Applicationused to measure the straightness and flatness of the workpiece
The measuring temperature(20±5)℃
 technology scraper 
 raw material  HT250
 hardness 170-220HB
 Standard JB/T7977-99
The flatness of the flat plate and the long guide rail is checked by the coloring method and the indicator method, and the straightness of the edge of the workpiece is checked by the light gap method.
Advantage ruler is made by mechanical processing and manual fine grinding. Precision structure, uniform texture, good stability, high hardness, flat ruler can maintain high precision under heavy load and general temperature, with no rust, acid and alkali resistance, abrasion, non-magnetization, deformation and other advantages.
Bridge-type flat-scale working face shall not have defects such as sand holes, gas holes, cracks, slag inclusion, shrinkage, scratches, bruises, rust spots, etc., which seriously affect the appearance and service performance.
