Abstract
A blade assembly is formed from multiple blades assembled adjacent each other with openings in respective blades arranged to form a passageway passing through adjacent blades.
Claims19
A plurality of cutting blades formed either as diamond cutting blades or carbide cutting blades assembled into alignment according to a common reference associated with each blade in an assembly, the assembly comprising at least first and second blade cores having respective first and second shaft walls defining blade shaft openings and respective first and second flow walls defining first and second flow openings wherein the first flow opening has a first geometry and first cross-sectional area in the blade core and first radial position and first arcuate position relative to a common reference on the first blade core, and wherein the second flow opening has a second geometry and second cross-sectional area in the blade core and a second radial position and second arcuate position relative to a common reference on the second blade core, wherein the first and second flow openings are different from each other in at least one of geometry, cross-sectional area, radial position and arcuate position.
A plurality of cutting blades formed either as diamond cutting blades or carbide cutting blades assembled into an assembly with adjacent cutting blades aligned with each other according to respective blade shaft openings and respective common reference points, the assembly comprising first, second and third blade cores having respective blade shaft openings and respective common reference points, wherein each of the first, second and third blade cores include respective first, second and third flow walls defining first, second and third flow openings having respective geometric centers in the flow openings and together defining a flow passageway having a central axis extending through respective ones of the geometric centers and wherein the central axis is other than normal to the first blade core.
A cutting blade assembly comprising a blade shaft and first, second and third blade cores having respective blade shaft openings through which the blade shaft extends, wherein each of the first, second and third blade cores further include respective surfaces engaging a reference element on the blade shaft to position each of the first, second and third blade cores circumferentially on the blade shaft, and wherein each of the first, second and third blade cores include respective first, second and third flow walls defining first, second and third flow openings defining a first flow passageway extending in a first direction other than parallel to the blade shaft, and respective fourth, fifth and sixth flow walls defining fourth, fifth and sixth flow openings defining a second flow passageway extending in a second direction other than parallel to the blade shaft and different from the first direction.
