President message

Since the company foundation as a grinding works in 1936, we have been engaged in grinding technology and produced various parts. Overcoming the chaos after World War Ⅱ, we expanded our business to the process of heat treatment and machining, now we have become a total process manufacturer. Making use of these technologies, we have originally developed “SoarerDex”, a roller gear unit. The products were used by a lot of customers in the market of the factory automation. Lately we have developed an NC rotary table “ROLLERTURN” in the trend of “non backlash” rotary positioning.
Since the foundation, TAKAHIRO have been blessed with a lot of customers and business. We will create good products and contribute customers and society to the future.
