metallic bond

Two types of metallic bond , conjugated σ bond and conjugated π bond , harve been treated by LCBO MO method .

用LCBOMO法统一地处理了金属键的两个类型：共轭σ键和共轭π键。

So it has great applied value to research metallic bond diamond wheel .

所以，研究金属结合剂金刚石成形砂轮的精密修整技术具有重要的应用价值。

The metallic bond diamond wheel can process hard brittle material of complex surface , it can be high efficiency , precision and large-tonnage scale .

使用金属结合剂金刚石成形砂轮可实现复杂型面硬脆材料的精密、高效、量产化加工。

Electric spark dressing can achieve high dressing precision , and it is very convenient to operate , also has zero dressing force . The trimming and shaping process are managed side-by-side , so it is an ideal method to dress metallic bond form-grinding wheel of ultra-hard abrasive .

电火花修整具有修整精度高，操作方便，无修整力等优点，且整形与修锐同时进行，是修整金属基超硬磨料成形砂轮的理想方法。
