Drill bits, as consumables, have a huge demand. Traditional drill bit manufacturing and new product substitution consume a large amount of strategic metal resources, and improper disposal of waste drill bits can cause environmental pollution. Laser cladding remanufacturing technology has demonstrated significant environmental benefits by giving old drill bits new life.
This article analyzes from the perspective of Life Cycle Assessment (LCA). In terms of energy conservation, the energy consumption of remanufacturing a heavy-duty drill bit is only 30% -40% of that of manufacturing a new drill bit, mainly saving in front-end processes such as ore smelting and rough forging. In terms of material saving: Remanufacturing uses old drill bit substrates as "blanks", with a material utilization rate of over 95%, requiring only a small amount of alloy powder consumption. Compared to new products, it can save more than 70% of materials. In terms of emission reduction, it avoids a large amount of CO ₂, SO ₂ emissions and wastewater discharge in the front-end production process.
In addition, laser cladding itself, as a near net forming technology, produces no toxic gases or waste liquids, and completely eliminates hexavalent chromium pollution by replacing traditional electroplating. Therefore, vigorously developing laser remanufacturing of drill bits is an inevitable requirement for the construction of a resource-saving and environmentally friendly society.
