What is the CNC machining cost per hour for 3-axis, 5-axis and lathe work?
CNC machining cost per hour is the shop rate a machine shop charges for one hour of a machine working on your part, with the operator, programming support, tool wear, floor space and plant overhead folded into that one figure. Because it is the shop’s own costs divided by the hours it expects to bill, it climbs with machine capability: a 2-axis CNC lathe or a 3-axis vertical mill sits at the bottom of a shop’s rate card, 4-axis mills sit in the middle, Swiss-type lathes in the middle to upper range, and 5-axis machining centers and mill-turn machines sit at the top.

This guide is written for the engineer or buyer who has a CNC quote in hand and wants to know whether the machine time behind it is reasonable. It explains what goes into an hourly rate, how the rate changes from a lathe to a 3-axis mill to a 5-axis or mill-turn machine, how labor costs differ between the United States, China and Vietnam, and why the hourly rate on its own is a weak way to compare two quotes. It deliberately does not publish a price list. Commercial shops rarely post their rates, so the figures cited below are ones that can be traced to a primary source: university shops that publish their charge-out rates, and government wage statistics.

What is a typical CNC machining cost per hour?
There is no official market rate, but two US university shops that publish their outside-work rates give a reference point: $116 an hour at the UC Riverside machine shop (its external commercial rate) and $155 an hour at Harvard’s design and fabrication service center (its external client rate). A commercial shop prices each machine above or below its blended rate according to what that machine cost and how much skill it takes to run.
Both are single hourly rates rather than a rate per machine, and Harvard states that materials are billed on top. The UC Riverside page lists $55 an hour for UC campus users and $82 for other academic clients alongside the $116 commercial rate, which shows how much of any rate is overhead allocation rather than the cost of the spindle itself. Commercial job shops usually keep a rate card per machine class instead, because a shop that charged the same rate for a depreciated manual-load lathe and a new 5-axis machining center would be overpricing one and losing money on the other.
The floor under every rate is labor. In its May 2025 national occupational wage estimates, the US Bureau of Labor Statistics reports a median wage of $24.37 an hour for computer numerically controlled tool operators, $28.24 for machinists and $32.75 for CNC tool programmers. A shop rate is typically several times the operator’s wage because the same hour also has to pay for benefits and payroll taxes, which the BLS tracks separately in its Employer Costs for Employee Compensation series, plus the machine, the building, quality control, programming, sales and profit.
How does the hourly rate change from a lathe to a 3-axis, 5-axis or mill-turn machine?
The rate rises with the machine’s purchase price, its tooling and workholding, and the skill needed to program and set it up. A 2-axis lathe and a 3-axis mill carry the lowest rates; 4-axis mills sit in the middle and Swiss-type lathes a little above them; 5-axis machining centers and mill-turn machines carry the highest.
The table ranks the common machine classes by where they usually fall on a shop’s rate card, and shows when the more expensive machine still produces the cheaper part. Use the last column as a line to add to an RFQ when the machine choice matters to you.
| Machine class | Position on the rate card | What pushes the rate up | When it still makes the cheaper part | What to state in the RFQ |
|---|---|---|---|---|
| 2-axis CNC lathe (turning center) | Lowest | Bar feeder, sub-spindle, live tooling if fitted | Round parts whose features are all on the turning axis | Bar size and material, and whether any off-axis holes or flats exist |
| 3-axis vertical machining center | Low | Table size, spindle speed, probing | Prismatic parts with features on one or two faces | Which faces carry tight features, so setups can be counted |
| 4-axis mill (rotary table) or horizontal machining center | Middle | Rotary axis, pallet changer, tombstone fixtures | Parts with features around a common axis, or batch work that fills a pallet | Realistic batch size, since pallet fixtures pay off over volume |
| Swiss-type sliding-headstock lathe | Middle to high | Guide bushing, many tool stations, longer setup and programming | Long, slender or small-diameter turned parts made complete in one cycle | Length-to-diameter ratio and annual quantity |
| 5-axis machining center | High | Machine price, CAM and collision checking, programmer skill | Parts that would need three or more setups and custom fixtures on a 3-axis machine | Datum scheme and which features must relate to each other across faces |
| Mill-turn (multitasking) machine | Highest | Machine price, two spindles, B-axis milling head, complex programs | Turned parts with milled or cross-drilled features that would otherwise move between a lathe and a mill | Feature relationships between turned and milled features, and run quantity |
What is included in a CNC shop hourly rate?
