Traditional techniques shine! "Template"

[Concern] I want to create or repair a high-quality whetstone molding template.

<Template> Templates are used to shape general grinding wheels for grinding machines. A profiling dressing device traces the template, and a grinding wheel with a shape that is 1/N times that of the template is formed. This is an old-fashioned processing method, but there are still cases where it is actively used. <Manufacturing> The quality of the template directly reflects the shape of the grinding wheel being formed, so high quality is required for the template. Specifically, flatness of 1 micron (0.001 mm) and step tolerance at the 1-micron level are standard. <Quality Assurance> Since the required precision of the template is at the micron level, it is necessary to measure the template itself accurately. This measurement is done through comparative measurement with block gauges. A precise dial gauge known as a dial indicator is used for comparative measurement. Additionally, since the profiling dressing device traces the same spot on the template multiple times, specific areas can wear down significantly. Therefore, it is necessary to check for wear after long-term use of the template. <Repair> Generally, templates often require relative step differences, and repairs are possible if they become worn. Typically, repairs can be done at about 70% of the cost of a new one.
