CORRECTION METHOD FOR SUPER GRINDING WHEEL AND DEVICE FOR THE SAME

摘要

PURPOSE:To have an uncomplicated way of dressing a grinding wheel with super abrasive grain by allowing a dressor, whose tip is provided with a grinding liquid supply hole and an exhaust groove, to have contact with the grinding wheel and by supplying a grinding liquid containing abrasive grain. CONSTITUTION:The body 6 of dressor is coupled with a shank 8, and the foremost part is provided with a correction end-face 10 consisting of diamond dust sintered with metal bond. The shank 8 and dressor body 6 are provided with a supply hole 9 for the grinding liquid which is open at the correction end-face 10. This end face 10 is also equipped with a radially oriented exhaust groove 11 for grinding liquid. This dressor is mounted on a moving arm 12 put in contact normally with the grinding face of the grinding wheel 5 to supply the grinding liquid containing abrasive grain through a piping 13. By dressing in such a way, correction of grinder wheels with super abrasive grain such as diamond and CBN can be easily made.