A shop rate bundles machine ownership (depreciation and financing), maintenance, power and floor space, the operator’s wage and benefits, a share of indirect costs such as programming, quality and management, and profit. Material, outside processing such as plating, and special tooling or fixtures are normally priced separately.
US government contract accounting gives a useful way to think about how those costs reach an hour of machine time. The Cost Accounting Standard on allocating indirect costs, 48 CFR 9904.418-50, states that a machine-hour base is appropriate when a cost pool is made up predominantly of facility-related costs such as depreciation, maintenance and utilities, and otherwise directs a direct labor-hour or direct labor-cost base, whichever better tracks the pooled costs. A commercial shop is not bound by that standard, but most rate cards follow the same logic: the expensive machine carries its own ownership cost, while the operator, programmer and inspector are spread across the hours they support.
Some shops make the split visible. Western University’s machine services rate page, for example, lists an hourly equipment charge for each CNC machining center and lathe, published separately from its labor rate schedules. Most commercial quotes fold both into one rate, which is why two shops with the same machines can quote different hourly figures: one may be running an older, fully depreciated machine with an operator tending two spindles, the other a new machine with one operator per spindle.
The biggest single variable a shop cannot show on a quote is utilization. An hourly rate is annual cost divided by billable hours, so a machine that runs two shifts spreads its ownership cost over roughly twice the hours of one that runs a single shift. That is the main reason high-volume production shops can quote lower rates on the same machine model than prototype shops.
How do CNC machining rates in the US, China and Vietnam compare?
Rates in China and Vietnam are lower than US rates mainly because labor, buildings and overhead cost less there; an imported machine tool is bought on the international market wherever it is installed. The gap is therefore widest on labor-heavy work such as small batches, manual setups and hand deburring, and narrowest on capital-heavy 5-axis machine time.
The table lines up the government wage benchmarks that set the labor floor in each country, and the import charges a US buyer adds back before comparing prices. Minimum wages are legal floors, not what skilled CNC setters or programmers earn; they are listed because they are the official, comparable figures each government publishes.
| Benchmark | United States | Vietnam | China |
|---|---|---|---|
| Official labor figure | Median wage: CNC tool operators $24.37/h, machinists $28.24/h, CNC tool programmers $32.75/h (May 2025) | Region I statutory minimum VND 5,310,000 per month or VND 25,500 per hour (from January 1, 2026) | Shanghai statutory minimum CNY 2,740 per month (full-time) or CNY 25 per hour (part-time), from July 1, 2025 |
| What the figure is | Market median for the occupation | Legal floor for the highest-cost region; skilled machinists are paid above it | Legal floor for the highest-cost province; skilled machinists are paid above it |
| Machine tool cost | Set by the machine builder; imported models are bought on the international market | Imported models, plus import logistics and any duties on the machine | Imported models or machines from domestic builders |
| Charges a US importer adds | None (domestic purchase) | Duty under the HTSUS line, merchandise processing fee per 19 CFR 24.23, freight, and any Chapter 99 measures in force | As Vietnam, plus Section 301 duties on listed China-origin goods |
The sources behind the table are the BLS occupational wage estimates, Vietnam’s regional minimum wage published through a Can Tho city government legal portal summary of Decree 293/2025/ND-CP, and the Shanghai adjustment as reported by The Paper in 2025. Section 301 actions on China-origin goods are listed by the Office of the US Trade Representative; check the current HTSUS heading for your part before treating any offshore price as final.
Lower labor cost does not translate one for one into a lower part price. Machine depreciation, cutting tools, inspection equipment and material are bought at near-global prices, so a machined part that is mostly machine time and material shows a smaller gap between countries than one that is mostly handling. The Vietnam versus China machining guide covers the tariff side in more depth.
Why is the hourly rate a poor way to compare two CNC quotes?
Because part price is rate multiplied by time, and the time varies far more between shops than the rate does. A 5-axis machine at a higher rate that finishes a part in one setup can beat a 3-axis machine at a lower rate that needs three setups and three fixtures.
