転造タップでのバリ対策とは？ | オーエスジー

The cause of burrs in the forming tap can be the shape of the pilot hole, the lubricity of the cutting oil, and the cutting data. Please check the following points.

Pilot hole

・Finish of pilot hole diameter

・ Is the bend of the pilot hole and roundness bad?

・Conditions for pilot hole processing (drilling)

Tapping

- Are the tap conditions appropriate?

・ Is the selection of forming tap appropriate?

・Is the cutting oil applied properly?
(It is also effective to increase the lubricity of the cutting oil (if it is water-soluble, thicken the concentration of the oil))
