EDM Blanks Pre-Machined, Pre-Hardened

Saturday, June 1, 2013

Diehl Steel, Cincinnati, OH, has introduced Ready-Block EDM blanks for EDM applications. The ready-to-use blanks are pre-hardened, squared and ground inhouse, eliminating the need for customers to machine and heattreat them prior to use.

The blanks come in several tool-steel grades including A2 and D2. Each block is precision machined to a specific thickness, width and length, within +0.010-in./0.020-in. tolerance. They then are hardened and tempered to a standard hardness; a starter hole is included at the customer’s request.
