Since the foundation in 1936, we have pursued the limit and possibility of precision. TAKAHIRO provided a lot of customers with high quality parts and products through the research and development of original technology.
In order to answer the higher, more diversified request from the global market, TAKAHIRO will continue to develop more advanced technology and product.
TAKAHIRO started the business by setting one grind machine in 1936. Overcoming the chaos of WWⅡ, we expanded the process field to heat treatment and machining. With the processing technology, we developed a high precision indexing unit "Soarerdex" with roller gear system. Recently we advanced it to the merchandise "Roller turn" (NC rotary table) that many our customers utilize in factory automation.
In the long history of 80 years or more, we have been supported with so many customers. Appreciating it, we will also make a progress keeping in mind the frontier spirit of "Do what no one do" that was 2 founders bore when they began grinding business where there was no grinding company in Nagoya.
