在刮削平面中有时由于刮刀刃与工件表面不平行,造成工件表面有乱刀痕,影响光洁度,产生这种情况的主要原因是,刮刀柄部与身体接触过紧而引起的,为了准确地把工件表面高点刮掉,我们改进了一种活柄平面刮刀,使用效果较好,其构造见图。这种刮刀在刮削时,刃部可以与工件自由结合,保证工件与刀刃平行,只需要一般的刮削动作就可 In the scraping plane sometimes scraping edge and the workpiece surface is not parallel, causing the workpiece surface chaos marks, affecting the finish, the main reason for this situation is that the scraper handle and body contact caused by too tight, in order to accurately Scratch off the high surface of the workpiece, we have improved a kind of live handle flat scraper, the use of better, its structure shown in the figure. This scraper scraping, the blade can be freely combined with the workpiece to ensure that the workpiece parallel to the blade, only the general scraping action can be
