When picking a material for CNC milling, you need to know your design’s needs, the part’s job, and your budget. Think about strength, machinability, cost, and how the part will be used. Then match those needs to what each metal or plastic can do. Good material choices save you time, money, and trouble.
Thread tapping is cutting threads inside a hole using a tap. The tap has cutting edges shaped to match the thread profile. As it turns into a drilled hole, it removes grooves to form a threaded path.
Spring steel stamping is a process that uses a press and a matched die set to cut and shape thin sheets or strips of spring steel. The die applies controlled pressure and movement to form the material. This process can perform several operations, including blanking, piercing, bending, coining, embossing, and drawing.
Blow molding is a plastic-forming method. It starts with melting plastic and forming it into a hollow tube called a parison. This parison is then placed in a mold. Compressed air is then blown into the parison. The air pushes the plastic outward, and it takes the shape of the mold. Once cooled, the mold opens, and the part is removed.
Taper turning is the process of cutting a surface that gradually changes in diameter along the length of a round workpiece. It forms a cone-like shape using a lathe. The taper can be on the outside (external) or inside (internal) of the part. The angle and length of the taper are based on what the part is used for.
Circular runout controls variation at each circular cross-section. Total runout controls the entire surface across the length. Circular runout focuses on roundness at one spot. Total runout adds straightness and taper checks across the whole feature.
Sheet metal drawings are technical documents that show a part’s size, shape, and key features. They often list material type, thickness, and finish requirements. Depending on the project, these drawings can be in 2D or 3D. They provide precise cutting, bending, welding, and finishing instructions.
Laser cutting parameters are the adjustable settings on a laser machine. These include laser power, cutting speed, focus position, assist gas type, gas pressure, and nozzle distance. Each affects how the laser melts, burns, or vaporizes the material. The correct settings depend on the material type, thickness, and the desired edge quality.
Laser welding aluminum melts and joins aluminum pieces with a focused laser beam. The heat is concentrated in a small area, creating a narrow, deep weld. Shielding gas, often argon or helium, protects the molten metal from air contamination. This process works well for both thin sheets and thicker sections, giving consistent and repeatable results.
Laser welding uses a focused light beam to melt and join metal surfaces. The beam applies heat to a small, controlled area, creating deep, narrow welds and limiting heat from spreading to nearby material. It is beneficial for thin sections, delicate parts, and complex shapes.
Laser welding uses a focused beam of light to melt and join metal. TIG welding uses a tungsten electrode and gas to form a weld. Laser welding is fast, clean, and suitable for automation. TIG welding is slow but precise and flexible. The best choice depends on the type of job, material, and the need for speed versus control.
Composite CNC machining uses advanced equipment to cut and shape tough materials like carbon fiber and fiberglass. Specialized tools and methods reduce tool wear and keep parts strong. This process lets you make lightweight parts for industries like aerospace, automotive, and medical.
A 5-axis lathe is a CNC machine that rotates and moves the cutting tool along five axes. These include the usual X, Y, and Z linear axes, plus two rotary axes, often labeled as A and B or B and C. This setup allows the tool to approach the part from almost any angle.
Design for Manufacturing (DFM) means designing products that are easy and cost-effective to make. The goal is to reduce costs, speed up production, and avoid problems later. DFM looks at every detail of a design and checks if it fits the tools, machines, and materials used in the factory.
Laser Beam Machining (LBM) is a non-contact process that uses a focused beam of light to remove material. The laser heats a small area of the workpiece. The material melts or vaporizes. The beam can cut, drill, or engrave depending on the settings.
Heat-treated steel is steel that has been heated and cooled in a specific way to change its internal structure. It works by changing the microstructure of steel, which is made up of grains that form during solidification and cooling. The goal is to control how these grains form and change.
