What are the traditional machining methods

1. Machining refers to the process of changing the overall size or performance of a workpiece through mechanical devices. According to the different processing methods, it can be divided into cutting processing and pressure processing.





2. The traditional processing methods mainly include:





Automobiles, pliers, milling, planing, cutting, grinding, drilling, boring, punching, sawing, etc. It also includes electroplating, wire cutting, casting, forging, electro-etching, powder processing, etc.





1. Body processing: (vertical car, sleeper): The main feature is the processing of the revolving body;





2. Milling: (end milling and horizontal milling): The main feature is the groove and straight line of the machined surface. Of course, the curved surface can also be machined into two-axis or three-axis linkage.











3. Planing: The main feature is the straight surface of the processed contour, and the surface roughness is generally lower than that of a milling machine;





4. Blade: It can be understood as a vertical plane, which is very suitable for incomplete arc machining.





5. Grinding: (surface grinding, cylindrical grinding, inner hole grinding, tool grinding, etc.) high-precision surface treatment;





6. Drilling: hole processing, drilling: larger diameter, higher hole processing accuracy, larger workpiece shape. There are many processing methods





7. CNC machining, wire cutting, etc.





8. Boring: main boring tool or blade boring inner hole;





9. Punching: mainly used for punching;





10. Sawing: Mainly cut by a sawing machine.











Third, production types are generally divided into three categories:











Single-piece production: Products of different structures and sizes are produced separately, rarely repeated.











Mass production: The same product is mass produced within one year, and the production process has a certain degree of repetition.











Mass production: To produce very large products, part of the process is often repeated in most workplaces.











Fourth, various machining processes of mechanical processing:











Special processing: Traditional processing methods mainly use electric energy, light energy, sound energy, thermal energy and chemical energy to remove metal and non-metal materials.





(2) Milling: According to the principle of tangential forming, the machining methods of milling planes, step faces, grooves, forming faces, cavity faces, and spiral faces with multi-blade rotary tools are introduced.





Tooth profile processing: can be divided into two categories: non-cutting and cutting, and cutting-based. Non-cutting methods include casting, hot rolling, cold extrusion, injection molding, etc. Cutting methods usually require cutting and grinding to obtain the desired gear accuracy.





Drilling: According to the shape of the handle, it can be divided into straight shank twist drills and tapered shank twist drills; according to the material, it can be divided into high-speed steel twist drills and cemented carbide twist drills.





Grinding: cutting methods for finishing and super finishing parts. Abrasive tools can be divided into ordinary abrasive tools and super hard abrasive tools.





Turning: This is one of the more widely used methods in machining. The spindle drives the rotation of the workpiece as the main motion, and the linear motion of the tool is used as the feed motion.
