Main Process for CNC Machining
Machining is when you take a piece of material and cut it into the shape, size, and properties you want using a bunch of different tools. You can use tools that spin (like turning, drilling, and milling), tools that go in a straight line (like planing and interpolating), or tools that grind. There are also a bunch of other ways to machine stuff, like using electricity (EDM) or a laser (laser machining). The type of machining you do depends on the material you’re cutting, how accurate you need to be, what the surface finish needs to be, and how many parts you’re making. Finally, you need to use the right speeds and feeds and how deep you cut to make sure you’re not wasting time, you’re making good parts, and you’re not wrecking the tool.
Preparation
- Tooling and fixture preparation: Choose the right tools, gauges and fixtures, and get all the other stuff you need to do the machining.
- Programming: For CNC machines, you have to write a program that tells the machine where to move, what tools to use, how fast to cut, etc.
Roughing
- Purpose: To get rid of a lot of material fast and get the basic shape of the part close to final.
- Use big tools and run them fast to get the most material off as quickly as possible.
- Focus on getting rid of extra material, not on getting the right dimensions or nice surface finish.
- Don’t worry about the little details or being perfect.
EQUIPMENT: Use whatever lathe, mill or CNC machine you have.
Intermediate Machining
- Purpose: Get closer to the final size and shape of the part and start focusing on more detailed features.
- Cutting parameters (cutting speed, feed rate, depth of cut, etc.) will be more conservative relative to roughing to improve machining accuracy.
- Begin to use specialized tools and fixtures to machine specific geometric features such as holes, slots, steps, etc.
- Specific strategies or processes may be used for parts that require special treatment such as thin-walled features or high-precision holes.
Equipment: Intermediate machining still uses lathes, mills or CNC machines, but with more stringent requirements for tool and parameter selection.
Finishing
- Purpose: To finally make the part the right size and the right shape and to finish the surfaces to the final condition required by the design.
- The last cuts are made with very sharp tools and the cutting conditions are carefully controlled to get the size right and the surfaces smooth.
- For parts that have to be really precise, grinding and polishing might be used after the machining is done.
- Every feature and every surface is measured and checked to make sure it meets the design requirements.
Equipment: In addition to lathes and mills, you might use grinders and other special machines to get the size right and make the surfaces smooth.
Inspection and Quality Control
- Size and Shape Inspection: Use tools like gauges, calipers, and CMMs to check if the size and shape of the parts meet the design requirements.
- Surface Quality Inspection: Check surface roughness and if there are any defects.
- Performance Testing: If necessary, conduct performance tests to make sure the part meets its functional requirements.

Estimated Cost Analysis For CNC Machining
Please note that the final cost depends on the customized service you require, the specifications of the raw materials used, the relevant national laws, and the distance of transportation. Take the example of booking a tall container of products:
This price includes the direct material costs，Machining time and labor, Complexity and precision, Overhead costs, Quantity and Economies of scale, Quality control and Certifications, and so on. Each one of those things is in the cost.
$98,000
Let’s take the United States as an example, there’s a bunch of things that affect the price, how far the stuff has to go, how much it costs to put gas in the boat, how much the boat can carry, and what’s going on in the world with shipping. The price goes up and down over time based on what’s happening in the world.
$4,300
Customs duties and taxes: When you import CNC Machining parts, the country you’re importing to might charge you customs duties and taxes. Insurance costs: Usually, you buy insurance for your goods to cover any risks that might happen during transit. Warehousing costs: You might have to pay to store your goods until they get to where they’re going. Logistics costs: You’ll also have to pay for logistics in the country you’re sending your goods to, like trucking fees, loading and unloading fees, etc.
$1,000The Process Flow & Duration Estimation
Please note that the time it takes to complete your custom product depends on the design complexity of your custom product, material availability, how you price your products, how many you make at once, how long it takes to do quality control, and external factors (i.e. a customer asks you to change something, etc.).
Step 1: R&D Drawings (3-7 days)
This stage involves the production of detailed engineering drawings, the selection of materials, and the definition of machining methods, and the designer needs to consider the functionality, durability, and aesthetics of the product. 3D modelling and simulation using modern engineering software (e.g. CAD and CAM systems) can anticipate potential structural or functional problems and optimise the design to reduce production costs. At the same time, close collaboration with the manufacturing team ensures the feasibility of the design and accelerates the product development cycle by reducing the need for late-stage adjustments through design reviews and revisions.
