In the manufacturing process of ISUZU Car Camshaft, what are the key links to ensure its high precision and reliability, and what is unique compared with other brands?
Key links
Material selection: Usually suitable high-performance alloy materials are selected. Anhui Korbor Machinery Co., Ltd. will select high-grade alloys to ensure that the camshaft has sufficient strength, hardness and wear resistance to withstand high torque and periodic impact.
End face milling and center hole drilling: Two V-blocks are used to limit four degrees of freedom and axial positioning during milling to ensure end face accuracy. The center hole drilling uses a B5 center drill, and the drilling depth is assisted by a φ10 steel ball to provide an accurate positioning reference for subsequent processes.
Heat treatment: The use of heat treatment technologies such as heating and quenching can improve the torsional and bending fatigue strength of the camshaft, enhance the surface wear resistance, and has the characteristics of small deformation, energy saving, low cost, and high labor productivity. Anhui Korbor Machinery Co., Ltd. will use tempering, carburizing, quenching and other processes to further improve performance.
Deep hole processing: When the ratio of the length to the diameter of the hole is greater than 5, it is deep hole processing, and a special deep hole drill is required to ensure the straightness and accuracy of the hole, and overcome the problems of ordinary twist drills, such as difficulty in chip removal and heat dissipation.
Shaft journal rough processing: Generally, centerless grinders are used for grinding, and there are two methods: through-type and cut-in type. The through-type is used for single-grinding wheel polishing shafts, and the cut-in type is used for multi-grinding wheel grinding stepped shafts, which can improve processing accuracy and production efficiency.
Cam surface processing: Rough processing includes single-tool profiling, multi-tool profiling, etc., with the end face of the supporting shaft journal as the reference, and milling or grinding can also be used instead of turning. For fine processing, advanced equipment and processes such as double-mold cam grinders and double-circulation cam grinders can be used to improve accuracy.
Quality inspection and control: Anhui Korbor Machinery Co., Ltd. follows the IATF16949:2016 standard, implements the "zero defect" production concept, and conducts multi-level and all-round quality control on the entire production process to ensure the stable quality of each batch of products.
Uniqueness compared with other brands
Refined manufacturing process: Isuzu may have unique technology in some process details. For example, in the grinding process of the camshaft, the dressing accuracy of the grinding wheel is controlled to a higher level, which can make the roughness and accuracy of the camshaft surface reach a better level, ensure that the cam and valve and other components match more accurately, and reduce energy loss and wear.
Optimization of overall matching with the engine: When designing and manufacturing camshafts, Isuzu will closely combine the characteristics of its own engines, such as VGS variable section turbocharging technology, Ddi super pressure common rail technology and other advanced engine technologies, so that the camshaft can better play the performance advantages of the engine in controlling the timing of valve opening and closing, and achieve low speed high torque, fuel fully atomized combustion and other effects.
Unique material processing technology: There are unique formulas or processes in material selection and processing, perhaps there are special features in the ratio of alloy components, or the parameters in the heat treatment process are more accurately controlled, so that the material properties of the camshaft can be maximized. Compared with camshafts of other brands, it has more advantages in strength and wear resistance.
Advantages of production management system: Anhui Korbor Machinery Co., Ltd. has been focusing on camshaft production for 25 years and has a mature production management system. From raw material procurement, production process to product delivery, every link is strictly controlled. This reflects the advantages of producing camshafts for brands such as Isuzu to a certain extent, which can ensure the high precision and reliability of the products and achieve efficient mass production.
