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 machining (EDM).  

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.

Sinker EDM Features Compact Size

Sodick introduces the C32 CNC sinker EDM, featuring a compact design that fits into a 3. 5 ft. × 5.

Rotary Indexing Spindle For EDM

Hirschmann Engineering has combined the H80R. MNCM high speed rotary indexing spindle with the H1625. AC3 fully programmable, variable speed AC control to produce miniature, round parts with small diameters and fine finishes.

Exploring Niches With New EDM Technologies

A shop specializing in wire EDM for large mold components now offers EDM “turning” of small, intricate parts. Despite the potential risks involved in early adoption of new technologies, the shop believes this practice gives it a leg-up on the competition and lets it gain experience with alternative machining techniques before offering them to customers.

Check Machine Details Before Delivery To Your Shop

When I am interested in writing about a new type of machine tool, I like to visit a shop or plant that has a representative model in place. Getting this user’s perspective is more objective and more relevant than just picking up info from other proponents. Writing the article is more fun, too. So typically, I talk

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.

Graphite Series Offers Strength

Toyo Tanso’s TTK-4 grade of graphite is the fine-grain offering of the TTK series product line of ISO statically molded graphite. It is suitable for the medical and aerospace fields. The key attributes of this grade are said to be strength, machineability and resultant-quality surface finish. The company’s other
