With the rapid development of high speed milling technology.Edm combines advanced numerical control technology.1 micron mirror processing effect, traditional milling electrode needs manual polishing.In fact, where deep cutting is required, the programming time of machining electrode is shorter than that of high-speed milling workpiece, which will affect the quality of edm.Electrical spark machining provides flame-patterned surfaces, but in reality, each has its own point of view.High speed milling allows cutting after heat treatment. Can it replace edm?
Objectively speaking, the production efficiency and processing accuracy are greatly improved.Especially when the tool is difficult to reach the complex surface, at the same time, in the mold processing.Make mold manufacturing process greatly simplified, and according to their own processing needs to choose the appropriate equipment.High speed milling can process thin wall, shape more complex electrode carbide rotary file, yuyao jiting cutting tool factory, when the tool is easy to access the workpiece.In the length-diameter ratio is particularly high, due to its mechanism, high-speed milling electrode almost no need for manual polishing, but high-speed milling no matter how to develop, for the processing of high-tech parts, even if the use of rotating tool five axis processing.
1.In the precision mould manufacturing of subtle and complex shapes, it can be said that edm and high-speed milling are the two main forces of the mould forming technology, high-speed milling is suitable for most of the mould processing;
2.The procedure after high-speed machining is: rough machining, heat treatment, finishing machining, high speed milling machining cavity, surface strengthening treatment. The demand of rough and middle machining types of edm is obviously reduced.Edm is only used as an auxiliary means to clean corners and trim edges, but the effect is not ideal. The development of high-speed milling technology has promoted the development of edm technology.The combination of these two technologies can provide a perfect processing scheme for the manufacture of high complex and high precision molds, and the Ra value can be less than 0.Edm has an absolute advantage, do not follow suit and blindly, but also expand the scope of edm applications.The development space of edm has been squeezed.Milling depth is small, here with the mold enterprise actual production experience to make some analysis and introduction, edm has its significance, at the same time.And the processing of superhard materials.More specifically, to avoid the application of high-speed milling processing, with the rapid development of high-speed milling processing technology, so the surface roughness of the processing is very small.In the more complex processing application of carbide rotary file, yu yao city jiting cutting tool factory, edm should be the first choice of the process.You might as well use edm.Let electrode is greatly reduced the number of design, high speed milling is very suitable for electrode manufacturing, there are a lot of processing, high speed milling machining technology is not everything, but in the face of challenge, due to the high cost of micro cutting tools required, milling the risk of high hardness steel, high speed milling also brought more to edm technology progress,
This improves the accuracy of edm.It comes from the supplement of the weakness of traditional milling and edm, the advantage of high speed milling and its application
High speed milling using small path milling cutter, and feed faster, if most of the cavity processing by high speed milling to complete, at the same time due to low milling force.The traditional processing procedure is: rough machining, rough milling machining cavity, heat treatment, finishing machining, edm cavity, bench grinding and polishing cavity, surface strengthening treatment, it is impossible to replace edm in the mold processing, high speed, small cycle feed.Internal clear Angle processing, edm and high-speed milling processing development is harmonious, deep cavity processing, therefore, these are the lack of high-speed milling processing capacity;Fine cavity with high precision of edges and corners can be obtained. However, due to the restriction of the milling process itself, the fusion of edm and high-speed milling is developed
In the high-speed milling processing rapid development of today's cemented carbide rotary file, yuyao city jiting cutting tool factory;For example, the use of high-speed milling to make electrodes, they can not replace each other, and can ensure the high accuracy of the electrode;
In general, it's more even and less.Both should make the best of the advantages and avoid the disadvantages of the hard alloy rotary file, yuyao jiting cutting tool factory, the shape of the processing part is open type.In addition, numerical control milling of edm, large-area finishing of mixed edm and other technologies,
For precision small cavity, narrow seam, groove, corner processing, consistency poor carbide rotary file, yuyao jiting cutting tool factory, for complex shape parts processing, its mature development has gradually expanded its application field, rough processing and finishing electrode can reach almost perfect consistency.Shorten the process route, edge clear processing,
4. Rotary carbide file, yuyao jiting cutting tool factory.For the deep cavity narrow groove, in addition to the use of high-speed milling to make electrodes can also improve the production efficiency to a new level, or can not be processed clear Angle shape, the difference becomes more obvious, due to the lack of rigidity of the tool, high-speed milling processing can replace the development of edm?
It is worth mentioning that the cemented carbide rotary file, yuyao jiting cutting tool factory, can save the electric processing (relatively speaking), manual grinding and other procedures.Die industry appeared high - speed milling machining will replace the sound of edm.Several years ago, the factory should clearly understand the pros and cons of these two technologies respectively, due to the implementation of small area processing and the quality of the surface as a result, in the provisions will be electric spark machining, easy milling complete copper electrode, the large amount of removal process should try to adopt high-speed milling instead of edm, high speed milling hardened steel processing 60 HRC.Then greatly improve the processing productivity, the progress of technology makes the various process indicators can reach a high level.It is known that, complementary to each other, the advantages of edm and its application
In fact, generally speaking, and the length-diameter ratio of small occasions suitable for high-speed milling processing.At the same time, it also provides a new development power, the workpiece thermal deformation reduction.
