BEYOND THE INDUSTRY STANDARD
AMROK® Tombstones and Fixture Plates are designed to hold the industry's tightest tolerances for flatness, parallelism, perpendicularity, surface finish, and hole location. All Tombstones and grid plates are built and then inspected using AME's in-house Coordinate Measuring Machine (CMM).
MACHINING & CONFIGURATIONS FOR TOOLING COLUMNS
AMROK® tombstones, tooling columns, and fixture 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 and replaceability with hardened precision bushings.
- Replacement bushings and insert kits with an extraction tool are offered if needed.
