3）特种加工技术。随着社会发展的需要，很多机械设备都有高温、高压、高速和高精度的要求，因而不断产用了一些新材料来制造零件，如淬火钢、耐热合金、硬质合金、硅、锗、宝石和金刚石等难加工材料。同时很多零件的形状也越来越复杂，如小孔、深孔、型孔、窄缝、弯孔和型腔等。用通常的金属切削加工方法来加工这些零件已十分困难，有的就无法加工。这就需要探索新的加工工艺方法；特种加工技术是一种直接利用电能、热能、光能、化学能、声能、电化学能来进行加工的方法。它可以加工高强度、高硬度、高脆性、耐高温等难切削材料，以及精密细小和复杂形状的零件。

3) special processing technology. With the needs of social development, a lot of machinery and equipment has a high temperature, high pressure, high-speed and high-precision requirements, and thus continue production with some new material to manufacture parts, such as hardened steel, heat-resistant alloys, tungsten carbide, silicon, germanium difficult to machine materials, precious stones and diamond. While many parts of the shape is also more complex, such as holes, deep-hole-type holes, narrow, curved hole and cavity. Usually metal cutting machining these parts is very difficult, and some can not be processed. This need to explore new processing methods; special processing technology is a direct use of electricity, heat, light,Chemical energy, sound energy, electrochemical energy to carry out the method of processing. It can be processed high strength, high hardness, high brittleness, high temperature and other hard-to-cut materials, and precision small parts and complex shapes.

3) the special processing technology. With the development of the society, a lot of machinery and equipment have high temperature, high pressure, high speed and high precision, so it has used some new material to manufacture parts, such as quenched steel, heat-resistant alloy, hard alloy, silicon, germanium, ruby and diamond hard machining materials. At the same time, many parts of the shape is more complex, such as holes, hole, hole, narrow, curved hole and cavity. Metal cutting method is usually to machining the parts have been difficult, some cannot be processed. So we need to explore new processing technique; the special processing technology is a direct use of electricity, heat, light,Methods for chemical energy, sound energy, chemical energy to processing. It can process the high strength, high hardness, high brittleness, high temperature resistant, difficult-to-cut materials, and precise and tiny and complex shape parts.

3) special processing techniques. With the needs of social development, lots of machinery and equipment have high temperature, high pressure, high speed and high accuracy requirements, thus continually producing new materials to manufacture parts, such as hardened steel, high temperature alloy and cemented carbide, Silicon, germanium, hard machining materials such as gemstones and diamonds. At the same time many parts of the shape and complexity, such as deep-holes, small holes, hole, narrow, curved holes and cavities. General metal-cutting machining method to process these parts are very difficult, and some will not be processed. This requires exploring new methods of processing; special machining technology is a direct use of electricity, heat, light,Chemical energy, sound energy, electrochemical methods for processing. It can process brittleness, high temperature resistance of high strength, high hardness, high hard cutting material, as well as precision small parts and complex shapes.
