  • 3D machining

  • Multi-process machining

  • Post-assembly processing

Microfabrication

Yasojima has processing environments and equipment to handle micron-level dimensional and geometric tolerances, as well as an inspection system for conducting precision inspections to ensure that your requirements are met.


  • Microfabrication

Microhole machining

Processing conditions are optimized to suit the characteristics of the material to be processed, and processing is carried out in a temperature- and humidity-controlled environment with anti-vibration measures in place.


  • Microhole machining

Freeform machining

We use our five-axis machining center to produce a variety of shapes to ensure that your processing requirements are met.


  • Freeform machining

Welding/bonding (PEEK)

We provide high-precision welding and bonding for PEEK, which boasts excellent heat, chemical, and wear resistance.


  • Welding/bonding (PEEK)

Roughness control

Yasojima utilizes machining, lapping, and polishing technology to produce optimum surface finishes for both curved and flat surfaces using processing technology developed in cooperation with university research institutions.
