The cost of CNC processing varies depending on the complexity and quantity of the parts. Generally, the cost of CNC processing a single piece will be relatively high because the startup cost and time cost of the machine need to be paid. For mass production, the cost of CNC processing will be relatively low because the startup cost of the machine can be spread over more parts.
For some simple parts, the cost of CNC processing a single piece may be only a few yuan, while some more complex parts may take more time and cost. Therefore, the specific CNC processing cost needs to be specifically evaluated based on the complexity and quantity of the parts.
