VMT 2026 05 23 Can you imagine this mess? Your carefully designed hydraulic manifold blocks are finally assembled on the production line. Suddenly, a tiny internal leak or external seepage occurs, causing the pressure of the entire system to fail. This leaves you scrambling to find a new, competent supplier—dragging down your project timeline, wasting valuable time, and draining your budget. This is exactly where pressure testing for CNC parts becomes absolutely critical.

VMT 2026 05 21 This blog will introduce the corrosion resistance degrees, typical applications for CNC machining, and the machining cost of these food-grade stainless steels. At the very end, we will also share a case study of how we suggested and processed the right stainless steel based on the parts’ use environments, surface finish, and budget requirements from our clients.

VMT 2026 05 20 Although both high carbon steel 1075 and 1095 can be called “spring steel,” they do not possess the same properties. Would you prefer the higher impact resistance of AISI 1075 steel, or the higher hardness and wear resistance of AISI 1095 steel? But it is not as simple as this impression; you should pay attention to their detailed differences in composition, mechanical properties, and machinability—which is closely related to machining cost—and applications. Understanding these can help you make a more economical or durable choice. At the very end, we will also share a case study of how we suggested to our clients the suitable one for their custom drive sprockets with performance and assembly requirements.

VMT 2026 05 19 If there’s a metal that not only provides excellent impact resistance and toughness but also outstanding wear resistance and durability—yeah, we say the 1075 high carbon spring steel. Would you like to use it for mechanical components that must withstand high loads and frequent impacts, and perform with an exceptionally long fatigue life? If you search for 1075 steel, the web will most likely lead you to springs or knives. However, it can also be used for precision CNC machining to make parts like transmission shafts, ratchets, sleeves, or liners—only when high impact toughness and high elasticity are required. Otherwise, alloy steels like 4140 or 4340 might be more popular choices.

VMT 2026 05 18 If you are now sourcing a custom precision shaft part, would you like the part to be more tough and wear-resistant, or to be more corrosion-resistant? D2 tool steel and 1095 high-carbon steel are apparently high-strength and high-hardness steels—you can take advantage of the higher toughness and impact resistance of 1095, and you can also use the “semi-stainless” steel D2’s better corrosion resistance due to its high chromium content.

VMT 2026 05 14 This free-machining alloy 2011 can provide good strength, hardness, and an excellent surface finish for mass CNC machining with short chips and less tool damage. Whether you are sourcing components for lightweight automotive sensors, electronics, or precision valve parts, you can trust the 2011 aluminum alloy in aspects of efficiency and tight tolerance. It seems aluminum 2011 is similar to the versatile aluminum 6061 from the introduction above, right? But it’s not. In this blog, we will also share a case study on how we solved the issue of achieving “strict dimensional tolerances without boosting production costs or extending delivery cycles” for one of our clients.
