FAQs

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 maintain a dial bore gauge?

Indication error and adjacent error

  1. Use the dial indicator calibrator for the inner diameter dial indicator with positioning bridge, install the dial indicator on the meter frame, and compress the dial indicator head for one circle, (at this time, the pointer should be pointing at the distance from the axis of the measuring rod. 0.1mm from the upper left), clamp the dial indicator with the locking device. Install the inner diameter dial indicator on the dial indicator calibrator, turn the micrometer head to compress the movable measuring head to the starting point of the working stroke, and adjust the dial indicator to the zero position. Then rotate the micrometer head at intervals until the end of the working stroke. The difference between the maximum value and the minimum value of each point error obtained from the measurement is the calibration result of the indication error; the maximum value of each adjacent error is used as the calibration result of the adjacent error.
  2. The inner diameter dial indicator of the expansion spring type and steel ball type is measured with a dial indicator calibrator. Install the dial gauge on the dial stand, compress it once, and install the inner diameter gauge on the dial gauge calibrator. Measurements are made in the direction of travel of the compression probe. If the working stroke of the probe is less than 0.5mm, measure point by point at an interval of 0.05mm; if the working stroke of the probe is ≧0.5mm, measure point by point at an interval of 0.1mm until the end of the working stroke.
