Ultrasonic Machine

Recommended Posts

Hello all! I would like to buy an ultrasonic washing machine. Elma caught my eye but it is way out of my hobby budget. So I have a few questions:

-what do you guys use, with what substances and what are your impressions?

-I've seen that different producers use different frequencies, from 28khz to 42khz - can anyone compare the use of one freq against another?

-how much power do I need? 30w, 50w, 100w?

Good morning Bogdan, I use the first machine displayed below. If I was purchasing again, I would probably purchase the one below, as I fill it with water at 50-60 degrees from the kettle, and when it is running it generates heat anyway.

The answer to your second question is yes. I have small amounts of cleaner in little jam jars and suspend the in the water in a gauze basket.

 This is what I use and has always given me good results:

only one machine, the beakers are also part of my equipment but bought separately.

I use the same (L&R) cleaning solutions with my L&R cleaning machine getting excellent results. I did try Elma which gave the same cleaning results but I thought it was a bit smelly.

Geo, was your recommendation for the second one based purely on price or are you unhappy with the first model.

I wasn't over impressed with the heater, so I don't see the point in paying the extra. As I said, first heat up the water in a kettle to the temperature that you require, and the heat generated by the ultrasonics will keep it pretty much where you need it for the duration of the washing. Also remember that even cold water will do, as it is the high frequency vibrations that blast the muck off.

I personally think that the ultra sonic action does most of the work & the cleaners are much the same as each other

I think your spot on CB, the cleaners de-grease and brighten the finish. I get excellent results with priory cleaner, it is ammonia based and is super value for money.

Yes purchased some last year very good for the clock cleaning.

@Geo: do you think I need a 2L ultrasonic? I believe a 500ml is more the enough. Or do you think the bigger one has more ultrasonic-waves/cavitation power?

 

 

 

 

p.s.: Please assume I say Hello in all my posts, I mean no disrespect!

The 500ml will be more than enough capacity wise for watch parts. Just make sure that you get one that about 40khz to give efficient cleaning, some of the really cheap ones are less than that. The only reason I wanted the larger size; I wanted to clean motorcycle carburettors.

Regarding hello, I only tend to say hi or hello when I initially get involved in a conversation for the first time. :)

I use the exact same machine, works fairly well and I'm happy with it. Cleaning fluid in a little jar with the parts to clean, plain water in the machine, jar in the water, in the plastic basket.

Same here minus the plastic basket!

    • No real question here, I managed to clean and reinstall this straight. But I just thought I would share this silly design for a balance cap jewel on an old Junghans pocket watch caliber J32. The screw is in the center, the jewel eccentric; the opposite design from every other cap jewel I have ever seen. But it has no steady pins beneath so tightening the screw means the cap jewel wants to rotate away from the hole jewel. Without an automatic oiler, this took about 6 tries to oil and screw down the cap without spinning it away. A tiny bit of Rodico didn't really help. Happily they don't make them like this anymore.
    • Thanks for your most appreciated assessment with this. I will purchase a new movement. 
    • Sorry I am confused by step 4. Which screw? There is the balance cock screw. I don’t think that is what you are talking about. The only other screw I see is on the side of the swan neck regulator. I do t think that is the one you are talking about either Well I managed to make it worse again but I could take pictures.  I had put the balance cock partially in place with one locator pin in. I wanted to remove it and I know I should use my screwdriver in the slot to move it off the pin but I didn’t l pulled wit my tweezers and it stuck then gave suddenly and was thrown a few inches away and of course the hairspring got tangled (a coil was above the cock) and untangling it from the cock deformed it.    I am going to try to put it back in shape and I will likely post more pictures after shortly. I’ll wait for feedback before reattaching it to the cock I am sorry I think I’ll give up. I was trying to remove the tangle. I had previously succeeded but now I just made more of a mess with this new tangle.  Lf you see my spring it is now just a knot.  Let’s keep a positive attitude. The movement was already broken. It was working but couldn’t be used. So what if it can’t run anymore… I went on and reinstalled the mainspring in the barrel by hand and managed to put the arbor back in.  Now I need to close the thing!  
    • Hello and welcome from Leeds, England. 
    • OK, bad video... Almost all of them are. To attach the spring (stud) to the cock: 1. Put the cock on the table top upside down.  Open the regulator if closed. 2. Put the balance on , align the stud above the hole for it in the stud carrier. 3. Help the stud to get in the hole by gentle pressing. 4. When it is in, grasp the cock with balance with tweezers (from aside, not from above), then get it between fingers, not changing the horizontal position, then tighten slightly the screw. This is the moment to correct the high position of the stud - it's top must be even with the carrier. Now tighten the screw. 5. If the outer coil is out of the regulator, move the regulator to the max to '+' position, then guide the spring to get in the regulator. Now You can return the regulator where it was and close it above the spring
