Target Range of R-bend Shape

  • The R-bend shape is subject to FR bending (feed bending), which will result in die marks. Please refer to “Bending Specifications” for details.
  • *If you would like to request R-bending processing without leaving die marks, please write it in the comment column for manual quotation.

  • *1 The plate thickness tolerance is ±10% (reference value).
  • *2 The maximum and minimum dimensional values are limited by the shape of the bend.
  • *3 Select a paint color from the table (Appendix Table).
  • *4 The maximum length and width dimensions (Appendix Table) may vary depending on the surface treatment.
  • *5 The machining surface will not be plated as it is a pre-treatment material.
  • *6 Protective sheets (one-side only) affixed.
  • *7 See figure below for hole diameter and hole pitch standards.
  • However, the hole pitch orientation can be set to any value.
