July•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.

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

•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 toOtashin-machi 5-chome.
•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 sincethen.
•With the need of firm expansion, we were to import more machines to increase ourproduction 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.
•Owing to an increase in center-less grinding machines and CNC compound lathes, weexpanded our land and set up the 2nd factory to increase the production capacity andbuild up a warehouse.
•We decided to go further by moving our manufacturing basement and setting up a newoffice at Otashin-machi 6-chome where is currently our present head office and factory.
Besides, we also expanded company area by opening our 2 nd factory nearby. Hence, we
are able to put more production machines combining with a distribution warehouse.
•To reflect the demand of shafts in servo motor, we thus imported NC cylindrical grindingmachines.
