MOBILE LINE BORING
What is Line Boring?
Line boring is a precision machining process used to restore worn, elongated, or damaged bores found in heavy equipment. Over time, pins and bushings wear, causing bores to become oversized or out of round. This wear leads to excessive movement, accelerated component failure, and reduced machine performance.
Line boring restores these critical connection points by machining the bore back to precise dimensions and installing the correct bushings or repair sleeves when necessary.
