Achieving high precision of 2μm or less for right angles and straightness up to 1000mm! Easy and reliable comparative measurements can be performed on the manufacturing floor!
The ceramic square master utilizes the characteristics of ceramics such as "excellent rigidity and resistance to warping," "hardness and excellent wear resistance," "minimal dimensional changes due to temperature," "excellent corrosion resistance and strong against chemicals," and "lightweight," ensuring precision in perpendicularity and parallelism down to the micrometer level. It is ideal for ensuring assembly accuracy in machine tools, measuring motion accuracy in three-dimensional measuring machines (straightness and perpendicularity), and measuring the straightness and perpendicularity of high-precision parts. 【Features】 - Size: Up to 1000mm, achieving high precision of perpendicularity/straightness below 2µm! - Lightweight and easy to measure, making it easy to carry! - Due to its high rigidity, it has minimal deflection from its own weight and excellent wear resistance (Young's modulus of 380 GPa). - Minimal deformation due to temperature changes, making it less susceptible to environmental influences during measurement! 【Highly rated by customers】 - There is no change in accuracy, providing confidence in measurement results. - Measurement has become easier compared to metals and stones. - Dirt is more noticeable, prompting operators to be more conscious of 5S practices. - It has a luxurious feel with its white color.

Company information
At Shin-East V Ceramics, we leverage the properties of ceramics to provide new added value through our unique technology. We have achieved significant results and high trust across various fields, from components for manufacturing and inspection equipment, including semiconductors, LCDs, and electronic components, to ultra-precision measuring instruments such as straight edges and right-angle masters, as well as ceramics application products like XY stages. Additionally, with the sale of ceramics 3D printers, it has become easier to commercialize complex shapes that were previously difficult to handle, as well as hollow structures for weight reduction and enhanced functionality. This has led to adoption in a wider range of fields and industries, from aerospace to biomedical sectors.
