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.


What is the Best Process for Machining a Small, Precise Hole in Aluminum?

This small hole is actually large enough that any of three different processes might be used.


The Most Valuable Resource For Succeeding At Lean

What is the most valuable resource? The answer is probably obvious: the people. This shop started to succeed at lean manufacturing once every employee got involved.


Vision System Brings On-Machine Measurement To Ram EDM

Vision technology tailored to ram EDM allows shops to measure a part as it remains fixtured on a spark-erosion machine.


Micropulse Technology Comes To Fast-Hole EDM

Holes in turbine blades are critical because the internal cooling airflow provided by these holes prevents the parts from overheating during operation. One of the most promising technologies for making these holes is fast-hole electrical discharge m...
