Breakthrough in CNC Machining Technology of Forks for Forklifts of a Certain Tonnage: In-depth Integration of Heavy Load Capacity and Precision Manufacturing

Recently, there has been technological progress in the domestic construction machinery field. A certain intelligent manufacturing enterprise has successfully developed a dedicated CNC machining solution for the forks of forklifts with large tonnage through process innovation. This technology combines a five-axis linkage CNC machine tool with customized tool design to achieve the integrated molding of key structural components of the fork. The machining accuracy reaches 0.02mm, and it can withstand the impact test of goods with a load capacity of up to 30 tons. According to the technical team, traditional welded forks have defects such as stress concentration and large deformation. In contrast, the new solution uses a whole piece of alloy steel billet for milling. "We have reconstructed the topological structure of the fork." The project leader showed the 3D model. By optimizing the transition curve of the fork tip through finite element analysis, the uniformity of stress distribution has been increased by 45%. During the CNC machining process, a variable-diameter milling cutter is used in combination with the spiral interpolation process to ensure that the thickness tolerance of the fork arm is controlled within ±0.05mm. "The core difficulty of CNC machining of the forks of forklifts with large tonnage lies in balancing the material removal rate and structural strength." The engineer demonstrated on-site that the machine tool compensates for thermal deformation in real time through an infrared temperature measurement system, and cooperates with the precise spraying of nano-level coolant to effectively avoid vibration ripples during the machining process. According to the third-party inspection, after the finished fork undergoes a cyclic load test of 200,000 times, the deformation is less than 0.1mm. A certain logistics equipment enterprise has reported that after adopting this solution, the service life of the fork has been extended by 50%, and the failure rate has decreased by 78%. "Especially the curved surface design of the fork tip makes the grasping of goods more stable." The person in charge of warehouse operation and maintenance said that the precise positioning ability of the new fork has increased the loading and unloading efficiency by 30%. The enterprise has built an automated flexible production line, which supports the mixed-line production of forks with a tonnage ranging from 2 to 32 tons. The technical team revealed that they are developing an AI visual inspection system, which predicts the machining parameters through a deep learning model and promotes the intelligent transformation of CNC machining of the forks of forklifts with large tonnage. "This will completely change the current situation where heavy industry parts rely on manual grinding." With the industrial application of this technology, the independent supporting capacity of high-end forklift manufacturing in China is expected to be significantly improved, providing more reliable equipment support for scenarios such as intelligent warehousing and heavy-duty logistics.
