Electric-discharge machining is a reproducing forming process, which uses the material removing effect of short, successive electric discharges in a dielectric fluid. […]
modern tooling machines for mold making generally feature multiaxial CNC controls and highly accurate positioning systems. the result is higher accuracy and greater efficiency against rejects. […]
Increasing the effectiveness of EDM operations does not come solely with technological improvements in the EDM sinker. This is one of many aspects needing to be considered when working to optimize EDM performance and increase productivity. Other areas of consideration include the type of dielectric fluid, tooling and electrode material used in the EDM applications. [...]
For years we have been hearing about the virtues of aluminum molds for injection parts, and First-rate mold company’s Mold Builders has built its fair share—mostly for special-purpose applications that did not require many actions. For smaller molds using specialty aluminum has its benefits; and, if cycle times are critical, you can justify the high [...]
We all know that EDM setup can be extremely time-consuming. Automating the setup process can save valuable time, especially when considering that some tools (especially those with multiple cavities) require dozens or even hundreds of electrodes. […]
There are numerous factors to consider when purchasing a warranty program with your new EDM, let’s examine three important ones. […]
Die sinking EDM works wonders in cutting contours or cavities in pre-hardened steel. When dealing with complex shapes, however, milling the electrodes that produce these intricate pieces can be a quite involved and time-consuming process, so manufacturers want to extend electrode life as much as possible. […]
First and foremost, machine selection is a huge part of operational efficiency in EDM. Depending on the application, moldmakers can choose from wire, drilling, sinker or some combination of the three. […]
A number of recent EDM developments offer significant solutions to obstacles facing the moldmaking industry in the millennium. […]
While much has changed in die sinking technology, one of the foremost advancements is the development and continual improvement of adaptive control, or fuzzy logic, to eliminate the guesswork and allow the machine to take control of the metal erosion process. […]