Step 2: Sampling (7-14 days)
The prototype phase is a big step in taking machined parts from an idea in your head to a real product that you can manufacture. It’s the phase where you get to see how your design actually works and make any necessary tweaks to it. During this phase, you’ll create prototypes or samples and conduct physical testing to make sure your design is functional, durable, and something people will buy. Physical testing may include load testing, durability testing, user experience testing, etc., to make sure your product does what it’s supposed to do when people use it.
Step 3: Pay The Bill (within 1 day)
The Parties will talk about good ways to pay, like how much to pay before starting, how much to pay while we’re working, and how to pay when we’re all done.
Step 4: Bulk Manufacturing (30-45 days)
To mass produce machined parts, you need to plan, get materials, get tools and machines ready, and figure out how to make the parts. To do it well, you need to make sure you have enough materials so you don’t run out and have to stop, and you need to make sure your machines are running right and cutting the parts the way they’re supposed to be cut. You also need to watch the parts as they’re being made to make sure they’re good. You need to check them when you start, check them while you’re making them, and check them when you’re done to make sure they’re good.
Step 5: Shipping (10-45 days)
The choice between sea, air, and land transport depends on the weight and volume of the goods, as well as the cost and time of delivery. Packing is also important. You need to choose the right packaging materials and methods based on the characteristics of your products (e.g. weight, shape, and material) to avoid damage during transport. Also, you need to work with your supplier to handle customs duties and import/export procedures to ensure that your goods can pass through customs smoothly.

The Basic Knowledge About CNC Machining
CNC machining is the backbone of modern manufacturing. It allows for complex machinery to be controlled with precision and automation.
CNC (Computer Numerical Control) machining is a process that uses computerized controls to run complex machinery like lathes, mills, and grinders. This technology allows for the automation of machine tools with high precision and repeatability, making it perfect for producing the same part over and over. By inputting the right information into a CNC machine’s computer, manufacturers can produce consistent, high-quality parts that are critical for industries like aerospace, automotive, and electronics.
The benefits of CNC machining include the ability to produce complex shapes that would be extremely difficult to achieve with manual machining. It is highly efficient because it reduces the time required to produce parts and minimizes material waste. Additionally, CNC machining can work with a wide variety of materials, from metals like aluminum and steel to plastics and composites, making it versatile across a wide range of manufacturing applications. By integrating CNC technology into production lines, you can achieve a high level of adaptability and scalability, whether you are producing small-batch custom parts or large production runs.
The Common Pitfalls When Purchasing
When you buy machined parts, you want to avoid some common mistakes to make sure the buying process goes smoothly and that you get parts that meet your quality and performance requirements. Here are some common mistakes and how to avoid them when you buy machined parts:
- Prices are too low
- Communication Problem
- Lack of technical ability
- Quality Issues
- Delivery issues
- No post-delivery support
Trap description: While low prices are obviously attractive to budgets, unusually low quotes can suggest poor quality materials, poor machining accuracy or suppliers cutting costs in other areas. In the long run, this can lead to higher repair and replacement costs and even damage to the company’s reputation.
Strategy: Conduct market research to determine average prices in the industry and consider the balance between purchasing costs and product quality. Ask suppliers to provide samples or pilot production first to verify their commitment to quality.
Pitfall: Misunderstanding technical requirements and specifications during communication, leading to a final product that doesn’t meet the requirements.
Prevention: Provide detailed technical documents and design drawings, and make sure the supplier understands the requirements. If necessary, have technical meetings or go to the supplier’s location for confirmation.
The problem: Suppliers may not have the technical know-how or equipment to make the specific machined parts you need, which means they’ll make parts that don’t meet technical specs.
The solution: Do a technical audit of the supplier, including evaluating their equipment, process flow, and technical team. For complex projects, you might consider co-developing with suppliers.
Pitfall: Your machined parts might suck because your supplier uses crappy materials, their machining isn’t accurate enough, or they don’t have good quality control processes.
Fix: Make your supplier give you quality certifications and testimonials from other customers. Do quality checks before the parts arrive, during production, and before they ship. If you have to, hire a third-party inspector.
Why it happens: The supplier might not be able to deliver on time because they don’t have enough capacity, they’re having trouble getting the raw materials, or they have internal issues.
What to do about it: Put the delivery date and penalties for late delivery in the contract. Stay in touch with the supplier to know what’s going on and consider having backup suppliers.
Some suppliers don’t provide any or very little support after they deliver your product. This can be a huge problem when something breaks or you need help with something technical.
Solution: Only work with suppliers who have good after-sales support and make sure it’s in the contract.
