我厂机修车间自制的一台单臂、工件落地式导轨磨床使用至今已有六年。在此期间我们摸索到一些安装、调整以及使用方面的经验。现介绍于下:实践说明有三个关键因素会影响导轨磨床磨削工件的精度,即:机床床身的变形、工件的装夹变形以及工件磨削时发热引起的变形。一、机床的合理安装和调整由于导轨磨床的床身较长,刚度也较差,因此,其导轨的不直度受安装精度和温度变化的影响很大,而且又会直接反映到工件的精度上去,所以安装时需注意下列三点: I plant a machine repair shop self-arm, workpiece-based rail grinder has been used for six years. During this period we have found some experience in installation, adjustment and use. Now introduced in the next: Practice shows that there are three key factors that will affect the accuracy of rail grinding machine grinding, that is: the deformation of the machine bed, workpiece clamping deformation and workpiece deformation caused by fever. First, the rational installation and adjustment of the machine Because the rail grinder bed longer, the stiffness is also poor, so the rail is not straightness by the installation accuracy and temperature changes are greatly affected, and will be directly reflected in the accuracy of the workpiece Up, so the installation should pay attention to the following three points:
