经济车刀是硬质合金车刀的一种新形式,它的结构简单,使用方便。经济车刀的刀头銲接在刀柱体上,而刀柱体带有锥度,与刀杆上的锥度配合成一个整体。这种车刀有如下的特点: 1)可以利用报损的硬质合金小刀头,将它銲接在经济车刀的刀柱体上,这样可以节约大批硬质合金刀头。同时,由于改进了原来固定形式的硬质合金车刀,就克服了刀杆祗能銲一两次刀头就不能再用的毛病。经济车刀的刀杆制成后,可以利用很长的时间而不需更换,因而可以节约刀杆材料。
Economic turning tool is a new form of carbide turning tool, its structure is simple and easy to use. The knife of the economic turning tool is welded on the tool post body, and the tool post body is provided with a taper, which is matched with the taper on the tool post. This type of turning tool has the following features: 1) The cemented carbide tip can be used to weld it to the knife body of economic turning tool, which can save a large number of carbide cutting tips. At the same time, due to the improvement of the original fixed form of carbide lathe, to overcome the knife can only be welded once or twice the head can not reuse the problems. After the economic knife arbor is made, it can take a long time without the need to change, which can save the arbor material.
