Precision machining is a total process of changing the size or performance of a product workpiece with machining equipment. It is divided into cold machining and hot machining according to the temperature of the product workpiece being machined. The process is usually done at room temperature and does not lead to chemical or physical transformation of the workpiece. Usually in the higher or less than room temperature production processing, will lead to the chemical or physical transformation of the product workpiece, called thermal processing. Next, with Shenzhen Perfect Precision Products Co. to learn the main uses of thermal processing. Precision machining is a kind of machining manufacturing, which is also a kind of machining parts to achieve the line position tolerance required by the design drawings of the production process, the product workpiece in the development of this process, will be the use of its own performance characteristics and its appearance structure caused by the corresponding transformation . Along with the development of the domestic manufacturing industry continues to progress, machining manufacturing has changed a lot, Dongguan precision machining technology applications are also outstanding, many manufacturing industries such as household appliances, vehicles, hardware accessories and their medical production applications of product workpieces more or less use high-precision spare parts. It may be a kind of spare parts, may also be a mechanical equipment manufacturing in the key components. After the raw material and blank type of mechanical parts are determined, the mechanical properties of the material required to complete the parts are mainly ensured by the heat treatment process. So must be in accordance with the purpose of heat treatment and process technology function, the appropriate arrangement of heat treatment process technology in the specific location of the production process pathway. Annealing process and normalizing process technology specific location is usually allocated in the blank production and manufacturing after, cutting production processing before. In high-precision spare parts, in order to better remove the residual stress of cutting production and processing, the cutting production and processing technology should also be allocated between the stress relief annealing. The process technology is distributed as follows: billet manufacturing (casting, forging, welding, stamping, etc.) - annealing process or normalizing - machining manufacturing. Relative to the surface quenched parts, in order to better enhance the mechanical properties of its heart material and get fine crystal martensite organization of the surface quenching organization, often first to carry out normalizing or quenching treatment. Because of the small deformation of the surface hardened parts, their grinding allowance should also be smaller than that of the overall hardened parts.

CNC machining refers to the production and processing with CNC machining tools, and is a kind of mechanical automation machine tool controlled by a program. The control system can logically handle the program with manipulation code or other symbolic control instructions, with the help of the computer will be decoded, and then make the machine tool operation and parts processing, with the help of CNC tool cutting will be the production of raw material processing into semi-finished finished parts and so on. Medium and large machinery factory in the machining manufacturing to pay special attention to more issues, such as medium and large machinery factory production safety regulations, medium and large machinery factory production process technical regulations, machining manufacturing should be strictly observed in the technical specifications and requirements. In the mechanical processing process issues to pay special attention to the problems are also quite a lot, the following let's take a look at it! 1. When the product workpiece is too high, it should correspond to the choice of different specifications of the knife to open the rough, and then use a small knife to remove the edge of the remaining material. 2. High material hardness should be selected for reverse milling; low material hardness should be selected for smooth milling; finish machining should be selected for reverse milling and finish machining should be selected for smooth milling. 3. mechanical parts processing clamping method to reasonably select the fixed benchmark and clamping method. When we select the fixed benchmark, let us follow the "benchmark unity" and "benchmark overlap" 2 basic principles. 4. Determine the product workpiece on the workbench place, must take into account each place of production processing, CNC tool specifications and CNC tool rigidity on the production and processing of product quality impact. 5. In the machining manufacturing selected tooling fixture, should try to select by the universal parts assembly, and can come to adjust the tooling fixture, can reasonably and effectively reduce the production preparation cycle time. 6. All the surface production and processing as far as possible in a fixed fixture, so it is necessary to select a convenient product workpiece each surface can be produced and processed to the fixed method. Before CNC processing, the machining center machine operator should select a good production processing solution based on the product workpiece specification accuracy, the size of the skew angle, the look of the CNC tool, the clamping method of the parts and the difficulty level of programming and other elements, combined with the considerations before CNC processing.

