"ALUMINUM GRINDING"



2005

Good afternoon Sirs, I have some questions, I need quote one aluminum plate of 16"x24"x0.500", but the customer requirement is "aluminum tooling plate with grinding and mirror finished". The Customer show me a sample and it's likes a mirror.

The customer comment me that he need the grinding finished by motives of flatness.


My question are:
1.- It is possible to grinding he surface of the aluminum plate? and how it is this possible?
or
2.- Somebody would say me where I can buy the aluminum plate with this mirror finished?

Aluminum is very soft so it tends to clog most every kind of abrasive wheel thus leaving deep scratches. It is better to machine very fine with a cutting tool, then take it to a mold polishing shop that has experience with aluminum. Then, have it chrome plated and polished back again. Another option is to nickel+chrome plate it w/o final polish if a shiny aspect is desired and severe wear is not an issue.

It is possible using the blanchard grinding process. You will typically get around a 25 RMS on Cast Aluminum Tooling Plate (Mic-6, Alca Plus). You can find more information on these products from Alcoa or Ryerson.

RMS 25 is far from being mirror. I doubt any grinder will give you mirror finish on aluminum. You need a lapping machine or manual polishing. Of course you can have it plated for better hardness and durability.

To make the mirror polish, it's best if you can find any articles in the web with the words "lapping".

The search can include computer heat sinks web pages.

I think you need to reach about 1000-grade polish before any real reflections appear.
