数控车刀（NC lathe tool） Types and uses of turning tools Turning tool is one of the most widely used single edge cutting tools. It is also the basis of learning and analyzing all kinds of cutting tools. Turning tools are used on various lathes to process excircle, inner hole, end face, thread, slot, etc.. The cutting tool can be divided into integral turning tool, welding tool, machine tool, indexable tool and shaping tool according to the structure. Among them, the application of indexable turning tools is becoming more and more widespread, and the proportion of indexable tools is increasing gradually. The so-called turning tool two, welding type welding hard alloy, carbon steel rod is in according to the requirements of cutting tool geometry out groove, solder hard alloy blade is welded on the cutter groove, and according to the geometric parameters of the selected tool edge grinding after use. Three. The machine tool for clamping machine tool is a lathe tool, which is made of ordinary blade and clamped by machine. The utility model has the following characteristics: (1) the blade is not welded by high temperature; the defects of the hardness of the blade and the crack caused by welding are avoided, and the durability of the cutter is improved. (2) because of the increase of tool durability, the use time is long, the tool changing time is shortened, and the production efficiency is improved. (3) the knife rod can be used repeatedly, saving steel and improve the utilization rate of the blade, the blade by the manufacturer recycling, improve economic efficiency, reduce the cost of tool. (4) after the blade is re grinding, the size will gradually become smaller. In order to restore the working position of the blade, the adjusting mechanism of the blade is often arranged on the turning tool to increase the number of regrinding of the blade. (5) the end of the press plate used for pressing the blade can play the role of chip breaker. Four, indexable tool, indexable tool, is
