CNC Tombstones
QUALITY IS BUILT ON A PRECISION FOUNDATION
AMROK's tombstones are 100% American-made with some of the industry's tightest tolerances. We firmly believe in providing durable foundations that can withstand the test of time, and offer limitless workholding possibilities for your future. Our expertise lies in the design, manufacturing, and testing of workholding foundations tailored for 3-axis, 4-axis, and 5-axis CNC machines.
Why Hennig
What Makes Us Different
Whether you’re running one machine or filling a WorkFlow pallet system, we offer CNC tombstones that exceed precision and repeatability requirements.
Alphanumeric Grid for Faster Loading
AME's alphanumeric 2" precision grid, provides consistent setups for easy repeatability.
Hole Plugs Preinstalled
Our tombstones come with hole plugs preinstalled into our grid to prevent chip build-up and provide easy cleaning.
Advanced Materials
Our CNC tombstones come in a variety of materials, such as cast iron, epoxy mineral, and aluminum.
CMM Inspection for Part Accuracy
Our fixtures are checked using large scale, state-of-the-art CMMs to ensure the tightest tolerance requirements. CMM reports available upon request.

What is the best tombstone material for your application?
Because tombstones support the workpiece during machining, their dynamic response becomes part of the entire system. The goal of this whitepaper was to measure the dynamics individually and then as part of a machine setup.
All tests were conducted by Dr. Tony L. Schmitz, a world renowned mechanical engineering professor at the University of Tennessee, Knoxville and joint faculty at Oak Ridge National Laboratory, who specializes in machine tool research and manufacturing engineering.
Review this whitepaper to learn more about what tombstone material best suits your application.

How Much Is Setup Time Costing You?
Every changeover means idle spindle time. Multi-part fixturing slashes setup frequency — so your machines spend more hours cutting and less time waiting.

Based on 250 working days/yr. Multi-part fixturing reduces changeover frequency so your spindle spends more time cutting.

Frequently Asked Questions
The easiest way to get a quote is by using the "Request Quote" button found on the site. If possible, give a clear definition of the part number and quantity requested. Email and phone requests are also accepted.
- AMROK Foundations (tombstones, grid plates and trunnion tables): In addition to the part number you’re interested in, tell us your machine make and model.
- Custom Fixture Design and Build: Use the "Request Quote" button, and we’ll contact you directly. We’ll likely need prints and models of your parts at some point and will be happy to sign an NDA if needed.
Standard Products: You’ll receive the quote within 1-2 business days.
Custom Design and Build Workholding: These quotes can vary, depending upon design inputs and engineering requirements/workload. Our team will follow up and give you an estimate on how long your quote will take.
We can do both! More than 95% of tombstones are cast iron, but we do cast aluminum, epoxy mineral, and aluminum and steel weldment, depending on the application and its requirements.
Tombstones: We keep stock of commonly ordered castings in specific sizes. We take these castings from stock and machine to your specification within 2-3 weeks. Our team generally does not stock finished tombstones.
Design and Build Fixtures (manual, pneumatic or hydraulic): Projects for design and build can take 6-8 weeks or longer depending on the specification and the duration of the design and approval process.
Each tombstone and/or design and build fixture is inspected on our CMM’s to verify compliance to specification. Design and build fixtures have an additional approval and validation phase with the customer.
We can use a variety of brands depending on the specific application or customer preference. In addition to integrating our own products, our team utilizes fixturing options from our Build on the Rock (BOTR) partners which can be found here.
There are many different variables that are considered when choosing a tombstone material. Review our whitepaper on Tombstone Testing for Dynamic Performance compiled by Tony Schmitz, PhD. to learn more about how to choose the best material for your application, including analysis on vibration, damping, and more. Read it here.
- Custom Hydraulic Fixtures start with AMRH-XXXX or BOR-XXXX
- Custom Manual Fixtures start with AMRM-XXXX or BOR-XXXXX
- Custom Pneumatic Fixtures start with AMRP-XXXX or BOR-XXXX
