Summary of products and technology
[Strong points of our products and technologies] Our nanotechnology production technology center makes use of vibration countermeasures and strict temperature management to create an environment that satisfies demands for higher precision. We have established advanced technologies required for processing workpieces with shapes that are becoming increasingly finer, more complex, and larger. We possess multi-axis (five-axis and six-axis) microfabrication machines capable of processing workpiece of 800 × 800 mm at maximum. We also have an ultra-precision four-axis aspherical processing machine, which is one of the largest in Japan and capable of processing workpieces of up to 700 mm in diameter. We have a full set of measuring instruments for quality control, and offer a reliable warranty program. We also possess special technologies including ellipse vibration cutting and FTS/STS processing. Our core technology is cutting, and we are good at machining difficult-to-machine materials and shapes for automobile parts and aircraft parts, as well as ultra-precision micromachining, which is indispensable for the production of lenses and other products. We have a large number of large 5-axis machining centers and combined lathes. Our jig manufacturing technology, based on our unique know-how, enables high-precision machining of castings in a short period of time. In the field of resin molding, we provide total solutions to customers through our integrated in-house production system, from mold design to manufacturing and injection molding. [Market cultivation and overseas business expansion] We have a large number of transactions with major companies and we plan to expand our business in the future. We have a complete and reliable system for maintaining confidentiality because of the characteristics of our products and services. We plan to improve our system to provide enhanced services to overseas makers.
[Message from the President] We have been working to become a company that pleases customers under a customer-first corporate philosophy ever since our foundation. Our company was founded thirty years ago, and we now have a comprehensive system to support our customers. We will enhance our three unrivaled technologies of optical part processing, nanometer-level processing of fine workpieces, and processing of difficult-to-cut materials. All of our staff members will work together to become a company that satisfies customer needs and continues to be needed by customers.
[Company strength] Our ultra-precision micromachining technologies are indispensable for manufacturing mirror finish and high-precision products, as well as optical lenses, light guide bodies, and other optical components. We have many achievements in the fields of automobiles, smartphones, and medicine because of these technologies. This is done through our integrated operations that cover prototype parts manufacturing as well as design and manufacturing with mass production molds. [Business description] We are a manufacturer that conducts integrated design and manufacturing with support from design models and prototypes. We handle electric and telecommunications devices, auto parts, and optical instrument components, including mold making to injection molding, in addition to ultra-precision micromachining of precision and optical components. [Strength of products/technologies] We created an environment in our nanotechnology production engineering center where we can accommodate needs for higher precision by installing vibration control and rigorous thermal control. We have advanced and established the necessary processing technologies according to shapes becoming more detailed, complicated, or lager. Our equipment includes 5-axis micro-machining tools that process up to 25 inches, and one of Japan’s largest 4-axis aspheric surface processing machines, which processes up to diameter 700 mm. We plan to introduce an ultra-high precision 6-axis micro machine tool in the summer of 2014. We possess various measuring instruments for quality assurance. Elliptical vibration machining, FTS/STS processing, and other special technologies have been established in our company. [Representative's message] Our company conducts the kinds of machining that are difficult for other companies. This is done by using our unique ultra-high precision micromachining technologies that combine the latest technologies and equipment. Our company makes various proposals for advanced development and production worldwide, irrespective of the field, as we aim to cultivate the world market. [Company structure for market development/overseas expansion] We have many dealings with major companies, which are expected to expand in the future. We take all possible confidentiality measures because of the nature of the products we handle. We have a plan in place to further expand our already rich lineup of services for overseas manufacturers. This year we conducted a feasibility study on possible business expansion in China and Taiwan with F/S assistance from SME Support Japan. [Authorization/Certification] Acquired ISO 9001:2008 certification. Acquired JIS Q 9100:2016 certification. [Joint research and development] Our research on creating innovative titanium alloy processing technology is subsidized by NICO (Niigata Industrial Creation Organization) as part of their support for advancing the regional technological base.
