Abstract
Abrasive tools and a grinding process are for use in the manufacture of hypodermic needles. In particular, a formulation including selected bond components, and a process for manufacturing grinding wheels having an embrittled bond permits a new method for grinding of fine hollow metal tubes to shape the tips of hypodermic needles with the substantial elimination of metal burrs or fines from the grinding process.
