Why EDM graphite mold works?

Really, both choices are excellent, and your unique application and equipment will determine which is best for your needs. Investing in quality EDM supplies only makes sense. Industrial supplies play a key role in mold making, skimping on quality only hurts in the end.

Graphite is by far the most common electrode material used in the United States. EDM technology has advanced so that all new machines have circuitry that adapts to either graphite or copper. Graphite has many outstanding characteristics, here is a partial list:

  • No need to redress grinding wheels; the details remain sharp almost indefinitely.

  • Ability to achieve fine finishes

  • Low wear

  • Very good for roughing operations, less expensive grades can be used

Grades of graphite
There are four primary grades of graphite used in EDM machining .

  • Angstrofine- Less than 1 micron particle size. This is used when an extremely fine finish is required.

  • Ultrafine- Less than 5 micron particle size. Most finishing electrodes are of this type.

  • Superfine- 6-10 micron particle size. This type is generally used for roughing in cavities with larger details.

  • Fine- 11-20 micron particle size. Used for roughing in large cavities

Cost of graphite
Choosing the correct grade of EDM graphite for the job can mean substantial cost savings. For example: using an Ultafine grade for roughing a large cavity is wasting money. A lesser grade of graphite will actually outperform a fine grade in such a case.

Conversely, using a Fine grade instead of an Ultrafine grade to machine fine details will not only waste money, but not produce the desired results.

Good electrode material choices and correct EDM machining parameters can greatly affect the bottom line. It is important as well, to have an organized system of storing your graphite, so precious time is not wasted on using the wrong type by mistake.
