一、高频电源的改进我们厂的一台线切割机床过去只能切割10毫米以下的工件,切割下来的工件就象锉出来一样,谈不上“光洁度”三个字,稍厚一点的工件,一上去就断丝。后来请兄弟厂的师傅重新搞了一台高频电源。搞好以后,虽然能够切割,但对厚工件,特别是硬质合金,仍要断丝。即使不断丝,加工也是很不稳定。于是我们首先从脉冲的搭配上作了一点调整。原来脉冲周期和脉 First, the improvement of high-frequency power supply Our factory a wire-cutting machine in the past only cut the workpiece 10 mm below the workpiece cut like a rasp out the same, not to mention “finish” three words, a little thicker workpiece On a broken wire. Later, please brother factory master re-engage in a high-frequency power supply. Do a good job, although able to cut, but the thick parts, especially cemented carbide, still broken wire. Even if it is not continuous, processing is very unstable. So we first made a little adjustment from the pulse collocation. The original pulse cycle and pulse
