Brass is an alloy of copper and zinc, but the proportion of zinc varies to create different types. The most common types include alpha, beta, and alpha-beta brass. Depending on the application, each has distinct specifications, like corrosion resistance or machinability.
Broaching is a machining process that removes material from a workpiece using a special tool called a broach. The broach has a series of cutting edges, each slightly larger than the last, to remove material in steps. It is used for precision tasks, such as shaping, sizing, and creating detailed features.
CNC routing is a computer-driven cutting process. It uses a spinning bit to cut materials along a precise path. The machine reads a digital design file and then follows the programmed toolpath to shape the part.
This method works best for flat and 2.5D parts. It handles plastics, wood, aluminum, foam, and more. It’s used for signs, panels, enclosures, and prototypes. The machine can repeat the same job over and over with little variation.
Surface grinding is a machining process that creates smooth, flat surfaces on metal parts. It uses a rotating grinding wheel to remove material in small amounts. This method gives parts better dimensional accuracy and surface finish.
It is often used in toolmaking, diework, and precision manufacturing. Surface grinders vary in size and capability, so selecting the right one depends on part size, material type, and finish needs.
A metal fabrication shop is a workplace that shapes metal parts. It uses cutting, bending, welding, and assembly to turn sheet or structural metal into final products. Workers follow technical drawings and use tools like laser cutters, press brakes, and MIG welders.
Metal fabrication is a process for creating structures and parts from various metal materials. It involves cutting, bending, shaping, and assembling metals to form custom products. It covers various techniques used to make everything from car frames to electronic enclosures.
It helps create both custom prototypes and high-volume parts. Fabrication allows manufacturers to achieve accuracy, consistency, and cost savings across different projects.
Plain milling is a machining process in which a rotating cutter moves across a workpiece to remove material and create a flat surface. This operation is mostly done using horizontal milling machines, but vertical machines can also be used in some cases. The main goal of plain milling is to smooth the surface or cut grooves.
HPDC involves injecting molten metal into a metal mold under very high pressure. This pressure forces the molten metal into every part of the mold, resulting in highly detailed and precise components. Once the metal cools and solidifies, the part is ejected from the mold.
HPDC is most commonly used with aluminum, zinc, and magnesium alloys. Its speed makes it ideal for mass-producing parts with consistent quality.
Mechanical fastening refers to joining two or more components together using physical fasteners. Depending on the method used, these fasteners can create either permanent or non-permanent connections.
Mechanical fasteners are a practical and reliable way to create strong and secure joints.
The press riveting joining process fastens materials together by pressing rivets into holes. It involves placing a rivet in a pre-drilled hole and then applying pressure with a press machine. This causes the rivet to expand, creating a tight and permanent bond between the materials.
This method ensures a strong and durable bond without high heat or complex equipment. It’s commonly used in industries like automotive, aerospace, and electronics, where strength and precision are required.
Swiss machining is a type of CNC that produces small, high-precision parts. It supports the workpiece with a sliding headstock and guide bushing, reducing vibration and allowing for tighter tolerances.
Swiss machining gets its name from its origins in Swiss watch manufacturing. The process was created to make the tiny, precise watch parts.
In traditional lathes, the material is only held at one end, which can cause bending when cutting forces are applied. Swiss machines solve this problem by supporting the material at the cutting point.
Face milling is a machining technique where a multi-toothed cutter removes material from the surface of a workpiece. The cutting tool moves perpendicular to the workpiece, creating a flat and smooth surface in a single pass. Manufacturers use this method to make precise, clean surfaces with tight tolerances across various materials.
Zinc die casting is a process where molten zinc is injected into a steel mold under high pressure. The mold, also called a die, shapes the zinc into the desired part. Once the zinc cools and solidifies, the mold opens, and the part is ejected.
Zinc plays a critical role in die casting. It has a low melting point, which makes it easier to work with. This reduces energy consumption during the process. Zinc also has excellent fluidity, allowing it to fill intricate mold details.
Brass CNC machining is where computer-controlled machines shape brass into precise parts. It involves cutting, drilling, and milling brass based on digital designs. This method ensures high accuracy and consistency, making it ideal for custom components.
The key to machining carbon fiber is using sharp tools, high-speed spindles, and proper dust control. Specialized coatings reduce wear, while coolant-free machining prevents delamination. These steps improve accuracy and extend tool life.
A CNC shop has computer-controlled machines cutting, shaping, and finishing materials into parts. These shops handle everything from prototypes to large-scale production and are used in industries such as aerospace, automotive, and electronics.
CNC machine shops rely on skilled operators and engineers. They ensure the machines run smoothly and produce high-quality parts. Combining technology and expertise makes these shops a key part of manufacturing.
