The copper-finishing process uses the MDC polish master machine for optimal quality copper surface balance to minimize tolerance and achieve evenness of the cylinders. The machine is a high precision machining and measuring center for rotogravure cylinders.


A high precision digitally controlled MDC Daetwyler “Polish master machine” with an accuracy of 10 microns per meter is used to achieve accurate and mirror surface that is required for electronic engraving on the cylinder.
