Optical polishing is a fabrication technique developed specifically to achieve minimal defects and smooth micro-roughness values. Polishing is a process that involves the use of free grains, usually suspended in a liquid (slurry) rather than bonded into a wheel as in grinding.<\/p>","imageObject":{"variants":[{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/d\/5\/csm_optical-polishing_2d64f56d92.jpg.webp","type":"image\/webp","name":"default","width":"570","breakpoint":"1200"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/d\/5\/csm_optical-polishing_2d64f56d92.jpg","name":"default","width":"570","breakpoint":"1200"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/magazine\/surface-metrology\/image\/optical-polishing.jpg.webp","type":"image\/webp","name":"large","width":"900","breakpoint":"992"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/magazine\/surface-metrology\/image\/optical-polishing.jpg","name":"large","width":"900","breakpoint":"992"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/d\/5\/csm_optical-polishing_1694898d64.jpg.webp","type":"image\/webp","name":"medium","width":"1380","breakpoint":"768"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/d\/5\/csm_optical-polishing_1694898d64.jpg","name":"medium","width":"1380","breakpoint":"768"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/d\/5\/csm_optical-polishing_e34750b991.jpg.webp","type":"image\/webp","name":"extrasmall","width":"640","breakpoint":"320"},{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/d\/5\/csm_optical-polishing_e34750b991.jpg","name":"extrasmall","width":"640","breakpoint":"320"}],"default":{"src":"https:\/\/magazine.polytec.com\/fileadmin\/_processed_\/d\/5\/csm_optical-polishing_2d64f56d92.jpg","alt":"","title":""}},"link":"https:\/\/magazine.polytec.com\/jp\/characterizing-surface-texture-roughness-imperfections-scratches","origUid":6147,"readingTime":"3 min","subline":"Quality control in optical polishing","tags":[{"title":"Mechanical & precision engineering","uid":8},{"title":"Production, process & quality","uid":12}],"technologies":[{"title":"Surface Metrology","uid":212}],"title":"Characterizing surface texture, roughness, imperfections and scratches","uid":6570,"visits":142},{"authors":[],"datetime":null,"description":"
