What should I do if the beads of rosewood lathe turn black?

I'm happy to answer your question:

? But the knife is not fast. Generally, big holes are black. Another possibility is that the speed is too fast and it is burnt. It doesn't really matter. It won't show up after a period of oxidation. If you especially hate that beads are black at both ends, it is recommended to change to a wood transfer shop for processing.

I hope my answer is helpful to you.
