工艺研究院研制成功一种新的阳极-机械磨削法,用来加工大型高强度合金铸铁轴及冷硬铸铁轴,效果显著,比一般磨削法可减小切削力50％以上,降低加工面的粗糙度1～2级,砂轮寿命提高1/3,该法特点是:利用普通砂轮,用3％CaCO_3水溶液作为润滑冷却液,电流密度约1A/cm~2,电源为BKCM-1000标准直流电焊机。阳极-机械磨削法的要点如下:沿零件2整个待加工面长度上有槽形电极1(见图)。为使待加工面与电极之间的液体能自由移动,应留有一定间隙。在磨削加工过程中,电介液浸渍着待加工零件,并充满于零件和电极之间。电介液要经常更新,便于其 Technology Research Institute successfully developed a new anode - mechanical grinding method for processing large high strength alloy cast iron shaft and chilled cast iron shaft, the effect is significant, than the average grinding method can reduce the cutting force of more than 50%, reducing processing Surface roughness of 1 to 2, wheel life increased by 1/3, the law is characterized by: the use of ordinary grinding wheel, with 3% CaCO_3 aqueous solution as a lubricant, current density of about 1A / cm ~ 2, the power supply for the BKCM-1000 standard DC welding machine. The main points of the anodic-mechanical grinding method are as follows: along the entire length of the part 2 to be machined there is a grooved electrode 1 (see picture). In order to make the surface to be processed and the electrode can move freely between the liquid, should leave a certain gap. During the grinding process, the dielectric is impregnated with the part to be machined and filled between the part and the electrode. Dielectric fluid to be updated frequently, to facilitate it
