The aim of this article is to outline the progress of research into how to develop economically and scientifically justified backhoe bucket borehole renewal technology using mobile on-site manufacturing equipment. The novel boring machine is deployed directly on the excavator bucket and thus does not require the complete dismantling of the damaged unit. These machining operations should achieve superior results: the repair quality must be equivalent to the new product. Surface roughness, shape and tolerances should correspond to the manufacturer’s requirements. Comprehensive analysis is therefore required of the technological regime’s impact on surface integrity, supported by clear recommendations for the optimal choice of the technological regimes.
