Scraped cast iron platform

At Hebei Beizhong manufacturer, for scraping the surface of the cast iron scraping plate, first polish it with an oilstone. After polishing, we use M4 sand to refine the surface of the cast iron plate. Three cast iron plates are ground against each other. When pushing and pulling becomes laborious, the cast iron scraping plate is removed. Scraping continues until the flatness of the cast iron scraping plate is satisfactory, ensuring a clear understanding of the process. For cast iron plates with minor scratches or impact damage during use, simply use an oilstone to grind down the raised parts. There is no need to scrape the cast iron plate; directly apply sand pressure instead.
When producing cast iron scraping plates, HT200-250 material is generally used. This material is prone to rust in humid environments. After using the T-slot platform, the working surface should be wiped clean promptly and coated with anti-rust oil. If it will not be used for an extended period, apply butter and then cover it with paper to ensure the cast iron plate does not rust during storage.
Inadequate implementation of anti-rust management systems, failure to adopt effective anti-rust measures, or significant temperature fluctuations in workshops and warehouses can all lead to surface rust on cast iron plates. For example, if stored cast iron plates exceed the anti-rust period, are placed in damp and unclean environments during temporary suspension of use, or are padded with moisture-absorbent and non-breathable materials, they will rust due to moisture and dirt.
During the use of the cast iron scraping plate, avoid striking its working surface with hard tools to prevent affecting the precision of the cast iron plate's working surface. To avoid permanent deformation of the cast iron plate, after workpiece inspection or marking is completed, the workpiece should be removed and not left on the cast iron plate for extended periods. It is best to make a dedicated cover from wood. When not in use, cover the working surface with the cover to reduce maintenance time and extend the service life of the cast iron plate.
