Corporate History

August

1980

•Mr. Masayuki Naka, the founder of NAKA SEISAKUSHO, who decided to start up his first own business in sewing machine and bicycle parts processing industry at Yao City Ota 2-chome.

March

1983

•Due to our company had to deal with vessel parts; we therefore adopted NC lathe technology. As the consequence, we had to move our factory to Otashin-machi 8-chome.

September 1988

•With the needs of reproduction parts, so we applied CNC compound lathe and put more focus on machining center basis. As a result, we had shifted our production factory to Otashin-machi 5-chome.

March

1990

•The company had been reformed by setting up as a registered NAKA SEISAKUSHO CO., LTD.; and concurrently, Mr. Masayuki Naka took an office as a company’s president since then.

January

1994

•With the need of firm expansion, we were to import more machines to increase our production capacity; thus, we again had made another step to set foot at Otashin-machi 7-chome.

•Furthermore, we started to employ a computerizing system to control the purchasing, buying, stocking, and also the inventory management in order to achieve a higher efficiency standard.

September 1997

•Owing to an increase in center-less grinding machines and CNC compound lathes, we expanded our land and set up the 2nd factory to increase the production capacity and build up a warehouse.

August

1998

•We decided to go further by moving our manufacturing basement and setting up a new office at Otashin-machi 6-chome where is currently our present head office and factory. Besides, we also expanded company area by opening our 2nd factory nearby. Hence, we are able to put more production machines combining with a distribution warehouse.

July

1999

•To reflect the demand of shafts in servo motor, we thus imported NC cylindrical grinding machines.

October

2004

•Mr. Hideki Naka was invited to take an office of the company’s president.

November 2005

•To follow an increase in numbers of CNC compound lathes, we opened 2nd factory specializing in grinding.



February

2007

•With a rise in demands of construction machine’s components, we moved our production base to the 2nd factory, simultaneously, installing more center-less grinding machines.

October

2007

•An increase in NC compound lathes installed in corresponding to the cut of a large-diameter processing

January

2009

•Received ISO9001 (No. 05454) International Standard Certification

March

2009

•Increase of CNC compound lathes coupled with center-less grinding machines

April

2009

•TESA-VISIO 2D measuring instruments were employed, we thus built up an inspection lab center.

November

2009

•Granted a prize of Osaka Monodzukuri Spirits Excellent Company of Osaka in 2009
