The equipment allows for precise adjustments such as continuous speed control and shaft length, enabling craftsmen to leverage their skills. Furthermore, the types of buffs and polishing compounds can be freely customized to match the object being polished.<br \/>\n<img class=\"alignnone size-full wp-image-3729\" src=\"https:\/\/www.mako-metal.com\/makomtl\/wp-content\/uploads\/2023\/04\/\u30b9\u30c6\u30f3\u30ec\u30b9\u30d0\u30d5\u7814\u78e82.jpg\" alt=\"\" width=\"800\" height=\"533\" \/><br \/>\nTo polish an object, it is brought into contact with the buff and polished while adjusting the applied pressure and the rotational speed of the buff. Initially, the process starts at around #400 grit and eventually progresses to achieving a mirror finish using this equipment.<\/p>\n<h2><span id=\"Polishing_Compounds_Used_in_Manual_Polishing\">Polishing Compounds Used in Manual Polishing<\/span><\/h2>\n<p>The choice of polishing compounds in manual polishing depends on the grade of polishing, the type of material being polished, and the type of metal. Particularly for non-ferrous metals, specific polishing compounds are required to ensure the desired quality grade. Regarding mirror polishing, the combination of polishing compound and buff is particularly crucial.<br \/>\n<img class=\"alignnone size-full wp-image-3722\" src=\"https:\/\/www.mako-metal.com\/makomtl\/wp-content\/uploads\/2023\/04\/image3.jpg\" alt=\"\" width=\"800\" height=\"533\" \/><\/p>\n<h2><span id=\"Buffs_Used_in_Manual_Polishing\">Buffs Used in Manual Polishing<\/span><\/h2>\n<p>Various types of buffs are used in manual polishing. Hard buffs are ideal for removing rough metal surfaces or scratches. Coarse buffs are used for repairing welded areas with grinding marks. On the other hand, achieving a fine, polished, and shining surface, such as a mirror finish, requires the use of extremely soft buffs.<br \/>\n<img class=\"alignnone size-full wp-image-3723\" src=\"https:\/\/www.mako-metal.com\/makomtl\/wp-content\/uploads\/2023\/04\/image4.jpg\" alt=\"\" width=\"800\" height=\"533\" \/><\/p>\n<h2><span id=\"Buff_Used_for_Removing_Black_Scale\">Buff Used for Removing Black Scale<\/span><\/h2>\n<p>Stainless steel hot-rolled materials (No.1) and black scale materials made of iron are covered with a hard oxide film on their surfaces. Therefore, the first step involves removing this hard oxide film and leveling the surface finely. For this task, buffs arranged in a ring shape with sandpaper attached are used.<br \/>\n<img class=\"alignnone size-full wp-image-3724\" src=\"https:\/\/www.mako-metal.com\/makomtl\/wp-content\/uploads\/2023\/04\/image5.jpg\" alt=\"\" width=\"800\" height=\"533\" \/><\/p>\n<h2><span id=\"Polishing_Machinery_Used_in_Manual_Polishing\">Polishing Machinery Used in Manual Polishing<\/span><\/h2>\n<p>Generally, small objects are processed using stationary buff polishing equipment. However, large tanks or structures require individuals to enter and perform polishing or polish the surfaces from the surrounding areas. Therefore, portable polishing machinery that can be held by hand is used for polishing operations.<br \/>\n<img class=\"alignnone size-full wp-image-3725\" src=\"https:\/\/www.mako-metal.com\/makomtl\/wp-content\/uploads\/2023\/04\/image6.jpg\" alt=\"\" width=\"800\" height=\"533\" \/><br \/>\n<img class=\"alignnone size-full wp-image-3726\" src=\"https:\/\/www.mako-metal.com\/makomtl\/wp-content\/uploads\/2023\/04\/image7.jpg\" alt=\"\" width=\"800\" height=\"533\" \/><\/p>\n<h2><span id=\"Summary\">Summary<\/span><\/h2>\n<p>Recently, there have been DIY polishing tutorials and videos on the internet. However, it is safer to undergo grinding and polishing training, such as using grinding grinders. It is essential to always wear protective goggles, masks, and take various safety precautions, such as preventing the scattering of particles and inhaling dust.<br \/>\nWhen polishing hollow objects like pipes, it produces loud noise. Prolonged exposure to loud noise can be harmful to the ears. Therefore, we recommend taking thorough safety measures when engaging in polishing activities.<\/p>\n<p><img class=\"alignnone size-full wp-image-3727\" src=\"https:\/\/www.mako-metal.com\/makomtl\/wp-content\/uploads\/2023\/04\/image8.jpg\" alt=\"\" width=\"800\" height=\"533\" \/><br \/>\n<Anti-Fingerprint Coating><br \/>\n*This product is sold by our subsidiary.<br \/>\nIt is available for purchase online.<br \/>\nMaCoat GC<\/p>\n<blockquote class=\"wp-embedded-content\" data-secret=\"yAULhRIUur\"><p><a href=\"https:\/\/www.top-macoat.co.jp\/coating\/\">\u91d1\u5c5e\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0\u6db2\u8ca9\u58f2<\/a><\/p><\/blockquote>\n<p><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; clip: rect(1px, 1px, 1px, 1px);\" title=\"&#8220;\u91d1\u5c5e\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0\u6db2\u8ca9\u58f2&#8221; &#8212; \u30c8\u30c3\u30d7\u30de\u30b3\u30fc\u30c8\" src=\"https:\/\/www.top-macoat.co.jp\/coating\/embed\/#?secret=ZNEUeaTNaP#?secret=yAULhRIUur\" data-secret=\"yAULhRIUur\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><br \/>\n<a href=\"https:\/\/mako-gallery.jp\/collections\/tools\">\u6750\u6599\u30fb\u9053\u5177<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Stainless steel polishing can be broadly divided into two methods: machine polishing using equipment for polishing plates, structural steel, pipes, and other materials, and manual polishing for shaping objects and small items.
