Abstract
Official abstract text for this publication.
A grinding wheel including an impeller structure for circulating coolant within the wheel defining a plurality of grooves. An angle between a second wall of each groove and a tangent to the outer circumference adjacent the groove outlet is defined based on the desired coolant flow rate, the predetermined wheel rotational speed, the radius of the outer circumference of the impeller structure, the combined surface area of the groove outlets, and a desired angle of exit of the coolant being at most 15 degrees. Also, a wheel is disclosed where the angle of the second wall of each groove is defined based on the desired coolant flow rate, the combined surface area of the groove outlets, the tangential speed of the wheel, and a value of n being at least 0.9 and less than 1. A method for distributing a coolant to a grinding site is also discussed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A grinding wheel for grinding a workpiece through rotation at a predetermined rotational speed, the wheel comprising: a grinding wheel body having a hub defining a wheel inlet; and an impeller structure disposed within the wheel body around the hub, the impeller structure having a plurality of circumferentially spaced apart blades, the blades cooperating to define a plurality of grooves each extending between a groove inlet end in fluid communication…
