cast iron scraping plate

详情描述：

Scraped Surface Plate
Scraping involves scrape and lapping. After many times’ scraping ad lapping, the  surface roughness and geometrical errors of the Scraped Surface Plate are reducing gradually and the contact accuracy and geometric accuracy of the Scraped Surface Plate are improved gradually until all the values reach to the requirements.
        
刮研平台用途：适用于各种检验工作，精密测量用的基准平面；用于机床机械检验测量基准；检查零件的尺寸精度或形为偏差，并作紧密划线，在机械制造中也是不呆缺少的基本工具。
 
Usage:
Scraped Surface Plate is always used as the datum for measurement of the machinery parts’ geometric tolerance,such as flatness, parallelism, straightness and more. It is also can be used for precision inspection, marking out (layout), and tooling setup. It is an indispensable basic equipment in most mechanical manufacturing industries.
