AN ANALYSIS OF AND APPROACH TO THE METHOD FOR TESTING THE PARALLELISM OF SAW GUIDE MOTION LOCUS AGAINST THE BLADE

The parallelism of saw guide motion locus against the blade is one of the main iterns in the testing of the geometric precision of the whole woodworking band saxving-machine. It reflects the making and mounting precisions of the sawguide device,having a direct effect on the working performance. the saw timber quality. and the safety (nature) of the woodworking band sawing-machine, so it is of great importance in the testing process of the band sawing-machine assembly and their going out of the plant.

锯卡运动轨迹对锯条平行度的检验方法分析与探讨

根据现行标准，分析了木工带锯机锯卡运动轨迹对锯条平行度的检验方法和使用的检验工具，指出正确理解检验方法的要点和目前检验用带锯条或无齿钢带代替检验钢带作为测量基准，不能满足测量基准的精度要求。提出用辅助平板贴靠无齿钢带作测量基准，解决检验钢带既薄又长，加工困难的问题。该方法可减少测量时的系统误差，提高测量基准精度，为带锯机整机几何精度检验结果的判定和评价质量提供了保证。
