How CNC Machining Works

The term CNC stands for 'computer numerical control', and the CNC machining definition is that it is a subtractive manufacturing process which typically employs computerized controls and machine tools to remove layers of material from a stock piece—known as the blank or workpiece—and produces a custom-designed part. This process is suitable for a wide range of materials, including metals, plastics, wood, glass, foam, and composites, and finds application in a variety of industries, such as large CNC machining and CNC machining aerospace parts. The automated nature of CNC machining enables the production of high precision and high accuracy, simple parts and the cost-effectiveness when fulfilling one-off and medium-volume production runs. Before the operator runs the CNC program, they must prepare the CNC machine for operation. These preparations include affixing the workpiece directly into the machine, onto machinery spindles, or into machine vices or similar devices, and attach

Short History of Screw Machines

Manufacturing truly is the backbone of America. Everything we have, use, and look at is a product of manufacturing. Often we thinking of that as the "putting together" of pieces of equipment, technology and such to create the product we see. But you have to stop and think, where did those pieces come from? Say you just bought a new desk and you need to assemble it. The screws and drawer rollers and other various metal and plastic parts contained in the kit come from somewhere and were made by someone. Now is when you start to realize that manufacturing actually has layers before the product gets to you!  Those metal and plastic parts are often made by a separate manufacturer through a process known as screw machining.  A screw machine comprises a hollow spindle and cams. A bar is fed into the machine, and the unwanted material is chipped away to create different types of screws, studs, and bolts. Automatic screw machines are types of metal working lathes, which are used to ma
