X2012A龙门铣床是一种用途广泛的大型机床,它在我厂生产中发挥着重要作用。但因缺少工作台微动调整机构,在使用中深感不便。工件与铣刀在横向和垂直方向可用手动微调,而工作台的纵向微调只可点动,最低进给速度为20mm/min,难以保证精确定位。在实际操作中,常常因点动过位而撞坏刀具。有时因点动不到位而形成接刀处的台阶,影响加工质量。82年,我们利用大修机会增设了工作台手动微调机构。经改装后的龙门铣床使用效果很好,方便了生产,现
X2012A gantry milling machine is a kind of large-scale machine tool, which plays an important role in the production of our factory. However, due to lack of workbench fretting adjustment mechanism, in the use of deep inconvenience. Workpiece and cutter can be manually and finely adjusted in the horizontal and vertical directions. However, the longitudinal fine adjustment of the worktable can only be performed with a minimum feedrate of 20mm / min, which makes it difficult to ensure accurate positioning. In practice, it is common for the tool to be knocked over by moving it bit by bit. Sometimes due to the point is not in place to form a knife at the step, affecting the quality of processing. In 82 years, we used overhaul opportunities to add a manual fine-tuning workbench. After the modified gantry milling machine with good results, to facilitate the production, now
