AMROK Epoxy-Mineral Tombstones

Advanced Machine & Engineering Co. offers its AMROK brand tombstones in epoxy-mineral material, available in various standard shapes and sizes.

Significant user benefits of this material include vibration damping rated at 10 times that of cast iron and 100 times better than aluminum, measured by logarithmic decrement. These tombstones are lightweight, similar to aluminum and offer very stable thermal expansion characteristics, with low coefficient of linear expansion.

The epoxy-mineral material comprises quartz gravel, silica and crushed rock mixed with a high-quality epoxy resin binder. The finished product has a granite-like appearance.

Originally, epoxy-mineral material was used in the machine tool industry to reduce thermal expansion and vibration in machine bases. Today, it's equally advantageous as a lightweight solution that allows users the ability to utilize the full envelope of the machine.

AME AMROK epoxy-mineral tombstones are available with either molded steel plugs for tapped holes or ½" inner diameter precision bushings with hardened, threaded inserts on a 2" grid.
