CNC Milling Cost: Alles, was Sie wissen müssen
If you need custom parts made, CNC milling is one of the best options. But before starting, you might ask how much does CNC milling cost?
Let’s answer that question in this blog. So keep reading!
What is CNC Milling?
CNC milling is a process where a computer-controlled machine cuts material from a workpiece to create custom parts and shapes. The machine uses spinning cutters to shape the material based on a programmed design.
Unlike CNC lathe machining, which is better for making round parts, CNC-Fräsen is great for creating flat or angled features. CNC milling machines come in different types, from simple 3-axis machines to advanced 6-axis systems that can handle very complex tasks.
People sometimes say “CNC milling” when they mean “CNC machining”. But CNC machining includes other methods, like drilling, turning, and cutting with electricity (EDM).
Types of CNC Milling
Below are the types of CNC milling machines and how they work.
Vertical Milling
In a vertical milling machine, the cutting tool spins up and down (like a drill). These machines are popular because they are affordable, easy to program, and still very useful. A basic vertical CNC milling machine moves in three directions:
- The cutting tool moves up and down.
- The table moves forward and backward.
- The table also moves side to side.
Horizontal Milling
Horizontal milling machines work just like vertical ones, but the cutting tool spins sideways instead of up and down. They can use the same tools as vertical mills, but they are usually more expensive and better for making large numbers of parts.
Most horizontal CNC milling machines have a fourth axis, meaning the table can rotate. This allows the cutting tool to reach different sides of a part without needing to stop and reposition it manually.
Many of these machines also have a pallet changer, which lets you load new parts while the machine is still running. This saves time because the machine doesn’t have to stop for part changes.
Multi-Axis CNC Milling Machines
The more axes a milling machine has, the more directions it can move, so it will be more flexible and efficient. However, machines with more axes also need more advanced programming and setup.
A 3-axis machine is simple to set up and program. It is also more affordable and can make complex parts, but sometimes it needs multiple setups to complete a job. A 4-axis machine can do more than a 3-axis machine, but it is harder to set up and may require better software.
Machines with 4 or more axes are the best choice for making complex parts. However, they need advanced setup and programming. These machines are more efficient when working on difficult jobs.
How Much Does CNC Milling Cost?
The cost of CNC milling depends on several factors. On average, you can expect to pay between $50 and $200 per hour for CNC milling services. However, the price can change based on the material, design complexity, and production volume.
If you need a simple part with a basic design, the cost will be on the lower end. But if your part is complex or requires advanced machinery, the price will be higher.
For example, milling a simple bracket might cost between $50 and $100, while a complex aerospace part could range from $150 to $200 per hour for precise machining.
Also, CNC milling prices vary by location. In some places, like China, CNC milling services may be more affordable than in highly industrialized areas.
Key Factors that Affect CNC Milling Costs
Knowing what impacts CNC milling costs can help you plan better. Here are the key factors:
Type of Machine
More advanced machines cost more to use. A 5-axis CNC machine, which can handle complex designs, is more expensive than a simpler 3-axis machine.
Material Used
Harder materials like stainless steel and titanium take more effort to machine, so they make CNC milling more expensive. Softer materials like aluminum or plastic cost less.
Complexity of the Part
The more detailed and precise the part, the more time, effort, and resources it needs, increasing the cost. This includes the number of unique features and any manual finishing.
Number of Parts (Volume)
Larger orders usually have a lower cost per part because setup costs are spread out. Small orders may cost more per piece.
Labor Costs
The time and skill of engineers, programmers, and machine operators also add to the cost.
Supplier Choice
Different CNC machining suppliers have different pricing. A well-equipped supplier with skilled staff may offer better quality at a competitive price.
Standort
Where the machining takes place affects pricing. Areas with high labor costs usually have higher machining costs. Some businesses reduce costs by working with overseas manufacturers.
Industry Regulations
Industries like aerospace and medical have strict regulations, which can increase costs due to extra testing and documentation requirements.
