A metal cutting machine is a machine that uses a cutting method to machine a metal blank into machine parts, which is customarily called a machine tool. Since the cutting process is still the main machining method for obtaining parts of a certain size, shape and precision in the mechanical manufacturing process, the machine tool is the most important component of the mechanical manufacturing system, which provides the relative position between the tool and the workpiece for the machining process. And relative motion, providing energy for changing the shape and quality of the workpiece.
Classification of machine tools
At present, there are many varieties and specifications of metal cutting machine tools. To facilitate the distinction, use and management, the machine tools need to be classified.
According to the national standard GB/T15375-94, according to the nature of processing and the different tools used, the machine tools can be divided into 12 categories: lathes, drilling machines, boring machines, grinding machines, gear processing machines, thread processing machines, milling machines, planer beds, broaching machines, Special processing machines, sawing machines and other machine tools.
In addition to the basic classification methods described above, there are other classification methods depending on other features of the machine tool.
According to the degree of machine versatility, it can be divided into three types: general machine tools (or universal machine tools), specialized machine tools and special machine tools. The universal machine tool is suitable for single-piece and small-volume production. It has a wide processing range and can process different processes of various parts. For example, ordinary lathes, horizontal boring machines, universal lifting table milling machines, etc.; specialized machine tools for mass production, narrow processing range, can process one (or several) specific types of one or several types of parts of different sizes Process. For example, precision screw lathes, crankshaft journal lathes, etc.; special machine tools are usually used in batch and mass production. These machines are specially designed and manufactured according to the process requirements, and are specially used to process one (or several) parts. Of a particular process. For example, a special grinding machine for machining a lathe guide rail, a special boring machine for processing a lathe headstock, and the like.
In the same machine tool, according to different processing precision, it can be divided into: ordinary precision grade, precision grade and high precision grade machine.
According to the quality and size of the machine, it can be divided into: instrument machine, medium (general) machine, large machine (quality up to 10t), heavy machine (more than 30t), super heavy machine (quality above 100t).
According to the degree of automation of the machine, it can be divided into: manual, motorized, semi-automatic and automatic machine tools.
In addition, the machine can be classified according to the number of main working organs, such as single-tool machine, multi-tool machine, single-axis machine, multi-axis machine.
At present, the machine tool is developing in the direction of numerical control, and its function is also increasing. In addition to the numerical control machining function, functions such as automatic tool change and automatic loading and unloading of workpieces are added. Therefore, it can also be divided into general CNC machine tools, machining centers, flexible manufacturing units, etc. according to the numerical control functions of the machine tools.
As new types of machine tools continue to emerge, the classification of machine tools will become more abundant.

An electric actuator is a device that converts electrical energy into mechanical motion. It is used to control the movement of various mechanical systems, such as valves, dampers, and other industrial equipment. Electric actuators are commonly used in industrial applications where precise positioning, speed control, and high accuracy are required. They are also used in the automotive industry, aerospace industry, and medical equipment. Electric actuators are available in different types, including linear actuators, rotary actuators, and multi-axis actuators. They can be powered by AC or DC power sources and can be controlled by various types of controllers, such as programmable logic controllers (PLCs) and human-machine interfaces (HMIs).
