Increasing the Efficiency of Finishing of Quartz Crystal Elements through Controlling the Structural, Mechanical, and Rheological Characteristics of Abrasive Suspensions

Abstract

One option for solving the scientific and applied problem of increasing the efficiency of finishing quartz crystal elements (QCEs) through controlling the structural, mechanical, and rheological characteristics of abrasive suspensions is presented. The finishing technology for manufacturing QCEs is flat finishing on machines using an abrasive suspension of fine Al₂O₃ particles. The dispersion medium in the abrasive suspension during finishing of QCEs ensures uniform distribution of abrasive grains over the lap, minimizes the sticking of separating quartz particles, and facilitates its dispersion. Control of the structural and mechanical characteristics of the abrasive suspension is achieved by introducing into the dispersion medium (water) stabilizers such as protective colloids, which prevent the approach of abrasive particles and the destruction of quartz. The problem of QCE finishing has been solved by the authors for the first time ever.
