Effective Improvement Measures to Improve The Processing Quality Of Titanium Fasteners
1. Strengthen The Control Of machining And Production Equipment
In the process of mechanical production and processing of titanium alloy fasteners, the requirements for equipment and the regulation of equipment are relatively higher to ensure the accuracy of the equipment during the processing process. On this basis, the processing of the program can allow the fasteners to be processed and produced within the error range. When choosing a cutting tool during processing, material considerations are required. It is necessary to consider the degree of damage resistance of the processing tool and the density of the processing tool, what is the stiffness of the processing tool, and whether it can cut titanium alloy-related materials. During the processing process, the coolant of the machinery also needs to be controlled in time. If the mechanical coolant is too small, it will affect the precision of the processing process. If the coolant is found to be too small, the coolant should be added in time.
When choosing a tool for processing titanium alloy fasteners, because titanium alloy materials have relatively higher stiffness and density, when choosing a tool, choose a tool with a higher density as much as possible. During the processing process, because the cutting of the tool will cause high temperature, under high temperature conditions, it is necessary to ensure that the materials of titanium alloy fasteners and the tool will not be affected, so when choosing materials, you need to choose materials with high temperature resistance.
In the process of machining, it is also necessary to take into account the degree of sealing of titanium alloy fasteners and the degree of roughness of the surface. During processing, the surface needs to be polished to ensure that the fasteners can be accurately connected to titanium alloy materials and other materials, so when choosing the coating material on the surface of the fastener, it is necessary to analyze and choose.
Since titanium alloy materials are easy to deform during machining and production, and the elastic modulus of titanium alloy materials is relatively small, the requirements for fixtures are relatively high during the processing process. In the process of mechanical production and processing, the clamping force of the fixture should not be too large. When clamping titanium alloy materials, auxiliary fixtures can be selected. These processing problems need to be taken into account in the design of the fixture, so that the related problems of deformation of fasteners during processing can be avoided.
2. Control The Selection Of Raw Materials For Machining
In the process of machining and production of titanium alloy fasteners, the selection of titanium alloy raw materials must be controlled in place. The material selection requirements for titanium alloy fasteners are higher. When choosing, the relevant testing standards for the materials must be strictly implemented in accordance with the fastener standards. During the testing process, it is necessary to ensure that the performance of the fastener material meets the requirements.
Processing on this basis, it is not easy to have processing problems during the processing process, and the product's testing certificate and all aspects of the product's performance index indicators need to be collated and classified. There are many related performance indicators for testing fasteners, such as the specifications, quantities, and dimensions of the materials used, as well as the mechanical properties, corrosion resistance, and high temperature resistance of the materials. Performance testing.
3. Improve the Working Environment for Machining and Producing Fasteners
In the production process of titanium alloy fasteners, the environmental control of the machining and production process is relatively more demanding. In the required processing environment, titanium alloy fasteners can be processed to a higher standard, with better fastening performance and better sealing performance. When the product is used, there will be no related quality problems when connecting the titanium alloy. During the mechanical production process of fasteners, there will be requirements for the temperature of the processing environment and the humidity of the processing environment around the processing.
Because the fastening parts produced are titanium alloy-related materials, they are easy to oxidize in the environment. If the temperature and humidity are too high, it is easy to produce chemical reactions during contact with other materials, especially some chemical materials such as metal aluminum and metal lead, which are more likely to cause secondary chemical reactions. Fasteners produced in this processing environment cannot be used normally. Therefore, During the processing of titanium alloy fasteners, the factory needs to take environmental protection measures to avoid mixing fasteners with other metal products. When controlling the processing environment, it is necessary to have relevant equipment and instruments and do a good job of management.
4. Strengthen Machine Tool Control in Fastener Production Workshop
The machine tools for the production of titanium alloy fasteners need to be strictly controlled. The precision of the machine tools and the precision of the sharpeners on the machine tools, the quality of the sharpeners, and the materials of the sharpeners need to be controlled, and they need to be produced strictly in accordance with the standardized production requirements within the standardized error.
The first aspect that needs to be controlled is the structure of titanium alloy machine tools. In the production process of parts, the load that needs to be borne will be greater, and the tension that needs to be borne will be greater. Therefore, the entire machine tool needs to meet the technical requirements of these aspects, and be prepared to reduce the punching of titanium alloy materials in areas with relatively large tensile forces. When punching, it should be in an area with relatively small tensile strength, so that the accuracy requirements of the titanium alloy fastener material can be guaranteed, and the roughness of the material surface can be guaranteed.
When using lathe technology, relatively advanced lathe processing and production technology at home and abroad should be used. When introducing lathes, as far as possible, we should have an overall understanding of the processing links of titanium alloy materials. In the process of production machining, it is necessary to ensure the accuracy of titanium alloy punching, especially when using high-hardness and high-stiffness material knives. When punching, it is necessary to ensure that the degree of wear on the knife surface is within a certain range, so as to be able to meet the production requirements of titanium alloy fastener materials. It is necessary to repair and polish the overall tool after each processing and production, and to ensure that the tool is always within the error range, so as to ensure that the entire titanium alloy material meets the technical requirements during the machining and production process.
5. Strengthen The Quality Control In The Production of Fastener Machinery
Titanium alloy fasteners need to control the quality requirements of the processed fasteners during the processing process, which is quality control. When it comes to quality control, the quality control of lathes, the control of tools, the control of processing materials, the control of the workshop environment, etc. all need to be strictly checked, and the relevant performance of the product needs to be tested regularly. During the process of reprocessing when the product is polished, it is necessary to ensure the normal operation of mechanical production. Regular inspections of machinery are also required.
In terms of quality control, due to the many special properties of titanium alloy materials in all aspects, it is necessary to cool the materials and protect the materials during the cutting and processing process, especially in this high-temperature processing environment. It is necessary to do a good job in safe processing to reduce the chance of hidden dangers in the processing plant. Talcum powder can be used for fire extinguishing related treatment work. These should be prepared with relevant plans and measures before the fastener is processed. If there is an emergency, it must be dealt with in time, especially when there is an emergency, titanium alloy materials can easily react chemically with other materials, thereby exacerbating the severity of the emergency. This is the quality control that needs to be done during the machining process.
In general, titanium alloy materials have been widely used in recent years. In the process of machining fasteners, factories should also take relevant processing precautions and make basic processing-related preparations. When machining, know the shortcomings of titanium alloy fastener processing, know how to improve the shortcomings in the processing technology, and constantly improve the requirements of the enterprise's production workshop. I believe that in this way, high-quality and high-precision fastener products can be produced.
