Thanks of your recommend for the cast iron plate ,actually we have made a cast iron plate size 500mm and thickness of this plate is 40 mm and we send it to a factory and they grinding both sides ,now we are going to send it for making some cross hatch pattern ,but we do not know the sizes of these pattern we have to make on it ?

and if we make the spaced at 25 mm is it good ?

When I answered the original question, I was not expecting you to construct a lapping plate from scratch. They can be purchased as a complete unit, ready to use. But if you are determined to make your own, this pattern should work.

If your homemade plate does not give you the results you're looking for I suggest contacting a company like Lapmaster to see if you can buy just a plate for hand lapping. I'm not affiliated with them but I am aware of a major seal manufacturer that uses their products.
As for cost, I have no idea.
