Mirror Finish Machining for Narrow Grooves and Cavities
Narrow grooves and small cavities create challenges in tool access, rigidity and finishing. This article explains how precision milling and mirror EDM can work together to achieve stable mirror surfaces and accurate geometry.
Right-Angle Mirror Cavities: CNC or Mirror EDM?
Right-angle mold inserts require careful process selection to maintain corner accuracy, surface quality and geometry consistency. This article explains when CNC mirror machining or mirror EDM is more suitable for precision cavities.
Reducing Mold Insert Rework: Stop the Cycle Before It Starts
Repeated machining, EDM and polishing can quickly turn a small defect into an expensive rework cycle. This article explains how better process planning, controlled finishing and intermediate inspection help reduce mold insert rework.
Small Radius Mold Insert Machining: Protecting Corners Before Polishing
Small radii and sharp internal corners can easily change during polishing. This article explains how machining strategy, tool selection, mirror EDM and controlled finishing help protect critical corner geometry.
