[ Introduction to Equipment Products ]Tool Products (Consumables)
We provide tools that deliver excellent cutting precision and efficiency, tailored to suit a variety of materials. Cutting and dividing conditions can vary significantly due to factors like heat treatment during the manufacturing process. With a deep understanding of these material properties, we offer the most suitable tools. Our commitment to quality is backed by in-house production at our factory in Japan, where we handle everything from development to manufacturing, ensuring a stable supply of the highest-quality tools.
[ Introduction to Tool Products ]Processing Technology for High-Hardness Components
We provide technology for ultra-precise, micro-scale processing of high-hardness components, such as PCD (polycrystalline diamond) and carbide materials. PCD has a lifespan 10 to 100 times longer than other metal components, contributing to reduced production losses and waste. Our fully integrated development and production system at our domestic factory ensures a stable supply of the highest-quality tools. This reduces production losses caused by machine downtime and supports initiatives toward achieving the SDGs.
