Frequently Asked Questions (FAQs)
1. What are the three styles of small hole gauges?
There are two styles of small hole gauges: half-ball and full ball. These gauges are inserted into the bore and adjusted until a light pressure is felt. They are then removed and measured against a micrometer or caliper to determine the diameter.
2. Which gauge is used to measure hole diameter?
Plug gauges are used to measure hole diameter. They come in various shapes and sizes, including straight cylindrical, tapered, threaded square, and splined holes. Plug gauges have a 'GO' end, which is the minimum limit size, and a 'NOGO' end, which is the maximum limit size.
3. What is the difference between small hole gauge and telescoping gauge?
Small hole gauges are used for measuring holes ranging from 3mm to 13mm in diameter, typically for valve guides. On the other hand, telescoping gauges are used for larger holes, measuring from 8mm to 150mm in diameter, typically for cylinder bores.
4. What is the rule of thumb for gauges?
The rule of thumb for gauges is to ensure that the gage performance rating is at least ten times the tolerance. For example, if the tolerance is ±0.001 in., the gage should have a performance rating of at least ±0.0001 in. A gage GR&R (Gage Repeatability and Reproducibility) study can help determine the gage performance.
5. What is the most common limit gauge used for inspecting the hole diameter?
The most common limit gauge used for inspecting the hole diameter is the plug gauge. It is widely used for checking the size of holes and comes in different sizes and shapes to accommodate various types of holes.
