You can clearly understand the technology of grinding! "Thickness Gauge"

[Concern] I want to easily measure the thickness wear.

The height and thickness of items may wear down over time with use, potentially failing to meet the specified sizes and dimensions. However, if the wear is on the micron level (0.001 mm), it is impossible to visually confirm the wear condition. Of course, it cannot be measured with a ruler either. For simple shapes, the following methods can be used for measurement: 1. Measure with calipers (approximate: 0.1 mm unit) 2. Measure with a micrometer (approximate: 0.01 mm unit) 3. Use block gauges for comparative measurement with a dial gauge (approximate: 0.001 mm unit) <Easily Measure> The quickest way is to prepare a dedicated thickness gauge (thickness gauge). Standard thickness gauges are also available for sale, but depending on the shape of the product and the measurement location, it may only be possible to measure partially, or in the worst case, measurement may not be possible at all. By preparing a dedicated measuring instrument (gauge), it is easy to obtain the same quality evaluation results regardless of who measures it. Dedicated measuring tools are specially designed based on product drawings and manufactured according to the design specifications. As an application, it is also possible to measure the width (height, depth, etc.) of grooves.
