I asked Sam what else he would like EDM Today readers to know about MMK. Sam replied, saying he would like readers
to know that MMK goes back to 1948 and has many decades of experience designing and building high-quality rotary
tables. Sam added that he would also like EDM Today readers to know that MMK builds rotary tables for much more
than EDM applications. He invites our readers to visit his website to see the breadth of the MMK product offering.

Although they have a new name, they have been manufacturing EDM wire for a long
time. Many EDM readers have no doubt wondered where the new name came from.
We asked Proterial about it, and they shared the origin of the name. The word is divided into two parts. The fi rst part,
PRO, comes from their three PROs:
• Professional
Work That Exceeds Expectations

• Progressive
A Spirit That Keeps Challenging
• Proactive
An Enterprising Attitude
These three PROs are the essence of Proterial’s Corpo-
rate Philosophy. The second part of the name is based
on what PROTERIAL manufacturers, MATERIAL. The
combined PROTERIAL embodies both the high-perfor-

selected pure materials, drawing expertise, and high-quality dies developed in
their technical center.
Recently, a 0.016” version of HBZ-K was released that targets large aerospace and power generation parts.
The larger diameter wire allows for higher power and faster

to forecasts for even larger parts and believes that need for
larger wire will grow.
Another new wire recently developed is the type HBZ-SS. This
is considered a special wire developed for line mark reduc-

Proterial product offering is the type ABZ wire. This wire is
designed for taper cutting less than 20° angle. A similar wire,
type ABS-A, is considered ultra-soft and developed for taper
cutting between 20° and 45° angles.
