TombStone_Cube_Front

AMROK® tombstones, tooling columns and plates are manufactured to the highest precision and quality standards with our precision tolerances.

  • Inserts allow positioning and clamping in every hole with co-axial positioned bushings.
  • Assures high wear resistance & replaceability with hardened precision bushings.
  • Replacement bushings and insert kits with an extraction tool are offered if needed.

Tolerance & Machining Options

Grid

Grid

For maximum flexibility, choose a precision grid. AMROK grids are typically machined to the industry standard 2 inch spacing, but custom spacing is available upon request. Alpha-numeric labeling makes it easy to relocate fixturing components on the grid. Each hole features a hardened threaded insert beneath a precision bushing and can be used for both locating and mounting.
