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...


A Role For Rotary Erosion

A cutting tool manufacturer uses multitasking equipment that combines electrical-discharge grinding and conventional grinding to speed the production of diamond tools.


Electrical Discharge Saw Slices Through Hard Alloys

Electrical discharge sawing uses spark-erosion technology and is said to create blanks from exotic alloys as much as 70 percent faster than wire EDM.


Room To Grow

This wire EDM job shop in Wisconsin acquired a submerged cutting wire machine that lets it handle larger, taller workpieces than just about any other job shop in the country. The new machine has a “column-up” option that adds a riser block between t...


A Highly Complementary Combo

Wire EDM and abrasive waterjet go together well, especially for cutting aluminum.


How To Handle Tall Wire EDM Work

Modular workpiece fixturing plays a vital role in this shop’s quest to win larger, more difficult wire EDM jobs.


Multitasking Ram EDM

Multitasking capability is coming to EDM. This ram EDM unit can switch from ram to wire EDM to produce holes as small as 0.03 mm in diameter.


Incremental Automation Pays Dividends

While successful mold makers agree that automation is necessary to remain competitive, they often have different opinions about how to integrate automation. This mold maker does it in gradual phases, and in doing so, it drives shopfloor workers to r...


Process Pioneers

There is something different about the molds this shop builds. This puts EDM in a whole new light. These molds are not designed to produce plastic parts, like the typical injection mold. Rather, these molds produce parts in metals such as stainless ...


Flexible Grinding, No Grinder Required

At the heart of this process for lean manufacturing of nickel alloy turbine blades are CNC machining centers equipped with grinding wheels.
