Question about certain thread feature on a lathe headstock

Greetings,

I am disassembling a VDF 18RO lathe and on a few shafts bores in the headstock there are these seemly pointless holes. They are tangential to the bore thru which the shaft goes and they are a blind and countersunk M4 thread.

Any idea for their purpose? Are they used to help disassembly?

Shandong Sair Mechanical Guide company Experiences?

Hi everyone, I hope this wasnt asked before, atleast I could find any post. I am currently making a CNC machine for cutting steel and Im wondering has anyone came across the company Shangdong Sair?

They make linear rails and ballscrews at good prices and have good reviews on Alibaba but I havent seen much mention on Reddit or YT.

I would like to order rails and ball screws from them but I would like to be sure they are legit.
