BEYOND THE INDUSTRY STANDARD
AMROK® Tombstones and Fixture Plates are meticulously designed to meet the industry's most stringent tolerances for flatness, parallelism, perpendicularity, surface finish, and hole location. Every Tombstone and grid plate undergoes a rigorous inspection process using AME's in-house Coordinate Measuring Machine (CMM).
MACHINING & CONFIGURATIONS FOR TOOLING COLUMNS
AMROK® precision-manufactured tombstones, tooling columns, and fixture plates meet the highest standards of precision and quality. Our products feature precision tolerances to ensure optimal performance.
With co-axially positioned bushings, our inserts enable precise positioning and clamping in every hole. They offer excellent wear resistance and are easily replaceable, thanks to hardened precision bushings.
We also provide replacement bushings and insert kits, along with an extraction tool, to facilitate any necessary replacements.
