Manufacturing of precision parts for the space industry
From Higashi-Osaka to Space. Bringing our "problem-solving capabilities,"
cultivated through the annual production of 80,000 custom parts, to the space industry.
Precision parts manufacturing for the space industry
We handle the machining of difficult-to-cut materials such as Inconel, titanium, and Hastelloy, and can produce parts from a single unit.
We already have a proven track record of applications ranging from rocket piping to hydrogen engine components.
Our JIS Q 9100 management system eliminates development bottlenecks.

Micron-level high-precision machining
Our company's origins lie in the manufacture of precision mold parts where every micron counts. We achieve dimensional tolerances on the micron order, which are difficult to achieve with conventional machining, as well as complex-shaped parts with stringent geometric tolerances, through our skilled grinding and electrical discharge machining techniques. We bring the advanced design requirements of the aerospace industry to life.
Prototype production and integrated manufacturing starting from a single unit.
We have established an integrated in-house production system that covers not only cutting using lathes and machining centers, but also grinding, electrical discharge machining, and even heat treatment and surface treatment. By eliminating transportation losses between processes, we can immediately respond to "custom prototypes starting from one unit" from space ventures and research institutions where development speed is crucial.
Capability to handle difficult-to-machine materials
We have extensive experience in machining difficult-to-cut materials widely used in the aerospace industry, such as Inconel, titanium, Hastelloy, and stainless steel. Even with materials that are difficult to machine due to their high hardness and viscosity, we achieve high precision and stable parts supply through optimal tool selection and a database of machining conditions.
Thorough inspection and measurement system
We are equipped with state-of-the-art inspection equipment, including 3D measuring machines and image-based dimensional measuring machines. Experienced inspectors conduct rigorous measurements in temperature-controlled inspection rooms. We also handle geometric tolerance measurements and issue mill sheets (material certificates) and inspection reports, guaranteeing aerospace-grade quality.
Proven track record of deliveries to space development organizations and major heavy industry manufacturers.
Since 2025, we have begun supplying rocket piping components (fluid control and valve-related) and hydrogen engine components (titanium processing) to domestic space development organizations and major heavy industry manufacturers. Our technology is used in areas where micron-level precision and rigorous quality control are essential, such as fluid control components that require reliability under cryogenic and high-pressure environments, and combustion system components that use difficult-to-machine materials such as Inconel.

Regarding the inspection system and traceability
POINT 01
State-of-the-art measuring equipment and rigorous calibration control.
In a temperature-controlled constant-temperature inspection room, skilled inspectors conduct inspections using various measuring instruments. We possess a diverse range of measuring instruments, including 3D measuring machines, image dimension measuring machines, shape measuring machines, roundness measuring machines, and various gauges, enabling us to measure geometric tolerances of complex-shaped parts. The inspection equipment we use is regularly calibrated to ensure traceability to national standards. Furthermore, we implement stable quality assurance under a quality management system compliant with ISO9001 and JIS Q 9100.
coordinate measuring machine
We have introduced a high-precision CNC three-dimensional measuring machine manufactured by Mitutoyo to measure products with complex shapes and strict tolerances.
With a resolution of 0.1 μm (0.0001 mm) as the minimum display unit, it accurately measures dimensional and geometric tolerances (roundness, coaxiality, flatness, etc.) on the "micron order," which are essential for aerospace components. Furthermore, it has a wide measuring range of 700 mm on the X and Y axes and 600 mm on the Z axis, enabling high-precision measurement of a wide range of sizes, from small precision parts to medium-sized housing and casing components.
Image dimension measuring machine
We have introduced Keyence's state-of-the-art image-based dimensional measuring machine, which allows for instant measurement of even complexly shaped parts simply by "placing" them on the machine. This enables measurements that physically eliminate variations in measurement values (individual differences) caused by inspectors.
Furthermore, measurement data is digitally recorded and used for inclusion in inspection reports and trend management (SPC), ensuring complete traceability.
Shape measuring machine
Surface roughness measuring machine
We measure and analyze "surface roughness" and "contour shape" with high precision. Using Mitutoyo measuring instruments, we not only manage surface roughness (Ra, Rz, etc.) numerically according to JIS/ISO standards, but also accurately trace minute corner radii, screw tooth profiles, and complex curve shapes that cannot be captured by 3D measuring machines.
Roundness measuring machine, etc.
Measuring Microscope (Mitutoyo):
Allows magnified observation of minute burrs, sharp edges, and cracks invisible to the naked eye.
Clearly captures the finish of machined surfaces and tool marks, guaranteeing strict appearance quality.
Hardness Tester:
Measures hardness (HRC, etc.) after heat treatment. Instantly determines in-house whether the mechanical properties of the material meet specifications, guaranteeing strength.
3D Scanner:
Supports shape evaluation of complex free-form surfaces and reverse engineering from physical objects without drawings. Visualizes deviations from CAD data using a color map, verifying overall distortion.
POINT 02
