A recent account of a HEAT retrofit at a Makino SP43 owner:
Today I installed HEAT at one of our new customers. When I first tried to copy the .010" e conditions it produced an error that indicated there was not enough room. I deleted all conditions from 9000 thru 9099. This opened enough space.
We decided to use the special pump parameters on the first job. It was not "both" away but "one" away. It was a 2" tall piece of cast stainless steel, a repeat production job, 24 pieces this time. The cut time had been 1:04 for the part done the day before. High speed 1.2 was used but the part was in a fixture that put the bottom of the part .5" above 0. The est. cut speed was .137"/min. The actual cut speed was about .084"/min. when using standard conditions and pump parameters. I used the same 1.2 e condition and put the steel laminar nozzle on the bottom where the bad flush was. I kept the steel sealed off nozzle in the top because it was sealed off. The cut speed increased from .084"/min to about .124"/min. This is a dramatic increase. He has a fixture that holds nine parts, which had a total cut time of 9 hours 36 min. Using the enhanced flushing brought the per part time from 1:04 down to 44 minutes. This made the time to cut a complete fixture 6 hours 36 mins. This is better than a 35% time savings. The customer is very excited about this!
