本研究是利用冷凍機對拋光研究中所使用的拋光液進行溫度上的改變，進而改變其所呈現的形態，其主要目的是利用其形態的特點，使較環保的拋光液也能達到傳統拋光液的效果。藉由控制拋光液成分、拋光液重量百分比濃度、SiC號數、溫度、拋光頭與試片間隙、平台移動距離、平台移動速度…等一系列的實驗後，了解到拋光液的形態改變時，對於帶動其磨料(SiC)的方式也有所改變，進而可使油水混合拋光液也可加工出與傳統拋光液一樣的表面品質。
經一系列的實驗探討後可以得知，在較佳參數組合中，能讓油水混合拋光液於10分鐘有效改善不鏽鋼表面粗糙度由Ra 0.189μm改善至0.044μm，改善率達到76.75%，若是純油拋光液的話，其最佳改善率為73.05% (Ra 0.051μm)，除了表面粗糙度的比較外，從SEM圖上亦可看見油水混合拋光液同樣擁有完整移除氧化層的能力，由此可以證明油水混合拋光液在適當的條件下是可以完全代替純油拋光液來使用，甚至可以達到更好的加工效果。

A study of polishing for SUS304 with cooling abrasive liquid. This study is conducted using the cooler to change the temperature of polishing solution in this polishing research and change its form. The main purpose is using the feature of the form to make the environmentally-friendly polishing solution to achieve the effect of the traditional polishing solution. By controlling the polishing solution composition, the weight percent concentration of the polishing solution, the numbers of SiC, temperature, the polishing gap, the platform speed to design a series of experiments. We can comprehend how to change the way to drive its abrasive (SiC) when the form of the polishing solution changes. Then it can make the oil-water mixed polishing solution achieve the surface quality of the traditional polishing solution.
A series of experiments show that the combination of better parameters for the oil-water mixed polishing solution can be effective in improving the stainless S.R. of 10 minutes to reduce by Ra 0.189 μm to 0.044 μm, improvement rate was 76.75%. If it is the pure oil polishing solution, the improvement rate was 73.05% (Ra 0.051 μm). In addition to the comparisons of the surface roughness, we can also know the ability to remove oxide layer of the oil-water mixed polishing solution from the SEM images. This shows the oil-water mixed polishing solution under appropriate conditions can be completely instead of the pure oil polishing solution, and get better polishing quality.
