Why Are CNC Tool Marks Still Visible After Mirror Machining?

Deep CNC tool marks can turn a finishing job into repeated polishing and rework. We explain how tool stability, spindle speed, tool path and five-axis machining can improve the starting surface.
Mirror Mold Insert Dimensions Changed After Polishing?

Mirror polishing can improve a mold insert’s surface while quietly changing small radii, edges or critical dimensions. This article explains where that risk comes from, how we reduce the finishing burden during machining, and why critical geometry should be checked again after polishing.
