Cutting Porous Ductile Strands

The porous ductile strands 1 are potted in a compound which, after a cutting operation, can be easily removed from the pores. Ice or frozen carbon dioxide is a suitable potting compound.

On grinding or cutting, etc., the ice near the grinding surface is not only removed by the grinding action but in addition, the thin layer 2 of the ice is removed by melting due to the heat of friction and pressure applied during grinding.

Sections 3 of the strands 1 stick out unsupported into region 2. When the grinding tool strikes sections 3, they break off. Pores 4 are left open in the area of the break.

A conventional potting compound, such as an organic polymer, is hard to remove from pores, and the potted strands are worn down gradually by the grinding action and thus, the desired exposed pores 4 are closed by smearing of the ductile strand material.
