We will be exhibiting at the "High-Performance Materials Week 2018, 3rd High-Performance Ceramics Exhibition"!

From material selection such as ceramics, quartz glass, and high melting point metals to cooperation in new product development, you can rely on us for precision processing of hard and brittle materials.

We perform grinding, cutting, and polishing of various ceramics, quartz glass, and difficult-to-machine materials such as tungsten and molybdenum. With the motto "If it can be processed in iron, there is nothing that cannot be processed in other materials," we have accumulated technology over the years. We primarily use machining centers, owning over 70 three-axis machines and more than 15 five-axis machines, as well as ultra-high precision machines with linear specifications. Additionally, we have a comprehensive range of measuring equipment, including three-dimensional measuring machines, image measuring instruments, and laser microscopes. We have established a quality assurance system, and we can perform cleaning and drying in a clean room, as well as vacuum packaging. Even if there is little experience with ceramics or high melting point metals, we consider factors such as heat resistance, low expansion, high hardness, wear resistance, and electrical insulation to select and propose materials that meet your requirements. If you have new materials or are struggling with processing materials, please feel free to consult with us. 【Business Activities】 ○ Processing and sales of various ceramics and brittle materials such as quartz glass ○ Processing and sales of high melting point metals such as tungsten and molybdenum ● For more details, please download our catalog or feel free to contact us.

Here are examples of processing quartz glass, which can be processed more efficiently than ceramics.

We will introduce examples of processing quartz glass and heat-resistant glass. Quartz glass is softer and can be processed more efficiently than general ceramics. The main point of caution in processing is its fragility, so our company aims to minimize damage to the material during processing as much as possible. Specifically, this involves managing the wobble of the grinding wheel, using high-grit diamond particles, sharp diamond particle shapes, and soft bond grinding wheels. 【Processing Example】 ■Product Name: Shower Plate ■Material Used: Tempax ■Processing Method: MC Processing ■Size: φ2.0, 2,000 holes ■Application: Gas introduction for various manufacturing equipment For more details, please refer to the catalog or feel free to contact us.

[Lecturer] Kazuhisa Yuki, Professor, Department of Mechanical Engineering, Faculty of Engineering, Yamaguchi University of Science and Technology [Key Lecture Content] Currently, the world is facing a serious energy crisis and environmental issues. Particularly, due to the rapidly growing highly information-oriented society, the power demand of global AI data centers is expected to double from the 2024 level, surpassing Japan's total electricity consumption. In the future, to achieve a rich highly information-oriented society while maintaining carbon neutrality, securing a cheap and stable power supply is essential, and energy conservation in data centers will become the most important challenge. Against this backdrop, two-phase liquid immersion cooling technology, which can significantly reduce power input associated with cooling while achieving high cooling performance, is attracting attention. In this lecture, we will discuss efficient cooling technologies for data centers, evaluated based on cooling performance (air cooling/liquid cooling/liquid immersion technology), and outline the potential and technical challenges of liquid immersion cooling technology in particular.
