workhorse two-axis CNC lathe has been greatly improved by additional features, such as extra axes, sub-spindle, milling attachments, live tools, etc., the most important specifications still apply, regardless of the innovations.
FANUC SYSTEM SPECIFICATIONS
The following tables contain typical control specifications of Fanuc CNC system and are based on the 0i, 21i and 18i models. Keep in mind that control specifications generally show the maximum capabilities which are not always present for a particular machine tool.
Most of the specifications listed are common to both milling and turning controls, although each control type has features specific to the particular machine tool.
Use the tables as general reference only and consult machine documentation for exact specifications.