Consider a hypothetical prismatic part with features on five faces, using round numbers only to show the arithmetic. Shop A quotes it on a 3-axis mill at $85 an hour: three setups of 45 minutes each, and 18 minutes of cutting per part across the three operations. Shop B quotes it on a 5-axis machine at $150 an hour: one setup of 90 minutes, and 9 minutes of cutting per part because the part is never unclamped and re-indicated.
At a batch of 50, Shop A spends 2.7 minutes of setup per part plus 18 minutes of cutting, about 20.7 minutes, or $29.33 of machine time. Shop B spends 1.8 minutes of setup plus 9 minutes of cutting, about 10.8 minutes, or $27.00. At a batch of 10 the two are almost level, at $44.63 and $45.00, because Shop B’s long single setup is shared by fewer parts. The cheaper rate did not produce the cheaper part at volume, and the 5-axis route also removed two re-clamping steps where position errors between faces creep in.
The same comparison works the other way. A simple turned pin quoted on a mill-turn machine pays the highest rate on the card for features a plain 2-axis lathe makes just as well. When two quotes differ, compare the machine route and the time per part before the rate.
How do you calculate CNC machining cost from an hourly rate?
Divide each setup’s time by the batch quantity, add the cycle time per part, and multiply the total by the machine rate; then add material, special tooling or fixtures spread over the order, outside processing, inspection and margin. Done for every operation, that is the machining cost formula most shops use.
Cycle time is the part a buyer can estimate least well from a drawing. In a CAM system it is the toolpath length divided by the programmed feed rate, plus non-cutting time for tool changes, rapid moves, probing and part loading. Feed rate in turn comes from spindle speed, the number of cutting edges and the chip load the material allows, which is why a free-machining brass or aluminum part runs faster than the same shape in stainless steel or titanium at the same hourly rate.
Setup time includes loading the program, setting tool offsets, mounting or building the fixture and cutting and measuring the first good part. It is close to fixed per batch, so it dominates small orders. The CNC machining cost drivers guide lists the drawing decisions that shorten both setup and cycle time; the formula above only shows where they land.
How can a buyer sanity-check a CNC quote without knowing the shop’s rate?
Ask the shop to state the machine type, the number of setups, the setup time and the cycle time per part, then multiply back. If the implied rate or the implied time is far from what the part geometry suggests, ask which features drive it.
A breakdown turns one opaque number into a few checkable ones. A long cycle time on a part with modest stock removal often points to a small internal radius, a deep narrow pocket, a thin wall or a tight finish call-out that is forcing light passes. Many setups on a part a 5-axis machine could reach in one point to a route choice worth questioning. A large setup charge on a repeat order points to a fixture or program that is being rebuilt instead of reused.
When we review a drawing for CNC milling or CNC turning, we report the route, the setups and the features that drive cycle time alongside the price, so a buyer can see why the number is what it is and which drawing changes would move it. To get the most comparable quotes, send every shop the same package: a STEP model, a dimensioned PDF with tolerances and finishes, the material, the batch size and the annual quantity. The machining RFQ guide lists the rest, and our quote form accepts the files directly.
Frequently asked
Why do most CNC shops quote per part instead of per hour?
Because the buyer cares about the delivered part, and the shop carries the risk on how long it actually takes. An hourly quote is common for prototype, repair and engineering-support work where the scope is not fixed; production work is usually quoted per piece at a stated quantity.
Is the shop rate the same as what the machinist earns?
No. The machinist’s wage is only one part of the rate. The same hour also pays for benefits and payroll taxes, the machine’s depreciation and maintenance, power and floor space, programming, inspection, management and profit, which is why a shop rate is typically several times the operator’s hourly wage.
Do shops charge separately for programming and setup?
Some list them as a one-time charge on the first order; others spread them over the quoted quantity inside the unit price. Either way the cost exists. Ask the shop to show it separately so that a repeat order, which should not need the same programming effort, is priced accordingly.
Does a lower hourly rate in Vietnam or China mean a lower landed price?
Not automatically. Freight, duty under the HTSUS classification, the merchandise processing fee and any additional tariff measures sit on top of the ex-works price. The landed cost guide shows how to add them up before comparing with a domestic quote.
Is a 5-axis machine worth its higher hourly rate?
For parts with features on several faces that must relate to each other, often yes: fewer setups mean less setup time, fewer fixtures and fewer chances to lose position between faces. For simple parts machinable from one or two sides, a 3-axis machine at a lower rate usually makes the cheaper part.
