when producing the MC and TC with specified functions, e.g., for better
machining accuracy and heavier cutting.
In fact, the linear rolling guideway facilitates the ease of design and
manufacture of the machine tool. Nowadays, the conventional MC and
TC can be produced by designing them with the CAD and FEM; by pur-
chasing the servomotor, NC controller, linear bearing, and other neces-
sary parts and units; by in-house machining the structural body
component in certain cases; and by conducting in-house assembly. In
other words, a certain number of machine tool manufacturers worldwide
