EDM Machining, while simple in operation, poses risks to safety of the Operator. It is therefore important to understand the importance of certain maintenance activities, essential for safe and efficient operation of the EDMs. Operators have to be alert and aware of the following points. Electrical Shocks Make the Operator aware about hazards of even … Read more
Manufacturing medical devices includes a diverse range. Starting from hip joints or replacement devices to simple tools such as tongue depressors, bedpans to critical components in pacemaker, orthopaedic inserts to advanced and other surgical devices. Range of Materials Implantable devices like screws and replacement joints, as well as orthodontic braces and other dental pieces, are … Read more
Precision is the holy grail of Aerospace industry. The stringent quality norms, and moreover its regulatory norms means aerospace component manufacturers have to always put in an extra bit of efforts to ensure they meet all precision requirements. Scale of precision manufacturing is another aspect that aerospace companies have to keep a tight watch on. … Read more
Surface finish in very important aspects when it comes moulds in particular, as product coming out from mould is typically a mirror image of mould itself. If the mould has any particular ‘lays’ it will directly have opposite impression on product. An EDM surface finish is different to that produced by conventional machining. Cutting processes … Read more
EDM or Electrical Discharge Machine uses thermal erosion to remove small bits of conductive metal using repeated electrical discharges between the cutting tool, which functions as the electrode, and the piece itself in the presence of a dielectric fluid. Here a high frequency electrical discharge occurs in the gap between the cutting tool and the … Read more
When it comes time to decide whether to use graphite or copper electrodes in your shop, it’s important to look at the big picture. One has to consider application for which EDM is going to be used, depending on which a type of electrode can be chosen. Earlier, Copper was the only option available, however … Read more
EDM Drills can be technically classified as a specialized EDM machining process, where a small hollow electrode, spinning around the spindle is used to drill small holes. The electrode is electrically charged using a servo-controlled generator and produces a spark. Water is commonly used as a dielectric. The dielectric flows through the electrode under pressure … Read more
In order to lower manufacturing cost, Japanese and Swiss EDM builders moved their plants to countries with lower labor cost. Seibu decided against this trend because it was against their philosophy. Seibu manufacturing philosophy is about quality and not quantity. Only 30 to 40 individually created high quality Seibu machines are hand crafted per month … Read more
Installing an EDM is different from acquiring a VMC, HMC or CNC lathe. The EDM Operation has some special requirements. Of course, these requirements are not complex or expensive but they are surely Important. Neglecting those can surely have a significant impact on the installation of the machine. After you have purchased an EDM, installation … Read more
As EDM industry is growing year-on-year, and steadily the outlook towards it has changed during this period. Market looks at EDM as proven and precise machine, which can do wonders as compared to conventional machining. While there are many methods used to come to conclusion as to what material is to be used, we at … Read more
