Depth seam allowance go-no gauge is used to test the inner hole diameter and depth of the cylinder. If the go end can go through the measured hole and the no go end can’t, hole diameter of the measured workpiece is qualified; if the go end can’t go through the measured hole or a part of the no go end can go into the measured part, hole diameter of the measured workpiece is unqualified. If put deep into the hole, the go end is located between the two ends, depth of the measured workpiece is qualified; if put deep into the hole, the go end is located outside the two ends, depth of the measured workpiece is unqualified.
Scope of application:
Suitable for workpieces of which inner hole diameter and depth can be measured simultaneously (blind hole or step hole)
Suitable for measurements of blind hole, step hole and semicircular hole (more than 180°)
Only used for measurements of parts of which hole diameter tolerance is more than IT8 and depth tolerance is not less than 0.2.
