#CMT# #/CMT# The cutting blade (1) for hard materials as a circular or band saw, with a grinding action, has a body (10) with cutting particles (20) at the end side (11) projecting beyond the side surfaces (12,13). The grinding particles at the end side are larger than the particles (21) on the side surfaces. The grinding particles are of diamond or cubic boron nitride #CMT#USE : #/CMT# The cutting blade is for use on hard materials e.g. sapphire. #CMT#ADVANTAGE : #/CMT# The cutting blade has a relatively thin cutting width. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show schematic views of the cutting blade in prior art and in the new version. 1 : cutting blade 10 : blade body 11 : end side 12,13 : side surfaces 20 : end grinding particles 21 : side grinding particles #CMT#METALLURGY : #/CMT# The cutting blade body can be of a nickel alloy and preferably a nickel-cobalt alloy. |
