EDM Discharge Machining Explained: Process, Tooling and Machine Selection -2026 -10-14

A 0.6 mm inside corner in a hardened H13 mold insert forces a small end mill into 52 HRC steel, and that is a tool-breaking job most shops would rather decline. EDM discharge machining sidesteps the ...

What Does EDM Stand For in Machining? Electrical Discharge Machining Explained -2026 -10-07

Harden a mold insert to 52 HRC and the milling cutter that shaped it in the soft state stops being an option. The corner radius is 0.3 mm, the rib is 40 mm deep, and the tool simply cannot reach into...

A Guide to CNC Machining for Aerospace: Tolerances, EDM and Machine Tool Choices -2026 -09-30

A job shop is quoting a titanium bracket: Ti-6Al-4V, 240 mm long, two bearing bores held to ±0.010 mm, a 0.8 mm-wide seal groove that must finish at Ra 0.4 µm, and a first article inspection report d...

CNC Machining Centers Explained: Types, Key Specifications, and How to Choose -2026 -09-23

A machining contractor once brought us a quotation for 2,000 pump housings with a simple requirement: a ±0.008 mm bore tolerance, documented on every part. The shop's manual mills could hit that numb...
