铝镍铜钴型磁性合金由于硬度高、脆性大,通常很难用带刃的切削工具进行加工。尤其是在35T5AA(洛氏硬度HRC54)合金制的单晶磁铁上打孔,一般都是在电腐蚀加工机床或电化学加工机床上进行的。但是电腐蚀加工方法的生产率不够高(约25—30立方厘米/分),组织变化层深达0.2毫米。打孔速度也不高(0.5—0.8毫米/分)。此外,工具——电极强烈磨损。
Aluminum-nickel-copper-cobalt magnetic alloy due to high hardness, high brittleness, usually difficult to use cutting tool with a blade processing. Especially in the 35T5AA (Rockwell hardness HRC54) alloy single-crystal magnets on the punch, are generally in the electric erosion processing machine or electrochemical processing machine carried out. However, the productivity of the electroerosion method is not high enough (about 25-30 cc / min) and the depth of the microstructure changes to 0.2 mm. Punch speed is not high (0.5-0.8 mm / min). In addition, the tool - the electrode is strongly worn.
