摘要：分析了树脂金刚石线的制造工艺过程，针对金刚石线的树脂层半固化和固化过程中，因溶剂挥发和树脂固化而造成的体积收缩问题，提出了树脂层中金刚石浓度及其添加量的计算方法，得到了在已知树脂浆料中金刚石磨料的添加量时，固化后树脂金刚石线树脂层中金刚石浓度的计算方法，以及要获得一定树脂层金刚石浓度时，树脂浆料中金刚石磨料添加量的计算公式。该方法可对树脂金刚石线中金刚石微粉的量化设计、树脂金刚石线生产工艺的优化设计等提供参考。

Abstract:The manufacturing process of resin diamond wire is analyzed.The calculation method of diamond concentration and diamond addition amount in the resin layer is studied for the problem of volume shrinkage caused by solvent evaporation and resin solidification during semicuring and curing of the resin layer applied to the resin diamond wire.Accounting for the volume shrinkage problem in the manufacturing process of the resin diamond wire，the calculation formula of the diamond concentration in the resin layer after curing is derived when the amount of the diamond abrasive added in the resin slurry is known.And a formula for calculating the amount of diamond abrasive added in the resin slurry is obtained accounting for a certain concentration of diamond in the resin layer.The research has certain reference significance for the quantitative design of diamond powder in resin diamond wire and the optimization design of resin diamond wire production process.