Hidden Costs in CNC Milling
CNC milling is a great way to create precise and complex parts, but there can be hidden costs that can add up quickly. If you’re not careful, these extra expenses can affect your budget and profit margins.
Let’s take a closer look at some hidden costs in CNC milling and how you can manage them.
Setup and Preparation Costs
Before machining even begins, you need to set up the CNC machine. This includes programming, choosing the right tools, and testing the setup. Each of these steps takes time, and time is money.
If your project requires frequent setup changes, the cost can increase even more. To reduce setup costs, try to standardize your designs and use the same tools whenever possible.
Waste Material and Scrap Rates
CNC milling removes material from a solid block to create the final part. This means there will always be some waste. Mistakes, machine errors, or incorrect material choices can also lead to scrap parts. To minimize waste, double-check your designs before machining and use simulation software to test cuts before running the machine.
Shipping and Logistics Costs
Once your parts are ready, you need to get them to your customer. Shipping costs depend on the size, weight, and destination of the parts. If you need fast shipping, costs can rise even more. Planning ahead and working with reliable shipping partners can help you save money on logistics.
Potential for Rework or Design Changes
Sometimes, a finished part doesn’t meet the exact requirements. Maybe the design needs an update, or a small error occurred during machining. Fixing or remaking parts takes time and money. To avoid this, communicate clearly with your designers and customers before production starts. Also, test prototypes before making large batches.
Tips to Minimize CNC Milling Costs
CNC milling can get expensive—not just because of the machine itself, but also because of material and electricity costs. Here are some ways you can reduce expenses on your CNC projects:
Avoid Deep Cuts
Deep cuts require longer tools, which can lead to tool breakage, faster wear, and problems like tool deflection and overheating. This increases costs by requiring more tool replacements and slowing down production. Keep cuts shallower whenever possible.
Minimize Extra Finishing Steps
The more finishing work a part needs, the longer it stays on the machine, increasing costs. If possible, use the CNC-milled part as the final product instead of adding extra coatings, polishing, or treatments unless absolutely necessary.
Optimize Your Design
A well-planned design ensures efficient machining, reducing waste and cutting time. Poorly designed CAD files can lead to costly errors. Work with an experienced machinist early on to avoid unnecessary rework.
Keep Thread Lengths Short
Long threads don’t always add strength but do increase material and machining time. Use only the thread length needed for a strong connection.
Make More Parts at Once
The more parts you produce in one run, the lower the cost per part. Large production runs help spread out design and setup costs.
Choose Cheaper Materials
Material choice makes a big difference in cost. For example, stainless steel is much more expensive than plastic. If strength isn’t a major factor, switching to plastic like Delrin can save money.
Work with a Reliable Manufacturer
Not all CNC shops offer the same quality. The cheapest option may cut corners, leading to poor-quality parts and higher long-term costs. Find a manufacturer that balances quality with affordability.
Cost Comparison with Other Manufacturing Methods
Now, let’s compare the costs of CNC milling, CNC cutting, and CNC lathe.
CNC Milling vs CNC Cutting
CNC cutting slices through materials like metal, wood, or plastic using laser, plasma, or waterjet cutting—mainly for flat sheets. Costs range from $60 to $125 per hour, depending on the method and material
CNC milling removes material from a solid piece using a rotating tool, so it is ideal for detailed 3D shapes. Costs vary based on complexity, material, and precision, typically ranging from $75 to $200 per hour.
CNC Milling vs CNC Lathe
CNC lathe services are usually cheaper, costing $50 to $120 per hour, since they quickly produce round or symmetrical parts with minimal tool changes. CNC milling services, ranging from $75 to $200 per hour, are more expensive because they handle complex shapes, require more tool changes, and take longer to machine.
If you need simple, high-volume cylindrical parts, lathes are more cost-effective, while milling is better for detailed and intricate designs.
