Tool is one of the most critical components in precision CNC machining. Choosing the right cutting tool can ensure the processing quality, efficiency and tool life. When selecting tools, the hardness, shape, size and other factors of the workpiece material should be considered, and the appropriate tool type, specification and geometric characteristics should be selecte.
When using the cutting tool, it is also necessary to pay attention to the setting of the cutting speed, feed speed, cutting depth and other parameters of the cutting tool to ensure that the temperature and cutting force generated during the cutting process are within the tolerable range.
Correct processing parameters can maximize the performance of machine tools and cutting tools, and improve processing efficiency and quality. Processing parameters include cutting speed, feed rate, depth of cut, number of cuts, etc. When setting processing parameters, factors such as the nature, shape, and size of the material need to be considered.
Before CNC machining, the workpiece needs to be fixed on the machine tool to ensure that no deviation will occur during machining. The operator should select the appropriate workpiece fixture, and determine the clamping force and position according to the shape, size and weight of the workpiece.
When fixing the workpiece, you also need to pay attention to safety issues. Fixtures should be strong enough to prevent the workpiece from moving or being thrown during processing, causing injury to the operator.
Equipment cleaning can prevent dust and impurities from causing damage to equipment; replacement of worn parts can ensure the service life of tools and other components; equipment calibration can ensure machining accuracy and stability; electrical inspection can avoid the impact of electrical failures on machine tools.
In short, CNC machining is a technology-intensive process that requires operators to be proficient in technology, good at innovation, and pay attention to details to ensure the quality and efficiency of processed products.
