· . of can present difficulties since the metal has a tendency to load the wheel, which can lead to higher temperatures at the metal/wheel interface, high residual stresses in the ground surface and a generally unsatisfactory surface finish. These difficulties can be largely eliminated by the choice of suitable wheels ...

· The paper initially reviews the published research on intermetallics. Details are then presented of a 4 factor, 2 level, full factorial experiment, undertaken to assess the grindability of a gamma γ aluminide Ti –45 Al –2 Nb –2 Mn +0.8 vol. % TiB 2 XD™ when surface with SiC wheels. Tests involved variations of abrasive grit size, wheel grade ...

· Ive been a lot lately. The key seems to be keeping the blade cool, running the belts slow and rough with a coarse belt. I dip the blade every pass, sometimes every half a pass to avoid work hardening. When this happens, the blade wants to sort of skip across the belt. I also use 36 or 60 grit ceramic belts run at ...
