FEATURES • Alumina-ceramic abrasive stone for removing burrs from hard materials such as ceramics that ordinary stones cannot handle.
• Can be used both for steel gauge blocks and CERA Blocks.
• Both surfaces can be used.

Removing burrs
(1) Wipe any dust and oil films from the gauge block and the Ceraston (or Arkansas stone) using a solvent.
(2) Place the gauge block on the Ceraston so that the measuring face that has burrs is on the abrasive surface of the stone.
While applying light pressure, move the gauge block to and fro about ten times (Fig. 1). Use a block rubber for thin gauge blocks to apply even pressure (Fig. 2).
(3) Check the measuring face for burrs with an optical flat.
If the burrs have not been removed, repeat step (2). If burrs are too large, they may not be removed with an abrasive stone.
If so, discard the gauge block.
