Tombstones
Tombstones that provide a reliable choice for precision workholding in demanding applications.
Machine Tool Ecosystem
CNC machining foundations custom engineered for more throughput, tighter tolerances
Get tighter tolerances, faster setups and more uptime with Hennig's CNC tombstones, gridplates, and other foundations. Each foundation is machined to industry standard tolerances creating repeatability in your high-mix or high-volume workholding operation – and we do it faster. Quick-response tombstones ship in just two or three weeks.
FLOW BREAKERS
Tired of fighting workholding limitations that slow your operation?
When workholding is not matched to your parts, machine, or production goals, setup time grows, repeatability suffers, and throughput becomes harder to sustain. The right foundation does more than hold a part in place — it supports tighter tolerances, faster changeovers, better machine utilization, and a stronger path toward scalable productivity.
Setup delays that reduce machine uptime
Poor repeatability that affects part consistency
Tolerance variation that creates quality risk
Limited workholding flexibility for high-mix production
Slow fixture turnaround that delays production plans
Workholding constraints that make future automation harder

Tombstone Testing for Dynamic Performance
Because tombstones support the workpiece during machining, their dynamic response becomes part of the entire system. The goal of this effort was to measure the dynamics individually and then as part of a machine setup.
Machine Tool Ecosystem
Why Hennig
Hennig brings together workholding expertise, application-driven engineering, and broader machine tool ecosystem support to help manufacturers get more from every machine. Our approach is built around the realities of your parts, tolerances, and production goals — delivering solutions that improve uptime, increase consistency, and create a stronger foundation for future upgrades like automation, coolant systems, and other auxiliary technologies.
Improve performance now. Build for what’s next.
You’ve got big plans for your future operation, but you may not be able to realize them all right now. Building out a complete system-engineered ecosystem delivers immediate performance gains through well-matched components, while enabling phased upgrades. This allows you to:
- Eliminate costly upfront fit and function headaches
- Layer on capabilities like automation and high-pressure coolant systems
- Add advanced workholding without re-engineering
Built for harsh environments and demanding cycles
Stronger components enable longer unattended cycles and reduce fatigue from manual intervention or unexpected stoppages. Hennig’s standard builds are designed for harsh environments and demanding cycles—without upcharges. You can count on:
- Thicker sheet metal
- Reinforced conveyor chains
- Robust sealing
Fit your machine. Fit your process. Fit your future.
Your system will easily fit your current operation while remaining scalable as your needs change. Sales engineers start with the parts you’re running and the cycles you're targeting, then tailor additional recommendations based on your goals, including:
- Futureproofing for new automation
- Enabling volume and capacity growth
- Maximizing part quality and tolerance capabilities
