Takezawa Seiki Co., Ltd.

Our diamond reamer prolongs the operating life of tools with 0.5 μm-accuracy of circularity.

We now manufacture our own independent diamond reamer products, honing machines, and other large-scale components. Our diamond reamers facilitate finishing processing with difficult-to-cut materials such as cast iron. Their characteristics include 0.5-μm circularity, 0.5-s surface roughness, excellent wear resistance, and four times the durability of ordinary grindstones.
