Scraping and grinding knife

Name: Scraping and Grinding Knife

Alias: Flat scraper, fitter scraper, fitter scraper, scraper

Scraping and grinding knife is a scraping tool used for scraping and repairing goods, machine tools, equipment, flat surfaces, etc. It is a tool used by fitters to scrape metal, usually an alloy head scraper with high hardness.

Using a scraping knife to manually scrape and grind the flatness, parallelism, roughness, etc. of a workpiece is called scraping or scraping.

The guide rails, drag plates, and sliding bearings of a flat scraper are usually precision machined using scraping and grinding methods,

Scratching is a flat light http://www.btjxjt.com One of the methods of machining Its purpose is to reduce surface roughness values, improve contact accuracy and geometric accuracy, thereby enhancing the fit stiffness, lubrication performance, mechanical efficiency and service life of machine tools. It is also a necessary processing technology for high-end machine tools and cast iron flat plates that is difficult to achieve with only surface grinders and guide rail grinders,

The so-called "scraping and grinding" refers to the combination of scraping and grinding processes That is, flat scraping - grinding display, then flat scraping - grinding display, and so on, alternating cycle, constantly operating Gradually reduce the surface roughness value and positional error of the cast iron flat plate; Contact accuracy and geometric accuracy gradually improve during operation until they meet the specified requirements.
