The ring gage
was custom machined for WIT from solid carbide and ground to 20 millionths.
If your part has a cylindrical shape, such as a ring gage
, then the polar coordinate system is the most useful (Figure 2).
Major diameter: This can be checked by outside micrometers, go/nogo plain ring gages
, or snap gages, as well as the Thread Trend System fitted with plain rolls.
"First we scan a XXX ring gage
, store the data, scan the ring again, compare the two scans, and see the difference as tolerance bands of about 20 millionths around a perfect circle.
This includes the accumulative error of the ring gage
, the probe, and the recorder.
This standard is intended to establish uniform practices for the measurement of master rings or ring gages
using horizontal methods.
Measurements require no ring gages
for calibration and are not dependent on the dimensions or the 3D geometries of the individual features.
Most boring gaging systems rely on the use of ring gages
or masters as a means of setting.
The CMM can now be used as a 'soft gage' to replace traditional plug and ring gages
and other more expensive form measurement instruments,"
Sporting a relatively small footprint, Lista cabinets are used to store tools of disparate sizes and shapes: reamers, endmills, wrenches, inspection equipment (such as ring gages
and thread plug gages), and other line tools.
The Helios UMG-50 is a 0-4" ID/OD single-axis measuring instrument for checking precision parts as well as plug gages, thread gages and ring gages
. The instrument is said to measure both ID's and OD's fast and accurately.
Gage calibration: In the company's in-house gage-calibration program, the TR-300 is used to check ring gages
and verify and check the quality of all production and process equipment.
