    Precision machining is technically difficult, has many influencing factors, involves a wide range of areas, has a high investment intensity and a strong product personality. Its main elements are the following five aspects.   (1) Machining Mechanisms In addition to the precision of traditional machining methods, non-traditional machining (special machining) methods are developing rapidly. At present, the traditional processing methods mainly include diamond tool precision cutting, disk diamond micron grinding wheel precision grinding, precision high-speed cutting and precision abrasive belt grinding, etc.; non-traditional processing methods mainly include electron beam, ion beam, laser beam and other high-energy beam processing, electric spark, electrochemical processing, photolithography (etching), etc.. And there are compound processing methods such as electrolytic grinding, magnetic grinding, magnetic fluid polishing, ultrasonic honing, etc. with compound processing mechanism. The study of processing mechanism is the theoretical basis of precision and ultra-precision machining and the growth point of new technology.   (2) machined materials Precision machining of machined materials in the chemical composition, physical and mechanical properties, chemical properties, processing performance are strict requirements, should be uniform texture, stable performance, external and internal are no macroscopic and microscopic defects. To meet the performance requirements of the machined material to get the expected effect of precision machining.   (3)Processing equipment and process equipment Precision machining should have high precision, high rigidity, high stability and automation of machine tools, the corresponding diamond tools, cubic boron nitride tools, diamond grinding wheels, and cubic boron nitride grinding wheels. And the corresponding high-precision, high-rigidity fixtures and other process equipment in order to ensure the quality of processing. Precision machining should first consider having the corresponding precision machining machine tools, many precision machining is often from the design and production of ultra-precision machine tools to start. And to configure the required tools. At present, the general series of precision machining machine tools are fewer. The batch size will not be large. Precision machine tool cost is very high, need to special order, if the existing precision machining machine processing still can not meet the requirements. Can be through process measures or error compensation to improve processing accuracy.   (4) Detection Precision machining must have the corresponding detection technology, the formation of processing and testing integration. For precision machining detection there are three ways: offline detection, in-situ detection and online detection. Off-line detection refers to the completion of processing, the workpiece will be sent to the inspection room to test; in situ detection refers to the workpiece is not removed after the completion of the processing on the machine tool, in situ testing, if found to have any problems. To facilitate re-machining; online inspection is in the process of processing to detect, so as to be able to actively control and implement dynamic error Park compensation.

What is the order of precision parts machining? For the machining industry, the order is very important, it is related to the quality assurance of the product, there is a wrong order, it is easy to cause great losses, and serious words to start over, a little serious, is that these products are scrapped, precision parts processing is one of them, then what is the order of it? First, the arrangement of precision parts machining sequence should be considered according to the structure of the part and the condition of the blank, as well as the need for positioning clamping, with emphasis on the rigidity of the workpiece not destroyed.   (1) the processing of the upper process can not affect the positioning and clamping of the next process, interspersed with general precision parts processing process should also be taken into account.   (2) Inner cavity processing is carried out first, followed by shape processing.   (3) The same positioning and clamping method or the same tool processing process should be connected to reduce the number of repeated positioning, the number of tool changes and the number of times to move the platen.   (4) For multiple processes in the same installation, the process that causes little damage to the rigidity of the workpiece should be arranged first. Second, the tool is concentrated in the sequence method to divide the process according to the tool used, with the same tool to finish processing all the parts that can be completed. In the second tool, the third is to complete the other parts they can complete. This can reduce the number of tool changes, compress the empty range time, and reduce unnecessary positioning errors. Third, the processing parts are in order for the processing of many parts, according to its structural characteristics of the processing part into several parts, such as internal shape, shape, surface or plane. Generally first processing plane, positioning surface, after processing holes; first processing simple geometry, then complex geometry; first processing lower precision parts, then processing higher precision requirements. The above is the order of precision parts processing, which must be in accordance with these articles to operate, which will make your processing risk greatly reduced.

Our manufacturing network of over 1,000 manufacturers in China and overseas provides the production capacity you need to prototype and produce. Surface Treatment Services   We offer a variety of post-treatment and surface treatment services for CNC machined parts and sheet metal. Post-treatments are designed to improve the characteristics of the part, including surface finish, general durability, corrosion resistance and appearance.   Painting Services   Galvanized Use: Zinc coating (galvanizing) protects parts from rusting. Applicable materials: This method is suitable for steel and iron. Nickel and Chrome Plating Uses: Nickel and chromium coatings (electroplating) are often used for decorative and anti-corrosion purposes, or to increase surface hardness. Applicable materials: This method is suitable for all parts made of metal. Anodizing: Hardness and color Uses: Anodizing protects parts from corrosion, improves durability and makes parts non-conductive. After anodizing, the parts can be colored. Applicable materials: Anodizing is only suitable for aluminum and titanium. Available colors: Black hard coat, black, blue, gold, grey hard coat, green, natural hard coat, natural, orange, red.   Surface Treatment   Polishing Use: The purpose of using polishing is to remove marks left by CNC machining, contamination and oxidation and to improve the appearance of the part. Applicable materials: Applicable to all materials. Sandblasting Purpose: The pearlescent treatment is mainly used to improve the appearance characteristics of the finished parts. Applicable materials: Applicable to all materials. Paint and powder coating Uses: The purpose of powder coating is to increase the smoothness of the surface and make the parts resistant to corrosion. Powder coating can also be used for coloring purposes. Applicable materials: Applicable to all materials.   Heat Treatment   Quenching and Tempering Purpose: Quenching aims to increase the surface hardness of the part. Tempering reduces the brittleness of the part. Applicable materials: This method is mainly suitable for steel alloys. Normalizing and Tempering Purpose: The normalizing or annealing process stabilizes the part’s mechanical properties by stress relieving the CNC machined part, while tempering reduces the brittleness of the part. Applicable materials: Stress relieving is suitable for all alloys. Tempering is only suitable for steel alloys.
