High-Precision Laser Processing Technology

High-Precision Laser Processing Technology

Kyocera offers laser processing, which enables small-lot production using CAD data and the facilitation of high-precision processing. Laser processing can be applied to diverse range of materials.

                    

                    *The image shows an example of processing using a high-precision laser.                     

Features

  • No mold required, allowing prototyping from small quantities
    Since processing can be done by providing CAD data, this facilitates both mold cost and production lead time reduction.
  • Wide range of materials
    We support laser processing for various ceramic materials, allowing you to choose the optimal material with suitable properties for your application.
  • High dimensional accuracy
    Our technology supports post-sintering processing, so it is less susceptible to variations caused by shrinkage during sintering, allowing for high-precision finishes.

Hole Diameter

Inner Diameter
     

・Minimum Hole Diameter
If the plate thickness is 1.0mm or less, a diameter of 0.20mm is achievable (with a tolerance of ±0.05mm).

*We also undertake processing of even finer hole diameters and for plates thicker than 1.0mm. For example, we have experience processing holes of φ0.13mm in a plate thickness of 0.254mm.

・Hole Diameter Tolerance
For plate thicknesses up to 1.0mm, a tolerance of ±0.05mm applies regardless of the hole diameter.
