CAD software is often used by designers and engineers to create the drawing of the part to be processed with CNC machining services, facilities your ideas go to reality. While the creation of 3D CAD models usually takes much time, so CAD libraries is very helpful, it can provides a diversity of ready-made free CAD files download for users. To improve the efficiency of finding free 3D models, here we list best 8 sites and libraries that you can get free models from. ......

Performance and properties are important references when selecting materials for an application, such as yield strength and tensile strength. The mechanical properties of aluminium alloys differ based on their temper, in this article, we’ll introduce the yield strength definition and compare it with tensile strength, please check the aluminum alloy yield strength chart to get the numerical values of the yield strength of aluminum. ......

Bronze and brass are two kinds of copper alloys used from ancient times, they have lots of similarities, but their composition and appearance are quite different. How to tell the difference between brass and bronze, here we are going to show the comparison between brass and bronze, make a proper choice when brass vs bronze. ......

When we speaking of strong metals, the first option we think about usually is steel or titanium. They both have a broad range of alloys with varying alloying elements and amounts, so it’s challenging to determine which type to start with. For deeper understanding of the difference between titanium and steel, we present some points and the titanium and steel comparison chart in the following content. ......

Steel is the structural material of the construction and transportation industry on the earth. Its alloy elements give it many excellent characteristics, and also derive a variety of types. Based on the designation system represented by AISI and SAE, we typically use a four-digit number to name different alloy steels. What we’ll outline in this post is 4130 alloy steel, from its detailed composition and fabrication characteristics, to 4130 steel properties and uses, as well as AISI 4130 steel vs 4140. ......

Holes can be machined on different types of machines through cutting away the unwanted materials, what machining operations need to be executed on a mill? There is a series of g-codes that indicates the movement of tools when cutting a hole on CNC milling machines. In this article, we’ll introduce the g-code for hole machining with the specific operations. ......

Stainless steel is a versatile material comes in multiple grades and alloys that differ in properties and characteristics. When manufacturing stainless steel machined parts for different industries, we need to learn about its feature and machining difficulties. In this article, let’s introduce what is 303 stainless steel, SS303 physical and mechanical properties, as well as the best grade of stainless steel for machining. ......

Aluminum is an important engineering material used in a vast range of industrial applications, it’s a relatively soft metal, which makes it can be cut with different tools. How to cut aluminum sheet metal with the easiest way? What’s the best tool for cutting aluminum? Follow us to learn about the best way to cut aluminum sheet and common tools to do it.   ......
