Identify older machines

Jewelry Discussion

Can anyone identify or comment on two older machines I have acquired.
One is an “Ultrasonic by Jelenko” Model U-2, output 80 KC, 125 w., 117
v., 4 a., with 30-min. timer. It looks like 1950s design. Is this
spec anything close to modern cleaners? It seems to buzz and shake as
designed. The other is an A.I.T. Super Dyna Myte automatic diamond
bevel edging machine, Mark V, 3,250 rpm, half HP. It has a cast
aluminum body, with sump for coolant, covered with white powder
build-up. Maybe was used for glass or tile? Has a 7 inch diameter
wheel apparently loaded with diamond chips. Potential for limited
lapidary or metal cutting, scoring, faceting? I’m going to figure out
some use for them, any ideas?

Your ultrasonic cleaner was probably made by Branson or L&R. In any
event if it is in need of repair…thats what we do here at Lone
Star Technical Services. This machine will probably preform as well
as or better than some of the newer units. See…older is sometimes
better (grin)

Hope this helps

Andy,

I have heard of this ultrasonic though I don’t see them often at all
anymore; the specs are correct for that unit; the 80 kHz is not very
common for jewelry and lapidary use–the 40-43 kHz is the most common
for jewelry use. The buzzing is normal although you can’t really
tell how well it’s working until you try cleaning with it. We have
test equipment to test and repair ultrasonics here and if repair is
needed, estimates are free. Hopefully your machine is working just
fine; if I can help in any way, please feel free to contact me.
