The CNC machined Edge Pro aluminium lapping film blank is used as a mounting platform for the lapping films. The lapping films adhere to the aluminium blank, then the aluminium blank mounts in the stone arm so it can be used like a stone.
Years ago Edge Pro made the lapping film blanks from two pieces of aluminium extruded bar. The next breakthrough was one piece of aluminium extruded bar with a 1" x 6" piece of glass adhered to the top.
Now Edge Pro are on the next level! The new modern lapping film blank is made from one solid piece of fully machined aluminium. The top surface has been machined to be as flat as possible.
The top surface has been machined to be as flat as possible. The Edge Pro logo has been engraved on the back so you know Edge Pro must be proud of it!
