There are many types of machining equipment:

1. The common J machines and equipment in the machining plant are (according to the processing method): turning-lathe, milling---milling machine, planing --- planer (plug---- inserting machine), drilling countersink (huò) reaming --- drilling machine, boring --- boring machine, broaching --- broaching machine, grinding--- grinding machine, polishing - polishing machine. The above types of equipment can be basically subdivided, lathes have general cars and several cars, planers have gantry planers, cattle head planers and slotting machines, drilling machines can be divided into table, vertical, rocker type, and so on.

The multi-functional integrated CNC machining center can complete a variety of processes such as drilling, boring, milling, countersinking, tapping and other processes at one time after the parts are clamped.

2. Sheet metal processing is also a major category of machinery, including punching machines (general punching, CNC punching), bending machines, laser cutting machines, plasma cutting machines and so on.

3. In addition to the above-mentioned turning, milling, drilling, boring and machining centers, there are also various grinding machines (coordinate grinding, smooth bending grinding, centerless grinding, small flat grinding, large flat grinding, internal and external cylindrical grinders), EDM (wire cutting) equipment, sawing machines, laser marking machines, etc.

4. The equipment for pre-processing and post-processing of machining also includes: heat treatment equipment, paint, electroplating equipment and so on.

5. Each industry has a focus, such as the automotive industry has four major processes: stamping, welding, painting, and **. In the workshop, punching machines, welding machines, and coating lines are necessary. Depending on the development, it is usually equipped with a larger or smaller mold workshop.

ps: If you operate the machine in the future, it is generally required to know more about CNC machine tools, especially machining centers, and accumulate enough experience to go up the career channel. If you are going to engage in mechanical R & D and design in the future, it is best to be able to contact these equipment in the field during the study stage, for even after graduating from university, if you want to lay a solid foundation for machinery, it is very necessary to rotate internships in various workshops, because whether you are engaged in mechanical technology or design and development, you should have a deep understanding of mechanical equipment processing capabilities, and you need to accumulate some knowledge and experience that you can't learn from books.

Remember, the machinery industry is made with both hands.

The place with the most machining in China is Suzhou City, Jiangsu Province. Suzhou is one of the famous machinery industry bases of Zhongmin Zhengguo, with many machinery enterprises and high-level machining technical personnel. The development process of Suzhou machining industry can be traced back to the 50s of the 20th century, after years of development, Suzhou machining has become an important part of China's machining industry.

Suzhou's machining industry has a number of advantages. First of all, Suzhou, as an important economic center city in southern China, has superior human resources and many mechanical and technical talents, which provides support for the machining industry. Secondly, Suzhou has a superior geographical location and convenient transportation, and is a logistics center, which provides convenience for the development of the machining industry.

At the same time, Suzhou has advanced mechanical equipment and exquisite machining technology, which also promotes the development of Suzhou's machining industry.

In addition to Suzhou, other parts of China also have a relatively developed machining industry. For example, Foshan City in Guangdong Province and Ningbo City in Zhejiang Province also have relatively developed mechanical processing industries. These regions have advantages in technology, talents, and enterprise scale in the machining industry, and have also made important contributions to the development of China's machining industry.

Overall, Suzhou City, Jiangsu Province, is one of the most machined places in China. There are many mechanical enterprises and high-level machining technical personnel, and the machining industry has a number of advantages. The development of Suzhou's machining industry not only provides good support for China's machining industry, but also makes important contributions to the world's machining industry.

The machinery for bamboo processing includes bamboo sawing machine, bamboo breaking machine, wire drawing machine, polishing machine, etc.

Wire drawing machine is also known as wire drawing machine, drawing machine, English name is drawingmachine, is widely used in industrial mold carrying machinery and equipment, widely used in machinery manufacturing, hardware processing, petrochemical, plastics, bamboo and wood products, wire and cable and other industries.

Polishers, also known as grinders, are often used for mechanical grinding, polishing, and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed, and the denafon polishing disc and the polishing agent work together and rub against the surface to be thrown, so as to achieve the purpose of removing paint pollution, oxide layer and shallow marks.

The rotational speed of the polishing disc is generally 1500-3000

r min, mostly continuously variable speed, can be adjusted at any time during construction.

There are too many machining equipment, and there is processing equipment for each part of each part.

For example, fasteners have thread rolling machines, tapping machines and so on.

For example, there will be planers, lathes or guesses, milling machines, drilling machines, grinding machines, punching machines and so on.

For example, gears have gear milling machines, etc.

Machining includes: filament power winding, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging, water jet cutting, precision welding.

Machining refers to the process of changing the dimensions or properties of a workpiece through a mechanical device. According to the difference in processing methods, hot processing and cold processing can be divided into cutting processing and pressure processing. Heat processing is commonly found in heat treatment, calcining, casting and welding.

With the rapid development of modern machining.

With the rapid development of machining technology, many advanced machining technologies and methods have slowly emerged, such as micro-machining technology, rapid prototyping technology, and precision ultra-precision machining technology.

Mechanical parts are composed of a number of surfaces, and to study the relative relationship between the surfaces of parts, a datum must be determined, and the datum is the point, line, and surface on which the position of other points, lines, and surfaces is determined on the part. According to the different functions of the datum, the datum can be divided into two categories: design datum and process datum.

Design datum: The datum used to determine the position of other points, lines, and surfaces on the part drawing is called the design datum.

Process datum: The datum used in the machining and assembly process of the part, known as the process datum. Process datums are divided into assembly datums, measurement datums and positioning datums according to different uses.

1) Assembly datum: The datum used to determine the position of the part in the component or product during assembly is called the assembly datum.

2) Measurement datum: The datum used to check the size and position of the machined surface is called the measuring datum.

3) Positioning datum: The datum used for workpiece positioning during processing is called positioning datum. The surface (or line, point) used as the positioning datum, only the unprocessed blank surface can be selected in the first process, and this positioning surface is called the coarse datum.

In the subsequent processes, the machined surface can be used as the positioning datum, and this positioning surface is called the precision datum.
