2010
"Best Technical Award" is granted to our HI-GRIND 2 model by the "Association to recognize historic valuable machine in Japan" in the 12th meeting, June 9, 2010.
Award To Our HI-GRIND 2 Model By The "Association To Recognize Historic Valuable Machine Tools In Japan"
"Best Technical Award" is granted to our HI-GRIND 2 by the "Association to recognize historic valuable machine in Japan"(Managed by NIPPON INSTITUTE OF TECHNOLOGY & MUSEUM OF INDUSTRIAL TECHNOLOGY : Sponsored by Ministry of Economy, Trade and Industry, The Japan Society of Mechanical Engineers, The Japan Society of Abrasive Technology, The Japan Society of Precision Engineering) in the 12th meeting, June 9, 2010. Awards by the association are given to machine tools contributed to the development of industry in Japan by their epoch making technology. As a Centerless Grinding Machine, HI-GRIND 2 is the first model awarded by them. HI-GRIND 2 model, awarded is developed to aim higer accuracy, higher productivity and longer life time by full use of hydrostatic oil bearings. After exhibiting the first machine to the 5th JIMTOF in 1970 and starting sales, this model has received high estimation from wide area of users, such as Bearing Industry, Micro Shaft Manufacturers and Auto Motive Industry.By adding improvements and remodeling to meet the higher needs of users, this model is still adding sales achivement as the base model of HI-GRIND Series centerless grinders which have over 2,000 units actual sales.
