Abstract
A grinding wheel coolant distributor system is set forth utilizing a frusto-conical receptacle attached to a grinding wheel body which receives coolant from a fixed single point inlet and delivers the coolant along radially-outwardly and diverging inner sidewalls to a plurality of passages extending through the grinding wheel body to a distributor plate, which in turn, through centrifugal force distributes the coolant in a uniform thin film flow to the active abrasive face of the grinding wheel.
Claims12
A method of distributing a coolant to the active abrasive face of a grinding wheel which comprises:
- delivering a coolant from a single fixed inlet to a frusto-conical surface on one side of the grinding wheel,
- applying centrifugal force to said coolant to flow the same radially-outwardly along said frusto-conical surface,
- flowing said coolant from said frusto-conical surface through passages in said grinding wheel to an annular groove formed on an opposite side of the grinding wheel, and utilizing centrifugal force to distribute said coolant in a uniform thin film flow from said groove to said active abrasive face of the grinding wheel.
A grinding wheel coolant distributor comprising:
- a grinding wheel body having a front face, a rear face, and an annular rim provided with an active abrasive face;
- means of rotating said grinding wheel body about a central axis;
- frusto-conical means secured to one surface of said grinding wheel;
- distributor means secured to an opposite face of said grinding wheel with an annular groove therebetween;
- passages extending through said grinding wheel and communicating with said frusto-conical means and said distributor means;
- a flow gap extending between said distributor means and the rim portion of said grinding wheel;
- and
- means for delivering coolant to said frusto-conical means for flow therealong and through said passages to said groove for distribution through said gap to said active abrasive face.
An improved grinding wheel cooling system comprising:
- a grinding wheel body having a rear surface, a front face, and a rim portion terminating in an active abrasive face;
- means for rotating said grinding wheel about a central axis;
- a plurality of passages extending through said grinding wheel body between said rear face and said front face;
- a distributor plate mounted on said front face and having an annular groove directly communicating with said plurality of passages, and an annular gap communicating between said groove and the rim portion of said grinding wheel;
- a fixed single point coolant feed inlet means for delivering coolant to said grinding wheel body;
- and
- frusto-conical receptacle means mounted on said rear face for receiving coolant from said inlet means and delivering such coolant through said passages and to said groove of said distributor plate for distribution through said gap to the active abrasive face.
