When measuring a product, the measuring instrument is selected based on the dimensions and tolerances specified in the product drawing. However, there are many types of measuring instruments available in the world. For example, even when considering instruments for measuring "length," there are various types such as scales, calipers, micrometers, comparative measuring instruments using dial gauges, three-dimensional measuring machines, projectors, and more, making careful selection necessary. Therefore, I would like to explain the points to consider when selecting the appropriate measuring instrument from the wide variety available. [Excerpt of Content] ■ Points to consider when selecting a measuring instrument - Choose a measuring instrument according to the required accuracy for the measurement. - Consider the characteristics of the object being measured (shape and material). - Take into account the ease of measurement and the acceptable measurement error. - Consider cost performance. - Consider the ease of maintenance. *For more detailed information, please refer to the related links.

"Comparative measurement" refers to measuring the characteristics or properties of a subject by comparing it with a reference value or standard material. For example, in the measurement of "length," one might measure both a reference piece, such as a block gauge, and the subject simultaneously using a dial gauge, and determine the length of the subject from the difference. In general, measuring instruments used for "comparative measurement" are referred to as "comparative measuring instruments." Our company primarily handles measuring instruments for measuring "length," particularly those for measuring "inner diameter," "outer diameter," "height (width)," "chamfering," and limit gauges. 【Contents】 ■ What is a comparative measuring instrument? ■ Features of comparative measuring instruments *For detailed content of the article, please refer to the related links.

When measuring using a "comparison measuring instrument," the process involves comparing it with a "master gauge" (reference gauge) such as a ring master or block master that has been prepared in advance according to the dimensions of the measurement area, and determining the difference from the reference gauge. As explained here, the "master gauge" (reference gauge) is used to perform the "master adjustment (zero adjustment)" of the dial gauge. "Master adjustment" refers to the task of aligning the needle of the dial gauge to zero using a master gauge that serves as a reference for the measurement dimensions.

The term "calibration" in "calibration of measuring instruments" is defined in "JIS Z 8103:2019 Measurement Terms." In short, "calibration" refers to the process of checking how much the indication of the measuring instrument being calibrated deviates from that of the reference measuring instrument, and it involves explicitly stating the uncertainty as a measure of its reliability. 【Contents】 ■ What is calibration of measuring instruments ■ Calibration of master gauges (reference gauges) *For detailed content of the article, you can view it through the related links.

"Geometric characteristics" are classified in ISO/JIS according to the applicable shapes and types of geometric tolerances. A "datum" can be simply defined as "the dimension that serves as a reference during measurement." When specifying the geometric tolerances of related shapes in a drawing, the reference axes, surfaces, and dimensions are designated with letters of the alphabet, and these letters are referred to as datums. To correctly evaluate the "geometric characteristics" and "geometric tolerances" listed on product drawings, it is necessary to understand their meanings accurately and choose appropriate measurement methods accordingly.

Roundness is one of the geometric tolerances applied to a single shape, referring to "the magnitude of deviation from the geometric circle of the circular part." Methods for measuring roundness include roundness measuring machines (such as Roncom), reading methods using center support, and three-dimensional measuring machines. A practical measurement method involves measuring the diameter with a dial gauge, and the Kensatools roundness measuring device falls into this category.

Concentricity and coaxiality are positional tolerances applied to related geometric shapes. Coaxiality refers to "the magnitude of deviation of the axis line that should be on the same straight line as the datum axis line from the datum axis line," while concentricity refers to "the magnitude of deviation of the center of another circular shape relative to the center of the datum circle in the case of planar shapes." Measurement methods for concentricity and coaxiality include roundness measuring machines, center support or V-block reading methods, and three-dimensional measuring machines. 【Contents】 ■ About concentricity and coaxiality 1) Definitions and illustrated examples 2) Tolerance zones (allowable ranges) 3) Measurement methods ■ Thickness measuring instruments *For detailed content of the article, please refer to the related links.

The "Master Ring/Master Block" refers to a reference gauge (master gauge) used for measurement with comparative measuring instruments. The ring-shaped ones for inner and outer diameters are called master rings, while the block-shaped ones for height and width are referred to as master blocks. Incidentally, the method of measurement that seeks the difference from this reference gauge is called comparative measurement. 【Master Ring Specifications】 ■ Measurement Locations: Outer Diameter, Inner Diameter ■ Measurement Range (Approx.): Φ5 to Φ200 ■ Dimensions (Approx.) - Inner Diameter: Φ5 and above - Outer Diameter: Up to Φ200 - Width: 10 to 20 *For more details, please refer to the PDF document or feel free to contact us.

The "Geometric Characteristics Measurement Device" is a product designed to measure geometric characteristics. The device uses a dial gauge for measurements and includes a pitch gauge for measuring positional accuracy, eliminating the need for a reference master required for comparative measurements. Geometric characteristics refer to the properties that regulate "shape, posture, position, and runout" (according to JIS Z8114 "Drafting - Drafting Terms"). Geometric characteristics are classified into shape characteristics, posture characteristics, position characteristics, and runout characteristics. 【Classification of Geometric Characteristics】 ■ Shape Characteristics: Roundness, Flatness, Cylindricity, etc. ■ Posture Characteristics: Parallelism, Perpendicularity, etc. ■ Position Characteristics: Positional Accuracy, Concentricity (Uneven Thickness), Coaxiality, etc. ■ Runout Characteristics: Circular Runout, Total Runout *For more details, please refer to the PDF document or feel free to contact us.

The "Comparative Measuring Instrument" is a product that measures dimensions such as inner diameter, outer diameter, and height by comparing them with reference gauges (master gauges) such as ring masters or block masters that are prepared in advance to match the dimensions of the measurement area, and calculates the difference from the reference gauge. When comparing, a dial gauge is used to obtain the difference from the reference gauge in numerical form, and it is classified into measuring instruments (such as "inner diameter measuring instrument," "outer diameter measuring instrument," "height measuring instrument (flat stand)," and "chamfer measuring instrument") that determine through comparison and "limit gauges" that determine through go/no-go. Measurements with comparative measuring instruments are easy and the measurement error can be kept small, making them commonly used in cases of mass-produced items where repeated measurements are necessary. 【Lineup (partial)】 <Inner Diameter Measuring Instruments> ■ASQA-ID-01 ■ASQA-ID-02 ■ASQA-ID-03 ■ASQA-ID-BMD <Outer Diameter Measuring Instruments> ■ASQA-OD-01 ■ASQA-OD-02 *For more details, please refer to the PDF document or feel free to contact us.
