摘要
以直径0.25mm的琴钢丝为基体,粒径22～38μm的金刚石微粉(表面镀膜)为磨料,瓦特镀液为基础镀液,用微型气泵对上砂镀液进行搅拌,用落砂法上砂工艺制造金刚石线锯.结果表明:当气泵电机转速在100～120r/min之间,线锯走动速度为100mm/min,阴极电流密度调节至2～3A/dm2时,可以制得微粉密度稳定的线锯,其微粉密度为1.35Ct/dm2左右.
The 0.25 mm piano wire is used as matrix,coating diamond powder between 22 and 38 μm is chosen as abrasive in this paper.Watt-type solution and sand-falling-electroplated are used to produce electroplated diamond wire saw with pneumatic mixing.The test shows that,the stable diamond powder density of wire saw can be made when the speed of air pump motor is 100～120 r/min and the speed of wire moving is 100mm/min,at the same time,the current density must be 2～3 A/dm2.
