Polishing machine for Stainless steel small size cups

A. Mass finishing can polish or burnish depending on what you put into the machine as a media. It was very commonly use to polish silverware at big restaurants. They call it polishing but it was actually burnishing. Media used was porcelain and the liquid chemical was important to the operation.

Thank you for yours answer and now I am cleared about this machine. Even I have contacted the vibratory machine manufacturer and will be ordering this machine soon.

If I have any doubts then please help me.

Thank you sir

Hi JASWINDER. These are stainless nails? I don't think they should be polished with steel balls. They will rust.

Regards,

A. Ted is right. If you need a bright finish on nails, the normal method for mass finishing is to tumble what is called part on part with no media.

A. Not sure your centrifugal system is set up to run dry organic media or not. That would be my first choice. I lieu of that a wet system using a mix of small porcelain shapes would be good; however, the chemical compound is very important. If your SS parts are machined, you may need an abrasive process first.

It is possible to do bulk electropolishing of small ss part in our Universal electrolyte. We deliver the technological process, electrolyte composition and the device drawings. The small prototype device can be delivered too. Such stainless steel electropolishing technology (for all types of SS alloy) has been licensed to Bama Technologies from Turbigo, Italy. See the brochure called "Italian Fasteners". It is both in English and Italian.

A. Yes you can dry polish in a vibratory system; however, there are some concerns.
#1 time to process parts are long, 24 hours or more.
#2 you need to cover top of machine and seal drains
#3 You maybe able to process in less time by using treated organic media and adding a porcelain media shape to add pressure to the parts.

A. Any mass finishing system will work. It is more a question of your parts size and volume of parts to be processed. Bottom line, your parts have to move freely in an X,Y, and Z motion without too much contact with either the walls of the machine and other parts. See steps 1-3 previous. Media suggestions: 50#'s = 1 cu.ft. Must add new cup full every batch.

A. YES! I don't think you mentioned about the surface finish requirements. Meaning to get the radius break, you need to use a rough cut ceramic media in a wet process. Time cycle is determined by hardness.

A. OK It is not easy to get a polished finish on steel or SS in a short time cycle. There are a number of steps. It can take 3 to 5, depending on what you are looking for. First of all, you need to know the Ra or RMS of the surface before you start. If you you are working with processes materials, more than likely you have close to a 32 RMS. A fast cut (coarse) ceramic over a one hour period (maybe 2-4 hrs-depending on hardness) should get you down to about 22-24 RMS. The next step should be a fine cut ceramic for another hour to 4 hrs. That can bring that surface finish down to 16 - 18 RMS. Now if you are looking for brightness/reflective finish, you can go to either porcelain or steel or SS media with a burnishing compound for another for another hr or two. The end results may not be smooth but bright. If you want smooth, you may want to go to a dry process using treated organic media instead of the 3rd step wet process mentioned.
Actually you can do a 2 step dry for better results.

At the very least, if processes like what AF Kenton suggest gets you closer to the finish you want, then your hand buffing workers will spend less time on each part.

A. See editors note. FYI before you try to polish, make sure your surface profile is less than 18 RMS. That might mean 2 or 3 deburring steps prior to polishing

A. Dear Kyler,
For your jewelry I would suggest you use mass media polishing machine. This machine works with various media like Ceramic/ Plastic/ Zircon/ Walnut/ Wood/ etc. For every style of jewelry there is a particular media which should be used. Thus, after the initial deburring process by hand (filing with files, emery paper, etc.) you can use the ceramic media to get the desired result & then Walnut & Wooden media to get the high shine. Once this is done you can load the jewelry in the steel tumbler or vibrators and get the desired result. But the steel process should be done gradually overnight in a mild soap solution with the tumbler rotating at around 6 -7 rpm.
All the best to you.
Warm regards,

A. Esi Ebi,
I don't know how to answer your questions, but please don't use carbon steel media to do polishing of stainless steel. You will cause yourself rust problems. Use a non-ferrous media.

A. Not sure about your machine's ability to move steel media. What you need is a good smooth rolling action of the media, so fill depends on the machine. Normally the more media the better the results. Compound should have good lubricity to it

A. Follow up. Compound is important for burnishing. Best results are normally with acidic compound with good lubricity. Regarding fill level, if your media is not moving, your machine is too weak. If your media is jumping more vertically than rotating, then your machine is too powerful or fill level is too low. Lastly, you might want to consider dry burnishing using porcelain and dry organic media. Most machines can handle that mix and it does a good job
