摘要： PROBLEM TO BE SOLVED: To provide a thread shape more stable in threading than in the case of a metric coarse screw thread, excellent in strength, and also excellent in loosening torque after vibration is applied thereto in such a sheet and a thin-wall part that the current metric coarse screw thread can secure the number of threaded threads equal to three threads.
SOLUTION: In this thread shape for fastening the sheet or the thin-wall part, the value of the ratio (P/D) of the pitch (P) to the nominal diameter (D) of each of the coarse screw threads is reduced more than those of the coarse screw threads in various screw standards, and the number of threads is set to 2 or more lines.

摘要： PROBLEM TO BE SOLVED: To form a screw which performs a locking function without fail.
SOLUTION: A female screw material is pressed by a tool thread of a cold forming tap 1 to cold-form a pair of projected ribs while the ribs are drawn near to become like one thread. The thread is formed releasing at least one of the projected ribs to a relief part 9 ranging from a thread angle changing point CP to the vicinity of a bottom of thread groove 6, while the point CP locates between a point of effective diameter d2 on both flank faces 7, 8 of the tool thread and a point of the maximum female screw inside diameter allowance D1m of a female screw to be formed engaging with the tool screw. The female screw forming method is characterized in that a portion with a smaller thread angle than the regular angle is formed on the projected rib constituting both flank faces of the thread from the thread angle changing point closer to the thread top than the effective diameter to the vicinity of the thread top.

摘要： PROBLEM TO BE SOLVED: To provide a thread forming tap which increases a tool life by changing an increase in a screw size between a screw thread in a bevel lead. SOLUTION: In a bevel lead of a thread forming tap, an increase in a screw size between a screw thread has been constant. However, the drag in thread forming applied to the screw thread in parallel thread is large, which causes abrasion and reduces a tool life. The thread forming tap changes an increase in the screw size between the screw thread of the bevel lead to disperse the drag in thread forming applied to the screw thread, thereby reducing the abrasion of the screw thread and extending the tool life.

摘要： PROBLEM TO BE SOLVED: To provide a thread forming tap with a stable lifetime by preventing the threads of the tap from being chipped.
SOLUTION: The thread forming tap 1 has a screw part 2 with a tapered bevel lead 3 whose tip is narrower and a parallel screw part 4 continuous to the bevel lead 3. By making the thread top cut height of the bevel lead 3 higher than the thread top cut height of the parallel screw part 4, the thread forming resistance in a part near the intersection point of the bevel lead 3 and the parallel screw part 4 where chipping of the screw threads may be easily generated is reduced, so that chipping of the screw threads in the thread forming tap is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a cutting tap for cutting an internal thread of a material.SOLUTION: The cutting tap includes an elongate tap body (22) with a fluted section (30) at the axial forward end (24) thereof wherein the fluted section (30) includes a chamfered fluted section (54) and a finishing fluted section (56). Each cutting thread (58, 62, 66, 68) in the chamfered fluted section (54) has a cutting face (72, 76, 80) disposed at a cutting face angle that becomes more negative the more axially rearward the cutting thread (58, 62, 66, 68) is from the axial forward end (24) of the chamfered fluted section (54). Each cutting thread (58, 62, 66, 68) in the finishing fluted section (56) has a cutting face (72, 76, 80) disposed at a finishing cutting face angle that is essentially equal. The finishing cutting face angle is more negative than the cutting face angle for the cutting thread at the axial rearward termination of the chamfered fluted section (54).

摘要： PROBLEM TO BE SOLVED: To provide a center hole drill capable of carrying out hole cutting processing using the center hole drill under the same hole cutting processing condition as that of a conventional center hole drill, and reducing grinding time and manufacturing the center hole drill at a lower cost by reducing the grinding amount of the flank of a drill part and a counter bore part when manufacturing the center hole drill by reducing the runout amount of the flank arranged at the drill part and the counter bore part.
SOLUTION: The runout amount of the flank arranged at the drill part and counter bore part of the center hole drill is determined to an extent that the flank does not interfere with a material to be cut during hole cutting processing using the center hole drill. The runout amount of the flank arranged at the drill part and the counter bore part is not continued to increase from a cutting blade till a heel. The increase of the runout amount of the flank arranged at the drill part and the counter bore part is stopped on a half way between the cutting blade and the heel to generate a fixed value.

摘要： PROBLEM TO BE SOLVED: To provide a screw machining tool with an interchangeable screw machining portion in which a shank portion and the screw machining portion are positioned and fixed each other in two directions, namely the circumferential direction around the center axis line and the direction orthogonal to the center axis line, both directions being orthogonal to each other, and during machining of a female screw, play in the circumferential direction around the center axis line is extremely suppressed.
SOLUTION: A female connecting screw formed on one of the shank portion and the screw machining portion is screwed with a male connecting screw formed on the other. A truncated male conical taper surface formed on one of the shank portion and the screw machining portion is combined to abut with a truncated female conical taper surface formed on the other. The threading direction of a female screw to be machined by a cutting edge of the screw machining portion, and the threading direction of the male connecting screw and the female connecting screw formed on the shank portion and the screw machining portion are made the same. Furthermore, the shank portion and the screw machining portion are tightened up further by a bolt having the threading direction opposite to that of the female screw to be machined by the cutting edge of the screw machining portion, and the male connecting screw and the female connecting screw formed on the shank portion and the screw machining portion.

摘要： PROBLEM TO BE SOLVED: To provide a cold forming tap which improves a tool life through reduction of working torque.
SOLUTION: In a profile of a projected part of a cold forming tap, an exact round part (margin) is arranged to stabilize cold forming. The exact round part causes a larger friction resistance, which increases the working torque, causes occurrence of melting and sticking to the tap and affects the tool life. The new cold forming tap has a small relief angle in the part corresponding to the exact round part, which can reduce the working torque and extend the tool life.
