Product Introduction
The CNC line boring and welding machine for construction machinery is a professional 2-in-1 integrated processing equipment independently developed for the maintenance and remanufacturing of heavy construction machinery. Combining precision CNC line boring and automatic bore overlay welding functions in one compact unit, this multifunctional machine perfectly solves the problems of hole wear, eccentricity, deformation and pin hole damage of engineering equipment.Different from traditional split boring and welding equipment, our CNC boring and welding all-in-one machine adopts full digital CNC control system, realizing one-time positioning and dual-process processing of boring and welding. It is widely applicable to on-site maintenance and factory remanufacturing of excavators, loaders, cranes, bulldozers and other construction machinery. With high processing precision, stable operation and strong portability, it greatly improves the efficiency of mechanical hole repair, reduces maintenance costs, and is an essential core tool for construction machinery maintenance factories, mining engineering teams and equipment leasing companies.
