Graphite electrode production: When the robot takes over the night shift

Italy — Bologna based company Vetimec supplies the international automotive industry and foundries with moulds, including injection moulds. Since die-sinking EDM dominates the production of these moulds, efficiency depends on the production of the graphite electrodes. With the changeover to special milling tools from Hufschmied, Vetimec can now machine graphite 30 percent faster and 20 percent more economically.

Magnetic Filters Cut Down EDM Machine Problems

EDM machines offer precision accuracy, however, the process can be challenging. It is vital that the machine's systems are equally efficient, especially it's fluid management and filter efficiency. This is where magnetic filters come in as it is capable of filtering fine-particles and micron-sized particles from dielectric fluids in EDM machines which makes sure that the fluid is clean and protected from contamination.

Modular machine design ensures high-precision and dynamic operations

The new Maxxturn 65 G2 from Emco has undergone an extensive redesign and, in addition to two powerful motor spindles, now also offers an optional BMT turret with direct drive. For the first time, three spindle sizes can be offered. A steady rest is available for shaft machining if required. While the proven two-part basic design has been retained, the integration of the chip conveyor has been optimised.
