What is the latest technique for getting
mirror like shining on stainless steel utensils
+++++
I am in charge of the new product development for getting mirror
like finishing on ss utensils without any scratch.We have tried it by
using a flap wheel then giving a coating of buffing compound(made of
calcined alumina and wax) and then polishing the surface .But it is
not giving the required lusture and also it is taking lots of time.Is
there any product available that is specifically made for polishing
ss utensils and a readymade flap wheel already coated with buffing
compound.
I will be intrested on the newest technique for the same.Is the size
of the abrasive powder is taking a big role ? What is the exact size
range for polishing?I have talked with many people but did not get
the proper answer.
Thanking you,

I don't think you're ready to automate the process yet if "it is
not giving the required lustre", Prasanta. I think you need to find
the right abrasive, the right wheels, and the right polishing and
buffing sequence and get exactly the right lustre. Once that is done,
I think you will find that there are automatic polishing and buffing
machines available which will disperse the compounds as liquids at
the work interface, enabling you to carry out the process at volume
and with speed.

I agree with Ted. You have to master the process at low volume to
proceed to high volume automation. Now, the particle size for mirror
finish will be from 4 to 1 microns depending on your "mirror"
definition. Also important are the previous finish, exerted pressure
and speed and hardness of the base material.

Just an add on for the other good advice. You did not give us any
details on the existing surface finish prior to polishing. That does
mean a lot in determining the proceedures and developing a process
and/or equipment.

Dear Mr.PRASANTA GORAI
- You can try with a polishing pastes which is used for polishing
stainless steel kitchen wares.I dont know the formula.
-- you have to control revolution of polishing device, must be less
than 4000 rpm.
--- pls try with felt(wool or nonwoven) disc/wheel first, than softer
one like cotton wheel,at the end cotton wheel without any paste.take
care overheating.
---- if not satisfied think "electropolishing" as an
alternative.keyword:"electropolishing"
PS:Please ask Mr.Ted Mooney,to give you an idea,what are the right
abrasives, right wheels etc?
Shiny days,
