JP-A-3-184721 and JP-A-3-184
According to Japanese Patent Laid-Open No. 722, a screw can be cut on the inner peripheral surface of the hole while drilling, but the corner portion of the bottom blade is formed at a right angle or an acute angle. Since the mechanical strength becomes smaller as the angle of the corner becomes sharper, the corner is likely to be damaged during drilling. Further, since the screw cutting blade has no rough blade, there is a problem that the cutting resistance during tapping is large and the screw precision is poor.

The workpiece W is fixed, and the base end portion of the end mill body 1 is attached to the spindle of the cutting machine. Then, when helical feed is performed in the axial direction (1 pitch feed per revolution) while rotating the end mill body 1, first, the corner portions of the bottom blade 6 and the outer peripheral blade 7 at the tip of the end mill body 1 are the workpieces. Upon hitting W, the prepared hole 8 is then formed in the workpiece W by cutting the bottom blade 6 and the outer peripheral blade 7.

ので切り屑排出が改善される。At this time, since the bottom blade 6 has the mountain-shaped recess 5 formed at the bottom of the end portion of the end mill body 1 and is provided on the inclined surface thereof, the entire width of the bottom blade 6 simultaneously contacts the workpiece W. There is no contact, and one part contacts on one side and the other part does not contact. On the other hand, the outer peripheral blade 7 comes into contact with the workpiece W on the opposite side of the end mill body 1 with respect to the axis, and does not come into contact with the other side. Therefore, the contact length at the bottom is shortened and the cutting resistance is reduced.
The chip discharge is improved because it rises along the chip discharge portion 4 in the state of being divided into two parts.

Further, as the helical feed of the end mill body 1 progresses, the thread cutting traces cut by the rough blade 3a are removed by the finishing blade 3b,
It is cut by 3c and the complete thread 9 is processed.

工できる。After the inner peripheral surface of the prepared hole 8 is thread-cut by the rough blade 3a of the screw-cutting blade 3 as described above, the thread cutting marks are cut by the finishing blades 3b, 3c.
The pitch error of the screw to be cut is eliminated, high-precision machining can be performed, and the substantial cutting amount of the finishing blades 3b and 3c is small, so that the cutting resistance is small and smooth cutting can be performed.

Further, the screw cutting blade 3 is provided with one rough blade 3a and two finishing blades 3b, 3c, but the number thereof is not limited to the above embodiment.

外周刃を設けたことを特徴とする。According to the present invention, a thread cutting blade is provided on the side of the tip of the tool body, a recess is formed on the bottom, and a bottom blade is provided. It is characterized in that an outer peripheral blade is provided which is continuous with the bottom blade at an angle larger than 90 ° and is continuous with the outer peripheral portion at an angle corresponding to the thread cutting blade.

精度の高い加工ができるという効果がある。Therefore, a screw can be cut on the inner peripheral surface of the hole while making a hole in the work piece, and the cutting length is small because the contact length of the bottom cutting edge is short, and the chips are cut into pieces. This has the effect of improving the dischargeability of waste. At least one of the thread cutting blades on the tip side is a rough blade,
On the other hand, by using the finishing blade, the substantial cutting amount of the finishing blade is reduced, so that the cutting resistance is small, and it is possible to smoothly perform machining with high screw precision.
