Against the backdrop of the deepening lightweight strategy for new energy vehicles, a well-known new energy vehicle manufacturer faces a severe challenge: the high-strength aluminum alloy profiles used in its battery pack frame and body structural parts frequently exhibit precision deviations and surface quality issues during cutting. The cutting angle errors, burrs, and vibration marks generated during processing with traditional alloy saw blades not only significantly increase the workload of subsequent polishing processes but also lead to component misalignment during assembly due to accumulated dimensional errors, directly threatening the structural safety and assembly precision of the entire vehicle. Although the factory has attempted to adjust the cutting parameters, the results have been minimal, and the root cause points directly to the process compatibility between the cutting tool and the material.
The Bajun Cutting Tools technical team went deep into the production line and, through high-speed camera analysis and cutting morphology detection, accurately located the root cause: the rake angle design of the general-purpose saw blade could not adapt to the adhesion characteristics and heat dissipation requirements of the high-strength aluminum alloy, resulting in excessive cutting resistance and poor chip removal. Based on this, the team customized a systematic solution for them—using a low-internal-stress precision quenched steel matrix, combined with 15 a positive rake angle and a special tooth grinding process, effectively reducing cutting force and optimizing the chip removal path; a nano-scale aluminum nitride composite coating is applied to the surface, which improves wear resistance while significantly reducing adhesion; 60 the dense tooth design ensures the stability and surface smoothness of the cutting process.
After the implementation of the solution, the results were significant: the cutting angle error was stably controlled within ± 0.05mm , completely solving the problem of component assembly misalignment; the surface finish is close to a mirror effect, the need for secondary polishing is basically eliminated, and the one-time pass rate has increased to 99.5% ; cutting efficiency increased 20% , and tool life extended 3 times, resulting in a significant reduction in overall manufacturing costs. The customer's production manager commented: " Bajun Cutting Tools not only provided high-performance products but also, through professional technical diagnosis and process optimization, helped us overcome the key bottleneck in lightweight manufacturing. Their pragmatic and efficient service model is impressive. " This case vividly illustrates Bajun Cutting Tools' technical strength in providing customized solutions for high-end manufacturing, with a core focus on the deep integration of materials science and cutting technology.
