Chemical etching is to selectively remove the part of the film layer that is not masked by the resist by chemical, physical or chemical and physical methods at the same time, so as to obtain completely consistent patterns on the film and the resist film. Chemical etching technology is mainly divided into dry etching and wet etching. Dry etching mainly uses reactive gas and plasma for etching; Wet etching mainly uses chemical reaction between chemical reagents and the chemical etching material to etch.

What is the Metal Fabrication Process? Mold production, metal stamping processing, die casting, laser cutting, batch of front, welding and pot needle, metal polishing, electroplating, paint, coloring, screen printing processing, rhinestones, a glue, Car ribbon, installation, packaging, quality inspection, Metal machining Production flow sheet
The way metal parts are made can vary greatly. Each process has its own advantages, compatible materials and trade-offs. A better understanding of the scope of production methods will improve this decision-making process. This is an overview of eight different manufacturing processes that can be used to create custom metal parts. These are:
Relative to the ordinary lathe, CNC machining CNC milling machine with constant line speed drilling effect, whether for the interior hole or not straight through the inner hole can be processed with the same angular speed, that is, to ensure that the surface surface roughness value is common and relatively small. And the ordinary lathe is stable speed ratio, straight cutting parameters are not the same. Under the condition that the raw materials, finishing capacity and the Angle of view of the CNC blade are certain, the roughness of the outer surface depends on the cutting dosage and the cutting speed.
Fine parts CNC machining technology is the rule of the process and operation method of the process, it is in the detailed production conditions, the more reasonable process and operation method, in accordance with the rules of the form of writing into the process file, after review, used to guide production. Fine machine parts CNC machining process rules generally include the following contents: workpiece processing road, the detailed content of each process and the equipment and process equipment used, workpiece inspection items and inspection methods, cutting parameters, time quota, etc.
There are three kinds of compensation in CNC machining: These three kinds of compensation can basically solve the trajectory problem caused by tool shape in machining. The following one is the application of tool radius compensation in general CNC machining programming.
There are three kinds of compensation in CNC machining: These three kinds of compensation can basically solve the trajectory problem caused by tool shape in CNC machining. The following is the application of tool length compensation in general CNC machining programming.
For CNC machining precision parts designers and manufacturers, these products may have gone through months, sometimes even years of careful planning and diligent testing. CNC machining precision parts is an important link in the initial stage of product development in most cases. Whether it is to create a component or part of a product or to manufacture a prototype of a product, CNC machining itself does so.
Before metal parts processing enters the job position, check whether their clothing meets the job requirements. It is not allowed to wear slippers, high-heeled shoes and clothes that affect safety during metal parts processing. Those with long hair should wear safety helmets. Precautions and production steps for metal parts processing of Anshi.
The standard of precision CNC parts industry is very strict. There are different processes such as tool feeding and tool discharging during processing. The size will also vary according to the specific requirements of the product, and the requirements for processing accuracy will also vary. In general, the requirements for precision processing accuracy are very high, sometimes even to the number of micrometers below 1mm. If the size difference is large, the product will become a waste product, and it needs to be reworked to meet the requirements. This process is very time-consuming and laborious, and sometimes all raw materials will be scrapped, resulting in increased costs, At the same time, CNC is bound to be unusable, so there are many requirements for precision CNC machining. What are the requirements for precision CNC machining?
The machining accuracy of metal parts is the degree to which the actual size, shape and position of the machined part surface conform to the ideal geometric parameters required by the drawing. The ideal geometric parameter, for size, is the average size; For surface geometry, it means absolute circle, cylinder, plane, cone, straight line, etc; The mutual positions between surfaces are absolutely parallel, vertical, coaxial, symmetric, etc. The deviation between the actual geometric parameters and the ideal geometric parameters of a part is called machining error. Asset metal is the main product of the company with stainless steel parts processing, titanium alloy parts processing, steel parts processing, aluminum alloy parts processing, casting processing and metal surface treatment as its main products. Its quality assurance is reliable!
Metal parts in use are very common in our life, often involves the surface wear resistance and corrosion resistance of functional requirements, in order to improve the utilization rate of metal products, to do a good job of protection on the surface of the metal product is quite important, so the action of the metal parts processing is crucial, and the metal surface treatment processing way segmentation can be divided into: Baking Varnish processing, electroplating, Metal surface polishing processing, metal chemical etching and so on.
Metal etching, also known as chemical etching, is being used more and more in various fields, and people have more and more knowledge about etching. Today Asset metal will tell you something to pay attention to in metal etching production, let's have a look!
Precision metal etching is usually used to process some metal parts with complex shapes, various categories and high precision requirements. Asset metal believes that chemistry etching is used because many mechanical processes are difficult to completed or the cost is too high. Precise metal etching has the following advantages.
