However, manufacturing a rotary dresser with the same shape as the female screw has the problem of high manufacturing costs and Il!
Naturally, if the shape of the screw changes, it will be necessary to manufacture a new rotary dresser. Furthermore, dressing according to the present technology requires rotating and reciprocating the rotary dresser as described above, and it is generally difficult to increase the rotational speed and reciprocating speed, resulting in the problem that dressing takes time. .

研削用砥石のドレッシング方法を特徴とする。[Means for Solving the Problems] In order to achieve the above object, the present invention provides a dressing method for shaping the outer circumferential surface of a grindstone for grinding a female thread, in which a recess having the same cross-sectional shape as the groove cross-section of the female thread is formed on the outer periphery. The male dresser to be formed is tilted by the lead angle of the female thread, and while the male dresser is oscillated along the envelope of the effective diameter of the female thread, the lead is fed by an amount corresponding to the oscillation angle to drive the grindstone. The present invention is characterized by a dressing method for a grindstone for grinding an internal thread.

なる。[Function] By swinging and leading the male dresser, which has the same groove cross-sectional shape as the female thread, along the envelope line corresponding to the effective diameter of the female thread, the grindstone behaves as if it had been dressed with a female rotary dresser. Processing will be carried out.
［実施例］ 以下１本発明を図面に基づき説明する。[Example] The present invention will be explained below based on the drawings.

形成される。The effective diameter does not need to match the effective diameter of the female thread, and an appropriate diameter is set. Further, a hole 3 is formed through the dresser l for fixing the dresser l to the spindle of the circuit.

できまる包絡線に沿ってドレッサ１を移動させる。As shown in FIG. 4, the dresser 1 is arranged inclined by the lead angle. On the other hand, the grindstone 4 is arranged at an arbitrary angle as shown in the figure. The grindstone 4 is brought into contact with the dresser 1 and rotated at high speed. On the other hand, the dresser 1 is swung by an appropriate angle θ along a trajectory 5 corresponding to the effective diameter of the female screw, and
Grinding wheel 4 by the lead amount X value corresponding to the angle θ shown in FIG.
along the axial direction. That is, the dresser 1 is moved along the envelope defined by the trajectory 5 and the X value.

されることになる。Of course, this is carried out while the dresser 1 is rotating at high speed. The dresser 1 can be easily moved along the envelope line by using a helical interpolation function in a numerically controlled machine tool. Further, the dresser 1 may be moved by a special dressing device of the circuit.6 or above, the grindstone 4 is dressed in the same shape as if it had been dressed with a dresser having the same shape as the internal thread.
本実施例ではドレッサ１は雄型のものから作られ、雌型
のものに較べて製作は容易で、安価に作ることができる
。またドレッサ１は前記した如く。In this embodiment, the dresser 1 is made of a male type dresser, which is easier and cheaper to manufacture than a female type dresser. Further, the dresser 1 is as described above.

来る。Since the grinding wheel itself can be rotated at high speed, the grinding wheel 4 can be quickly and smoothly dressed, and as a result, good internal thread grinding is possible. Furthermore, in the case of a female rotary dresser, if the workpiece to be ground changes, the rotary dresser must also be changed accordingly, but in the case of this example, if the cross-sectional shape of the thread groove is the same, the effective diameter and lead of the thread One dresser 1 can be used even for different types.
