Problems solved by technology

Due to the elasticity of the hemp wheel / cloth wheel itself, processing in this way will affect the straightness and flatness of the frame, which cannot meet the needs of high-quality, high-precision grinding
[0004] The way that the existing grinding head maintains the hardness of the head by air pressure is unreliable. When the air pressure is unstable, the arc curvature of the head will be changed, resulting in poor contact with the workpiece surface, affecting the processing accuracy and error range, and the grinding head Not too wear-resistant, which affects the processing progress

Abstract

The invention relates to the technical field of polishing machining, and in particular relates to a polishing grinding tool and a preparation method thereof. The polishing grinding tool comprises a knife handle and a grinding head, wherein a pattern part is arranged at one end of the knife handle, the pattern part is sleeved with the grinding head, and the grinding head and the knife handle are arranged along a same central axis; the grinding head comprises an elastic deformation rubber layer and a resin grinding material layer coated on the outer surface of the elastic deformation rubber layer, and the resin grinding material layer is made of a material for the grinding material layer; and the material for the grinding material layer comprises the following raw materials in parts by weight: 25-35 parts of light-cured resin, 8-12 parts of filler, 55-65 parts of a grinding material and 0.4-0.8 part of assistant. The polishing grinding tool is simple and reasonable in structure, good inpolishing effect, high in abrasion resistance and long in service life. The grinding head made of the material for the grinding material layer is reliable in performance, stable in rigidity, resistantto abrasion and not prone to damage. The economic and practical performance is improved, and the defects in the prior art are overcome.

Description

Technical field [0001] The present invention relates to the field of polishing technology, and particularly relates to a preparation method of polishing abrasive. Background technique [0002] In real life, many products because the surface precision or for aesthetic considerations require polishing, which is primarily through a high-speed rotating grinding polishing surface so as to move on the need to polish the surface. [0003] With the development of science and technology in people's aesthetic requirements and is constantly upgrading, sweeping light treatment will become more and more important, improve the finish sweep of light refers to the object surface by polishing the way, more smooth and beautiful, such as stainless steel phone frame, straight edge pieces of the structure, currently mostly used flax wheel, cloth wheel with a suitable polishing wax polishing. Since Ma wheel / wheel cloth itself has elasticity, this way can affect processing and flatness straight borde...
