soo... the kicker here is that the cl-20b is a bank seizure and I might be able to get it for only 7k if the bank accepts... however no chip conveyor... it also does not quote a tool measuring system, and I am unsure if this is something that came standard or not.
The major difference is the Z travel, and I will be honest I could end up using the extra travel... I would really be cutting it close with that smaller unit but... I would probably make due with the lesser travel with that much of a savings. I noticed on the videos that these lathes tend to move on the Z past the chuck... so I assume that when it says travel is 12.2", the usable travel is actually less than this... ??
AL-2 comes with a tail stock... but does not mention coolant system... i would find it odd that there is no coolant system, anyone know if that is standard?
I have not used a lathe before... so I am a little confused with the designs for the chip conveyor... it looks like chips just fall out the bottom of the machine... so how is the coolant re-captured? and what happens to your part after you part it off... does it go into the conveyor and disappear?
Open to suggestions.... these seem like good prices to me. Both machines seem to be in good shape.
