herramientas CNC<\/a> play a crucial role in automotive manufacturing, where many processes require specialized and composite tools. For instance, in the machining of engine crankshafts, whether it’s internal milling, turning, or high-speed external milling, specialized tools are utilized. These tools have complex manufacturing processes and high technological content, placing high demands on tool manufacturing enterprises in our country. Below are two aspects elaborating on the application of CNC tools in the automotive manufacturing industry<\/p>\n

The cylinder block is one of the crucial components of an engine, made of either cast iron or aluminum-silicon alloy, each with different machining properties. For example, when machining gray cast iron, ductile iron, and high-density ductile iron, these cast irons exhibit different machining characteristics. Gray cast iron contains a networked hard structure, resulting in brittleness, making the tools prone to edge chipping during machining. Ductile iron and high-density ductile iron have certain plasticity, producing iron chips during machining, but there’s also the risk of workpiece burrs, leading to tool tip damage.<\/p>\n

Aplicaci\u00f3n de herramientas s\u00f3lidas CNC en el mecanizado de cig\u00fce\u00f1ales<\/p>\n

Characteristics of Crankshaft Machining Today’s market demands smaller engines from automobile manufacturers while requiring higher power and speed, increasing the load and stress on crankshafts. Manufacturers continually seek stronger materials for these parts, usually including high-alloy metals. Ductile iron is the standard material for lower-load engines (mostly gasoline engines), while high-horsepower engines (including most diesel engines) use more expensive alloy steel forgings. The steel grades used for crankshafts usually undergo various heat treatments, such as quenching and tempering. In some special high-end applications (including racing), crankshafts may be machined directly from round steel. Due to the specific characteristics of crankshaft structure, most domestic passenger car crankshaft production lines are high-speed flexible production lines (FTL), which can not only process the same series of crankshafts but also variant products, generation products, and new products.<\/p>\n

M\u00e9todos de mecanizado del cig\u00fce\u00f1al<\/h2>\n

Una forma sencilla de mecanizar los extremos y mu\u00f1ones de un cig\u00fce\u00f1al es girando en tornos o centros de torneado tradicionales. Obviamente, esto requiere suficiente espacio entre el portaherramientas y la superficie mecanizada del mu\u00f1\u00f3n. Los beneficios de este m\u00e9todo incluyen la capacidad de utilizar m\u00e1quinas herramienta, herramientas e insertos est\u00e1ndar para una alta flexibilidad y bajo costo. Una m\u00e1quina herramienta dedicada con capacidades de torneado y torneado puede mecanizar los mu\u00f1ones en el centro de rotaci\u00f3n del cig\u00fce\u00f1al. Se pueden instalar insertos de corte para mecanizado de desbaste y acabado en el mismo disco de herramienta, completando una carrera de corte de forma especial de una sola vez. Otros beneficios incluyen repetibilidad, buena calidad de la superficie de mecanizado, tolerancias m\u00e1s peque\u00f1as, mayor vida \u00fatil de la herramienta, menor frecuencia de cambio de herramienta para una mayor utilizaci\u00f3n de la m\u00e1quina herramienta y menor tiempo de mecanizado, etc. La desventaja del torneado es el mayor costo de las m\u00e1quinas herramienta y herramientas dedicadas, como as\u00ed como la necesidad de una gran cantidad de insertos. Un m\u00e9todo de torneado m\u00e1s especializado es utilizar insertos de torneado de dientes m\u00faltiples para controlar los esfuerzos de rotura de viruta y evitar acciones de giro.<\/p>\n

Debido a la estructura especial de los cig\u00fce\u00f1ales de los motores, la mayor\u00eda de las l\u00edneas de producci\u00f3n de cig\u00fce\u00f1ales para autom\u00f3viles de pasajeros nacionales son l\u00edneas de producci\u00f3n flexibles (FTL) de alta velocidad, que no solo pueden procesar la misma serie de cig\u00fce\u00f1ales sino tambi\u00e9n productos variantes, productos de generaci\u00f3n y productos nuevos.<\/p>\n

Selecci\u00f3n de herramientas CNC para mecanizado de cig\u00fce\u00f1ales<\/h2>\n

For machining the main journal of the crankshaft, CNC internal milling or CNC high-speed external milling should be preferred, while CNC high-speed external milling should be used for connecting rod journals. If the blank is forged steel, CNC internal milling is more conducive to chip breaking. CNC turning and turning should be avoided. Due to intermittent cutting on the side of the counterweight and high crankshaft speed (about 1000r\/min), tool chipping is severe. According to the characteristics of our company’s products, we have significant advantages in the machining of crankshaft end face threaded holes, straight oil holes, and inclined oil holes. Currently, our company’s solid tools have been widely used in Shanghai Volkswagen, SAIC Motor, and General Motors.<\/p>\n

Milling cutter bodies and modules are made of carbide\u00a0to increase the overall hardness of the machine body, thereby improving the tool’s lifespan. Inspection and fixtures for milling cutters. Products are tracked and inspected using a projector and ruby measuring head, and some fixtures are made.<\/p>\n

The produced milling cutter profile tolerance is \u00b10.03mm, radial runout is 0.05mm, and end face runout is 0.04mm. Under cutting conditions with cutting speed V=150m\/min and feed rate s=200mm\/min, normal use is achieved. It can be seen that the designed milling cutter profile meets the user’s accuracy requirements and improves machining efficiency.<\/p>\n
