                                                                     What are the factors affecting the machining accuracy of mechanical parts?




When using lathe machining, operations such as driving, parking, cutting, reversing, spindle shifting and switch cutting are manually controlled; when CNC lathe machining is performed by automatic machine tools and profiling machines, the above operation and motion parameters are used. It is controlled by analog devices in the form of designed cams, cams and stops, and it can process more complicated parts with certain flexibility and versatility. However, the machining accuracy of the parts is affected by the manufacturing precision of the cam and the master, and the process preparation time is also long.

In the mechanical parts processing industry, the accuracy requirements of the products are relatively high. So what are the factors affecting the machining accuracy of mechanical parts? Let me introduce you to the following small series:

 1. When we use lathes to machine parts, it is usually necessary to control the various actions of the machine tool. One is to control the sequence of actions, and the other is to control the displacement of each moving part of the machine tool.

 2. When replacing the processing object, only need to re-write the program code and input it to the machine tool, then the CNC machine can replace most of the functions of the human brain and hands, control the whole process of processing, and manufacture arbitrarily complex parts.

 3. When machining parts with CNC lathe, only part graphics, process parameters, processing steps, etc. need to be programmed into the machine control system in the form of digital information, and then converted into drive servos by arithmetic processing. The command signal, which controls the coordinated action of the various parts of the machine tool, automatically processes the parts.

                Ten things that must be paid attention to in precision casting! 1. Unblock all obstacles to the channel and site. 2. Check if the ladle is dry, whether the bottom of the bag, the ear, the bag and the end are safe and reliable, and whether the rotation is flexible. Do not use dry Iron ladle. 3, all tools in contact with molten iron, must be preheated to 500 degrees Celsius before use, otherwise it should not be used. 4, the ladle should not exceed 80% of the volume, the ladle should be smooth and slow, keep the steps to prevent the overflow of molten iron. Cast iron 5, before the crane crane should check the iron of the hook, the chain is reliable, the chain is not allowed to knot, there is a person responsible for tracking the iron in the water There must be no staff on the line. 6. Strictly implement the "six will not fall": (1) The temperature of molten iron is not enough; (2) The molten iron grade is not poured; (3) does not b

                                                                   Factors affecting the surface roughness of stainless steel castings Surface roughness is another major quality indicator for stainless steel castings , generally less than 3.2 μm, between 0.8 and 3.2 μm. There are many factors affecting the surface roughness of castings, such as the pressure type, the surface quality of the investment and stainless steel, the casting process, the type of alloy and other factors. (1) Profile and investment surface quality. The surface roughness of the investment mold is the most important part affecting the surface roughness of the casting, and it is related to the surface quality of the molding, the compression molding method and the pressing process parameters. (2) Stainless steel surface quality. Stainless steel is a columnar columnar structure network, and refractory materials, additives, and water are filled in the middle, so that there are pores of different sizes on the su
