CNC machining usually refers to computer digital control precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc.
CNC machining advantages:
1. The number of tooling is greatly reduced, and complex tooling is not required to process parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.
2. The processing quality is stable, the processing precision is high, and the repeatability is high, which is suitable for the processing requirements of aircraft.
3. The production efficiency is high in the case of multi-variety and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and reduces the cutting time due to the use of the optimal cutting amount.
4. It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.Automatic lathe is a high-performance, high-precision, low-noise tool-type automatic lathe. It is an automatic processing machine tool that controls the processing program through a cam (CNC is also a type of automatic lathe, here refers to a non-CNC automatic lathe).
Advantages of automatic lathe processing:
1. Automatic processing: no manual operation is required, and complex parts can be processed simultaneously with external circle, spherical surface, conical surface, arc surface, step, groove, embossing, drilling, tapping, die, cutting and other processes. It can be done in one processing.
2.High control precision: the precision of the machine tool spindle can reach 0.003mm, the fine adjustment of the slider is controlled by a micrometer, and the dimensional control precision can reach 0.005mm. The minimum cutting feed can be controlled to 0.005, and the roughness of the parts (copper parts) can be as low as Ra0.04-0.08.
3. Automatic feeding: the feeding mechanism automatically feeds the main shaft, and the machine automatically stops and alarms when the material is finished, and the processing process does not require manual viewing of the material, achieving a fully automated manufacturing process. One operator can operate multiple machines at the same time.
4. High production efficiency: a machining process is completed for each revolution of the cam. Multiple tools can be cut at the same time, the processing efficiency is very high, and the processing efficiency has the advantages that CNC can't match.Sheet metal processing is called sheet metal processing. Sheet metal parts are thin-plate hardware parts that can be processed by stamping, bending, stretching and other means.
The main processes are:
Pressure riveting, expanding riveting, pulling mother, pulling riveting, riveting, chamfering, bending, forming, cutting, blanking, blanking, punching, punching convex hull, punching and tearing, punching, tapping, leveling , Back teeth, drilling, chamfering, punching, countersinking, flattening, punching mesh, reaming.
The materials commonly used in sheet metal processing are cold-rolled sheet (SPCC), hot-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU), brass, red copper, beryllium copper, aluminum sheet (6061, 5052 , 1010, 1060, 6063, duralumin, etc.), stainless steel (SUS301, SUS304).
Stamping processing is the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the sheet metal is directly subjected to deformation force in the mold and deformed. It is one of the main methods of plastic working (or press working) of metals.
Advantages of stamping processing:
1.The production efficiency of stamping processing is high, and the operation is convenient, and it is easy to realize mechanization and automation. The number of strokes of ordinary presses can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute, and one punching piece may be obtained per stamping stroke.
2. Since the die ensures the size and shape accuracy of the stamping parts, and generally does not damage the surface quality of the stamping parts, and the life of the die is generally long, the quality of the stamping is stable and the interchangeability is good.
3. Stamping can process parts with a wide range of sizes and complex shapes, such as stopwatches as small as clocks, as large as automobile longitudinal beams, covering parts, etc., plus the cold deformation hardening effect of the material during stamping, the strength and stiffness of stamping are higher.
4. Stamping generally does not generate chips and scraps, consumes less material, and does not require other heating equipment, so it is a material-saving and energy-saving processing method, and the cost of stamping parts is low.
Surface treatment is a process of artificially forming a surface layer with different mechanical, physical and chemical properties of the substrate on the surface of the substrate.
The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product.
The most commonly used surface treatment processes are:
Anodizing, electrophoresis, electroplating, PVD, powder coating, metal wire drawing, sandblasting, polishing, etching, etc.
