How To Use Roll Dimensions For Measuring And Inspection

Here is a method to figure out the roll dimension manually. Obviously, it is easier if you use a computer to draw and measure the distance. Many times, however, you cannot use a computer, don’t know how, or just don’t want to rely on a CAD program. This method takes a while to get used […]

Choose The Right Carbide Cutter For EDM Electrodes

With the advent of high speed machining for EDM electrode manufacture, the tooling has become even more important. Graphite, in particular, is notoriously hard on end mills, creating headaches for both programmer and operator. Various companies have invested heavily in research and development to meet this demand. Three developments are changing the way carbide cutters […]

Automatic Tool Changers Are Changing

The integration of the WEDM, sinker EDM and the various electrode manufacturing machine tools takes a great deal of planning and forethought, but the end results can be quite profitable. This is not the time for short-term thinking, as automated tool making requires considerable commitment of time, money and materials. Time spent preparing, studying, consulting, […]

EDM Meets High Speed Milling

This is a much different approach than that of the past. In the “old days” the electrodes were made by the toolmakers on surface grinding machines, manual milling machines, usually involving a lot of hand work as well. The days of a mold shop having a few Bridgeport milling machines, some Harig grinders and several […]

EDM Meets Micro Welding

Most mold and die repair involves using a laser welder or a micro welder. Once it is welded, the mold needs to be re-machined, or hand-worked back to it’s original state. This is where the EDM comes in, often as the only practical method or remachining the hardened steel. The laser welder is a marvel […]

4 Tips For EDM Jobs

In the US, there are really not many schools that offer any training specifically for electrical discharge machining. It is usually a part of an overall tool and die course, along with blueprint reading, CAD/CAM programming, surface grinding, CNC milling machine operation and lathe work. Some of the traits that are advantageous to work in […]

7 Sides Of EDM Supplies

Without the proper supplies, such as dielectric fluid, electrode holders, machine vises, electrode materials, Erowa or System 3R precision tooling, EDM filters, dielectric fluid, and a well equipped inspection area, the investment will fall short of your expectations. It might seem hard to imagine that anybody would spend a great deal of money on a […]

How To Choose Precision EDM Tooling

The modern EDM department must be equipped with high quality inspection and set-up tooling. It makes no sense whatsoever to invest in a high end machine tool, such as a Charmilles-Agie Robofil wire EDM machine and skimp on the supporting tools. The modern EDM department must be equipped with high quality inspection and set-up tooling. […]

4 Things To Know About Automated EDM For Mold Making

With an automatic tool changer, pallet changer, precision EDM tooling, CMM, and a lot of planning, it is quite possible to run the department 24/7. By integrating these various tools in the manufacturing process, the mould maker or tool-and-die-maker can have complete control. This greatly helps with producing precision mold components and die components in […]

What Is EDM, Or Electrical Discharge Machining?

The plastic injection mold making and die making industries rely heavily on EDM machining, both with the sinker EDM and wire cut EDM machine. The electrical discharge machine is a totally amazing and somewhat mysterious tool, without which, our modern way of life would be much different. As far as I can gather, two Russian […]
