Under the influence of the rapidly discovered technology, the processing technology is also constantly improving. In order to solve the non-conductive non-metallic materials that cannot be easily processed, ultrasonic processing came into being. This kind of machining solves the defects of previous EDM intelligent machining of metal materials, so that non-metallic brittle and hard materials can also be machined. The future development of ultrasonic machining is very promising. Here is a detailed introduction from many aspects.
1. Two dimensional ultrasonic technology
With the increasing difficulty of machining materials, especially for some aerospace parts, one-dimensional ultrasonic machining can no longer meet the production needs of high standards and strict requirements, so two-dimensional ultrasonic machining technology was born at this time. Now this technology has been attached importance to by advanced countries. In the United States, Germany, Britain and Singapore, two-dimensional ultrasound technology has been studied.
Under the influence of ultrasonic elliptical vibration cutting, the arc radius of cemented carbide tool tip has many geometric shapes, especially the influence of the element and radius of the tool on one-dimensional ultrasonic vibration cutting performance. Due to the rapid wear of the tool, brittle materials are easy to break and stick to the tool, making the traditional vibration cutting accuracy results are not accurate. Ultrasonic elliptical cutting can solve this problem well, and get a practical ultra precision mold, which can be successfully applied to the forming of glass.
2. Ultrasonic vibration cutting technology
This technology is created in practice. The process experiment of ultrasonic vibration cutting is carried out on the hobbing of spur gear produced by FAW gearbox factory,. And restore various processing parameters on the production site for small batch trial production, and obtain satisfactory results.
With the wide application of this method, the following aspects can be studied: the use of new tool materials and efficient vibration cutting system, and the in-depth study of vibration cutting machine.
3. Micro ultrasonic machining
In principle, micro ultrasonic machining is very similar to conventional ultrasonic machining, which is also achieved by reducing abrasive particle size, tool diameter and ultrasonic amplitude. Micro ultrasonic machining has its own advantages. Compared with traditional machining technology, ultrasonic machining has no great requirements for the conductivity and thermophysical effects of materials, and can process three-dimensional shapes, which determines the particularity of micro ultrasonic machining in the processing of non-metallic materials.
4. CNC Ultrasonic Machining
Numerical control is the development trend of mechanical equipment in the future. In China, in the processing and production of manufacturing industries and enterprises, traditional machine tools still account for a large proportion. Milling machines, grinders, lathes, drilling machines, boring machines, etc. all of them use their cutting tools to do the corresponding linear motion, but slowly these accuracies can no longer meet the current needs. The application of ultrasonic technology to CNC machine tools can make the cutter obtain irregular movement mode and further improve the machining accuracy.
Ultrasonic machining is now more and more widely used in production and processing, because it overcomes the shortcomings that it is not easy to be processed, effectively improves the processing accuracy, shortens the processing time, and brings convenience to production and processing.
