I inspected the top two pieces of all five boxes. Everything is beautiful! BEAUTIFUL! You remove so much stress from my shoulders. I know that when we pay you to manufacture a product, it will be made perfectly. The glass bead blasting and anodizing is always beautiful. I am so very happy! You make it easier for us to run our business. There is no trouble! With most factories, I have a moment of fear before I open their boxes. Will the components be made correctly? Do they care about quality? It is often a war. And Dennis has to fight the war, treating most factories like small children! But, not your company. You’re company is world-class. You make beautiful components!Thank you very much for your hard work. We will work together for many lifetimes!
David, General manager for a family owned business
I’ve been working with Chinese manufacturers since 2004 and had some really unfortunate partnerships until 2012 when we partnered with Worthy Hardware. At first,we only gave them small orders to test and make the start. However,their response speed was very fast ,and their engineers help us improved our designs more simple, this helped us reduce a lot of cost.Our cooperate is more and more stable! We trust Worthy Hardware always ,very responsible. Your guys are great! .Worthy Hardware is by far my favorite, because of the way they handle business and the quality of what they make.If you are from USA and would like to know more about Worthy Hardware,i would be very happy to be as an endorsement.
CNC Machining Aluminum FAQs
1.which aluminum is the most popular used for CNC machining?
There are many types of aluminum for CNC machining filed, we find aluminum 6061 is the most popular used for CNC machining. Because 6061 is very cheap compared with aluminum 2024 or 7075, it is very easy to be CNC machined,CNC milled, CNC turned. It has a good strength-to-weight ratio, low cost, recyclability, non-magnetic, heat treatable, and natural corrosion resistance.
2.What are the surface finish for CNC machining aluminum parts ?
CNC machining aluminum parts could be anodized, alodine,sand-blasting, powder coating, painting, electroless nickle plating, brushed. This could made the aluminum parts with very good surface. Worthy Hardware could handle more than 30+ finish for the CNC parts.
3.How to avoid deformation in CNC aluminum machining?
CNC aluminum machining is widely used for many fields, however due to the large thermal expansion coefficient of aluminum alloy, it is easy to deform during thin-wall processing.During our past 25 years for CNC machining aluminum, we find that there are many many reasons for the deformation of aluminum alloy parts, which are related to the material, the shape of the parts, the production conditions, and the performance of the cutting fluid. Then there are 2 methods to avoid the deformation:
1) Reduce the internal stress of the blank part
2) Improve the cutting ability of the tool
4.What is the difference between 6061 and 6063?
| Different aspects | Aluminum 6061 | Aluminum 6063 |
|---|---|---|
| Different Anodize performance | 6063 anodize performance is better than 6061 | |
| Different content of alloying elements | 6061 has more alloying elements than 6063 | |
| Different plasticity | 6063 plasticity is better than 6061 | |
| Different alloying elements: | 6063 aluminum alloy is magnesium and silicon;6061 aluminum alloy is magnesium and silicon. | |
