Heiwa Technica Co., Ltd. "Precision Cutting Wheels" Comprehensive Catalog

Heiwa Technica Co., Ltd. "Precision Cutting Wheels" Comprehensive Catalog

We have a wide range of cutting wheels available!

Processing with precision cutting wheels involves the use of high-speed rotating cutting wheels that are extremely thin (0.3mm to 1.2mm). This method is a type of precision machining that gradually shaves the workpiece using very hard particles (grains) that make up the wheel. It acts softly without causing destructive damage to the workpiece, resulting in a good surface finish, sharp cutting performance, and excellent grinding capabilities, boasting high-speed cutting that contributes to the reduction or elimination of secondary processing, thus lowering costs. The Precision Cutting Wheel Tokuwu Stone Series is manufactured under strict quality control in the Nasu factory, located in Nasu Town, Tochigi Prefecture, where temperature and humidity are kept constant to maintain stable quality on the production line. The Diamond Cutting Wheel Naston Gold Series for hard and brittle materials is a developed product made using high-quality diamond grains and a unique resin. It demonstrates its power in cutting hard and brittle materials such as cemented carbide, ceramics, hard glass, and sapphire glass, as well as difficult-to-machine composite materials, which are challenging to cut with general cutting wheels.
