锥柄的钻头、铰刀等刀具,都带有扁尾(图甲),在大量生产中,可在卧式铣床上用专门夹具来加工,生产效率当然很高。但在一般工具车间自制少量刀具,采用上述方法就反而不经济了。现在采用如图乙的简单工具,这工具只要求对边与锥孔同心即可。工作时,把工件的锥柄插入工具的锥孔内(图丙),用对刀样板对好位置,把工具夹在虎钳上,虎钳固定在立铣床工作台上。这样,纵向移动床面,由立铣刀来铣削工件上的扁尾,到一定长度后(可看纵向手轮的刻度来掌握),即可铣好一边;把铣刀退出,将夹具翻个,再用对刀样板对好,夹紧后即可铣另一边。由于工具的 Taper shank drill, reamer and other knives, with flat tail (Figure A), in mass production, horizontal milling machine can be used in a special fixture to process, of course, the production efficiency is high. However, in the general tool shop made a small amount of tools, using the above method is not economical. Now use the simple tool shown in Figure B, this tool only requires concentric with the tapered hole can be. Work, the workpiece taper shank into the tool taper hole (Figure C), with the knife on a good model position, the tool on the vise, the vise fixed on the milling machine table. In this way, the vertical movement of the bed, the end mill to mill the flat end of the workpiece, to a certain length (you can see the vertical scale of the hand wheel to grasp), you can milling side; the cutter exit, turn the fixture, Re-use the right knife model, after clamping can be milling the other side. Due to the tools
