This department is in charge of manufacturing parts for experimental and observation equipment.

The Machining team, Additive Manufacturing team, and Measurement team work together to support equipment development through fabrication.

Team Overview

Manufacturing team

We use machining centers, milling machines, lathes, electric discharge machines, and various other machine tools to manufacture observational devices and other equipment.

Additive Manufacturing team

We are currently developing applications of additive manufacturing technology for astronomical observational equipment using metal and plastic 3D printers.

Measurement team

We perform precision measurements such as shape measurements of machined parts, position measurements for assemblies, and alignment adjustment of optical equipment.
