What are the factors that affect the cost of CNC machining parts?

Many CNC processing manufacturers have been seeking ways to control processing costs as much as possible, and many users have also found that the quotations given by different companies for the same product are vastly different. What are the main reasons?
How can we better control the cost of CNC machining, regardless of factors such as factory size and location?
Next, let’s share with you which factors will affect CNC processing costs, and let’s learn more together.
01. Demand for precision machining equipment
Different production equipment will definitely have different prices, resulting in differences in labor costs. For example, there will definitely be a significant price difference between 200000 yuan of equipment and 2 million yuan of processing equipment.
Using multiple devices to complete a product, and using one device to use multiple functions to complete a product, because the processing functions of the equipment are different, the price may also vary.
For example, the cost of using a lathe and a CNC milling machine to process parts with a precision turning and milling machine must be higher than the cost of an Economy car turning and milling composite machine tool. However, if the lathe and milling machine are both small brands or older models, the opposite is true.
Some relatively large companies require high-precision testing equipment to assist due to the high product requirements of their customers, which invisibly increases the cost of equipment usage.
02. Dimensions and Shape of Parts
Precision parts with large volume and complex shapes require more materials, and the waste generated during processing will also increase, resulting in increased costs.
Some users have special requirements for the smoothness of the product, which will also increase the cost.
03. Post processing
Many users’ products require different post-treatment processes due to their different application fields, such as oxidation, oil injection, heat treatment, etc. These processes are also a factor in increasing product costs.
So, engineers need to conduct a comprehensive evaluation of the product and measure its cost-effectiveness when designing it.
In summary, if cost control is necessary, selecting appropriate precision machining processes, equipment, materials, post-processing, etc. is the best way to effectively control costs.
