Company Overview

Since our founding in 1977, we have consistently sourced and sold diamond and CBN superabrasives from the former Soviet bloc, South America, the United States, Europe, and China for nearly 50 years, always tailoring our offerings to the needs of the times and our customers.

In recent years, the world of superabrasives has undergone significant changes, and the rapid expansion of the market share held by Chinese-made abrasives has been particularly striking. We began handling Chinese-made superabrasives in 1999. We have continued to conduct on-site audits, including quality inspections, and have worked closely with manufacturers to ensure the quality that satisfies our Japanese customers.

In March 2011, we signed an exclusive distribution agreement in Japan with Famous Co., Ltd. in Henan Province, China, a global leader in the manufacture of resin-bonded diamond abrasives. Since 2012, we have progressively introduced equipment such as electron microscopes, stereo microscopes, laser diffraction particle size analyzers, and micro-Raman spectrometers at our headquarters. We are enhancing our in-house incoming inspection processes to achieve the “optimal quality” that gives our customers peace of mind.

Moving forward, we aim to be more than just a trading company; guided by the motto of “optimal quality,” “reasonable prices,” and “stable supply”—all from the customer’s perspective—we strive to become the No. 1 supplier of superabrasives.
