You get fast service and good quality. This helps you finish your projects on time. When you pick a trusted cnc milling parts factory, you know your metal materials and alloys will come on time and be just what you need.
Picking the right material is a big step in CNC milling. You want your parts to work well and last a long time. You also want to stay within your budget. The material you pick changes how your parts work, how much they cost, and how easy they are to make. You need to think about strength, how easy it is to machine, price, and what your parts will do.
Start by looking at mechanical properties. These tell you how a material acts when used for cnc components or precision metal parts. If you want strong and tough parts, check these things:
| Mechanical Property | Description |
|---|---|
| Strength | Shows how much force a material can take before it bends or breaks. |
| Hardness | Tells how well a material can resist scratches or dents. |
| Ductility | Shows if a material can stretch without breaking. |
| Impact Resistance | Tells if a material can handle hard hits without breaking. |
Match the mechanical properties to what your parts need to do. If your parts need to hold heavy things, pick a strong material. If your parts might get dropped, pick one with good impact resistance. Hardness helps stop scratches and dents. Ductility lets parts bend instead of breaking.
Machinability is also important. If a material is easy to machine, you save time and money. Good machinability means you can make parts faster and better. If a material is hard to machine, you need special tools and more time. This can slow you down and cost more.
Good machinability helps you make parts faster and cheaper.
Bad machinability means you need special tools and more changes.
Machinability changes how good your finished parts are.
Think about how the material acts when you cut it. Machinability depends on how the material handles heat, how hard it is, and how it reacts to cutting.
The material you pick changes your budget and how fast you finish parts. Metals and plastics cost different amounts and take different times to machine. You need to balance price and how well the part works.
| Category | Metals | Plastics |
|---|---|---|
| Material Costs | Usually cost more per pound | Cheaper for testing, but some plastics cost more |
| Machining Times | Need strong tools and take longer | Can be cut faster but may waste more if not careful |
Compare the price and how well each material works. Metals like titanium or stainless steel cost more but are very strong. Aluminum and plastics are easier to machine and cost less. If you want to save money, pick a material that is easy to cut and does not wear out your tools.
| Material | Cost Range | Machining Difficulty | Tool Wear |
|---|---|---|---|
| Aluminum Alloy (6061) | ¥80-120/kg | Low | Lower |
| Stainless Steel (304) | ¥150-250/kg | Medium | Higher |
| Titanium Alloy (Ti6Al4V) | ¥800-1,200/kg | High | Needs special tools |
Check how the material acts when you machine it. Look for problems like tool wear, speed, and accuracy. If you pick the wrong material, you might get rough parts or parts that do not fit. This can cost more and mean you need to change tools more often.
Tip: Always balance price and how well the part works. Do not pick the strongest material if you do not need it. You can save money and still get good parts.
Think about the environment too. If you want to be eco-friendly, pick materials like aluminum or steel that can be recycled. CNC machining helps you use less material and make less waste.
The material you pick depends on what your parts will do. Think about where your parts will go, how they should look, and what rules they must follow.
| Requirement Type | Description |
|---|---|
| Environmental | Includes heat and cold resistance, flame safety, or UV and chemical protection. Some jobs need food or medical grade materials. |
| Electrical | Some parts need to carry electricity or stop static. Pick the right material for this. |
| Mechanical | Think about how strong, tough, or wear-resistant your parts need to be. |
| Cosmetic | Some parts need to look good or have a certain color or texture. |
| Size | Some materials only come in certain sizes. |
| Cost | Price is important and can change what you pick. |
Check if your parts need to handle heat, cold, or chemicals. Some materials can bend or break if the temperature changes a lot. If your parts will be near strong chemicals, pick a material that does not react. If you want your parts to look nice, pick a material with a good finish or color.
If you make cnc components for special jobs, you need to follow industry rules. Aerospace, car, and medical jobs have strict rules for materials. Pick materials that meet these rules so your parts work well and stay safe.
Note: Picking the wrong material can cause problems later. Your parts might wear out fast, break, or not work right. Always think about what your parts will do before you choose.
Think about the size of your parts too. Some materials only come in certain sizes. Make sure the material fits your design.
To avoid mistakes, keep your designs simple. Do not add tiny details that are hard to machine. Small letters, thin walls, or tiny holes can make machining harder and cost more. Make sure holes are the right size for threads.
You do not have to pick alone. CNC experts, like the team at Waltay, can help you choose the right material. They know how to match materials to your needs. You can ask them about how long it takes to get materials, if they are easy to find, and how to test your parts.
