Why choose Numata Optical?
We offer processing with all types of materials, including aluminum, bronze, stainless steel and steel materials.
We specialize in composite fabrication of bar stock and can fabricate bar stock up to diameters of φ70. Materials ranging from φ71 to φ200 will need to be fabricated individually.
We use 3D measuring equipment to provide precision fabrication services to accommodate orders of 1/1000mm tolerance in terms of roundness, concentricity, parallelism, straightness, flatness, cylindricity, perpendicularity, angularity and accuracy of position and symmetry, etc.
We obtain maximum performance from our processing equipment and work constantly on maintaining and improving our technologies while also retaining a high level of precision to accommodate single product orders right up to mass production. Our ability to reduce equipment set up time and achieve high-yield fabrication is the result of our dedicated pursuit of quality, something that has remained unchanged since our foundation.
As a result, we have maintained a high level of precision and finish in our product quality that some may call excessive. We have remained true to our approach of manufacturing parts that best suit the applications of our clients and their clients further down the consumer chain to reflect our passion towards manufacturing with the aim of providing not only parts for optical equipment, but also technologies for a broad range of fields... This is why people choose the quality of Numata Optical.
Trust borne from our dedicated pursuit of quality.
We have continued to provide parts for precision optical equipment since our foundation and what sets our products apart is more than the precision of their dimensions; it is the attention to detail and the surface finish.
As is characteristic of optics and precision parts, projects from current clients require coaxial processing, parallelism and roundness and we have also received many orders for parts where the external appearance is of crucial importance.
Fabrication services and equipment revolve around “complete composite fabrication” using the CNC lathe. Bar stock up to a diameter of φ70 are processed with one chuck and diameters ranging from φ71 to φ200 are fabricated using a collet chuck.
The main materials we work with include A5056, C3604BD, SUS303, S45C and others such as A2011, SUS304 and SUS420, etc. Having introduced the CNC lathe early in the 1970s, we harness the unique characteristics of this machine to provide fabricated products in a variety of shapes.
