In the wave of lightweight manufacturing of new energy vehicles, a leading automaker encountered problems in the processing of aluminum alloy profiles. " Precision difficulties " The high-strength aluminum alloy profiles used in its battery pack frame and body structure frequently exhibited cutting angle deviations, burrs, and vibration marks during traditional saw blade cutting. This not only led to a sharp increase in subsequent grinding time but also caused slight misalignment in component assembly due to accumulated errors, posing a hidden danger to the overall vehicle structural stability. Although the factory attempted to make breakthroughs by adjusting cutting parameters, it failed to address the root cause of the problem.
Faced with this bottleneck that restricts production efficiency and product quality, the Bajun Cutting Tools technical team upholds " Precision and intelligent solutions " Going deep into the production line to conduct systematic diagnosis. By observing the cutting process with high-speed cameras and analyzing the chip morphology and saw blade status, the team accurately identified the problem: the rake angle design of the general-purpose saw blade did not match the material adhesion and heat dissipation characteristics of the aluminum alloy, resulting in excessive cutting resistance and poor chip removal, ultimately leading to double defects in cutting angle accuracy and surface quality.
Based on in-depth analysis, Bajun Cutting Tools customized " Material property matching " Solution: Using a precision quenched steel matrix combined with a low-stress design to ensure zero deformation during cutting; innovatively developing " Large rake angle ( +15 °) + Special tooth grinding " Compound tooth shape, while reducing cutting resistance, achieves smooth chip removal through an optimized chip groove structure; using nano-level AlTiN Multi-layer composite coating, giving the saw blade excellent wear resistance and anti-adhesion properties, combined with 60 Dense tooth layout to achieve fine cutting. After the implementation of the solution, the profile cutting angle error is stably controlled within ± 0.05mm The surface finish is close to a mirror effect, and the one-time pass rate has jumped to 99.5% Cutting efficiency increased 20% Tool life extended 3 times. Ultimately, the customized technical solution helped the customer overcome key technological challenges in lightweight manufacturing, demonstrating the professional depth and technical expertise of the original manufacturer in the field of material processing.
