Polishing is the removal of material to produce a scratch-free, specular surface using fine (<3µm) abrasive particles.Polishing is typically done at very low speeds using either polishing cloths, abrasive films, or specially designed lappingplates. Polishing with a cloth or lapping plate requires the use of free abrasive, and is a very low damage process whenperformed properly. Plate material and cloth material are critical when polishing a particular sample as the properties ofthese substrates are important in the final polish quality of the specimen.Polishing with a lapping plate is a common process used in the case of metals and hard ceramic type materials.Polishing using copper composite plates or tin / lead lapping plates can produce high quality surface finishes with highremoval rates. In many cases the use of a polishing cloth is required, and thus the selection of a proper polishing clothis important. Polishing cloth properties needed depend on the application. If flatness is of primary concern, short napcloths (such as Nylon) are used to maintain flatness. When the final surface finish is of primary concern, longer nappedcloths (such as Rayon and Silk) are used. Many cloth materials today combine the best of both worlds, allowingflatness and surface finish combined to provide maximum performance. Polyurethane pads are commonly used forfinal polishing processes and produce excellent flatness and surface finish.ยังขัดกับภาพยนตร์ที่มีฤทธิ์กัดกร่อนก่อให้เกิดผลลัพธ์ยอดเยี่ยม ความเรียบของภาพยนตร์ร่วมกับการกำจัดสูงราคาพิเศษทำให้ผ้าและแผ่นขัดวิธีทางเลือกน่าสนใจ
