  • Eight Tips For Effective Grinding The Fabricator

    Eight Tips For Effective Grinding The Fabricator

    Together, the PQI, SDI, and RCI indices can provide the basis for an equivalent grinding index (EGI), which in addition to the three indices would also take tonnage, track geometry, rail metallurgy and friction conditions into account, they said. Initial efforts will focus on transit, since a few of them are already collecting the necessary.If the disc is 0.25 inch thick, then a 0.5 in. wide wear pattern should be showing on the wheel. If the wear pattern is, say, 0.75 in., your approach is too flat, which means too many of the grinding disc’s grains are engaging at once. If the pattern is only 0.25 in. wide, your angle of approach is too high. 6. Keep consistent pressure.
