StrengthsDIGITAL × CRAFTMANSHIP
Digital x Craftsmanship
The power to shape precision technology and subtle nuances.
We leverage the comprehensive strengths—'hardware' (technology) and 'software' (expertise)—cultivated through eyeglass frame manufacturing to enter the medical surgical instruments business.
For hardware, We utilize 5-axis machining centers to mill difficult-to-process titanium with micron-level precision. Laser welding minimizes thermal impact, achieving strong, delicate joints. This digital-based high-tech processing foundation in our domestic factories accurately reproduces the precise shapes required by surgeons.
For software, We have pursued the unquantifiable factor of "wearing comfort" for years. Applying this expertise, the "human touch" refines aspects beyond pure numbers: a comfortable grip, smooth articulation, and operability that transmits intended forces—the subtle "nuances" of the instrument.
"Digital x Craftsmanship" is the integration of cutting-edge technology and master craftsmanship (Takumi skill) that brings the surgeon's ideals to life. It represents a new approach to manufacturing that supports surgery by leveraging the precision technology from our original eyewear business. This is our core strength.
Fabrication
The tip of the Inamura Capsulorhexis Forceps has serrations with a width of 0.08 mm (80 µm). This is narrower than the average human eyelash (0.10 to 0.15 mm).
This delicate shape is achieved using a 5-Axis Machining Center (5-Axis MC), a high-precision cutting machine.
Assembly
Laser Welding
Compared to arc welding, our laser welding concentrates high energy, resulting in an extremely small heat-affected zone.
This allows for joining with minimal area, preserving the material's composition and minimizing heat-induced deformation or deterioration, ideal for micro-components.

Laser Fusion
Screws are used at instrument pivot points. Traditional peening (crushing the screw tip by force) risks variability (too tight/loose).

- After laser
- After finishing
We use laser welding for condition-controlled fastening to eliminate this inconsistency.
Laser Anti-Slip Processing
We apply laser technology, utilizing our engraving expertise, for anti-slip processing (Cross MAX).
This is ideal for delicate texturing on thin products or for surfaces that must grasp fine objects without cutting them—something difficult to achieve with traditional cutting tools.

Finishing
Production is managed via tablets to control progress and ensure on-time quality. Staff competencies are evaluated according to ISO 13485:2016, and assignments are based on skill.
Quality is assured by strict adherence to Standard Operating Procedure and stage-specific inspection checklists. Our manufacturing goal is not handicrafts dependent on individual skill, but high-quality industrial products where machine processing and human expertise collaborate. We maintain the systems and environment to consistently deliver uniform, reliable products.
