One of our EDM Applications Engineers recently performed some comparison test cuts on a medical production job.  These results show comparative data between the Makino SP43 and one our competitor's machines, as well as between hard brass wire and Versacut H wire.  

Parts : KNEE REPLACEMENT PART (Medical Production)
Material : STAINLESS STEEL
Thickness: 2.500"
Wire Diameter: .012" (brass and coated)
Number of passes - 1 rough, 1 skim
MAKINO SP43 (WITH VERSACUT H)
Cutting Time : 1 Hour 25 Minutes.  (1.42)  (85 min)
Wire Consumption : 1071 Yards.
MAKINO SP43 (WITH HARD BRASS WIRE)
Cutting Time : 1 Hour 54 Minutes.  (1.90)  (114 min)
Wire Consumption : 1471 Yards.
COMPETITOR (WITH HARD BRASS WIRE)
Cutting Time : 2 Hours 20 Minutes.  (2.33)  (140 min)
Wire Consumption : 1647 Yards.
The Makino SP43 was:
25.4% faster in this application when using VersaCut H compared to hard brass wire.
18.6% FASTER than the competition when using Hard Brass Wire.
39.3 % FASTER than the competition when using VersaCut H wire.
And had:
27.2% Less wire consumption in this application when using Versacut H compared to hard brass wire.
10.7% LESS wire consumption than the competition when using Hard Brass Wire.
35% LESS wire consumption than the competition when using VersaCut H Wire.

Since this testing was done on the floor of a Makino customer, the competitor's machine was not tested with Versacut H.  I would expect, however, that even the competitor would see a substantial difference in cycle time and wire consumption by switching from hard brass to Versacut H wire, assuming of course that the competitor's machine can successfully run coated wires as well as brass wires.
