Abstract
A cutting wheel includes a body having a bond material. The bond material comprises at least about 31 vol % of a total volume of the body. Additionally, the body includes abrasive particles contained within the bond material. The abrasive particles include a first type of abrasive particle including black alumina with at least about 10 vol % of a total volume of the abrasive particles including black alumina. In some instances the cutting wheel can include a chop saw, while in other situations, the cutting wheel can include a cut-off wheel.
Claims20
A cutting wheel comprising:
- a body including:
- a bond material comprising at least about 31 vol % of a total volume of the body;
- abrasive particles contained within the bond material, the abrasive particles including a first type of abrasive particle including black alumina, wherein at least about 25 vol % of a total volume of the abrasive particles includes black alumina, and wherein the abrasive particles include a second type of abrasive particle selected from the group consisting of brown fused alumina, white fused alumina and zirconia.
A cutting wheel comprising:
- a body including:
- about 35 vol % to about 45 vol % bond material for a total volume of the body;
- and
- abrasive particles contained within the bond material, wherein the abrasive particles include black alumina and brown fused alumina with a content of the black alumina abrasive particles for the total volume of the body being greater than a content of the brown fused alumina abrasive particles for the total volume of the body.
A cutting wheel comprising:
- a body including:
- about 35 vol % to about 45 vol % bond material for a total volume of the body, the bond material comprising about 28 vol % to about 36 vol % of a phenolic resin material for the total volume of the body and about 5 vol % to about 12 vol % of a pyrite material for the total volume of the body;
- about 40 vol % to about 50 vol % abrasive particles for the total volume of the body, the abrasive particles comprising about 28 vol % to about 36 vol % black alumina abrasive particles for the total volume of the body and about 9 vol % to about 18 vol % brown fused alumina abrasive particles for the total volume of the body;
- and
- about 8 vol % to about 19 vol % porosity for the total volume of the body.
