In the machining process of UNKNOW automotive camshafts, how to ensure that the key parameters of the camshaft, such as profile accuracy, position accuracy and surface roughness, meet the design requirements?
1. High-performance materials and heat treatment process
The selection of materials is the basis. KORBOR uses high-performance alloy materials as the basis of the camshaft. These materials not only have high strength and good toughness, but also have excellent heat resistance and corrosion resistance, laying a solid foundation for subsequent precision machining and long-term use. Through a series of heat treatment processes such as tempering, carburizing, and quenching, KORBOR can greatly improve the intrinsic performance of the camshaft, including hardness, strength and wear resistance, ensuring its stability and durability in extreme working environments. This step is crucial to maintaining the profile accuracy of the camshaft in long-term use, because the increase in hardness can effectively resist wear and reduce profile deformation.
2. Precision machining technology and equipment
In order to ensure the profile accuracy of the camshaft, KORBOR uses advanced CNC grinding technology and high-precision machining centers. These devices use computer-controlled precise paths to perform micron-level contour processing on camshafts, ensuring that the key dimensions of each cam, such as shape, lift, base circle diameter, etc., are completely consistent with the design drawings. By adopting a closed-loop control system, the errors in the processing process are monitored and adjusted in real time, further improving the processing accuracy. In addition, KORBOR also uses online measurement technology to perform instant detection of the camshaft in processing, correct deviations in time, and ensure high stability of contour accuracy.
3. Guarantee of position accuracy
Position accuracy, that is, the relative position relationship between the key parts of the camshaft (such as journals, cams, etc.), is the key to ensuring the normal operation of the engine. KORBOR uses a five-axis linkage machining center and an advanced fixture system to ensure that all key parts are processed in one clamping, thereby minimizing the positioning error caused by multiple clamping. In addition, KORBOR also uses high-precision detection equipment such as laser rangefinders and three-coordinate measuring machines to perform full-size detection of camshafts to ensure that all key positions meet the design requirements, realizing all-round precision control from processing to detection.
4. Control of surface roughness
Surface roughness directly affects the friction characteristics, wear resistance and service life of the camshaft. KORBOR uses ultra-finishing technology and micro-abrasives to process the working surface of the camshaft to an extremely low roughness level through a fine polishing process. This process not only improves the smoothness of the surface and reduces friction loss, but also helps to form an effective lubricating oil film, further improving the wear resistance and operating efficiency of the camshaft. At the same time, KORBOR strictly controls the quality and ratio of the grinding fluid to ensure that no impurities are introduced during the processing process to affect the surface quality.
5. Quality management system and standard compliance
KORBOR follows the IATF16949:2016 international automotive quality management system standard and has established a complete quality management system. From raw material procurement, production and processing, testing to finished product delivery, every link implements multi-level and comprehensive quality control.
