In the accelerating trend of lightweighting in the new energy vehicle industry, a leading automaker encountered technical bottlenecks in the processing of battery pack frames and body structural parts. The extensive use of high-strength aluminum alloy profiles resulted in frequent cutting angle deviations, burrs, and chatter marks on the cutting surface when using traditional saw blades. This not only led to low efficiency in subsequent polishing processes but also affected the overall vehicle structural stability due to accumulated errors, becoming a bottleneck restricting production improvement. Faced with this common industry problem, the Bajun Cutting Tools technical team went deep into the production line and conducted a systematic analysis of the cutting process and saw blade status using professional instruments, accurately locating the root cause: the rake angle design of the general-purpose saw blade was mismatched with the stickiness and thermal conductivity of the aluminum alloy material, resulting in excessive cutting resistance and poor chip removal, thus affecting processing accuracy and surface quality.
Based on in-depth diagnosis, Bajun Cutting Tools developed a customized technical solution: using a high-stability precision quenched steel substrate, combined with a large rake angle (+15°) and special tooth design optimized for the characteristics of aluminum alloys, significantly reducing cutting resistance and forming a smooth chip groove; selecting a nano-level AlTiN multilayer composite coating to give the saw blade excellent hardness, red hardness, and anti-stickiness, combined with a 60-tooth fine-tooth configuration, to achieve fine and stable cutting. After the solution was implemented, the profile cutting angle error was stably controlled within ±0.05mm, the surface finish was significantly improved, the one-time pass rate reached 99.5%, the cutting efficiency increased by 20%, and the tool life was extended by 3 times. The customer's production manager commented: "Bajun Cutting Tools, with its professional technical diagnosis and customized solutions, not only overcame our processing difficulties but also provided strong technical support for the lightweighting strategy of new energy vehicles." This case demonstrates the technical strength of Bajun Cutting Tools as an original equipment manufacturer—by deeply understanding customer application scenarios and material characteristics, empowering customers to achieve excellent manufacturing through precise technological innovation.
