Shaft refers to a shaft with high precision requirements such as roundness runout. Some shafts that require high precision, such as roundness runout, are also called shaft cores. Often non-standard parts, customized processing according to customer sample or drawing requirements. The reference axis can be used in many applications, such as automotive parts, office automation parts, household appliances parts, and power tool parts.
Super machining technology is a processing method to reduce the surface roughness of the workpiece, remove the damaged layer, and obtain surface integrity. At this stage, the super machining on the premise of not changing the physical properties of the workpiece material needs to make the shape accuracy and surface roughness of the workpiece reach Sub-micron, nano-level, and even non-damage polishing technology that pursues high surface integrity.
Complex curved surfaces are generally composed of curved surfaces with multiple curvatures, which achieve certain mathematical characteristics and pursue functional and aesthetic appearance forms, including aspherical surfaces, free-form surfaces, and special-shaped surfaces.
Complex curved surfaces have become important working surfaces for many industrial products and parts such as aerospace, astronomy, navigation, auto parts, molds, and biomedical implants. For example: aspheric optical parts can well correct a variety of aberrations and improve instrument discrimination; complex curved mirrors can reduce the number of reflections and power loss, mentioning stability; complex curved engine cylinders can improve work efficiency; at the same time, some More and more complex surface shapes are used in mold cavities and auto parts to meet functional requirements and aesthetics. With the increase in demand for complex surface parts and the continuous improvement of performance requirements, traditional processing methods have been unable to meet the needs of practical applications. There is an urgent need to further improve the processing level of complex surface parts in order to achieve super processing. Due to the variability of the curvature of complex curved surfaces, the study of material removal mechanisms, subsurface damage and other characteristics is important to improve processing accuracy and efficiency, and the pollution of processing residual waste has attracted widespread attention.
Summarize the research progress of super-machining methods for complex curved surfaces, review the development of super-machining of complex curved surfaces, explain the principles and influencing factors of super-forming and super-polishing of complex curved surfaces, and compare the fit and accuracy of machining tools and workpiece surfaces in super-processing of complex curved surfaces. , Surface damage, efficiency and other factors, and then forecast and prospect the super-processing methods of complex curved surfaces.
The process of parts processing is a process of directly changing the appearance of raw materials to make them semi-finished workpieces or finished products. This process is called the process flow, which is the benchmark of the machining process of the parts, and the process flow of the machining of mechanical parts. Add complexity.
The machining process standards of mechanical parts can be divided into categories according to different processes: casting, forging, stamping, welding, heat treatment, machining, assembly, etc. It refers to the general term of the entire parts of the CNC machining and machine assembly process, and other such as cleaning, inspection, equipment maintenance, oil seals, etc. are just auxiliary processes. The turning method changes the surface properties of raw materials or semi-finished products, and the CNC machining process is the main process in the industry.
Process benchmarks for machining mechanical parts include positioning benchmarks, which are used by lathes or fixtures when machining on a CNC lathe; measurement benchmarks, which usually refer to the size or position standards that need to be observed during inspection; assembly Datum, this datum usually refers to the position standard of parts during the assembly process.
The processing of mechanical parts requires the production of stable products. In order to achieve this goal, the staff must have rich experience in mechanical processing and technology. As we all know, mechanical processing is the same job, and it needs technology to do it well.
Secondly, whether the machining process of mechanical parts is standardized also determines whether the product is good. Both production and management must require a set of processes, and the process is for the production of products and services. Thirdly, communication should be emphasized in the production process. Whether it is node time or when there are problems, communication must be strengthened. Communication between processing plants and equipment manufacturers is an important condition for processing automation equipment parts.
In terms of machining tools, the diamond grinding wheel is mainly used in the process of operation to control the amount of back-grabbing and feed to a certain degree. It can be carried out during operation on an ultra-grinding machine.
Ductile grinding, that is, nano grinding. Even the surface of glass can obtain an optical mirror surface.
Machining processing and super processing can obtain the surface quality and surface integrity to the extent, but the processing efficiency can be sacrificed. When the drawing method is used, the larger deformation force is only 17t, and when the cold extrusion method is used, the deformation force is 132t. At this time, the unit pressure acting on the cold extrusion punch is more than 2300MPa. In addition to the mold needs, it also needs to have sufficient impact toughness and toughness.
The machined metal blanks are strongly plastically deformed in the mold, which will increase the mold temperature to about 250°C to 300°C. Therefore, the mold material needs tempering stability. Due to the above situation, the life of cold extrusion dies is much lower than that of stamping dies.
Machining is pursuing the high quality of the product to the degree. During operation, the bearing and other parts that bear the load while doing relative movement can reduce the surface roughness during operation, so that the damage of the parts can be improved, and the work can be improved. Stability and extended service life. Si3N4 used in high-speed and high-speed bearings. The surface roughness of the ceramic ball is required to reach several nanometers. The processed metamorphic layer is chemically active and susceptible to corrosion. Therefore, from the perspective of improving the capabilities of the parts, the processed metamorphic layer is required to be as small as possible.
