Portable Boring Machine

The portable boring machine is a on-site maintenance tool for engineering, energy and chemical equipment, mainly machining small pipeline inner holes and concentric spaced holes—widely used in excavators, cranes and other construction machinery. It applies to post-weld machining of rotary/hinge/pin holes, bushing installation after hole enlargement, and concentric hole repair, supporting one-time positioning for multi-hole coaxiality. Operable by one person, it’s designed for on-site needs, reducing operation difficulty and boosting maintenance efficiency.
