SETTING RING 15MM 0.001MM ACC.

Setting rings are most commonly used for setting bore gauges, this is the fastest
most reliable method because the part to be gauged and the setting ring have the
same geometric shape. Ring gauges are metrology tools that are used for gauging
the outer diameters of pins, shafts, splines, fasteners, dowels, studs, and other
machined cylindrical parts.

The ring gauge is a ring-shaped measuring instrument used to measure the outside
diameter of cylindrical objects such as pins, shafts, splines, fasteners, dowels,
studs, and other parts of the machine. Ring gauges are usually made of stable materials
such as chrome plated tool steel and carbide which provide greater service life.
This tool is very precise (exceedingly tight tolerance) which is used as an outer
diameter gauge.

The main function of the ring gauge is to determine by ‘go’ or ‘no-go’ whether
the measured part is in accordance with the specified dimensional tolerance. The
use of ring gauges allows inspections of machine parts to be made very quickly without
the need to use micrometers, calipers, thickness gauges, or other measuring instruments
which can take longer to conclude its quality.

Ring gauges are also effective for checking roundness at higher levels. Measurements
with this tool are used as a standard to set the bore gauge, which can then be used
to determine whether there are deviations from the nominal size.
