Under the influence of the rapid discovery of science and technology, the processing technology is also in continuous improvement. In order to solve the problem of non-conductive non-metallic materials that can not be easily processed, ultrasonic machining came into being. This kind of machining has solved the defect of the previous intelligent EDM machining of metal materials, so that non-metallic brittle and hard materials can also be processed. The development of ultrasonic machining in the future is very promising, the hook net is introduced from many aspects.
1. Two dimensional ultrasonic technique
With the increasing difficulty of processing materials, especially for some aerospace parts, one-dimensional ultrasonic machining can not meet the production needs of high standards and strict requirements, so the two-dimensional ultrasonic machining technology was born at this time. Now this technology has been paid attention to by advanced countries. In the United States, Germany, the United Kingdom and Singapore, two-dimensional ultrasound technology has been studied.
In particular, the tool tip radius has an effect on the cutting performance of ultrasonic cutting tool, especially in the ultrasonic cutting tool. Due to the rapid wear of the tool, brittle materials are easy to break and stick to the tool, so the traditional vibration cutting accuracy results are not accurate. However, ultrasonic elliptical cutting can solve this problem and get practical ultra precision mold, which can be successfully applied to glass forming.
2. Ultrasonic vibration cutting technology
This technology is created in practice. The technology of ultrasonic vibration cutting is applied to the hobbing of straight tooth gear produced by FAW gearbox factory,. At the same time, various processing parameters on the production site are reduced for small batch trial production, and satisfactory results are obtained.
With the wide application of this method, the following aspects can also be studied: the use of new tool materials and efficient vibration cutting system, in-depth study of vibration cutting machine.
3. Micro ultrasonic machining
The principle of micro ultrasonic machining is similar to conventional ultrasonic machining, and it is realized by reducing the abrasive particle size, tool diameter and ultrasonic amplitude. Micro ultrasonic machining has its own advantages. Compared with the traditional processing technology, ultrasonic machining has no great requirements on the conductivity and thermal physical effect of materials, and can process three-dimensional shape, which determines the particularity of micro ultrasonic machining in the processing of non-metallic materials.
4. NC Ultrasonic Machining
CNC is the development trend of mechanical equipment in the future, in our country, manufacturing industry and enterprise processing production, the traditional machine tool still occupies a large proportion, milling machine, grinder, lathe, drilling machine, boring machine, etc., are the corresponding linear motion of the cutter, but slowly these precision can not meet the current demand. The application of ultrasonic technology to CNC machine tools can make the tool get irregular movement mode, which can further improve the machining accuracy.
Ultrasonic machining is now more and more widely used in production and processing, because it overcomes the shortcomings of not easy to be processed, effectively improves the processing accuracy, shortens the processing time, and brings convenience to the production and processing.
