1 标准动平衡为G6.3/10000RPM，一般台湾产品为G6.3/8000RPM，动平衡效果更佳。2 全系列动平衡校正，每一ER螺母均经校正（包括侧固式刀柄）。3 刀柄中心出水和法兰出水设计，更适合欧洲机床配备。4 内部抗拉强度为950N/mm2,淬火硬度为HRC60±2，淬硬层深度为0.8mm±2,表面通过发黑和精磨处理。5 采用5轴车铣复合机，一次性加工完成，减少二次以上重复夹持误差。6 耐用性很好，我司刀柄在使用一年后还可以保证同新刀柄同样的精度，台湾其它厂商的刀柄使用半年后基本上不能保证很好的跳动精度。规格如下：SK30-ER16B-70HSK30-ER16B-100HSK30-ER16B-70SK30-ER16B-100SK30-ER20B-70HSK30-ER20B-100HSK30-ER20B-70SK30-ER20B-100SK30-ER25B-70SK30-ER25B-100SK30-ER32B-70SK30-ER32B-100SK30-ER40B-70SK40-ER16C-63HSK40-ER16C-100HSK40-ER16C-160HSK40-ER16C-200HSK40-ER16C-230HSK40-ER16C-63SK40-ER16C-100SK40-ER16C-160SK40-ER16C-200SK40-ER16C-230SK40-ER20C-60HSK40-ER20C-100HSK40-ER20C-160HSK40-ER20C-200HSK40-ER20C-230HSK40-ER20C-60SK40-ER20C-100SK40-ER20C-160SK40-ER20C-200SK40-ER20C-230SK40-ER25C-60SK40-ER25C-100SK40-ER25C-160SK40-ER25C-200SK40-ER25C-230SK40-ER32C-70SK40-ER32C-100SK40-ER32C-160SK40-ER32C-200SK40-ER32C-230SK40-ER40C-80SK40-ER40C-100SK40-ER40C-160SK40-ER40C-200SK50-ER16C-63HSK50-ER16C-100HSK50-ER16C-160HSK50-ER16C-200HSK50-ER16C-250HSK50-ER16C-300HSK50-ER16C-63SK50-ER16C-100SK50-ER16C-160SK50-ER16C-200SK50-ER16C-250SK50-ER16C-300SK50-ER20C-60HSK50-ER20C-100HSK50-ER20C-160HSK50-ER20C-200HSK50-ER20C-250HSK50-ER20C-300HSK50-ER20C-60SK50-ER20C-100SK50-ER20C-160SK50-ER20C-200SK50-ER20C-250SK50-ER20C-300SK50-ER25C-60SK50-ER25C-100SK50-ER25C-160SK50-ER25C-200SK50-ER25C-250SK50-ER25C-300SK50-ER32C-70SK50-ER32C-100SK50-ER32C-160SK50-ER32C-200SK50-ER32C-250SK50-ER32C-300SK50-ER40C-80SK50-ER40C-100SK50-ER40C-160SK50-ER40C-200SK50-ER40C-250SK50-ER40C-300
