Can I use WD40 or similar spray as a lubricant for the milling bed ?

David, to be a little more blunt than the other replies, who are being kind:

WD40 is closer to being a 'degreaser' than it is a 'lubricant'.

Order some Vactra #2 Way Lube, www.use-enco.com is as good a supplier as
any for this, apply it liberally and often.

If your machine is made in China, be sure to clean the casting sand and
other spooge out of any moving parts before you fire it up the first
time. That includes the miserable crap they apply where greases are
supposed to be - put Mobil 1 synthetic grease there.

Make sure your machine spins smoothly across the whole range of speeds
with no workpiece mounted.

Then get some chunks of known metal (6061 aluminum and 12L14 steel are
good choices) and start turning them into chips. You will learn enough
from that to know what to Google for. Have Fun!
