Figure 3.5 Preparation damage arrows in annealed CP titanium 500X, DIC, Krolls reagent. A Planar grinding machine, like the PlanarMet 300 planar grinding machine shown in Figure 3.3, utilizes a fixed abrasive stone for rapid sample grinding. This type of automated grinder produces planar samples in 1-2 minutes replacing up to 3 traditional grinding steps.
Figure 4-12. A square file begins removal of the corner web left by an end mill, anda three-square file removes the remaining metal to leave a square inside corner.
Figure 4-13. A coating of tungsten carbide particles produces a file for hard materials.
Files are inexpensive, portable and able to fit into tight spots, but because today there are faster methods to remove metal, files are mainly used to sharpen, smooth edges, remove burrs, or to make fine adjustments. Still, they remain an important and handy tool, indispensable to mold makers, tool and die makers, prototype makers and to gunsmiths.
