1. Today, asset precision opinion on whether CNC has a future. First of all, what is CNC?2. How much is the salary for cnc machine tools? Is there a future?3. Better than ordinary workers, with higher status 4. As long as you are willing to learn and bear hardships, it may be good to become a manager 5. You can start your own business in CNC processing
Numerical control machine tool is composed of NC system, servo system, position detection, strong electric part and the body of the machine tool. It is much more complex than the general machine tool, and the surface form of the fault is more complex. This requires maintenance personnel to master several maintenance methods, meet different faults to flexibly use different methods, and strive to eliminate faults in the shortest time to ensure the normal operation of machine tools.
High precision CNC machining center is a milling machine that automatically processes workpieces with digital quantity sent out by digital control system as command information. In the whole digital control system, operations such as spindle start and stop, spindle speed change, tool advance and retreat, tool and workpiece relative displacement are all digitally represented, which greatly improves the stability of the whole processing process, thus improving the processing accuracy of NC milling and reducing processing errors.
Wet etching is a kind of etching method, which is a technology of immersing etching materials in etching solution for corrosion. It is a pure chemical etching with excellent selectivity. After etching the current film, it will stop without damaging the film of other materials below. Because all wet etching is isotropic, the width of transverse etching is close to the depth of vertical etching, no matter the etching of oxide layer or metal layer.
According to the type of metal, the etching process will be different, but the general etching process is as follows: metal etching plate → cleaning degreasing → washing → drying → film covering or screen printing ink → drying → exposure drawing → development → washing drying → etching → stripping → drying → inspection → finished product packaging.
Chemical etching is a technique in which materials are removed by chemical reaction or physical impact. Etching techniques can be divided into "wet etching" and "dry etching" two categories.
Metal etching(chemistry etching) technology is a technology that uses chemical strong acid corrosion, mechanical polishing or electrochemical electrolysis to treat the surface of objects. In addition to enhancing aesthetics, it also increases the added value of objects. From traditional metal processing to high-tech semiconductor manufacturing, they are all within the application scope of metal etching technology.
Compared with castings and forgings, metal stamping are thin, uniform, light and strong. Metal stamping can produce workpieces with stiffeners, ribs, undulations or flanging that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision mold, the precision parts of the workpiece can reach the micron level, and the repetition precision is high, the specification is consistent, and the holes and sockets, bosses, etc. can be punched.
Metal stamping process is a metal processing method, it is established on the basis of metal plastic deformation, the use of mold and metal stamping equipment to exert pressure on the sheet metal, so that the sheet metal plastic deformation or separation, so as to obtain a certain shape, size and performance of the parts (metal stamping parts).
Metal stamping is also called sheet stamping or sheet forming, but with a slight difference. The so-called sheet forming refers to the sheet, thin wall pipe, thin profile as raw materials for plastic processing of the forming method collectively known as sheet forming, at this time, the deformation of the thick plate direction is generally not considered. Generally carried out at room temperature, sometimes also called cold stamping. It is the use of metal stamping equipment (press) and punching die to make a variety of different specifications of sheet material or blank under the action of pressure permanent deformation or separation, made into a variety of shape parts required by a processing method. Cold stamping can be used to process metal materials, can also be processed non-metallic materials.

In order to improve the quality of CNC machining parts, it is crucial to find out the main factors that cause processing errors. Later, corresponding measures are needed to reduce or control these factors. Next, we will introduce five methods to improve the machining quality of metal parts:
There are photochemical etching companies all over the world. Everyone wants to find a nearby metal etching factory, but if you want to find a parent to cooperate and have a certain scale, there are few chemical etching processes or sub processes with excellent technology. The following are Anshi Metal finishing collections for reference!
Metal etching is a technique to remove materials by chemical reaction or physical impact. metal etching technology can be divided into wet metal etching and dry metal etching. Metal etching principle. technological process. The metal etching process removes the film layer not covered by the resist, so as to obtain the same pattern on the film as that on the resist film.
