在检定量块的过程中,经常要对量块进行修理。量块修复的主要方法就是精密研磨,而平板压砂是量块修理工作的重要环节,压砂前平板作一次充分的研磨,就容易使磨料(金刚砂)压上、压牢,从而提高量块修理的效率。一、场地环境的要求为避免平板表面划痕和碰伤,保持良好的平面度,研磨时对环境要求很严,实验室内应做到不起尘、进灰、藏灰,四周墙壁和地板必须涂上油漆;有恒温和 In testing the process of measuring the block, often to repair the block. The main method of measuring block repair is precision grinding, and flat sand is an important part of the measuring block repair work, sand before the flat for a full grinding, it is easy to make the abrasive (Emery) pressure on the pressure, thereby increasing the amount of block The efficiency of repair. First, the site environment requirements In order to avoid scratches and scratches the surface of the flat to maintain good flatness, grinding on the environment is very strict, the laboratory should not be able to dust, into the ash, possession of ash, around the walls and the floor must Painted; there is constant temperature
