Graphite Wear Testing
September 1, 2014
Ohio Carbon Blank will be performing EDM graphite wear testing with Sodick's AD35L sinker machine using its advanced SVC Circuit + No Arc Machining.
"In today's connected world, purchasing expectations include details to make more informed decisions based upon product research, real data and reviews," said a company spokesperson. "Ohio Carbon Blank believes comparative graphite data (wear testing, removal rates and other data) should be easily accessible. Test 6 is the beginning of its reference database that can be used for comparison of all grades of EDM graphite."
"EDM graphite comparison data is long overdue," said Ohio Carbon Blank General Manager Dale McCartney. "It is our job to provide graphite users with both technical and test data for their purchases."
Ohio Carbon Blank's testing will consist of "burning" sharp corner slotted shapes into hardened H-13 tool steel using six different graphite grades. Rougher and finisher electrodes will be used to replicate the EDM of die or mold tooling applications.
Sodick's AD35L Sinker with Linear Motor Drive System and the Test 6 results will be showcased at the booth. Comparative illustrations and photos of electrode wear rates, surface finishes and cutting times will be featured. The first six graphite materials to be tested will include:
- Medium density graphite grades (AR-12, EDM-200)
- High-density graphite grades (AR-14, TTK-4, DS-4, EDM-3).
