I believe that everyone is no stranger to precision parts processing, in general, to judge the quality and precision of a product is only to see whether it meets the requirements. Then, wire cutting plays a role in the perfection of precision, +/-0.005mm for it is a small case!
If you don't know, you may take it literally and understand that wire cutting is not the use of wire to cut products? Yes, it is true that it uses wire to cut products, but this "wire" is not ordinary wire! It is called electrode wire, which needs to have good electrical conductivity and resistance to electrical corrosion, high tensile strength, and the material should be proportional. Often used electrode wire has molybdenum wire, tungsten wire, brass wire and cored wire and so on.
Wire cutting: slow walking wire processing machine tungsten wire high tensile strength, relatively expensive, generally used in many narrow seam finishing. Brass wire is suitable for slow processing, processing surface roughness and straightness is better, less etching chip attachment, but poor tensile strength, high loss, in the slow one-way wire processing is widely used. Molybdenum wire high tensile strength, mainly used in fast wire processing, general China's machinery processing enterprises are mostly selected for the electrode wire molybdenum wire.
Wire-cutting: There are three types of wire-cutting in slow-walking processing, and the precision of different types varies, respectively: fast-walking, medium-walking and slow-walking; generally the precision of fast-walking can reach +/-0.02mm, and the surface roughness can reach Ra3.2 ;the precision of medium-walking can reach +-/-0.01mm, and the surface roughness can reach ≤ Ra3.2; the precision of slow-walking can reach +/- 0.005mm, surface roughness can reach Ra0.8, therefore, the slow walking wire in the precision and quality are higher than the other two. Wire-cutting is developed on the basis of EDM piercing and forming processing. It not only makes the application of EDM has been developed, and some aspects have replaced the EDM piercing, forming processing. Today, wire EDM machine tools have accounted for the majority of EDM machines, playing a large role in the processing of precision parts, increasingly popular in today's market.
