There is a new development from Makino’s R&D engineers that I would like to tell you a little about.  Its called “Pico Precision Wire Guide System”.  This a new offering on SP and Uj series machines, and can be ordered from the factory or retrofitted to existing installed machines.  The Pico Guide System was designed to provide reliable, flawless threading of small holes in a tight matrix, or for highly accurate cutting of variable taper lands for stamping tooling.  This allows Makino to offer the only real “choice” in wire guide systems on a WEDM.  We will still offer, and believe that our standard Split V-Guide system is best for about 80% of WEDM work today, and will still offer this tried and true system. 

What kind of wire guide system do you use, and what problems have you had? Post comments or email me at jkiszonas@makino.com.

We were posed with a good question the other day - Why does Makino EDM take such interest in aerospace?

We have a long history of working with the aerospace industry.  As a supplier to all tiers of aerospace manufacturing, we have provided machine tools, spindles, machining centers, customized machines, turnkey systems, and part processing development to this industry.  It was only natural for us to want to help bring the aerospace community the latest information available concerning the use of EDM in manufacturing parts for critical aeronautical and aerospace applications.  

If today’s EDM machines leave little or no recast, HAZ, micro-cracking, or change in surface hardness, then secondary operations after EDMing, like milling or grinding, can be eliminated.  This would mean that the aerospace industry could now change their restrictive usage specifications for EDM that date from the 1970’s, and reduce time and expense related to these secondary operations.
