When we talk about modern manufacturing, machining is an integral part. Whether it’s cars, airplanes, rockets, smartphones, or computers, machining is integral to their manufacturing process. So what exactly is machining? And how is it applied? Next, we will be from the principle to the application, all-round analysis of what is machining.
First, machining introduction
Machining refers to the removal of excess material from the surface of the workpiece to change the shape, size and surface quality of the process. This process usually requires the use of machine tools, cutting tools, fixtures and other equipment and tools, as well as the corresponding materials.
Second, the principle of machining
The principle of machining is simple: the excess material is removed by the relative motion between the tool and the workpiece. This process usually includes turning, milling, grinding and several other basic machining methods.
- Turning: Turning is a machining method in which the workpiece is rotated and the tool is moved along the axis of the workpiece to remove excess material. This method is mainly used for machining shaft parts.
- Milling: milling refers to the tool rotation, workpiece movement, in order to remove excess material processing methods. This method is mainly used for machining flat and complex shaped parts.
- Grinding: Grinding is a machining method that uses abrasives to cut the surface of the workpiece. This method is mainly used to improve the surface quality and accuracy of the workpiece.
Third, the application of machining
Machining has a wide range of applications in the manufacturing industry, involving almost all industrial fields. Here we look at machining in several major areas of application.
- Mechanical manufacturing: mechanical manufacturing is the main application areas of machining. In the field of mechanical manufacturing, machining is used to manufacture various parts or complete machines.
- Construction industry: In the construction industry, machining is mainly used to manufacture and process construction materials, such as steel bars, cement, and so on.
- Automotive industry: In the automotive industry, machining is used to manufacture various parts and components, such as engines, gearboxes, bearings, and so on.
- Aerospace industry: In the aerospace industry, machining is used to manufacture a variety of high-precision, high-performance parts, such as engine blades, wing wing beams and so on.
- Electronics industry: in the electronics industry, machining is mainly used to manufacture a variety of precision parts and components, such as cell phone parts, computer parts and so on.
Fourth, the advantages and disadvantages of machining
Machining has many advantages and some disadvantages. Here we will look at what are the advantages and disadvantages of machining.
Advantages:
- High machining precision: machining can achieve high machining precision, and can meet the needs of a variety of high-precision parts.
- High processing efficiency: machining has high processing efficiency and can realize mass production.
- Wide range of processing: machining can process a variety of materials and shapes of parts, has a strong adaptability.
- Low production cost: the production cost of machining is relatively low, and can meet the production needs of various price requirements.
Disadvantages:
- The machining process generates cutting forces and cutting heat, which may cause breakage to the workpiece and tool.
- The machining process generates a lot of chips and noise, which has an impact on the environment.
- The investment and maintenance costs of machine tools and cutting tools are high, which is not economical for some small batch production or production of single parts.
Summary
Machining is an indispensable part of modern manufacturing industry, which is widely used in various fields with its high precision, high efficiency, low cost and other advantages. With the continuous development of science and technology, machining will continue to innovate and develop, bringing more convenience and beauty to our lives.
