Mr Lu Xiaohui: EDM processes domain application in the mould very extensive, it is a of mould manufacturing industry vital treatment technology, the mould that can realize all sorts of pair of material is machined. In a few years of in the past, as the occurrence of a lot of new material, the craft of EDM also produced very big change, total finished cost rises subsequently, with having before very big different. But the occurrence as high speed mill, treatment of a few EDM is replaced, somebody fears high speed mill can replace EDM completely at that time, look now this kind of concern is redundant. After all two kinds of equipment have its actor drawback each in mould treatment domain. Machine the part with larger deepness for example, need bigger cutting tool to grow diameter comparing, the deepness that somebody thinks cutting is machined depends on the mastery of a skill or technique that handles personnel and use machine, of course its deepness and machine performance are relative, because of machine tool of common high speed mill, the long way of its cutting tool compares treatment work amount to 4 ～ 5 times; And fall in similar case, although can achieve 8 ～ ,the long way of its cutting tool compares machine tool of high speed mill 10 times, but this already also arrived the treatment limit of high speed mill. And EDM has very good solution however to this. And though high speed mill machines speed fast, but also be not all pair of moulds to make an user applicable, handle finished cost of the level of personnel, whole after all, and the requirement is relatively complex wait for a characteristic, it is normal to affected high speed mill the play of efficiency. The client is met the characteristic according to the product, undertake different collocation to these two kinds of equipment. We can have specific aim ground to offer a solution for the client, assist them to solve a problem. As to the development trend of EDM and high speed mill, herd tough firm devotes oneself to the research of this respect and effort all the time. Make equipment stabler to high speed mill, especially the thermal stability in treatment of high speed high accuracy becomes particularly important. In addition, high speed treatment matchs to the intensity of main shaft, bearing and whole, even the space that cutting fluid temperature has promotion. To EDM, how does the biggest challenge raise treatment rate namely. Mu Ye is newest research and development SSGR technology, can make machine speed to raise 30% ～ 40% . In the meantime, its machine precision to be able to be achieved 0. 001 μ M. This to EDM character is a major milestone undoubtedly. In addition, it is the exterior surface roughness of treatment, especially the lens face treatment of large area. Can so say, what what we do today is the issue that we consider not to have the courage to think 5 years ago, after all the development of market guiding technology and progress. Our target not only should offer best product for the client, first-class service, and should assist a client to reduce production to make cost. CNC Milling
