The company has integrated its Minifix P-Holder system to 3R and Erowa. Using the base components from each company makes it possible for 3R and Erowa system users to use the holders without the need for expensive adapters, the company says. These holders are said to allow a variety of ways for small to medium sized electrodes to be held accurately. Four X, Y and Z references allow 90-degree indexing of the electrodes. "Rock Solid Referencing" (no moving or bending parts) allows ± 0.0001" on/off accuracy of the electrode. Pre-formed copper blanks that attach directly to the holders are available in a variety of sizes, square or round. Graphite electrodes can also be machined to mount directly to the holders or via the H5.51.11 pallet with the use of the H5.51.111 screw. "Ready to Cut" pallet mounted graphite blanks are also available. The holders are available in two lengths (approximately 2.3" and 5.3") for each tooling system. Part numbers for Erowa users are H5.51.1-ER and H5.51.2-ER and for 3R users H5.51.1-3R and H5.51.2-3R. Clamping spigots/studs are not included.
