众所周知,铸件壁厚是指由铸型与铸型、铸型与型芯、型芯与型芯之间构成的铸壁厚度。壁厚检测是铸件尺寸检查中的一项内容,其目的在于保证铸件壁厚符合标准,以达到规定的机械性能要求;保证各机械加工部位有适当的加工余量,以满足铸件与其它零件的接触面和配合部位的加工精度及表面粗糙度的要求;通过对检测结果的分析,发现问题并寻求改进方法,以便进一步提高铸件尺寸精度。如果铸件壁厚超出了允许的范围,就可能产生一系列不良后果: As we all know, casting thickness refers to the casting mold and the mold, mold and core, core and core formed between the thickness of the casting wall. Wall thickness inspection is part of casting size inspection, the purpose is to ensure that castings meet the standard wall thickness, in order to achieve the required mechanical properties; ensure that the machining parts have appropriate allowance to meet the casting and other parts of the Contact surface and mating parts of the machining accuracy and surface roughness requirements; through the analysis of test results, identify problems and seek improved methods to further improve the dimensional accuracy of the casting. If castings wall thickness is beyond the allowable range, it may have a series of adverse consequences:
