该种产品是哈尔滨电碳研究所采用新工艺研制成功的一种新型的电火花加工用石墨。 由于它比一般电加工石墨具有更好的抗热冲击性、耐高温、耐腐蚀、热膨胀系数低、内应力小,容易加工、抗电弧性能好、加工效率比铜高、损耗率低、被加工的部件精度高和表面光洁度好等特点,所以近年来被广泛地应用在形状复杂的型腔模和其它硬质合金的加工制造方面。
This kind of product is a new type of EDM graphite which is successfully developed by Harbin Institute of Carbon Research using new technology. Because it has better thermal shock resistance than ordinary electrical graphite, high temperature resistance, corrosion resistance, low thermal expansion coefficient, small internal stress, easy processing, arc resistance, processing efficiency than copper, low loss rate, is processed The components of high precision and surface finish and so on, so in recent years has been widely used in the shape of complex cavity mold and other carbide processing and manufacturing.
