シングル送りとマルチ送りとは？その違いは？ | オーエスジー

What is single feed and multi-feed? What's the difference?

Single feed is a pass type that processes one groove at a time, and is selected when the high quality of the screw is emphasized and the high hardness is supported.

Multi-feed is a pass type that processes multiple grooves at once, and is selected when machining efficiency is important.

* For single-point tools that process one groove at a time, multi-feed cannot be selected.
