Mechanical processing is a process of transforming the shape and geometric parameters of the workpiece by using relevant technologies and equipment to provide necessary components for social production. In this process, the accuracy and efficiency of the processed workpiece determine the value of the product.
In the production and manufacturing of gears, the mechanical processing will make the workpiece from the initial blank production to the complete forming of the workpiece. It has gone through a series of processes and a series of measurements to ensure the product quality, so the mechanical processing is a particularly important part. Of course, in addition to the precise control of each process, the processing equipment and workpiece also have an important impact.
The product is completed by every cutting and cutting, so the performance and quality of the tool will also affect the quality of the processing components. With the improvement of machining quality requirements, people have more strict requirements for gear processing technology, which makes people focus on cutting technology. From the perspective of tool performance, in order to further improve the quality and accuracy of cutting, the material of the tool should be considered. Therefore, the research and development of new materials and coating protection technology began to have new development.
The new materials are mainly cemented carbide, such as titanium nitride alloy. This kind of alloy has good advantages in toughness, hardness and wear resistance, and has a good effect on improving the performance of cutting tools, which will also be the trend of future development. On the other hand, coating protection technology can also play a role in improving tool performance. Coating protection technology is a kind of material surface modification technology. Its principle is to apply physical or chemical action to cover one or more layers of coating on the material surface, thus changing the material surface structure and achieving the purpose of improving the material surface performance. At present, this technology has been widely used.
This technology has obvious effect on improving the overall toughness, wear resistance and corrosion resistance of the tool by coating the material with excellent performance on the tool surface, thus further improving the precision and quality of gear machining, and achieving the goal of optimizing gear machining.
