I have had an original X2 Mill for a number of years, which is now in pieces whilst undergoing a long running conversion to CNC, including the longer base and solid column upgrade.

I need another mill and have been looking at the SX2P which seems generally well liked. However, looking at the exploded parts diagram on Arc's website I cannot see any sign of thrust races for the X and Y leadscrews. There appear to be just bearing blocks.

Can anyone enlighten me as to how leadscrew thrust is is handled on the these machines?

Thanks for the quick response.

I have just had a quick look at the SX2 parts diagram and it appears to retain the double row thrust bearings on the X-axis as also used on the original X2. both the X2 and SX2 had plain bearings on the Y-axis. (Both exploded parts diagrams have the axis incorrectly labeled!). It would appear that the thrust bearings were dropped on the current SX2P version.

As I have not seen any adverse comments regarding the operation of the X-axis leadscrew I will assume it is satisfactory and not put me off ordering one.

When I have a moment I will post a bit about the current problem I have with the CNC conversion of the X2 and will be interested to know if any one else has encountered the same issue.

My X2 definitely has thrust bearings on the X-axis and its quite old. Arc's X2 (Old X2 Mini Mill Spares) page shows the bearings. I know there were quite a few variations of this mill, mine's a Warco Mini Mill, but as far as I know they all had thrust bearings on the X-axis.
