precision grinding diaphragm of the present embodiment is a laminar structure, and the bottom film layer 1 and the abrasive material layer 2 of the soft matrix are followed successively along the thickness direction of the diaphragm, and there are evenly fixed particles in the abrasive material layer 2. The abrasive material 3, the bottom film layer 1 and the abrasive material layer 2 are all made of resin material, and the resin is polyimide or polyamide-6 (PA-6). The abrasive 3 in the abrasive layer 2 is synthetic diamond (JR) abrasive, cubic boron nitride (CBN) abrasive, oxide (WA) abrasive or carbide (GC) abrasive. The particle size number of the abrasive material 3 is 18000-400, and the abrasive material concentration in the grinding layer is 50-200. The bottom film layer 1 of the ultra-precision grinding diaphragm of the present invention is made of a resin material with good temperature resistance and high tensile strength, and ...

specific Embodiment approach 2

[0006] Embodiment 2: The difference between this embodiment and Embodiment 1 is that there is a protective film layer 4 under the bottom film layer 1 , and the protective film layer 4 and the bottom film layer 1 are bonded together through the self-adhesive layer 5 . Its purpose is to facilitate the pasting of the membrane.

specific Embodiment approach 3

[0007] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the bottom film layer 1 and the abrasive material layer 2 are respectively processed into a two-body structure, and the bottom film layer 1 and the abrasive material layer 2 are covered with another self-adhesive layer 6 glued together. The above-mentioned bottom film layer 1 and abrasive material layer 2 can be processed by casting method or hanging film method respectively.

Abstract

A diaphragm for ultra-precision grinding relates to a new type of grinding tool. It is a sheet-like structure, along the thickness direction of the diaphragm, there are the bottom film layer (1) and the abrasive layer (2) of the soft substrate in sequence, and the abrasive material (3) is evenly fixed in the abrasive layer (2), and the bottom film layer (1) and the abrasive layer (2) are both made of resin material, and the abrasive (3) in the abrasive layer (2) is artificial diamond abrasive, cubic boron nitride abrasive, oxide abrasive or carbide abrasive; abrasive (3) The particle size number is 18000~400. The invention develops a tool for grinding abrasives in a fixed state, thereby changing the traditional grinding process, making the grinding process have the advantages of good grinding effect, high efficiency, processing complex components, automatic processing, and no environmental pollution .

Description

technical field [0001] The invention relates to a novel grinding tool. Background technique [0002] The existing traditional grinding and polishing process is to use grinding paste, grinding powder, or grinding powder mixed with kerosene and other liquids as abrasives, and use grinding rods and grinding discs made of cast iron materials as grinding tools for open grinding. Its disadvantages and deficiencies are: the abrasive is in rigid contact with the grinding workpiece. Due to the poor contour of the abrasive grains in the working process, the cutting, plowing, and sliding effects of different abrasive grains are different, and the grinding effect is poor; , it is not suitable to use high-priced superabrasives such as diamond and cubic boron nitride with good grinding effect and high efficiency. Hard material workpieces have low efficiency; the traditional open grinding method has a limited processing range, such as magnetic recording elements such as magnetic drums, ma...
