Maximize Parts Per Cycle

Run more parts per cycle. Eliminate unnecessary tool changes and rapid moves by running multiple parts per cycle. Reduction of part handling is a big benefit gained by utilizing a horizontal cnc. Modular tombstones further those benefits, by making changeover and setup times shorter and more efficient.

Tombstones of all sizes

We see tombstones as a simplified version of automation. With that said, we designed tombstones for all sizes and types of cnc machines. Our original designs were built for small and medium 4th axis machines. The line has quickly grown to encompass vertical and horizontals up to 500mm.

FAQ

Our tombstones are precision-machined from high-quality cast iron or aluminum, depending on the model. Each unit is designed for rigidity, repeatability, and thermal stability in demanding machining environments.

5th Axis tombstones are compatible with either the 52mm RockLock™ quick-change system or 96mm RockLock™ quick-change system (industry-standard).

Yes, our tombstones are designed to be modular and compatible with 5th Axis self-centering vises and many other industry-standard workholding solutions.

• Cast Iron: Ideal for heavy-duty machining with high stability and vibration damping.
• Aluminum: Great for lighter-duty or high-speed applications where reduced weight and easier handling are preferred.

We offer a variety of sizes (300mm-500mm) including double sided, triple and quad-sided tombstones. Visit the product page for specific model dimensions.

The RockLock™ quick-change system allows you to rapidly swap tombstones or vises with precise repeatability, cutting down setup time and increasing machine uptime.
