Excavator Track Repair Tool Intelligent CNC Boring Welder Multi-Functional Line Boring Welder

This machine is a CNC automatic boring and welding integrated mechanical maintenance tool that can repair and machine the shaft holes and seat holes on the excavator's large and small arms. This product has high processing accuracy with a tolerance of 0.01mm.
Features: light weight, fast boring speed, strong power, easy operation, high efficiency, compatible with welding machines, easy to install in narrow workspaces, and low price.
Simply replace the boring bar and welding gun to achieve the alternation of repair welding and hole repair processes.
Boring bars are made of alloy steel with high precision strength and hardened. It is not easy to deform. The machine is controlled by industrial-grade intelligent chip with digital display of key parameters, easy to operate and more convenient to control remotely using remote control. Adopting optical control technology, automatic swing welding and skip welding function can be realized without programming. The equipment is suitable for the external repair of shaft holes in excavators, cranes, hoists and other construction machinery as well as ships.

Portable boring and welding integrated machine is a specialized tool for repairing shaft holes in construction machinery. The machine is lightweight, compact in structure, fully functional, stable and reliable in performance, with a high power to weight ratio. It is widely used for on-site processing and maintenance of shaft holes in large equipment, and is suitable for repairing out of roundness shaft holes in construction machinery such as excavators, cranes, and ships. Due to its lightweight and easy portability, it can be repaired on-site on construction sites, thus avoiding the cost of transporting large heavy machinery back to the workshop. It is an essential tool for engineering machinery maintenance and renovation!


The boring bar is made of high-strength alloy steel and quenched by process. Stress aging treatment, surface plated with hard chrome polishing, high precision and not easily deformed.The machine is controlled by industrial grade intelligent chips, with key parameters displayed digitally.


It is easy to operate and can be remotely controlled using a remote control for greater convenience. Using light control technology, automatic swing welding and skip welding functions can be achieved without programming.
