There are several methods for crankshaft machining, and the most suitable method can be selected according to the actual application. The requirements and characteristics of each application must be carefully evaluated before choosing the most competitive solution. On the principle of cost-effectiveness, the crankshaft is one of the most difficult workpieces to be machined. Because it is extremely asymmetrical, thin and long, the materials used are not processable, the quality control is very strict, and the manufacturing requirements are very high. The crankshaft is one of the core components of the internal combustion engine, ranging from small crankshafts for two-stroke engines for gardening equipment to giant crankshafts for marine diesel engines, of different sizes and shapes. Even the crankshafts in automotive engines are diverse, and each crankshaft is unique to the engine type and brand. As a mass-produced part, the production of automotive crankshafts is cost-effective and has undergone considerable evolution in design, materials and processing – with increasing demands for environmental protection, improved performance and lower manufacturing costs. This evolution will continue. Today's environmental pressures add more difficulty to the manufacture of crankshafts. The engine is gradually miniaturized and used in combination with a turbocharger to reduce exhaust emissions and minimize power loss. The evolution of the crankshaft has and will continue to promote the in-depth development of this feature. Today's truck engines are cleaner than the car engines of the early 1990s, and fuel efficiency has also improved significantly. In addition, the continuous development of crankshaft machining has made today's crankshafts more sophisticated without sacrificing the cost per piece. Some relevant industry standards can indicate people's expectations: the milling cutters that process automotive crankshafts typically do not exceed 0.02 mm. Tool life must be long and predictable to meet production schedules; the cutting edge must ensure high reliability between two tool changes (eg machining 8,000 crankshafts). The process time needs to be optimized to the second level to ensure the production per shift. Workpiece materials tend to use high-strength forged steel and increasingly use lighter, stronger austempered ductile iron (ADI). It goes without saying that both materials are more difficult to machine than traditional materials. Optimizing performance and machining results In order to optimize performance and machining results, the machining plan must be determined for each crankshaft. This requires close collaboration between crankshaft manufacturers, machine tool builders and tool suppliers. Sandvik Coca-Cola's Competence Centre, which is based in Germany, has an extraordinary track record: more than 900 tools have been used around the world. Sandvik Coca-Cola had already introduced non-standard milling cutters for crankshaft machining in the 1970s. By the early 1990s, it had accumulated enough technical production capacity to cope with the demand for crankshaft machining in the automotive industry. Turning and milling has also become a specialty of the center. Today, there are more than 70 million vehicles in the world each year. The need to improve engines to reduce emissions, reduce weight, and improve fuel economy is growing, and people are paying more attention to advanced crankshaft machining solutions. The necessary individual assessment of crankshaft evolution is an ongoing process, and successful solutions depend on careful and extensive analysis of many factors, such as throughput, process time, equipment requirements, processing levels, quality levels, tool change intervals, etc. There is no single standard solution that meets the requirements of all applications, all tailored to the application area that is not used. The crankshaft needs to be completed in several different processes. Forging blanks or casting blanks have different requirements for the machining process. The manufacturer's satisfaction with the process depends on his assessment of crankshaft unit production costs, production and investment costs. It is quite strong and stable when the crankshaft is mounted on the engine, but it is not suitable as a workpiece. Therefore, especially for the automotive industry, there are various methods for machining the crankshaft. Regardless of the processing requirements, Sandvik Coromant has extensively and intensively developed related tool designs, insert geometries and grades over the years to optimize the needs of different machining applications.
