我厂铸铁车间广大革命职工,在兄弟单位的配合下,进行了技术改造,自力更生制造了一台HMZ903型抛砂机,造型提高了工效,显著地减轻了劳动强度,深受造型工人的欢迎,随着造型工效的提高,原工艺制造的木模(表面喷涂油漆的木模),经不起抛砂机的砂粒高速喷压磨损,木模表面层的油漆严重剥落,以致损伤木模本体,木模使用2~3次漆膜开始脱落,
Our factory cast iron workshop revolutionary staff, with the cooperation of brothers units, carried out technological innovation, self-reliance created a HMZ903-type sand throwing machine, modeling to improve the work efficiency, significantly reducing labor intensity, welcomed by modeling workers, With the improvement of work efficiency, the original wooden mold (painted wood surface paint) can not withstand the sand blasting machine high-speed spray pressure wear, paint the surface of the wood mold serious peeling, resulting in injury wood body, Wood use 2 to 3 times the film began to fall off,
