High speed machining (HSM) is a cutting method that utilizes significantly faster speeds than standard machining. It involves higher spindle speeds, quicker feed rates, and rapid moves between cuts.
The primary goal is to remove material quickly without generating excessive heat. Fast and light cuts help keep the tools cool. This reduces tool wear and gives a smoother surface on the finished part.
Aluminum heat sinks are a solid option for most cooling tasks. They are lighter than copper and cost less. Copper heat sinks transfer heat better, but they are heavier and more expensive. If you’re looking for a balance of cost, weight, and performance, aluminum is usually the better pick. However, if you require top-level cooling in a confined space, copper is the best option.
Single point threading is a method that uses a cutting tool to create threads on a workpiece. It uses one tool shaped like the thread profile. As the part spins on a lathe, the tool moves along it and cuts the thread. This cutting happens slowly and in steps.
Aluminum is a silver-colored metal. It is soft, lightweight, and has good corrosion resistance. Pure aluminum is rarely used for parts. It’s too weak for most load-bearing tasks. But it’s excellent for electrical wiring and chemical equipment because it resists corrosion and conducts electricity well.
SFM means “Surface Feet per Minute.” It measures how fast the cutting edge of the tool moves across the material surface. This speed depends on how fast the tool spins and how big it is.
Think of it this way: if a cutting tool spins too slowly, the cut may not be clean. If it turns too fast, the tool may overheat or wear out quickly. SFM gives a number to help find the right speed.
Carbon steel machining needs clear steps, proper tool choices, and a focus on detail. Good planning helps you avoid issues like excessive tool wear or part distortion. Choosing the right cutting speeds, feeds, and coolants makes a big difference. Understanding the steel’s grade and condition lets you get the best results.
Low alloy steel is a type of steel that has small amounts of added elements, usually between 1% and 8%. These elements are added to improve the steel’s strength, hardness, resistance to rust, and toughness. Common added elements include chromium, nickel, molybdenum, and vanadium. These make the steel stronger and more durable than regular carbon steel but without the high cost of stainless steel.
DLC coating is short for Diamond-Like Carbon coating. It is a skinny layer of carbon-based material that shares some traits with natural diamonds. It’s a coating made from carbon atoms. These atoms are arranged in a way that mimics a diamond. This coating is applied to a part’s surface to make it harder, smoother, and more resistant to wear.
NEMA 1 and NEMA 12 are both types of industrial enclosures, but they serve different purposes. NEMA 1 protects against basic indoor dust and accidental contact. NEMA 12 offers better protection against dust, dirt, and dripping non-corrosive liquids. Your choice depends on where and how you plan to use the enclosure.
Infill refers to the internal structure within a 3D printed part. It supports the outer shell and gives the part its strength. Infill patterns, percentage, and orientation all affect how strong, heavy, or fast the part prints. Choosing the proper infill depends on your part’s use and requirements.
Both 6061-T6 and 6061-T651 offer high strength, good corrosion resistance, and excellent machinability. The main difference is stress relief. T651 is stretched after heat treatment, which reduces internal stresses. T6 is not. For most projects, either option can work, but T651 provides more stability when tight tolerances or large plates are required.
CNC tapping is an automated process that creates internal threads in holes using a computer-controlled machine. CNC tapping utilizes a specialized tool known as a tap. The tap spins and moves into the hole at the right speed. The machine follows a set program, so every thread has the same depth and pitch.
Fourslide metal stamping is a forming method that uses four moving slides to shape metal. These slides sit around a central point and move in from four sides. Each one holds a tool that bends or cuts the metal strip. Sometimes, a vertical press head is added to facilitate additional shaping.
Salt spray testing, also known as salt fog testing, is a method used for corrosion testing. It exposes metal parts to a fine mist of saltwater solution inside a controlled chamber. The goal is to create an accelerated corrosive environment. This test helps evaluate how coatings, platings, and surface treatments withstand harsh conditions.
Machining is a subtractive process. It removes material from a solid block, often metal, to create specific shapes. This is done using cutting tools, grinding wheels, or electric discharge. Most machining is performed on machines such as lathes, mills, drills, and grinders.
Metal embossing is a process that creates raised or recessed designs on metal sheets. It uses male and female dies to press the metal with force. This forms shapes like logos, textures, or warning signs without cutting or removing material. Embossing enhances both appearance and surface grip and can be used for decorative or functional purposes.
