Accurate grinding and polishing block with high abrasive ratio and preparation method
The invention provides a high-attrition-ratio accurate-grinding polishing and grinding block and a preparation method, and relates to the technical field of polishing and grinding block preparation. The invention discloses a high-abrasive-ratio fine grinding and polishing block and a preparation method. The high-abrasive-ratio fine grinding and polishing block is prepared from, by weight, 20-60 parts of chrome corundum micro powder, 10-40 parts of aluminum oxide micro powder, 5-30 parts of feldspar powder, 10-40 parts of clay powder, 5-20 parts of quartz micro powder and 1-5 parts of others. Under the working conditions that the impact acceleration is 10 g and the linear speed is larger than 1.2 m/s, the rough grinding surface of 45 steel can be machined from Ra0.8 to Ra0.13 or below and from Ra0.3 to Ra0.1 or below within 30 min, the removal rate exceeds 0.2%, the rough grinding surface of materials such as high-speed steel, alloy steel and the like can be ground from Ra0.4 to Ra0.1 or below within 30 min, the material removal rate can exceed 0.15%, the characteristics of high grinding force, high abrasive ratio, high grinding quality and the like are achieved, and the grinding effect is good. The device is suitable for high-linear-speed and high-speed grinding and polishing application scenes, the machining efficiency can be greatly improved, the machining quality is improved, procedures are simplified, losses are reduced, the auxiliary time is shortened, and therefore mechanical production automation is guaranteed.
本发明提供一种高磨耗比精磨抛磨块及制备方法，涉及抛磨块制备技术领域。一种高磨耗比精磨抛磨块及制备方法，由下述重量份的组分组成：铬刚玉微粉20‑60份、氧化铝微粉10‑40份、长石粉5‑30份、黏土粉10‑40份、石英微粉5‑20份、其他1‑5份。通过在冲击加速度10g，线速度＞1.2m/s的工况下，可实现45钢粗磨表面在30mi n内从Ra0.8加工至Ra0.13以下，Ra0.3加工至Ra0.1以下，去除率超过0.2％，高速钢合金钢等材料粗磨表面在30mi n内从Ra0.4的研磨达到Ra0.1以下，材料去除率可超过0.15％，具有高磨削力、高磨耗比、高磨削质量等特点，适用于高线速度高速磨抛应用场景，可大幅提高加工效率、提高加工质量、简化工序、减少损耗和辅助时间，从而保障机械生产自动化。
