摘要： PROBLEM TO BE SOLVED: To improve strength against breakage in tapping or manufacturing a tap by improving the rigidity of a small-diameter tap and dispersing the stress concentration.
SOLUTION: Since an intermediate shaft part 14 having a medium diameter dimension D
2 is provided between a working part 16 and a shank 12, while the projection dimension of the working part 16 is secured, the length of a small-diameter working part 16 is reduced to improve the rigidity, and bending deformation in pressing a grinding wheel to grind a male screw 22 is restrained to enhance the strength against breakage. Thus, the yield in manufacture is improved, and the pressing force of the grinding wheel is enlarged to heighten the working efficiency. Since the number of thread ridges of a rise part at the back end of a male screw 22 is set to three, the stress concentration in the rise part 28 is dispersed to enhance the strength against breakage, so that breakage in tapping is restrained in combination with the improvement in rigidity due to the existence of the intermediate shaft part 14 to improve the durability.

摘要翻译：要解决的问题：通过提高小直径龙头的刚度和分散应力集中度来提高攻丝或制造龙头中的断裂强度。解决方案：由于在工作部分16和柄12之间设置具有中等直径尺寸D 2 的中间轴部分14，同时确保工作部分16的突出尺寸，减小了小直径加工部16的长度以提高刚性，并且抑制了压制砂轮以研磨外螺纹22的弯曲变形，以提高抗破裂强度。因此，制造中的产量提高，并且砂轮的按压力被扩大以提高工作效率。由于阳螺纹22的后端的上升部的螺纹脊的数量为3个，所以上升部28的应力集中分散，提高强度而不破裂，从而能够组合地抑制攻丝破损随着中间轴部14的存在而提高刚性，提高耐久性。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To suppress breakage or chipping by preventing biting of chips, and to improve a life span of a tool, in a tap covered with a hard coating. SOLUTION: Though the hard coating 28 is provided on a surface of a screw portion 12, the hard coating 28 is removed in a straight groove 20 including a cutting face 32 of a cutting edge 22 and a tool base material 24 is exposed, so that chips sliding with the cutting face 32 becomes easy to be wound. Therefore, chipping or breakage due to biting is suppressed. On the other hand, if the hard coating 28 of the cutting face 32 is removed, cutting surface wear may be accelerated. However, when the life span of the tool is determined by dimensional accuracy of a female screw, generally, flank wear becomes more important than the cutting surface wear. A tip portion of the cutting edge 22 and the flank 30 continuing to that are structured by the hard coating 28, so that, according to this invention, the flank wear is suppressed, and breakage of the tool is suppressed. Consequently, the life span of the tool is increased as a whole. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To increase grinding efficiency and reduce manufacturing costs with a simple screw grinding operation. SOLUTION: At least one of base end flank faces and tip end flank faces of a plurality of complete threads 56 and continuous biting threads 60 is continuously ground across an entire axial direction of a screw part 10b by relative feeding a grinding wheel 26 to the screw part 10b in an axial direction using a first feed lead L1 relative to the complete threads 56, and a second feed lead L2 or a third feed lead L3 relative to the different biting threads 60. Therefore, at least one of both sides of the flank faces of the complete threads 56 and the biting threads 60 is ground at once, so as to simplify a screw grinding operation, heighten grinding efficiency, and reduce manufacturing costs.

摘要： PROBLEM TO BE SOLVED: To prevent blade chipping or breakage due to biting of chips more effectively when a perfect ridge section is screwed in a threaded hole formed by a chamfer section. SOLUTION: Since chamfering 30 is formed in the cutting blade 28 of the shank side ridge section 24b of the perfect ridge section 24, chips are easily pushed out to the peripheral side and entanglement of the chips to the perfect ridge section 24 is suppressed, and moreover, the strength of the cutting blade is enhanced by the chamfering 30. Since the lead of a helical groove 20 is gradually increased toward a groove dead end from a tap front end, the rake angle of the cutting blade 28 of the chamfer section 22 can be enlarged, and excellent sharpness of the blade can be obtained. Moreover, while the chips are curled small, they are guided to the helical groove 20, and discharged to the shank side smoothly. That suppresses entanglement of the chips to the perfect ridge section 24, and prevents blade chipping or breakage due to biting of the chips in cooperation with the existence of the chamfering 30.

摘要： PROBLEM TO BE SOLVED: To provide a coated tap with a hard film, which has the long life and shows stable machining capability by inhibiting welding from occurring on a stainless steel which is a material to be machined and tends to cause welding, even when tapping the material with the use of a chlorine-free water-miscible cutting oil.
SOLUTION: This tap has a Cr-containing base layer 32 having high hardness and low friction coefficient provided on the surface of the base metal in a neck part 14 and a thread part 16 of a spiral tap 10 in a tool 28, and a DLC film 34 having lower friction coefficient than the base layer 32 and excellent lubrication properties coated on the Cr-containing base layer 32. Then, the tap shows excellent welding resistance and abrasion resistance. The tool can tap the stainless steel which is the material to be machined and tends to cause the welding, while showing the stable machining capability and inhibiting the welding even when tapping the material with the use of the chlorine-free water-miscible cutting oil, and can extend the life.

摘要： PROBLEM TO BE SOLVED: To provide a thread cutter which can prevent formation of burrs at an opening edge of an internal thread. SOLUTION: According to the structure of the thread cutter, a helical flute 22 forming a cutting edge 16 is twisted leftward, in a manner being opposite to a cutting rotational direction (rightward) as viewed on the side of a shank 12, and therefore a rake angle of the cutting edge of a rear flank located close to the shank 12, out of a pair of flanks of a thread ridge 20, formes an acute angle, which contributes to improved sharpness of the cutter, to thereby prevent formation of burrs at an incomplete ridge portion at the opening edge of the internal thread. Particularly, a helix angle of the helical flute 22 is set to 5° or more, and therefore the sharpness of the cutting edge of the rear flank is positively improved. Further the helix angle is set to 30° or less, and therefore the cutter has a predetermined rigidity imparted thereto against toppling. Thus the accuracy of the internal thread is improved as a whole coupled with prevention of burrs. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供一种能够防止在内螺纹的开口边缘处形成毛刺的螺纹切割器。解决方案：根据螺纹切割机的结构，形成切削刃16的螺旋形槽22以与柄12侧面的切割旋转方向（向右）相反的方式向左扭转，因此，在螺纹脊20的一对侧面中位于靠近柄12的后侧面的切削刃的前角形成锐角，这有助于提高切削刃的锋利度，从而防止形成在内螺纹的开口边缘处的不完整的脊部处产生毛刺。特别地，螺旋槽22的螺旋角被设定为5°以上，因此后侧面的切削刃的锐度被显着提高。此外，螺旋角设定为30°以下，因此切刀具有预定的刚性以抵抗倾倒。因此，内螺纹的精度总体上得到改善，同时防止了毛刺。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a spiral tap capable of smoothly discharging chips.
SOLUTION: The spiral tap includes a cylindrical extension part 18 having a smaller diameter dimension than a prepared hole diameter and provided so as to be projected in an axial direction by a predetermined projection amount L on a distal end side of a screw 16. A twist groove 22 is provided on the outer peripheral surface of the extension part 18 so as to be extended from the screw 16. Therefore, mutual tangle of the chips discharged from the twist groove 22 is suppressed by the extension part 18, and the chips can be discharged in a fine state.
