Manufacturing Process for Different Parts

Machining is a widely used manufacturing process, and it is also one of the common processing methods in the manufacturing industry for manufacturing various different types of parts. Different types of parts require different processes to process to meet their specific requirements. Many different part types and machining processes are included. The following are some common types of machined parts and the commonly used processing processes for each type: 

1. Plate parts: plate parts include various types of flat plates, thin plates, metal plates, chassis, brackets, etc. Plate parts are usually flat or curved. Machining processes include surface grinding, milling, shearing, bending, stamping, welding and riveting. Shearing is used to cut the plate into the desired shape, bending is used to bend the plate, stamping is used to create holes and concave or curved parts on the plate, and welding and riveting are used to join different plate parts together into a whole. 

2. Set of parts: sets of parts usually include bearings, sliding bearings, flanges, etc. These parts usually require machining processes such as internal turning, internal grinding, and cylindrical grinding to obtain accurate diameter and roundness. In addition, sets of parts may require drilling, reaming, tapping and other processing techniques. 

3. Block parts: Block parts include various types of squares, rectangular blocks, cylinders, etc. These parts often require machining processes such as plane grinding, milling, etc. to obtain precise flatness and profile. In addition, block parts may require drilling, tapping and other processing processes 

4. Casting parts: Casting parts are usually complex three-dimensional shapes, such as engine blocks, pump casings, etc. Processing processes include casting, grinding, turning and heat treatment. Casting is the primary method of manufacturing cast parts, which creates the shape of the part by pouring molten metal into a mold. Grinding, turning and heat treatment are then used to improve surface quality and precision. 

5. Electronic parts: Electronic parts are usually small, such as circuit boards, connectors, etc. Processing techniques include cutting, stamping, welding and plating. Cutting and stamping are used to make the shape and holes of circuit boards, soldering is used to connect electronic components, and electroplating is used to protect and improve surface properties. 

6. Plastic parts: Plastic parts are commonly used in various applications, such as injection molding, extrusion molding and compression molding. Injection molding manufactures parts by injecting molten plastic into a mold, extrusion molding works by extruding plastic into the desired shape, and compression molding heats the plastic and forms it in a mold. 

7. Bolts and nuts: Bolts and nuts are common components used to connect parts. They are usually round or cylindrical and need to be turned, cut and threaded. Turning is used to make the body shape of bolts and nuts, while cutting is used to cut threads. Threading typically includes single-point thread cutting and thread rolling. 

8. Gear parts: Gear parts include various types of gears, such as cylindrical gears, bevel gears, etc., which are usually round. The machining of gears usually includes milling, gear cutting, gear hobbing, shaving, shaving, grinding and heat treatment. Milling is used to make the basic shape of a gear, while gear cutting is used to cut the teeth of a gear. Grinding can be used to improve the precision and surface quality of gears. Heat treatment is usually used to enhance the hardness and wear resistance of gears

9. Shaft parts: Shaft parts are usually cylindrical and used for connection and rotation. Common shaft parts include bearing shafts, rotating shafts, drive shafts, etc. Machining processes include turning, grinding and threading. Turning is the most common method, by rotating the workpiece and removing the material with a tool to obtain the desired size and shape. Bearing shafts with high precision requirements can also be ground for grinding. In addition, shaft parts may require drilling, reaming, tapping and other machining processes. In addition to the above common types of machined parts, there are many other types of parts, such as special-shaped parts, freeform parts, etc. For each type of part, different machining processes can be used to achieve the accuracy and surface quality of the desired shape and size. For example, for complex special-shaped parts, CNC machine tools can be used for multi-axis simultaneous machining; For freeform surfaces, CMMs can be used for measurement and machining. 

In conclusion, different types of parts require different machining processes to meet their specific requirements. Choosing the appropriate process and machining method is critical to ensuring the quality, precision and performance of the part. In actual manufacturing, the appropriate processing technology is usually selected according to the shape, material and requirements of the part to achieve the best processing effect.
