We share information and tips we’ve learned from our experience in the CNC machining and sheet metal fabrication industry.
Learn the melting point of iron, how iron thermal behavior affects CNC machining, and what engineers should know about heat, tool wear, tolerances, coolant, and iron-based material selection. What Is the Melting Point of Iron? The melting point of iron is commonly listed as about 1,538°C, or 2,800°F. This number describes the temperature at which […]
The question “is nickel magnetic” looks simple, but it becomes more practical when a CNC machined part is involved. Nickel itself is a ferromagnetic metal at normal room temperature, so a pure nickel sample can respond to a magnet. However, a finished machined component is rarely just pure nickel. It may be steel, aluminum, brass, […]
440A and 440C stainless steel are often compared because both are hardenable martensitic stainless steels used when a CNC machined part needs wear resistance, moderate corrosion resistance, and stable precision features. The real difference is not only hardness. Engineers also compare carbon content, carbide level, cutting difficulty, heat treatment movement, surface finish, and final cost. […]
Learn what AMS 4027 aluminum alloy is, how 6061-T6 and 6061-T651 are used in CNC machining, and how their machinability compares with maraging steel for precision parts. What Is AMS 4027 Aluminum Alloy? AMS 4027 aluminum alloy is best understood as an aerospace material specification rather than a separate aluminum grade. In most purchasing and […]
AISI/SAE 1008 steel and ASTM A36 steel are both low-carbon steels, but engineers do not usually select them for exactly the same reason. 1008 is commonly associated with low carbon content, ductility, cold rolled sheet, simple forming, and light-duty CNC machined features. A36 is a structural carbon steel specification used for plate, bar, angles, channels, […]
Learn what a customized herb grinder is, why CNC machining is used, which materials and features matter, and how to control tooth geometry, threads, tolerances, deburring, and surface finishes for durable dried-herb grinding products. What Is a Customized Herb Grinder? A customized herb grinder is a compact mechanical product used to break dried culinary herbs, […]
Iron is often selected for machined parts because it offers useful strength, rigidity, damping behavior, and cost advantages in many industrial applications. However, the density of iron is not just a reference number in a material chart. It influences part weight, cutting load, fixturing, shipping cost, vibration, thermal behavior, and the way a CNC shop […]
2020 vs 4040 vs 8020 aluminum is a common search when designers choose a modular frame, fixture, machine stand, 3D printer structure, robotic base, or custom CNC machined aluminum extrusion part. The comparison is useful, but the terms must be understood correctly. 2020 and 4040 usually describe metric profile sizes, while 8020 often means an […]
Oxidize brass antiquing methods create a controlled aged surface on brass by darkening the outer copper-rich layer and, when needed, polishing high points back to a warm metallic highlight. For CNC machined brass parts, this finish is more than a decorative color. It affects how grooves, threads, engraving, edges, knurled areas, and flat machined faces […]
Brass parts are often selected for CNC machining because they cut cleanly, hold fine details, and provide a warm metallic appearance. However, a freshly machined brass surface can show tool marks, handling stains, burr traces, and directional cutting lines. Brass sandblasting is used when engineers need a more uniform matte texture without changing the part […]
Technische tekeningen zien er complex uit omdat ze aanzichten, afmetingen, aantekeningen, afkortingen en technische tekeningsymbolen combineren in één gestructureerd document. Elke markering vertelt ingenieurs, machinebouwers, CNC-programmeurs, inspecteurs en leveranciers hoe een onderdeel moet worden afgemeten, gevormd, afgewerkt, gecontroleerd of gemonteerd. Wanneer één symbool verkeerd wordt begrepen, kan dit leiden tot onjuiste gereedschappen, verkeerde toleranties, herbewerking, vertragingen, […]
When silicon is added to an aluminum alloy in an engineering project, it is not included by accident. The addition changes how the alloy behaves during casting, machining, wear, and service. This often leads to a practical question: is silicon a metal, a nonmetal, or something between the two? This article explains elements such as […]
