Q1: What is a dial bore gauge?
A1: A dial bore gauge is an instrument that measures the inner diameter of small holes. Bore gages are critical when it comes to measuring parts that have small holes in them. Typically, these versatile instruments are used as part of a quality control process to ensure that bore sizes are standardized.
Q2: Why is a bore dial gauge used?
A2: A Bore Gage is used to measure the inside diameter of a hole or cylinder. This explains why it is referred to by so many different names. You are actually measuring the bore size.
Q3: How does a dial bore gauge work?
A3: A typical bore gauge is comprised of a shaft with a dial indicator at the top and a measuring sled at the base. The measuring sled consists of three guides and an actuating plunger. Dial bore gauges give you quick and accurate readings on the size, less than perfect roundness or wear.
Tips: How to use the dial bore gauge?
The dial bore gauge is used to measure cylindrical holes, and it is attached with a set of adjustable measuring heads, which must be combined and zero-checked before use. Before the measurement, the size should be adjusted with the outer diameter micrometer according to the size of the measured aperture before use. When adjusting the size, the length and extension distance of the interchangeable probe should be correctly selected so that the measured size should be in the middle of the total movement of the movable probe.
When measuring, the centerline of the connecting rod should be parallel to the centerline of the workpiece, and should not be skewed. At the same time, several points should be measured on the circumference to find out the actual size of the aperture and see if it is within the tolerance range.
