Abrasive Jet Polishing of Micro Groove Using Compound SiC Abrasives with Compound Additives
This Study Examined the Performance of Abrasive Jet Polishing (ajp) on Skd61 Mold Surfaces Using Wax-coated Sic Abrasives Fabricated by Gas Atomization. Comparison of Surface Quality Achieved Reveals Significant Surface Roughness Reduction by Wax-coated Abrasives. the Wax Coating Not only Covers Most of the Sharp Ends of the Abrasive, Thus Making Smooth the Abrasive Surface; it Being Elastic Also Provides a Cushioning Buffer. these Two Features Contribute to Ameliorate the Direct Impact of Heavy Peening, Thus Preventing Surface Hardening, Superficial Embedment or Deep Scratches. Moreover, Compound Additives Including Water Wax and Water Were Added to the Wax-coated #3000 Sic Abrasives at a Mix Proportion of 500: 1000: 1500 (water Wax: Wax-coated Sic: Water) for Polishing Mold Surfaces of Different Forms. Results Show that the Compound Additives Provide Addition Cushioning Effect and Facilitate the Sliding and Grinding of Abrasives, Resulting in Fine Polishing and Good Surface Quality. the Reflection Property of Micro-groove Was much Enhanced by Ajp Using Wax-coated #3000 Sic Abrasives with the Compound Additives.
