Description

ленне значительно ниже примен емого в насто щее врем (200 кгс/см), что существенно повыщает стойкость пресс-форм и позвол ет при том же усилии прессовани соответственно увеличить площадь ирессуемых электродов .Lening is much lower than currently used (200 kgf / cm), which significantly increases the durability of the molds and allows, with the same pressing force, respectively, to increase the area of the pressed electrodes.
Таким образом, изобретение позволит повысить производительность эрозионной обработки в 1,5-2 раза при уменьщении износа в 1,5-3 раза, снизить трудоемкость изготовлени и себестоимость электродов-инструментов.Thus, the invention will make it possible to increase the productivity of erosion treatment by 1.5–2 times while reducing wear by 1.5–3 times, to reduce the laboriousness of manufacturing and the cost of tool electrodes.
