To ensure pass centre precision, fixing adjusting washer precisely

between roller and rotating arm is needed and the user can

demarcate the dimension on the special carriage assembly lathe.

The roll press down of TRCM is a radial hydraulic roll gap adjusting

mode, so there is no need for washers as it only needs one time

pass centring during the pass machining so it is more easy to use

during the carriage assembly and maintenance process.

Lateral changing roll: The roll carriage changing taking lateral

changing roll mode is an improvement for the tunnel changing roll

mode. This is due to the tunnel changing roll mode not offerinf the

choice to change one stand singly or checking pass outside, causing

a great deal of inconvenience.

But lateral changing roll mode can offer a solution to the above

problems by using the hydraulic servo system to compensate for the

rigidity reduction caused by the moveable connection.
