EDM blanks are tool steel blanks that are provided in the hardened and ground condition. They are available in many popular grades such as: A-11 PM, PM M-4, D-2 and A-2. They provide the toolmaker with a quick and cost-effective way to produce a tooling component.
EDM blanks are tool steel blocks that are machined from quality tool steel into standard size blocks. The blocks are machined to a standard width and length, usually about 5 to 6" wide and 7 to 8" long. They are available in various thicknesses from 1/2" to 4" thick.
These blocks are then hardened and tempered to the standard hardness for each grade. See the chart below:
A-11 PM RC 60-62
PM M-4 RC 60-62
D-2 RC 60-62
A-2 RC 58-60
After heat treatment, the blocks are ground. The blocks are ground oversize to allow for any required finish grinding. These blanks are usually ground to the tolerances indicated in the chart below:
