In the CNC machining industry, the machining of batch parts can show certain machining advantages, one of which is efficiency.
In CNC machining of batch parts, it is necessary to save time first, and the improvement of efficiency can reduce a lot of costs, especially time. In general, three-axis machines are less efficient when machining bulk parts. First of all, the workpiece needs to be clamped several times. If the part has four edges and the entire workpiece needs to be machined with six sides, then six clamping passes are required.
Frequent clamping of workpieces takes up a lot of time without considering machining efficiency, and multi-sided machining requires more machines. If you encounter a surface that is not easy to process, you need to make a special jig to cooperate with the processing, which is not ideal from the perspective of cost and efficiency. However, five-axis simultaneous machining solves many problems. First of all, when it comes to efficiency, five-axis CNC machining and clamping doesn't require that much effort.
Five-axis machining can complete the machining of multiple surfaces with only one clamping, which improves efficiency, reduces the pressure of CNC on-site clamping, and saves a lot of time and cost for fixture matching machining. Typically, a three-axis machine requires six clamping cycles to complete the machining of the workpiece, while a five-axis machine only needs two clamping to complete the machining of the entire workpiece.
Therefore, five-axis CNC machining has a clear advantage in terms of efficiency. Secondly, quality is also a key factor. On the premise of ensuring efficiency, batch parts must first ensure quality. In the event of a quality issue, the entire batch of parts may need to be repaired, or even scrapped in its entirety. Therefore, before improving efficiency, we must first ensure good quality.
Due to the high number of clamping times on three-axis machines, when machining multi-sided parts, there may be errors on the sides, such as improper connections or machining failures, and may even require external processing to complete the machining. On the one hand, this has nothing to do with the increase in costs, and on the other hand, it affects the quality of the parts.
However, in 5-axis CNC machining, some complex sides can provide a better cutting environment for the tool based on the angle change of the workpiece. Since there is no need to disassemble the workpiece for calibration, 5-axis machining greatly reduces errors when machining flanks.
In many complex structures that cannot be machined in three axes, five axes can also be machined according to changing angles, thereby reducing costs and ensuring the quality of the workpiece.
