Abstract
Provided is an abrasive material having a grinding force more appropriate to the purpose of surface finishing. The abrasive material is intended to be used for surface finishing by spraying onto a workpiece, and comprises a plurality of abrasive material particles each comprising a core, a binder, and an abrasive grain layer formed on a surface of the core via the binder, wherein the binder is a mixture of a non-curable adhesive used as a main ingredient to provide tackiness and another agent used to adjust hardness according to a desired surface roughness of the workpiece. The hardness of the binder is adjusted to be higher or lower than that of the non-curable adhesive itself as a main ingredient. The binder may have the property of a cured material or the property of a fluid.

An abrasive material to be used for surface finishing by spraying onto a workpiece, the abrasive material comprising:
- a plurality of abrasive material particles, each of the abrasive material particles having a core, a binder, and an abrasive grain layer formed on a surface of the core via the binder, wherein the binder is a mixture of a non-curable adhesive used as a main ingredient to provide tackiness and another agent used to adjust hardness according to a desired finished surface roughness of the workpiece.
A method for making an abrasive material, composed of abrasive material particles, to be used for surface finishing by spraying onto a workpiece, the method comprising:
- attaching to the surfaces of the cores of the abrasive material particles an adhesive grain layer by a binder, wherein the binder is a mixture of a non-curable adhesive used as a main ingredient to provide tackiness, and another agent used to adjust hardness according to a desired finished surface roughness of the workpiece.
