Share some of the parts we do in the automotive field, we use precision five-axis cutting technology, first-class CNC system and efficient production process, to undertake the machining task of the core parts of the engine. The precision and performance of the components have reached the top level of the industry, providing strong support for the powerful output of the automotive power system.
Impeller processing has high precision requirements, so how do we do it?
The following are some methods to improve the machining accuracy of the impeller:
Equipment and tools
• Use of high-precision machine tools: high-precision CNC machining centers can provide a stable working platform for impeller machining, with good rigidity and high positioning accuracy, which helps to reduce machining errors.
• Precise tool system: The selection of high-precision tools and tool handles, such as hot-loaded tool handles, can improve the clamping accuracy of the tool and reduce the tool runout. The tool should be replaced in time after wear and the accuracy of the tool should be checked regularly.
Process planning aspect
• Optimize the machining path: in the programming stage, reasonably design the tool path. For example, for the processing of impeller blades, equidistant ring cutting or contour machining paths are used to avoid sharp tool steering and frequent acceleration and deceleration, reducing processing errors.
• Reasonable cutting parameters: According to the impeller material and tool performance, select the appropriate cutting speed, feed rate and cutting depth. For example, reducing the cutting speed and feed can improve the quality of the machined surface, but it will reduce the processing efficiency, and comprehensive considerations are needed to determine the best parameters.
Quality control aspect
• Online detection and compensation: using the measuring system of the machine tool or the probe installed on the machine tool, the key dimensions of the impeller are detected during the machining process, and the compensation value of the tool is adjusted timely according to the test results to correct the machining error.
• Multiple finishing: After the impeller roughing and semi-finishing, arrange multiple finishing processes to gradually reduce the processing allowance, so that the impeller size and shape accuracy gradually approximate the design requirements.
People and technology
• Operator skills: operators need to be skilled in machine tool operation and programming skills, able to make timely and correct judgment and treatment of problems in the process of processing.
• The use of advanced technology: such as the application of computer simulation processing technology, before the actual processing to simulate the processing process, predict the possible processing errors, adjust the process parameters and processing paths in advance.
