Auto EDM Wire Changers Compete at the High End

Automatic EDM wire-change capability can improve efficiency and reduce costs for high-end tool and die work, especially parts with small internal radii.

Improved Break-Out Detection for Small-Hole EDM

The Current EDM RT6050 features software and hardware upgrades that improve the ability to detect when the electrode breaks out of the bottom of a hole.

A Big-Picture View of Micromachining

 Matrix Tooling makes injection molds for components that have features you cannot see.

Wire EDM with a Twist

Wire EDM units that swivel a horizontally guided electrode wire in a CNC-controlled E axis give this shop the workpiece clearance and flexibility to produce complex, high-precision PCD-tipped cutting tools.

Spark Control Pushes Wire EDM Boundaries

Precisely controlling and monitoring each individual spark enables this wire EDM machine to cut hardened, high-temperature alloys with high precision.

Special High-Temp Alloys Spark Interest in EDM

Today’s wire EDM technology preserves the surface integrity of proprietary titanium alloys and other high-temperature materials, so aerospace and medical applications using this process are booming.

Wire Rethreader Hits The Mark

The rethreading system on a wire electrical discharge machine helps a U.S. manufacturer keep up with production requirements for a critical pistol component.

EDM Energy Conservation Without the Effort

Most machine tool energy conservation systems simply track power consumption, placing the burden of actually reducing energy use on manufacturers. GF AgieCharmilles aims to change that with the EconoWatt II, an automated system for wire EDM.

What Shapes a Shop

Marshall Manufacturing melds CNC machining and 3D bending to create intricate medical components from small-diameter barstock and tubing. Customer needs spurred the shop to carve out what has become a successful medical-manufacturing niche.

Tips for Controlling Oxidation and Pitting on a Wire EDM

Additives, machine settings, workpiece materials and current technology are factors in avoiding common problems with unwanted rust and surface defects.
