Sherline ways are extruded, then ground(though this wasn't always the
case; early machines were just milled, and the earliest used the
extrusions as-extruded).

After this they DO use a surface hardening operation: the machine ways
are hard anodised.

MaxNC follows a similar approach.

Hope this helps,
