How Much Does CNC Machining Cost Per Hour?

How much does CNC machining cost per hour?

For the same CNC processing business, some factories quote 35 yuan per hour, while some factories quote as high as 100 yuan per hour. The price gap between the two parties has almost quadrupled.

As for how much money it will ultimately cost, it mainly depends on what kind of parts the customer wants to produce. It also depends on the type of material used in the workpiece. At the same time, customers' specific requirements for processing accuracy are also one of the key factors that determine costs.

Processing difficulty directly determines the bottom line of price

CNC machining is not the end of cutting a square piece of material.

If the parts have multi-axis linkage, or have special-shaped curved surfaces and thin-walled structures, the difficulty level will rise significantly. For example, a factory in Dongguan that specializes in making mobile phone middle frames received an order for an ultra-thin titanium alloy middle frame in 2025. This order greatly extended the processing time of a single part from the conventional 40 minutes to nearly two hours, so its quotation naturally increased accordingly.

Compared with a simple three-axis milling operation and five-axis simultaneous machining, there is a significant difference in the complexity of the tool path . The difference between the two can be several times greater.

For the use of five-axis equipment to process a single part, the proportion of time spent in the programming stage usually accounts for more than 30% of the total production hours, and this increased cost will eventually be reasonably apportioned and reflected in the product quotation system within each hour.

Material costs widen the price gap

Aluminum, steel, titanium, copper. The price difference of materials is several times higher. In October 2025, the price of 6061 aluminum plate was approximately 21,000 per ton. 316 stainless steel plate costs more than 180,000 yuan. Calculate the blanks of the same size. The material cost of steel parts is seven to eight times that of aluminum parts. The material loss in the processing fee is naturally different.

Titanium alloys are more expensive, costing more than 400,000 yuan per ton. When cutting, the tool wears very quickly, and the amount of work that a tool can complete may only be a fraction of that of aluminum parts. When using titanium alloy to perform CNC machining operations, the cost of tools and time are rising, so the hourly quotation will naturally appear to be much higher.

Volume and precision are invisible levers

If the batch size is large, the unit price will become very low. There is a company in Shenzhen that specializes in 3C foundry. In 2025, it received an order for 200,000 aluminum shells from a certain brand.

The processing cost allocated to a single product is kept very low. Calculated into the specific value per hour, it is within the range of 35 yuan to 40 yuan. If the batch size is not large enough and only the prototype parts are used for trial production, it will take up half of the working time just to perform the clamping and debugging work.

The accuracy has increased from plus or minus 0.01 mm to plus or minus 0.01 mm. Upgrading of equipment, replacement of cutting tools and improvement of environmental conditions must all be completed simultaneously. Factories that produce medical devices and aerospace components usually use constant-temperature workshops and higher-level machine tool equipment. The costs related to these hardware will eventually be reflected in quotations of 60 to 80 or more per hour.

Equipment grade determines unit price per hour

How much does CNC processing cost per hour for an old three-axis vertical machining center and an imported equipment with automatic tool change function and high-speed spindle? , to complete the same task, the efficiency gap between them is several percent.

At this point in time in 2025, there is a factory in Suzhou that specializes in the production of hardware products. It uses an automatic loading and unloading system to process steel parts. As a result, its production cycle is shortened by nearly 30%. However, if the depreciation of the equipment and the costs related to operation and maintenance are calculated every hour, the final quotation level will reach a range of 80 yuan to 100 yuan.

The higher the degree of automation, the more expenses manufacturers will need to invest in the early stage. The cost of a complete automated production line can easily reach millions, and manufacturers need to allocate these related costs back to each order. In this way, the final quotation will naturally be pushed up.

Once a buyer sees that the price is very high, it does not necessarily mean that the manufacturer is deliberately trying to rip off customers. This may just be because the purchase cost of the large equipment itself is not low.

Don’t ignore labor hours and hidden costs

CNC machining is not all done by pressing a button. From programming, clamping, tool setting, to trial cutting, to first-piece inspection, and subsequent replacement of batches, the sum of the various processes before and after often accounts for about 40% of the total working hours. Many times, the quoted price only takes into account the actual cutting time, but when it is actually put into operation, you will find that the time spent on auxiliary work is the major factor.

If you encounter a situation where you need to work overtime to rush the work, or if you are producing during the night shift, or if you need to rush shipments to catch up with the holidays, then the labor hour fee will be directly adjusted upward. By the end of 2025, many factories will be accepting orders to deliver goods before Christmas. At this time, the processing fees for night shifts are usually 20 to 30 percent higher than those during normal times.

Manufacturers may not necessarily explain the calculation method of this additional cost very clearly in advance, so before placing an order and paying for the goods, it is best to ask clearly about the specific pricing method.

When choosing a merchant, don’t just focus on the unit price.

A lower quote does not necessarily mean it is a good deal. I have seen people go to a small-scale workshop in order to save a few dollars. As a result, the entire batch of goods had to be reworked because the dimensions were seriously out of tolerance, and the money spent was more than double the original savings.

In 2025, a customer who makes UAV racks found a company in Zhejiang and Guangdong for sample testing. The cheaper one has a tolerance of ±0.05, while the more expensive one has a tolerance of ±0.01.

A more reliable approach is to take the same drawing to two or three companies for price inquiry, carefully check the equipment list, inspection reports and past cases, and then comprehensively compare the price and delivery time. Regarding the quotation of CNC machining services, it is not the kind of CNC machining service quotation that is a one-time deal. For long-term cooperation, service response speed and quality stability are far more important than the ten or eight yuan difference between the unit prices.
