It can reduce temperature correction errors and be used for high-precision calibration work!
The "Gauge Block with Coefficient of Thermal Expansion" is a product that exceeds Class K and comes with a high-precision value for the coefficient of thermal expansion. It can minimize temperature correction errors and is suitable for high-precision calibration work. The coefficient of thermal expansion is measured using a high-precision dual-surface interferometer (DFI), and the dimensions are measured with a high-precision gauge block automatic optical wave interferometer (GBI). It is also used for the calibration of high-precision three-dimensional measuring machines. 【Specifications (Excerpt)】 ■ Nominal dimension standard: Class K JIS/DIN/ISO ■ Uncertainty of the coefficient of thermal expansion: 0.035×10^-6/K (k=2) ■ Uncertainty of the central dimension: 30nm (k=2) (at 100mm) *For more details, please download the PDF or feel free to contact us.

Company information
Suzusho Co., Ltd. was founded in 1955 as a metalworking company in Nakatsugawa, Gifu Prefecture. Later, it also started operations as a machinery and tool trading company, embarking on a genuine journey closely connected to the local community and manufacturing industry. As the industrial landscape of Nakatsugawa evolved, the company continued to grow and develop, and now, as a "comprehensive trading company for production technology," it has built a solid track record throughout Gifu Prefecture and the southern Shinshu/Kiso area of Nagano Prefecture. With our reliable experience since our founding, we are committed to supporting local communities and, by extension, Japan's manufacturing industry with safety and trust, continuing to grow together with our customers.
