Dongguan CNC four-axis machining quotation
When doing four-axis CNC machining in Dongguan, people are often confused by the bunch of numbers on the quotation. No one knows what money must be spent and what money can be saved. Today I am here to explain this issue to you all at once.
The prices vary several times depending on the materials.
Since 2024, the price of 6061 aluminum alloy raw materials has been fluctuating in the range of 18,000 yuan to 22,000 yuan per ton, while the price of 304 stainless steel has been stable between 12,000 yuan and 15,000 yuan. As for engineering plastics such as PC and ABS, the cost is only tens of yuan per kilogram, so if the same part is made of another material, the price difference can be as much as two or three times.
In the Chang'an and Humen areas of Dongguan, when factories engaged in CNC processing make quotations, the cost of materials usually accounts for a large proportion of the total cost. The specific situation is generally between 30% and 50%.
If the product you produce is only used as a functional component and does not have any special requirements for the external appearance, then you can consider using aluminum alloy instead of stainless steel. In this way, the cost of processing can be significantly reduced, which can be said to be able to cut off a considerable part of the expenditure.
The higher the accuracy, the more expensive the work hours are.
Normally, four-axis machining equipment can achieve an accuracy standard of plus or minus 0.01 mm. However, if you want to achieve a higher level of precision of plus or minus 0.005 mm, you need to redesign and plan all key elements such as tool paths, clamping methods, and cooling plans. In addition, the working time in the entire processing process will definitely increase by at least 40%, so the final quotation will naturally increase accordingly.
At this point in time in 2025, many factories in Dongguan have successively launched plans to use five-axis linkage technology to replace some four-axis machining processes. However, it needs to be pointed out that when dealing with business involving specific parts such as stepped shafts and turbine blades, the four-axis solution is still the most cost-effective and cost-effective option at the moment. Regarding the billing method for pure processing costs, The general market price in the industry is usually based on the calculation and charging range of RMB 300 to RMB 800 per hour.
The quotation logic for batches and single pieces is completely different.
The difference between making five hundred pieces and making five pieces is far more than just a matter of unit price. The cost of programming, first-piece confirmation fees, and replacement materials are all fixed costs once incurred. These fixed costs need to be allocated to each part. If quoted for a single piece, the price may reach three to five hundred yuan. Only after mass production can the price of a single product be forcibly reduced to tens of yuan.
The method adopted by several medium-sized factories in Songshan Lake and Dalang, Dongguan is to give bulk prices when the quantity reaches 100 pieces and above, and when the quantity exceeds 1,000 pieces, an additional 20% discount will be provided. If you only ask for a quotation with a 5-piece set, the other party will directly calculate the cost based on the working hours of a single product, so there is no loss at all.
Don’t miss out on surface treatment
For processing methods such as anodizing, electroplating, and sandblasting, the cost of each part usually reaches tens to hundreds of yuan.
Therefore, when many customers see the quotation of CNC-processed bare parts, they often feel that the cost is relatively low. However, when the total price of the surface treatment they require is also included, the final total amount will be doubled, resulting in a direct overrun of the overall budget.
In 2025, the price of anodizing treatment in Tangxia, Dongguan will be roughly 0.5 yuan per square decimeter, or up to 1.5 yuan. In addition, the cost of electroplating nickel is about 0.3 yuan to 0.8 yuan per gram. When you get the quotation, remember to confirm with the salesperson whether the surface treatment work is included.
The rush fee is more severe than you think
The normal delivery time is in the range of 7 to 15 working days. If you want to hand over the goods in three days, the factories in Dongguan will charge an additional 30% to 50% for expediting. This happens because orders need to be inserted and shifts need to be adjusted, so the labor costs and the cost of machine tool occupancy all go up.
In the first half of 2026, there are many factories in Dongguan, and their order schedules have been stretched to more than twenty days. Therefore, if you want the order to be processed expedited, it is best to confirm with the colleagues in charge of the business a week in advance.
The approximate range of Dongguan quotation
Now many people are asking about four-axis CNC machining in Dongguan. The pure processing fee is about 200 yuan to 600 yuan per hour. If you encounter complex parts or parts that require high precision, the cost will be higher, which can reach about 800 yuan to 1,200 yuan. If the material cost and surface treatment cost are included together, take a medium-complexity part. The total price usually fluctuates between 500 yuan and 5,000 yuan.
At this point in October 2026, I contacted several factories in Humen and Chang'an. Aluminum alloy aviation parts of the same specifications processed by these factories. The prices range from 1,200 yuan to 2,800 yuan. The reason for this relatively large gap. It mainly comes from different choices of tools and different arrangements for production scheduling priorities.
When you did CNC four-axis machining last time, what was the gap between the actual quotation and your expectation? I hope to talk about this topic in the comment area. If you think the content is of practical value, you might as well give yourself a like and share it with your peers.
