Automatic machining of curved surfaces 43 MC units and a diversity of human resources

(Nihon Butsuryu Shinbun dated July 10, 2008)

Nihon Butsuryu Shinbun's "Challenge! Machining Factory Site" featured Nagai Seiki's automatic machining of complex three-dimensional curves by actively promoting capital investment mainly for machining centers (MC) and developing engineers with diverse skills. The newspaper article highly evaluated our approach to hiring a diverse range of human resources stating: "The company is promoting automation and has introduced unmanned, 24-hour operation for most of its machine tools, and even without a shift-work system, it has achieved a monthly running time of 720 hours. But, its most unique feature lies in its policy of securing human resources."

at the Hanover Messe.

(Gunma Keizai Shimbun, December 6, 2007)

At NAGAISEIKI we give full play to our technology when machining turbine blades. In order to publicize our technology to the world with a view to opening up new markets, we intend to exhibit our products at the Hanover Messe in April 2008. The Gunma Keizai Shimbun, a local newspaper, reported as follows: "AGAISEIKI, a manufacturer of gas turbine blades for nuclear power plants and thermal power plants, will exhibit its products for the first time at "Hanover Messe 2008" the world's largest industrial technology trade fair, which will be held in Hanover, Germany in April of next year."

Meeting increased demand by establishing an automatic grinding system

(Gunma Keizai Shimbun, October 18, 2007)

NAGAISEIKI, one of Japan's small-to-medium manufacturers which are often said to "not make a profit yet be busy", is aiming to carry out world top level rationalization. Since the abrupt occurrence of the economic slump due to the high yen in 1985, we have been promoting a changeover to a capital intensive type of business form, and have realized 24-hour unmanned operation of our machining centers for cutting work. At present, we are widening the machining range by placing more emphasis on grinding rather than cutting, and are striving to establish an automatic grinding system using an intelligent robot.

Increased production of blades for power plants

(Nihon Keizai Shimbun, April 12, 2007)

Our efforts aimed at meeting the increased demands for turbine blades by purchasing additional machining centers were mentioned in the Nihon Keizai Shimbun. According to this newspaper, "NAGAISEIKI (Takasaki City, Gunma Prefecture, President: Hidetaka NAGAI), a manufacturer of turbine blades for power plants, is increasing its production of blades in a facility adjacent to the Head Office. The company has invested approximately 34 million yen in the purchase of two machines for cutting blades, and will increase its monthly production volume by about 5% to approximately 7600 blades in order to meet the large demand from the US and China."

Participation in the business of manufacturing blades for blast furnace blowers for steelworks

(Gunma Keizai Shimbun, January 25, 2007)

Based on our turbine blade machining technology developed over many years, we are also putting efforts into developing new markets, and have succeeded in acquiring orders for blades for blast furnace blowers for steelworks. According to the Gunma Keizai Shimbun, "NAGAISEIKI has successfully obtained orders for turbine blades via manufacturers of heavy electrical equipment. The company will supply between 4000 and 5000 blades to major steel manufacturers, and also intends to promote its products among other steel manufacturers as well."
