Understanding Your CNC Machining Quote
As a buyer of machined components, cost is always on your mind. Answering the question "How much does CNC machining cost?" is like asking "How long is a piece of string?" – it depends on several factors that influence the final price of your project.
One of the main factors is the quantity of parts you need. Larger orders usually mean a better cost per part, but more parts also mean a higher total cost. But what exactly are you paying for when you contract a CNC machining company?
In this article, I'll break down what a CNC machining quote should include so you can compare quotes from UK suppliers more effectively.
What Makes Up the Cost of CNC Machined Parts?
There are many factors that determine the price of your CNC machined components.
Some companies take a casual approach to quoting. They might receive your RFQ, glance at it, and give an estimate based on a guess. This method can be risky, as the company might later ask for more money once the part is in production.
A reliable machining company, however, will take the time to fully understand your part, get material quotes, plan the machining process, and set inspection requirements before providing a detailed and accurate quote.
So, what exactly goes into the cost of a CNC machined part? Let’s explore.
Raw Materials
This is the material the CNC machining company will likely purchase from a preferred supplier.
Some companies work closely with multiple suppliers and may even request multiple quotes to ensure they offer the best value for your project.
If a cheaper alternative is available, the supplier should reach out to you before proceeding with the quote.
Programming, Setup, and Machining Time
This shouldn’t be a quick guess. Many companies use experienced engineers to estimate the machining time accurately. This helps determine how long it will take to produce your part.
CNC machining companies often have a standard hourly rate that includes labor and machine operation costs. This rate typically makes up a large portion of the quote.
In the UK, most companies charge between £30 and £100 per hour. Expedited orders may come with a premium.
Complexity (Special Tooling)
Some complex parts may require non-standard tooling, which will be included in the cost. These tools are usually purchased specifically for the job.
Inspection Requirements
The level of inspection required can vary depending on the industry and application. More rigorous inspections may require additional time and equipment, increasing the overall cost.
First Article Inspection Reports (FAIRs) or other certifications can add extra time and cost, so it's important to clarify these details upfront.
Finishing Processes and Assembly
You might need your parts to go through finishing processes like anodizing or powder coating, or even assembly. It's worth checking if your supplier offers a one-stop solution for all these services.
This can save you time and reduce stress by dealing with a single supplier for all your needs, including plating, coatings, and small assemblies.
Shipping
While shipping costs may not always be itemized, they are still a factor. At Penta, our packaging and delivery fee starts at £26 per delivery.
Comparing Like-for-Like?
Most CNC machining companies don’t break down the costs in detail on their quotes. If it’s unclear what’s included, ask!
It’s crucial to know what each quote covers to ensure you’re comparing apples to apples. Communication is key.
Remember, if a quote seems too good to be true, it probably is. A very low quote might mean the company hasn’t considered all the costs, such as proper inspection or necessary tooling.
Working within a budget is important, but you don’t want to end up with unexpected charges later.
Conclusion
While I can't give you an exact price for CNC machining, understanding a quote empowers you to make informed decisions for your project. Hopefully, this article has helped you compare quotes confidently.
Remember, the cheapest quote isn’t always the best. Look for a supplier who takes the time to understand your needs, provides an accurate cost estimate, and communicates clearly throughout the process.
Prioritizing quality and clear communication alongside price ensures a smooth buying experience and avoids hidden costs in the future.
