Roughing of graphite electrodes can be done by using inserts, if the electrode is large enough, or shank tools, if it is small. For electrode size 50x50 mm or above, we recommend using diamond coated round inserts RDHX0501 or RDHX0802 with a 13 mm cutting diameter and 12 mm shank diameter tool holder. Fig. 4 Fig. 4 shows an example of this tool.

DRAMET diamond wire grinding machines saw graphite electrodes into contours as well as 2D and 3D shapes. Graphite electrodes are usually 30-100 mm high and require complex contours to be machined. The difficulty often lies in the fact that only thin, widely projecting tools can be used for machining. A wire is the perfect tool for this, as it ...

Abstract. In this paper, the tool deflection is first analyzed analytically, based on a four-section cantilever beam representation of the tool. Contributions of different sections of the tool to total tool displacement are quantified. Then the influence of cutting parameters (width of cut, depth of cut, and feed per tooth) on tool deflection ...

Milling of 2-D and 3-D graphite electrodes has grown tremendously over the last several years. Standard tooling for our mills was exclusively carbide. High speed and cobalt tools were used only when a diameter, length, or special cutter shape make the cost of carbide prohibitive. To increase capabilities for tolerance and challenging inspection ...

The numerous advantages mean that graphite electrodes are indispensable in spark erosion – no manual work, no deburring, hardly any burning, even intricate geometries are possible and the electrode comes out of the milling machine ready to use for erosion. However, as before, graphite dust is the spectre that haunts production.

Therefore, compositing Tin/Tin oxides with stable graphene via ball milling is a promising strategy to overcome the intrinsic limitations of Tin-based electrodes. Wang et al. verified that the graphite and tin composite electrodes have better stability than the pristine graphite electrode via ball milling . The authors fabricated graphite and ...
