A dial bore gage is a precision instrument used to measure the inside diameter of a gun barrel. It consists of a rod with a scale on it and a series of interchangeable heads of different diameters. The dial bore gage is inserted into the barrel, and the appropriate head is selected to get a snug fit. The rod is then slowly withdrawn while the dial is monitored for the highest reading. This is the accurate inside diameter of the barrel.
When measuring the inside diameter of a hole, it is important to use the right tool for the job. A dial bore gage is a tool that is specifically designed for this purpose. There are a few things to keep in mind when using a dial bore gage, and this blog will go over six of the most important things to consider.
- Material: The first thing to consider is the material that the dial bore gage will be used. Different materials require different methods of measurement. For example, if you are measuring the inside diameter of a pipe, you will need to consider the pipe’s wall thickness. If you are measuring the inside diameter of a hole in a piece of metal, you will need to account for the type of metal.
- Accuracy: The second thing to consider is the required level of accuracy. Dial bore gages are available in a variety of accuracies. The higher the accuracy, the more expensive the gage will be. It is important to choose the right accuracy for the job at hand.
- Range: The third thing to consider is the range of the dial bore gage. Different gages have different ranges. It is important to choose a gage with a range appropriate for the task at hand.
- Resolution: The fourth thing to consider is the resolution of the dial bore gage. The resolution is the smallest increment that the gage can measure. The higher the resolution, the more expensive the gage will be.
- Size: The fifth thing to consider is the size of the dial bore gage. Dial bore gages come in a variety of sizes. It is important to choose a size that is appropriate for the task at hand.
- Price: The sixth and final thing to consider is the price of the dial bore gage. Dial bore gages range in price from a few hundred dollars to several thousand dollars. It is important to choose a gage that is within your budget.
There are a few reasons why someone might want to set up a Dial Bore Gauge. The most common reason is to check for wear on the inside of a workpiece. This is especially important in engines, where even a small amount of wear can cause big problems. Another reason for using a Dial Bore Gage is to check for taper in a workpiece. This is where the hole is slightly smaller at one end than it is at the other. This can be caused by poor machining and can cause problems with how the workpiece functions. Finally, Dial Bore Gages can also be used to check for ovality in a workpiece. This is where the hole is not perfectly round and can cause problems with the workpiece’s function.
There are a few different types of Dial Bore Gages. The first and most common is the three-point gage. This is the type of gage that was described in the previous paragraph. The second type of Dial Bore Gage is the two-point gage. This type of gage is used when the workpiece is not perfectly round and can give more accurate readings. The third and final type of Dial Bore Gage is the single-point gage.
