How scraping crossed platform of

Precision crossed platform is to go through the manual scraping, the preferred is crossed plate rough scratch: cast iron plate Face rough, deep or surface machining marks badly rusted, working surface is uneven or distorted, scraping margin When 0.005mm or more, should be thick scratch. Rough scraping crossed platform is the use of artificial scraper with a long, long stroke (10mm ~ 15mm between), marks a wider (10mm), blade marks forward, into a piece of non-repetition. Scrape marks after machining can be applied diluted red iron oxide, with flat foot inquiry point, and show the high point shaving. When the crossed platform, cast iron platform surface research point per 25 square meters × 25 square from 4 to 6:00 and left a fine scratch allowance, it can begin fine scratch. When crossed platform is to fine-scraping high crude scrape after scrape, which is characterized by short-scrape method (marks width 6mm, length 5mm ~ 10mm), research point spread fast. When fine scrape to scrape certain direction, scraped again, scraping a second time to a 45-degree or 60-degree direction cross scraped texture. When the average research point per 25 square meters × 25 square meters is from 10 to 14 points, crossed platform fine scratch even completed.