Non-standard custom parts for the product's non-standard parts. Non-standard parts are not based on the consistent requirements and specifications of the manufacturing industry, in line with the development of the multifaceted requirements and specificity of product manufacturing. Its appearance or characteristics do not belong to the domestic equipment commodity catalog, the project cost and cycle time will be relatively higher than the standard parts products. Along with the modern society, the requirements for the role of the current production and processing products become higher and higher. At the same time also in the corresponding degree reflects the current society to the production and processing of non-standard parts situation. And non-standard mechanical parts processing technical specifications and requirements become more and more demanding, the following together with the editor to understand the non-standard mechanical parts processing it! Mechanical equipment parts, is the standard and non-standard classification, standard parts refers to it has the corresponding requirements definition, non-standard parts and there is no consistent requirements, non-standard mechanical parts processing is the use of production processing machinery and equipment to these parts of the extra parts grinding or cutting off, so that a whole non-standard parts look better, and at the same time can also make everyone better use. Standard parts refers to the general rules of general-purpose machinery that can be used according to the state's manufacturing scale, in turn, non-standard mechanical parts processing must be based on the actual requirements, which processing parts only manufacturers have their own, non-standard mechanical parts processing is the biggest advantage of custom-made production processing. Non-standard mechanical parts processing is 1 kind of production and manufacturing links. Contains a set of non-standard non-standard forming operations based on data lathes and other production and processing machinery and equipment to remove the material (based on industrial equipment cutting or based on wear and tear). The production and processing of non-standard parts requires the use of special industrial machinery and equipment designed for the processing of non-standard mechanical parts, the style of non-standard parts and non-standard parts specifications to carry out the required production and processing and update the transformation. Non-standard non-standard production and processing methods will be based on the categories and characteristics of items using two different production and processing methods. All metal non-standard mechanical parts processing (castings are not included) in its manufacturing process at least in one of the links have undergone a metal forming operation, and often need to come to a number of different operations, metal forming theory can help how to use the machine tool equipment in a more efficient way, as well as to improve productivity. The whole process of machining non-standard mechanical parts requires a very strict professionalism. Because the only way to make non-standard mechanical parts processing non-standard parts, so that the non-standard mechanical parts processing products more accurate, such precise and demanding requirements.

Mechanical spare parts processing refers to the parts or components of the installation mold; it can also refer to the mold parts or components that are re-installed on after damage. Precision molds usually consist of many parts, which can be divided into two categories: process parts and structural parts. Process parts can directly affect the quality of the forming product, and the decisive quality of the process parts are finished by finishing techniques in the current precision mold parts. Mechanical spare parts processing progress is related to each other to the service life of precision mold and forming products, in the precision mold parts production and processing of finishing stage in addition to the choice of slow wire cutting, EDM forming and other technological practices, the other method is selected after the semi-finishing process, heat treatment based on grinding processing. Then in the precision mold parts production processing grinding processing stage need to control the deformation of the parts, internal stress, shape public service and scale accuracy and many other technical parameters. In the complete production practice, the actual operation is more difficult, but in the hold Chuang 15 years of personal experience in precision processing can be summarized and analyzed to be able to learn the method: from the mold finishing progress adjustment precision mold parts production processing, we can specifically for different mold parts, different materials, different shapes and different technical requirements for adaptive production processing, supply selective program. After the adjustment of the production and processing progress, to achieve a better production and processing role and economy is the key to most precision mold parts processing enterprises attach great importance to. The process progress of production and processing of precision mold parts is usually as follows: rough machining - semi-finishing machining - (quenching, tempering) - precision grinding - electric machining - clamping trimming - assembly production processing.

Precision machining, there will be a number of products workpiece is not through a one-time production, but rather when the product workpiece is produced, it is only a rough model, if the factory into a real product, which also requires the use of some mechanical equipment for precision machining, precision machining for different product needs, and finally to become a product with value. In order to ensure the efficiency of precision machining, and the production of qualified products, in the time of precision machining, must follow the four principles. 1, the benchmark first. In the use of machinery and equipment for product processing, must determine a datum, so that in the subsequent production and processing time so that there will be a positioning reference, clear datum, then we must first produce and process the datum. 2, divide the production and processing stages. Products in precision machining, for different product requirements to different degrees of production processing, the degree of production processing needs to be divided, if the requirements for precision is not high, so then a simple roughing stage on the line. The progress of the product requirements are becoming more and more stringent, and the semi-finishing and finishing stages will be carried out later. 3、Face first and then hole. In the time of precision machining, for products such as bracket workpiece, it is necessary to carry out both plane production processing and mechanical hole processing, in order to be able to produce and process the hole accuracy error is smaller, first production and processing plane after production and processing hole is conducive to reducing the error. 4、Light finishing processing. This production and processing of the basic principles is largely some grinding and polishing processing, it is generally in the product after all the steps to complete the architecture.
