Basic methods of machining metal mechanical parts

In the production of mechanical parts, metal is the most common processing material. However, different metal processing materials, or different processing technology requirements, the processing methods used in the processing of mechanical parts are also different. Below we will introduce the metal processing methods commonly used in precision parts processing plants, so that everyone can have a certain understanding of this.

Parts Processing


There are many types of modern machine tools, innumerable models and sizes. Some small machine tools can be installed on the workbench, and some large machine tools need to be built in a special workshop to accommodate them. Simple machine tools are relatively easy to operate, while some machine tools are very complex in structure and operation. Whether the machine tool is large or small, simple or complex, there are only a few categories in total, and these categories correspond to the basic methods of forming metal.

Drilling is the process of drilling holes in solid metal by machine parts processing plants. Use a rotary drill called a twist drill. A drilling machine is a machine tool used for drilling. Drill presses also come in a variety of models and specifications. In addition to drilling, drilling machines can also perform other processing. When drilling, the workpiece is positioned, clamped and fixed; the drill bit rotates while drilling into the workpiece.

2.Turning and Boring

Ordinary machine tools are the most common machine tools used for turning workpieces, and are essential in the processing of mechanical parts. Turning is the process of removing metal from a workpiece in a precision mechanical parts factory. While the workpiece rotates, the tool cuts into or turns along the workpiece.

Boring is a processing method for expanding or further processing holes that have been drilled or cast in metal workpieces. Boring on a lathe is accomplished by a single-edged tool that feeds into the workpiece as it rotates.


Milling is the process of removing metal by a precision machine parts factory using a rotary tool with multiple cutting edges called a milling cutter. The machining of more complex precision parts requires milling, and only experienced precision parts processing masters can operate the milling process.
