Abstract
A dressing wheel has a disk-shaped base body centered on an axis and formed with an annular groove also centered on the axis and having an inner surface. A multiplicity of abrasive elements distributed along the groove are in direct contact with the groove inner surface. Matrix powder fills the groove between the elements and between the elements and the groove surfaces. A hardened infiltrating agent, e.g. solder, fills interstices of the matrix powder.
Claims20
A method of making a dressing wheel, the method comprising the steps of sequentially:
- positioning abrasive elements along an annular groove opening at a face of a base body;
- securing the abrasive elements in the annular groove;
- filling the annular groove between the abrasive elements and between the abrasive elements and surfaces of the annular groove with a matrix powder;
- infiltrating interstices of the matrix powder with a liquid infiltrating agent;
- hardening the infiltrating agent and thereby bonding the matrix powder to the abrasive elements and to the annular groove surfaces;
- and
- machining off an outer surface of the bonded together matrix powder, hardened infiltrating agent, and abrasive elements.
