超声波抛光机经国内一些单位使用验证,适用于中、小模具加工、特别用作电火花加工的后续工序,有较好的工艺效果。现将其使用简介如下。 (一)中、小型冷冲模刃口线切割后的拋光:众所周知,基于电加工机理,线切割后的刃口表面会出现厚0.02mm左右的软化层,且国内切割光洁度普遍仅达▽5～▽6,并伴有明显走丝条纹。这些缺陷严重限制了模具寿命的提高。若采用手工抛光,对于形状复杂的刃口,会因余量不易掌握而破坏
Ultrasonic polishing machine validated by some domestic units, suitable for medium and small molds, especially for the follow-up EDM process, a better process results. Now the use of briefings are as follows. (A), the small and medium-sized cold die edge polishing after cutting: As we all know, based on the electrical processing mechanism, after the wire cutting edge surface thickness of about 0.02mm will appear softened, and the domestic cutting finish generally only ▽ 5 ~ ▽ 6, accompanied by a clear trace of walking thread. These defects severely limit the improvement of mold life. If using manual polishing, for the complex shape of the edge, due to the remaining volume is not easy to grasp and destroyed
