Hebei Beizhong manufacturer for scraping cast iron platform surface scraping first use oilstone to polish, after polishing, we first use M4 sand to repair the cast iron platform plate surface, three cast iron platforms grind each other, when pushing and pulling laborious, remove the scraping cast iron platform, until the flatness of the cast iron scraping plate is better, stop scraping the cast iron platform, so that the heart has a number. For the use of scratches, bruises lighter cast iron plate, only with oilstone to polish the raised part down on the line, do not scrape the cast iron platform, direct pressure sand can be.
Production scraping cast iron platform generally uses HT200-250 material, this material in a humid environment is very easy to rust, after using the T-slot platform, the work surface should be wiped clean in time, and coated with anti-rust oil, if not used for a long time, should be coated with butter and then covered with paper to ensure that the cast iron platform will not rust in storage.
Anti-rust management system implementation is not in place, no effective anti-rust measures are taken, or the workshop, warehouse temperature changes are large, will lead to the cast iron platform surface rust. For example, stored cast iron platform beyond the anti-rust period, the suspended use of cast iron platform placed in a humid, unclean environment, or with moisture-absorbing and impermeable materials as padding, will be due to moisture and dirt and other causes of cast iron platform rust.
The use of scraping cast iron platform should avoid the use of hard tools to knock its work surface, in order to avoid affecting the work surface accuracy of the cast iron platform. In order to prevent the cast iron platform from permanent deformation, after the workpiece inspection is completed or the scribing is completed, the workpiece should be removed and not placed on the cast iron platform for a long time, it is best to use wood to make a special cover, when not in use, cover the work surface with a cover to ensure that the cast iron platform maintenance time is shortened and the service life is extended.
