Product Description
Our small line bore machine can be used as a portable line boring machine specifically designed for on-site bore repair in confined or hard-to-access areas. It is an efficient solution for restoring worn, elongated, or misaligned bores directly on equipment, without dismantling or transporting heavy components to a workshop.
As a compact in situ line boring solution, this machine is ideal for small to medium bore applications which is commonly found in excavators, loaders, attachments, and structural assemblies. The lightweight and modular design allows onsite machinists to do fast setup at the job-site, it also maintains the required rigidity for accurate machining.
By performing portable line boring on-site, the small line bore machine helps maintenance teams and mobile repair service companies minimize downtime, reduce repair cost, and extend equipment service life.
