6.5" dia. x 1" Thick Lower Platen

Lower platen is 1" thick and 6.5" in diameter. The platen is hardened to a Rockwell hardness of 55 HRC and is precision ground to maintain planeness within .0005" in any 6.00" direction. The surface is scribed with concentric circles for test specimen centering and electroplated with nickel for wear and rust resistance.

This is used with the CM-0030, CM-0100, CM-2500, and CM-3250 series of machines.
