Used somewhat like an indicating micrometer except you don't have a micrometer spindle to preset the dimension to be measured. With dial snap gages—gauge, if you will—you insert your standard or master piece and set the dial to zero. Now replace the standard with your test piece and read the deviation on the dial. A lifting lever (included) will make repetitive actions simpler. These items are made in USA by Dorsey and replace the old Standard Gage snap gages made in Poughkeepsie. An optional bench stand will firmly clasp the snap gage so you have both hands free for the inspection. This is a virtual necessity unless you have your own means of holding the snap gage or you need to keep the snap gage mobile. Standard dial snap gages have ranges up to 18", which is impossible on indicating micrometers. These dial snap gages are sold with indicators and lifting levers. You don't have to buy those separately. However, replacement indicators are available. This would allow you to use the same snap gage for inch or metric readings. Or use the optional cartridge adapter to adapt the gage for use with digital indicators or electronic probes. The snap gages are available in one-inch increments because the anvils are adjustable within a 1" range. The dial indicator can be rotated 360° for best viewing. Gage pressure is adjustable so you can safely deal with a variety of materials and finishes. The frame is lightweight, being made of stabilized aluminum. It's sturdy and well balanced. The "Paralloc" mechanism locks the anvil in place without causing it shift and ruin parallelism. Tungsten carbide anvils 5/8-inch square are standard. Within the .50" central square surface, these anvils are flat and parallel within .00015" on sizes up to 4 inches; within .0002" on sizes from 4 to 8 inches; within .00025" on sizes from 8 to 12 inches; and within .0003" on sizes from 12 to 18 inches. All anvil edges are chamfered .016" by 45°. |
